This is the case when big troubles start small. The wood-boring beetle is small, but it can cause considerable problems, and a large population can cause big problems. Furniture and floor coverings, window frames, doors - everything where a miniature insect can penetrate, gnawing labyrinths of passages in wood, is at risk. What you need to know about an insidious pest, what to do when detected - signs of appearance in the house, effective means and methods of destruction, antiseptics, impregnations, insecticides.

Insects can appear in any house or apartment, even a very clean one. Moreover, they are almost everywhere - sometimes there are only a few of them, people may not even realize that they have neighbors.
These insects are not always harmful and dangerous, although in large numbers they can cause a lot of trouble. There are also bugs in the house. Which of them can be found in your home and why are they dangerous? In order to get rid of insects from a wooden house, you need to know the enemy by sight.
Risk area
Insect larvae require food. Some homes have more of it due to risk factors.
- Living a long-haired animal in the house. The wool that remains everywhere is an excellent breeding ground.
- Availability of book collections. Then you will have to take care of a safe binding for your treasures.
- The house is decorated with stuffed animals and birds. They will 100% be a hotbed for the spread of parasites.
- The cabinets are full of furs. If the bugs have not yet made themselves felt, it means that the house is damp and cool, the eggs are simply developing slowly.

Types of bugs in the house
The following types of beetles can be found in houses:
- beetle grinder (furniture, grain, grain, etc.) - damages food supplies, wooden products, wallpaper, etc.;
- springtail - damages indoor plants;
- silverfish - a safe but unpleasant tenant that lives in damp places in the apartment;
- small flour beetle - damages cereals and pasta;
- leather beetle - damages carpets and clothes;
- book louse is a rare guest in apartments, damaging old books and products that contain paste (for example, wallpaper);
- shashel - damages wood;
- bark beetle - damages wood;
- wood-boring beetle - damages wood.
Each type of beetle in the house is worth considering in detail.
Grinder beetle

These beetles pose a serious threat to furniture. They can destroy wooden structures, cardboard, plywood, and books. People believe that grinders are all beetles that harm wood, but they must be distinguished, for example, from the same bark beetles that are fought in other ways.
Borer beetles are a large family of small beetles that may or may not pose a threat to furnishings. Furniture (house) grinders can destroy an entire wooden house. In the old days, they terrified residents with a sound similar to the ticking of a clock - they were even called “death clocks.” The fact is that grinder beetles in large numbers can undermine wooden structures so much that the house collapses, burying people underneath it. They are also capable of destroying expensive wooden furniture, parquet flooring, books, door and furniture frames, picture frames, etc. in a short time. Bread and grain grinders damage not only the corresponding food products, but also spices, books, zoological collections, and herbariums.
grinders in flour
It is easy to suspect the presence of grinders in the house - when gnawing wood, they make a characteristic ticking sound. Externally they are discreet, black or brown, ranging in size from 2 to 9 mm. The body is elongated, cylindrical, the head is tilted down and covered by a protrusion of the pronotum.
Read our article: Ticking sounds and clicks in the house - what to do?
It is necessary to use highly toxic substances in well-ventilated areas. It is important to remember that their use can cause harm to humans through prolonged contact. .
It is much easier to take preventive measures - to treat wood and wooden furniture with special antiseptics that protect the wood from various insects.
We fight wood pests. Personal experience
Wood is one of the most common building materials. It is used to build houses, build rafter systems, and use it to make designer furniture. It is all the more offensive to see how wooden structures are attacked by insect pests. Indeed, in addition to deteriorating the aesthetic appeal that inevitably awaits a wooden house, pests will reduce the performance characteristics of the tree to zero. We suggest looking at the problem of beetles from a different angle and, based on the experience of users of our portal, find out:
- Can insect pests “eat” a log house?
- Where does the fight against insect pests begin?
- What preventative measures can prevent wood infection;
- Are all insects dangerous for wooden structures?
- What to do if a log in an old house is eaten away by a beetle.
Insects in logs at home: theory
Bark beetles, wood borers, longhorned beetles and woodcutting beetles, furniture and house grinders, etc. – any developer knows what it is. You can write a separate article about each type of insect pest. And any unprepared person who decides to delve into this topic will have his eyes filled with dozens of different types of insects. Let's try not to get confused.
In order not to go into the jungle of entomology, we remember this rule: the main danger to wooden structures is the larvae of insect pests that feed on wood and make passages in it. The visible part of the wood damage is the emerging adults.
The development cycle of an insect from larva to adult can last 2-3-5 or more years. If in timber, beams, etc. weekend done, so-called. flight holes having a larger diameter than the entrance holes (which are made by the larvae when they penetrate the wood), which means that we are dealing with long-infested wood.
Infestation of wood by larvae could occur both at the stage of wood harvesting (infected wood was used) and directly at the construction site, during the process of building a house.
Edged and unedged boards with bark were stored in one stack. Or, during the process of stripping the bark, it was placed in a heap next to the already finished boards, although according to the rules, the bark must be burned.
You can understand that there are “uninvited guests” in the log house by the following signs:
- Traces (mounds) of wood flour (dust) on the floor, located next to holes in the wood;
- Visible traces of passages under the bark (such boards - with the wane not removed, are often used as sheathing on rafter systems due to savings);
- A rustling sound coming from the walls. Moreover, the localization of the larva can be determined by the degree of noise. If the noise is heard during the day, then the larva is swarming under the bark, because the sound, due to resonance, is heard at any time of the day. If only at night (when all extraneous noises subside), then the larva is located in the thickness of the wood. Much depends on the thickness of the boards or timber.
Moreover, there is no 100% guarantee that pests will not appear in a log house, even if the wood has been pre-treated with special compounds. The standard, “to deflect the owner’s attention,” sluggish spraying of boards with a spray bottle (as is often done at a construction site) does not give a pronounced effect, because the composition is applied only to the surface and cannot reach the deep layers of wood where the larvae are already located.

