What is cold and hot fog for bedbugs and cockroaches?

Why are cold and hot mist more effective than regular sprays?

This disinfestation allows you to clear the room of insects quickly and for a long time.
This disinfestation allows you to clear the room of insects quickly and for a long time. The reason is the small particle size of the insecticidal aerosol cloud (30-80 microns), which is significantly smaller than with other types of products.

An insecticide with a particle diameter corresponding to the fog is sprayed by devices called fog generators. They can produce both cold and hot mist.

Hot foggers for cockroaches and other insects are also often used to kill bedbugs. These devices are characterized by the fact that they contain a special heating system. When using hot fog, an even smaller particle size of the aerosol cloud is obtained.

Among cold fog generators there are models intended for home use. But among hot fog generators there are no such ones. All such devices are intended for professional use only.

Is it even worth spending money on a disinfection unit?

It can only be truly clean and safe where it is regularly cleaned, and this is done using professional means and equipment. Today, at the peak of popularity are aerosol devices that:

• provide uniform treatment of surfaces and places that cannot be reached with conventional sprayers;
• allow cleaning quickly and efficiently even over large areas;
• are easy to use and allow you to save on operator salaries;
• do not harm the environment;
• have wide functionality.

If you care about antibacterial protection in a medical facility, kindergarten, school, office, warehouse, etc., then you cannot do without a cold or hot fog generator. But which one is better to choose will depend on the following factors: frequency and cleaning requirements, practical purpose of the premises, financial capabilities and area of ​​work.

How does cold fog kill bedbugs work?

Hot and cold mist against cockroaches and bedbugs is an effective method of controlling household insects.
It consists of using special generators in the treated room, which, under the influence of temperature and pressure, release microparticles of a specially prepared solution into the space.

The operation of such modern, technological equipment is similar to powerful aerosol treatment and can be performed in both hot and cold conditions, is low-toxic and absolutely safe for humans.

A solution containing water and insecticide turns into small droplets that can penetrate hard-to-reach places and settle on their surface. The efficiency in all respects is many times higher than when using very efficient sprayers, since this significantly saves time and effort.

Instead of slowly spraying the working solution with a regular gun, you can do the same job many times faster. Using special equipment, the result is achieved much better.

Benefits of cold fog

Important advantages of killing bedbugs with cold fog:

1. High penetration of insecticides into all areas of the room, including hard-to-reach areas;
2. Immediate destruction of harmful insects;
3. Complete destruction of cockroaches and bedbugs, as well as egg laying in large rooms;
4. Profitability;
5. Highly effective prevention of harmful insects.

Safety rules for self-processing

It is better to entrust the disinfection of the premises to a professional because the result is more reliable and the work is safer. But if you decide to get rid of parasites yourself, you must follow several rules:

• Be sure to wear special clothing with long sleeves, gloves, goggles, a hat and a respirator.
• After disinfection is completed, do not enter the room for the prescribed time depending on the treatment method.
• Monitor your condition carefully. If you feel dizziness, headaches, nausea, or burning, immediately stop the treatment procedure and leave the room. If the condition does not return to normal, you should immediately consult a doctor.
• Carpets and wall decorations should be removed.

Treating a room with hot or cold mist is not a cheap pleasure, but the result will be after the first procedure and there will be no need for repeated sessions. Compliance with the rules for preparing an apartment for disinfection and following recommendations after it is the key to quick and trouble-free disposal of parasites.

After hot treatment, you cannot stay in the apartment. But what about the neighbors on three sides? Do they also need to leave their apartments?

You can be in the room within a couple of hours after treatment, after the drug is distributed over the entire area of ​​the room and settles.

Killing bedbugs with hot fog

Destruction of bedbugs with fog can be either cold or hot.
In the latter case, the operating principle is reminiscent of a home kettle: steam is formed from the liquid, which, upon contact with the air in the room, cools and turns into fog.

The name of the method is directly related to the high temperature of the solution heated by the generator (about 70°C), at which the active chemicals work at their maximum. The higher the volume of microparticles of moisture that enters the room, the greater the likelihood that the fog will penetrate into all possible insect hiding places and ensure the release of both adults and eggs. Completely hot fog disappears 10 hours after treatment.

How does it affect insects?

This method involves spraying an insecticidal composition that is exposed to ambient temperature, causing hot vapor particles to form. They penetrate into all hard-to-reach places in the room. A stable film, which is difficult to notice on the surface, upon contact with an insect, infects it with an insecticide. In turn, the cockroach or bedbug infects the entire population and dies.

Hot fog against bedbugs, cockroaches and other insects has the following advantages:

1. Duration of action – precipitated insecticide particles kill cockroaches over a fairly long period of time;
2. Prevents the appearance and development of fungi and mold;
3. Protects the room from many harmful insects;
4. Reduces the content of pathogenic microorganisms in the air.