I've been waging a war against bugs for two years now. In the evening I heard a crunch behind the cabinet, pulled it aside and saw a 5 mm hole in the log. I worked with a chisel and found that 5 white larvae of different sizes lived in an area of approximately 1500x120 mm. The largest reaches 25 mm in length. Moreover, they “worked” on an area that I had previously treated with anti-blue impregnation. The first time my wife and I heard beetles was about 5 months ago. I think these are white larvae of different types or ages, and I can’t figure out what to do next.

I built a house with wooden partitions between floors. The wood I used was dry, only bitten by beetles in some places. Therefore, to be on the safe side, I decided to treat it with a homemade solution made from resin dissolved in gasoline. I soaked everything up “from the heart.” The tree turned black. The house under a roof, with windows, a hemmed ceiling, plasterboard partitions, has been finishing for a year now. One day I entered it at night and heard scraping sounds. I started poking around in the place where the old boards were and discovered beetles and their larvae. We ate about 1 meter of the treated board. And there are still holes. Now I think that we need to remove the tree and pour concrete partitions.
Also indicative is the example of our user with the nickname ArtemTema85. He built a wooden house. During its construction, everything was properly impregnated with protective impregnations against bugs and antiseptics. The strapping was made from 150x150 timber, purchased at the nearest construction market. There were holes in it from bugs, but the seller assured that it was the so-called. flight holes, and all the beetles were gone. The main thing is to saturate the wood with an antiseptic, just in case. This is what ArtemTema85 did with his own hands, filling all the holes with the compound twice. After which he painted the timber and, after waiting for the house to settle, began finishing it. Having finished with this, I moved into the house and discovered fresh holes with “flour” in the same seemingly well-treated timber. The user additionally poured a concentrated solution into them from a syringe and now thinks about what to do next: jack up the house and completely remove the damaged beam, etc.
All three cases are indicative. Usually, the first thing that comes to mind in such cases is to resort to radical measures. Fill everything with chemicals, tear it down, replace it, call disinfectants, disassemble and reassemble, etc. But in the war against beetles, the main thing is not to rush to grab an ax or a canister of antiseptic. We need to understand who we are dealing with and, based on this information, decide what to do next.
How to deal with wood pests
The first thing to remember is that bugs can chew on your house, but they won’t eat it. It is not termites (an insect pest common to wooden houses in North America) that pose a real threat to wooden structures.
MitkaFORUMHOUSE user
I was wondering if anyone had seen a house that had been eaten away by beetles. Me not. I say this from personal experience. I have bugs in my house, but every year there are fewer and fewer of them. I treat the wood with an antiseptic and seal the flight holes with sealant, but these are far from radical measures.

In my opinion, even in the worst case scenario, the beetles will not “devour” the house, nothing will collapse, and the strength of the structures will remain unchanged. Over time, the larvae will turn into beetles, they will all come out and fly away. These are not termites. Beetles only spoil the appearance of products and make noise when they gnaw on wood. You just need to seal the exit holes and paint the wood. In attempts to resort to radical alterations - jacking up the house and changing the beams - you can ruin more. Go to the nearest village, look at the log houses that are a hundred years old - they are all full of holes, but they still stand perfectly to this day.
A new house built from fresh wood is a “tidbit” for beetles. As the tree dries out, its moisture content decreases, it begins to harden and loses its attractiveness to beetles.
There may be a danger from the activity of beetles (more precisely, their larvae) if they begin to wear away the load-bearing beam, which does not have (due to design errors) a safety margin. The longer a house stands, the fewer bugs there are in it. The main thing is that the wood does not rot, mold, or become damp, because... such conditions attract wood pests.
This does not mean that pests should not be dealt with! You need to fight, but you need to do it thoughtfully, knowing well the habits of your “enemy.”
Even if you find one or two beetles in the house, this is not a reason to panic. You shouldn’t immediately run to the store and blindly buy a protective composition. Before drawing conclusions, you need to carefully inspect wooden structures for passages and wood flour. Listen to see if there are any extraneous sounds at night. Check the sheathing and rafters to see if there is any bark left on them. Only a comprehensive check and detection of indirect signs of pest activity can provide a clear picture. It is also worth checking your supplies of household groceries - flour, cereals, spices, because... beetles (flour beetles) could crawl out of there.

In principle, all pest beetles are similar in their morphology, and the methods of controlling them are the same. They may differ from each other in size, color, length of the whiskers, and the duration of the larval maturation period. There is only one principle - we determine whether we are facing a wood pest or not.
To determine the type of beetle, we catch it or photograph it, then search the Internet for a similar picture of the insect. We find and then read its description. If you find it difficult to identify the type of beetle on your own, you can contact the experts on our portal.
Once we have determined that the beetle is a pest, it must be destroyed using special tools and methods for treating wood. In this case, adult individuals, as they emerge from the wood, will die, and new arrivals from the “street” will not lay larvae. This is a long process, it can take a year, two, three or more years. To cope with this larval scourge, you need to understand how the world of beetles works.
AmetistFORUMHOUSE user
Let's take woodcutter beetles. They have their own specialization - someone finishes off a sick tree. The rule works: if a tree “accepts” larvae, then it is sick, because healthy ones, secreting resin, immediately kills them. Some of these beetles live only in dead wood, i.e. felled tree.
Woodcutters (some of them) do not need bark. They need peeled wood - this is cleaned for them in nature by longhorned beetles, which need bark. Beetles also require time to mature and grow. During this period they need to eat something.
The standard development cycle of a beetle in wood is 2-3 years. If it happens that the house is built from infected wood, and larvae live in it, then (if this thought and rustling does not bother you) you can wait until they mature and the beetles themselves fly out. These holes are then sealed with sealant and painted over. The main thing is to prevent secondary contamination of the wood.
So that's who gnaws on the logs in the bathhouse!
Let's consider this example: under the bark in a new rafter there is a purple longhorned beetle. It develops only under the bark. The larva will exhaust the entire phloem, the bark will fall off, and the beetle will fly away, and there will be no new infection. The boards will not be damaged. To calm your conscience, you can tear off the bark where your hand can reach.
Ametist, Moscow.
Over time, the wood will dry out so much that it will become completely “unpalatable” for longhorned beetles, and only furniture beetles can live in it. In this case, infection occurs through old furniture.
The most important thing is to prevent the wood from getting wet and causing rot, because rot attracts another type of longhorned beetle, which does not require bark for development. In addition, this type of beetle will introduce mold spores into the tree, which are necessary for the development of larvae. Moreover, mold is a greater enemy for wood than beetles, because... leads to the destruction of wooden structures.
Hence the following rule: it is not enough to get rid of one type of insect pest; preventive measures are necessary that will make the wood unattractive to other types of beetles.
Preventive measures
Preventing a disease is easier than treating it. As mentioned above, different beetles eat different types of wood. If a wooden structure is constantly in a humid environment, the vapor barrier is not installed correctly, the temperature balance is disturbed, and the wood is not ventilated, then all the conditions are created for the development of mold. Pests love this wood. So, one violation leads to another, and the tree undergoes accelerated destruction. This must be avoided.
The best solution for a wooden house would be a ventilated facade. Moreover, we adhere to the following rule: a wooden house has wooden cladding. In this case, we do not lock the wood under plastic siding and still allow it to “breathe.”
From our article you can learn how to make a wooden facade with your own hands.
Conclusion: we make sure that the tree remains dry, is very well ventilated, and is not flooded with rain.
In this case, within 5 years, the moisture content of the wood will decrease, and such a tree will no longer be suitable for colonization by woodcutter beetles. But this is no reason to relax! This kind of wood is “to the taste” of wood-boring beetles.