Most often, hot steam treatment is used in the following cases:

1. Destruction of insect pests (fleas, cockroaches, ticks, worms) indoors and outdoors;
2. Getting rid of various viruses in crowded places (for example, in public transport);
3. Elimination of unpleasant odors.

According to the owners of premises and apartments who received absolute results by getting rid of cockroaches and bedbugs, it is not recommended to open the premises within 2 hours after treatment.

Additional barrier protection against bedbugs in an apartment or house

Barrier protection includes the following measures, which are used by a professional as an additional method of combating bedbugs:

• Mechanical barriers against parasites - screens on windows in the house, traps, canopies, devices for bed legs.
• Repellers are either mechanical, natural, or chemical means that would affect the sense of smell and pulsation of an insect in which it is highly developed.
• The extermination barrier is insecticides that are applied in the form of a line, the border of which the insect cannot cross due to the toxic composition of the drug, which is detrimental to it.

To carry out sanitary work in an apartment, special equipment is used, which must include:

• loose overalls that fit tightly in the areas of the hands and feet, completely covering the body;
• mask with a respirator - you can use a soft mask-helmet that would cover the entire head;
• gloves;
• glasses and respirator separately;
• special shoes.

The exterminator puts all this on during preparation for disinfestation work and treating the apartment from parasites and removes it after treatment. He must put all his clothes and equipment in a sealed bag, and then at his sanitation station these clothes are handed over to the laundry, where the appropriate cleaning, washing and washing are carried out. In the client’s apartment or house, the disinfector should not clean his used workwear. Such safety measures help keep the environment free from the spread of chemicals.

Cold fog as a remedy for cockroaches

The use of cold fog against cockroaches is due to the fact that the working solution is distributed into microparticles. Its droplets, emitted under pressure, are larger in volume than hot steam. Because of this, they do not heat up; their temperature coincides with the air temperature in the room being treated. The microparticles first accelerate and then fall, become completely filled and remain in the air for several hours after treatment.

When filling a room with this mist, in order to prevent a strong increase in humidity, it is necessary to strictly follow the instructions prescribed by the manufacturer, which requires a preliminary reduction in humidity before starting treatment. Removing drops of spray do not leave stains or marks on the fabric.

Room treatment procedure

To obtain positive results from aerosol disinfection, it is important not only to carefully select the optimal method for its implementation, but also to prepare for the procedure itself according to all the rules.

How to prepare for processing?

• The room must be empty: the presence of people without special equipment and animals is strictly prohibited.
• Small items, electronics, dishes, and personal hygiene products must be sealed.
• It is recommended to move the furniture to the middle to free access to the baseboards.
• Carpets and wall decorations should be removed.
• To increase the efficiency of processing, you need to remove dust from surfaces and floors.
• If one of the residents remains in the room during the procedure, it is necessary to put on special equipment.

Treatment of the premises.

The exterminator carefully treats the room, paying special attention to door frames, baseboards, sofas and beds. Afterwards the doors are closed for 4 hours (cold treatment) or 10 hours (hot fog).

Cleaning the room after treatment.

After waiting the required time, wet cleaning of all surfaces in the room is carried out. Open the windows for at least an hour so that the air in the room is completely renewed. Afterwards, the person doing the cleaning needs to take a shower and unpack the preserved items.

Pros and cons of the technique

Reasons why you should use cold mist to get rid of cockroaches:

• Instant penetration throughout the entire room and a detrimental effect on cockroaches
• Without leaving any stains on the surface
• Effectively tested against cockroaches
• Environmentally friendly if all rules are followed, since the method allows you to use fewer chemicals with the same efficiency
• Ease of use of the tool itself
• Reliable

Minuses:

• The method is labor-intensive for preliminary preparation and subsequent tidying
• Quite dangerous in terms of toxicity
• Expensive

Further actions after disinfestation

After filling with chemical mist, the apartment is closed for at least 3 hours. If the parasites were poisoned using the hot method, this period increases to eight hours. Therefore, it is better to carry out this procedure in the evening, leaving the apartment closed at night.

After this, the room must be ventilated by opening windows and doors for 2 hours. General cleaning is carried out after 15-16 days. Before this, it is enough to wash only the surfaces with which residents come into contact with a soap-soda solution: kitchen tables, door handles, switches and dishes.

Floors, baseboards and walls are washed after two weeks. At the same time, curtains and bed linen from the closets are washed, and lighting fixtures are processed.

Repeated treatment is required if neighboring apartments are also infested with parasites. If disinfestation with cold fog was not effective enough, then you need to change the preparations or use another method in the form of temperature exposure.