Grinders are fairly prolific insects with a short generation period (for all phases of development). Their departure from wood (death) is theoretically possible at low wood moisture levels (less than 20%), but some of the species (furniture grinder) can also develop at carpentry humidity (from 8%).
To combat them, you can do this: we identify the affected area of wood and impregnate it with special protective compounds. To kill insects in the thickness of the wood, we make several drillings with a drill with a diameter of 3-5 mm. We drill holes not only in the area of visible damage, but also grab about 200 mm to the sides. The drilling depth is 3/4 of the thickness of the wood being drilled. We drill holes at the intersections of an imaginary grid with a pitch of 40-50 mm. We drill the tree at an angle to the horizontal. In this case, the solution will not leak out of the holes. Then we inject into them with a syringe a special solution designed to eliminate insects, which provides long-term preventive protection. Fill each hole with solution 3-4 times.
You can drill holes less often. In this case, we plug them with rubber stoppers from the droppers, through which (piercing them with a needle) we periodically inject the solution. This will ensure long-term impregnation and increase the spread of the insecticide in the wood.
Insect pests and insect helpers
The idea that “bad” beetles will fly in from somewhere in the forest and begin to “eat” your home at an accelerated pace is a myth. We, without knowing it, can create all the conditions for pests to come to “visit” us. Here are just a few of these conditions:
- The most common reason for the appearance of beetles in a house is the use of infested damp wood with uncleaned bark during construction;
- Improper use of the house or purchase of an old house that has not been lived in for a long time;
- A leaky roof leads to leaks. Due to improper insulation, poor ventilation, improperly installed hydro-wind protection, etc. The humidity level in the house increases. The tree rots, gets wet, and rots.
From the beetle’s point of view, this is no longer your home, but a place where it was invited to live, and where it can lay its larvae and raise its offspring.
LEXFORUMHOUSE user
During the construction of a wooden house, poorly dried, and most often freshly sawn, raw wood is often used. He still needs to dry and dry. The tree is sawn, cut, chopped, which means there is a strong smell of wood. It attracts pests. At this stage, you need to use external wood treatment products. This will avoid infection. Once the wood dries, it will harden and become less attractive to insects.
Not all insects can be considered pests. The ichneumon wasps infect the beetle larvae with their eggs and thus destroy them.
PIM56
An effective protection against insects that use wood as an incubator to hatch their offspring is to paint the wood with thick-film coatings. This creates a barrier for them to recognize wood.
There are also simply useful bugs that should not be killed.

I recently sawed an old birch tree (which had been lying on the site for 2 years) for firewood on my property and saw a beautiful woodcutter fly out of the log. This insect does not pose a threat to a wooden house, because... its larvae live in rotting birch, recycling it in this way. This woodcutter pollinates many types of flowers.

Long-horned beetle
This slideshow requires JavaScript.
One of the oldest inhabitants on Earth, the long-horned beetle has many varieties. The size of the insect can vary from a few millimeters to several centimeters. Whiskers often exceed body size by 10 times. The larvae reach 3 centimeters in length. In our area, you will most likely encounter a mustachioed black beetle with a green-blue tint. During its development, the longhorned beetle goes through several stages - egg, larva, pupa and, in fact, the beetle.
Longhorned beetle and longhorned beetle species are here!
Shashel
You can read more about the insect in the article: How to get rid of shashel.
Chashel often refers to beetles that damage furniture. Often all these insects are referred to by one term, although in fact the shashel is a black barbel. Externally, longhorned beetles differ from other grinders in appearance. They are black, with whitish patches, and have a large head with antennae and wings. Body length – 15-40 mm.
The difference between them and other insects that attack wood is that they prefer coniferous trees - fir, spruce. They live mainly in coniferous and pine forests.
The methods of control are the same as with other beetles that damage wood. They love fresh wood and can be found in warehouses, from where they enter homes.
Bark beetle
Read more about it in the article: how to get rid of the typograph bark beetle
These beetles often live in wooden houses, posing a serious danger. These black-brown bugs, no larger than 1 cm in size, gnaw many passages in the wood, destroying the product.
This slideshow requires JavaScript.
They enter the house along with building materials or from neighboring trees. Bark beetle larvae are so voracious that the appearance of just one infected board in a house is enough for them to destroy the entire log house - this will take only a few years.
If single burrows are detected, you can inject special insecticides (“Anti-bug”, “Tree Healer”) directly into the burrows with a syringe, and then cover up the holes. Then all wooden elements of the house should be treated with antiseptics in order to get rid of insects remaining in undetected passages.
If the affected area is large, you need to stick a knife or awl into the damaged area. If the tool enters easily, then the damage is significant. In this case, the affected material must be removed and burned along with the pests. Then treat healthy wood with insecticide and antiseptic and place a new beam in the excavation site. If the wood is strong enough, but the damaged area is large, insecticide treatment should be repeated several times.
Getting rid of bark beetles is quite difficult, so it is better to take preventive measures. First of all, you need to buy proven wood that has been treated with an antiseptic. Also, for the purpose of prevention, it is necessary to periodically treat all wooden elements of the structure (both external and internal) with antiseptics (Senezh, Aquatex, Ecolan, Woodpecker, etc.), and if a lot has passed since the last treatment time - and insecticides.
Ants

At different times of the year and in different regions of the country, in an apartment, and even more so in a private house, you can often find representatives of various species of ants. Very often, ants in an apartment are random guests, carried on clothes or with things. Among them there are insects of different sizes and colors. However, the only real pest in an apartment is the so-called pharaoh ant - an independent species of heat-loving small ants, which in our latitudes cannot live anywhere other than residential heated premises. These red ants in the apartment are a real problem: they are numerous, spoil food, can carry pathogens of various diseases, and besides, they are extremely difficult to remove. One colony of house ants can contain several dozen queens and up to 350 thousand workers. The reasons why red ants appear in an apartment, although not numerous, can be found in almost any home. That is why small red ants are successfully conquering more and more new areas and are likely to appear in any apartment, even the cleanest one.
wood beetle
A more detailed description in the article: Woodworm - how to get rid of it?
Small, dark bugs with wings are often confused with ordinary, harmless flies. But they can destroy wooden structures in just a few years.
This slideshow requires JavaScript.
They spend almost all their time in the passages they have made inside the wood and fly only during the mating season. That's when you can see them - flying around light bulbs in the evening and crawling on surfaces during the day. The larvae live in wood for up to 17 years, and during this time each one makes passages up to 40 km long in the wood.
To destroy pests, special insecticides are used that are able to penetrate into the treated surface. Light preparations, after spraying onto damaged surfaces, destroy insects on the surface and lure others out of hiding. More powerful preparations quickly destroy even large colonies of pests, but after treatment with them you should not enter the room for several hours - they are toxic.
In order not to have to fight with various beetles that destroy wood, it is better to take preventive measures - the same as in the case of bark beetles.
Review of the best products
Given the wide range of modern insect control products, it is often extremely difficult to make a choice.
To make this process as easy as possible, below is a brief overview of the most effective options:
Aerosol Combat
Containing insecticides such as permethrin and tetramethrin, it is one of the most well-known and effective remedies for home use. It allows you to destroy all types of crawling insects and arthropods, while being able to poison even their eggs and larvae. Combat does not have a pungent chemical odor; instead, a pleasant floral aroma will remain on the treated surfaces. The cost of a can with a volume of 500 ml is about 400 rubles.
Aerosol "Raptor"
It costs less than Combat, but is no less effective. Available in 350 ml cans, the approximate cost is 250 rubles.
Get insecticidal soap
Effectively gets rid of ants, bedbugs and cockroaches. You can even treat carpets with it; the product can then be easily washed off and will not leave stains behind. The approximate price of such soap is 400-420 rubles.
Avalon product
It is an emulsion concentrate from a South Korean manufacturer. The main advantage is the versatility of the solution obtained from it, which destroys all crawling and flying insects and provides protection against them for several weeks. The cost of one 50 ml bottle is about 600 rubles.
Foresight tool
It is also an emulsion concentrate, the main active components of which are cypermethrin and fenthion. First of all, the drug is intended to kill ticks, but it also shows good effectiveness against other crawling insects. The price for it is 350-400 rubles.
Means "Xulat"
Made in Spain, it is intended for preparing a solution based on it. The composition includes various insecticides, which allows you to destroy even insects with developed immunity to certain components. A 30 ml bottle costs about 500 rubles.
Product "Delta Zone"
It is one of the most effective modern remedies, the main active ingredient of which is deltamethrin. A solution based on it shows equally good results in exterminating all types of flying and crawling pests. The cost of a 50 ml bottle is about 700 rubles.
Aerosol "Super Cobra"
Against crawling insects, its quality and effectiveness is confirmed by the fact that it is used by many service specialists for the destruction of these pests. The cost of one bottle is about 230 rubles.
Cucaracha
It is a concentrated liquid preparation that is capable of exterminating all types of insects. The rules for preparing a solution based on it are indicated in the instructions for the product and vary depending on the type of pests being controlled. The price of one bottle is 450 rubles.
Devices emitting ultrasonic waves
They are the most innovative devices for fighting insects. The Belgian-made Weitech WK0523 model, among other things, also affects rodents. The package includes three devices that can be placed in different rooms to increase the area covered by the protective effect. The cost of this equipment is about 4,000 rubles.
Flour beetle
These are small reddish-brown bugs a few millimeters long. They spoil cereals, flour, dried fruits. They usually enter the home along with contaminated products.
If a beetleworm is detected, you must throw away all the stocks of cereals, pasta and dried fruits in the house. These bugs can also live in baseboards and window frames, so after eliminating the products you need to thoroughly rinse all surfaces with a vinegar solution. Skirting boards and other surfaces that do not come into contact with food can be treated with chemicals.
Carpet beetle
These small bugs gnaw carpets, fur, various natural materials (leather, hide, wool), fabrics, and grain. They pose a danger not only to things, but to people and animals, as they bite painfully and can carry infections and cause allergies. The bite site should be treated with alcohol and hydrogen peroxide.

In appearance they resemble grinder beetles. But unlike them, they also pose a threat to humans. Therefore, if they are discovered, it is necessary to take immediate action - it is advisable to call our specialists who are professionally involved in the destruction of insects.
Carpet beetles love dry and warm places, so they are usually found under baseboards near radiators, on window sills, in floor crevices, and cabinets. It is difficult to get rid of skin beetles, so it is better to take preventive measures - for example, putting moth sections in cabinets with the smell of lavender, which they do not like. These bugs also cannot tolerate the smell of tobacco, wormwood, and tansy.
To get rid of skin beetles, you need to use special chemicals . Infected items should be taken out to the balcony - these beetles and larvae die at temperatures below +7 degrees.
How to get rid of it: traditional methods
Larvae are the culprit behind damaged wood, but they live deep below the surface. Getting rid of them is not so easy, and it is better not to delay treatment. To combat larvae, the following methods are chosen:
- Freezing. Under the influence of low winter temperatures (-5-10°C), the larvae die within 2-3 days. If winters in your region are cold, then pests are unlikely to grow in the outer walls of wooden buildings. This is a convenient way to disinfect furniture: take it out into the yard (or onto an unglazed balcony) and leave it for several days.
- Replacement of damaged fragments. Sometimes the easiest way is to replace a damaged section of trim or piece of furniture. The unusable part is burned, and the remaining surfaces are carefully inspected to see if pests have reached there either.
A damaged fragment cannot always be replaced Source wikimedia.org
Book louse
Also called the book hay eater. They have a long body and a large head. They love warmth and high humidity, so if they are detected, it is recommended to reduce the humidity in the room.
Book lice are common in nature - they live in bird nests and rodent burrows. Rarely found in homes - mainly in libraries and museums. These insects feed on plant and animal remains, as well as paste. In the old days they caused a lot of trouble because paste was used in the production of books. They are not interested in modern books, since synthetic glue has begun to be used. They are not dangerous to humans and animals.
clothes moth

Moths inhabit houses and are a household pest, whose caterpillars spoil fabrics by eating them and gnaw the silk upholstery of furniture. Only caterpillars cause damage to products, because adults lack gnawing type mouthparts. In the dark at night, adult moths fly towards an artificial light source. According to some data, house moth caterpillars also feed on substances of plant origin, namely grains of wheat, barley, oats, corn, flour and dry bread. House moths are widespread worldwide; this species of lepidoptera is a serious pest in human homes. They feed on clothing, carpets, blankets and upholstery, as well as fur, wool, feathers and miscellaneous items such as animal bristles used to make toothbrushes and piano fibers.
Silverfish
Silverfish are often confused with woodlice. They have an elongated flat body, with long antennae. Covered with scales, body length up to 19 mm. Safe for humans and animals, but can damage books, clothing and food. They often live in the bathroom, as they love dark and damp places. During the day they prefer to hide in the cracks of baseboards, frames, cabinets, etc.

If there are few silverfish in the house, you can try installing a sticky trap - for example, for cockroaches. To attract silverfish, you can put a piece or other starch-containing product inside.
You can also fight silverfish with insecticidal aerosols based on pyrmethrin . It is important to remember that they should not be used in food storage areas. You can also sprinkle diatomaceous earth overnight on areas where silverfish are common, and then vacuum it up. It is important to keep children and animals away from the treated area.
Cockroaches

The remains of cockroaches are, along with the remains of cockroaches, the most numerous traces of insects in Paleozoic deposits. Additionally, cockroaches are the earliest known Polyneoptera, possibly descending from the ancestor of the entire subcohort. They have always been and will be on Earth. There are more than 4,600 known species of cockroaches; are especially numerous in the tropics and subtropics. There are 55 species on the territory of the former USSR. In recent years, there have been popular reports about a decrease in the number of certain species of cockroaches in the CIS (they say they have completely left apartments in St. Petersburg and some other cities - no one was upset, but the reasons are interesting). A number of cockroaches live in human dwellings, being synanthropes, for example, the red cockroach (Prusak), or the black cockroach. Others are brought with tropical products to temperate countries and sometimes take root in heated rooms (American cockroach). Cockroaches can damage food, leather goods, book bindings, indoor and greenhouse plants. Some cockroaches, feeding on various waste, including feces, are carriers of infectious diseases (for example, dysentery) and worm eggs.

Small black bugs
Small bugs with a curved back are called skin beetles . There are several hundred species, but almost all of them are harmful pests. They have spread throughout the world thanks to their ability to adapt to different conditions.
If necessary, larvae can use synthetic materials instead of organic matter. Therefore, beetles will feel great in the fleecy fabric of the carpet. However, they do not die, even if they are without food for a long time.
Carpet beetles have rough mouthparts that, in theory, can slightly damage human skin. There have even been reports of bites from these bugs. A slight red swelling appeared on the skin and itching was felt after the insect had been there. However, entomologists are inclined to believe that this is only an allergy to the harmful secretions of beetles. They do not consider living skin as food, so they will not bite.
