Ever since people learned how to arrange their homes, they have had to fight various parasites, including insects. Today there are many different anti-bedbug remedies that can cope with the problem. But since pests are adaptable, choosing a product and treatment method is not so easy. One effective spray method is cold mist. This technique involves irrigating rooms and objects with small particles of an insecticide solution. This allows you to evenly cover all surfaces with a thin layer and kill all insects.c
But depending on the type of parasite and conditions, a specific drug may be needed. We will consider the most suitable products for this type of treatment that have a good reputation in the market.
How to choose the right drug
Before purchasing an insecticide, you must clearly decide on two points - the type of parasite and the method of destroying it. In our case, we are considering a problem with existing conditions; we need to choose a cold fog treatment against bedbugs. But even in this case, some nuances should be taken into account
- composition - the active ingredient of insecticides is most often fenthion, chlorpyrifos, malathion or permethrin;
- quality certificate - the document can be asked to be presented directly to the seller;
- instructions - firstly, it must be present, and secondly, recommendations for use must be extremely clear to you;
- reviews of people who have worked with this product can be easily found on the Internet.
If you are planning cold fog treatment, check with the seller whether this or that substance is suitable for this particular method.
A well-chosen drug is half the success in the fight against bedbugs, so this issue should be approached responsibly.
Industrial refrigeration
Ensuring ergonomics in the workplace – increasing labor productivity. In our case, we ensure a reduction in the ambient temperature in the room and on work sites. The most widespread use of artificial fogging systems is observed in foundries and during construction. Thus, with proper organization and design of the system, it is possible to obtain a real temperature reduction of 150C, which has a very positive effect on the quality of work and productivity in general. In the case of intensive use of “artificial fog”, the economic effect is felt within the first year. In particular, air conditioning costs are significantly reduced, attentiveness increases, the output of products of inadequate quality is reduced, production discipline indicators are improved, and the number of accidents is reduced. Moreover, most of the problems that arise from inspections by regulatory authorities (sanitary station, environmental service, etc.) fade into the background. And the most important point is the creation of ideal, from the point of view of breathing, conditions for humans.
"GET"
This chlorpyrifos-based product is quite popular due to its effectiveness.
The drug is a microencapsulated suspension that penetrates the insect’s body, penetrating through its integument. The active substance acts directly on nerve impulses, blocking them. The pest is paralyzed and dies. In addition, a sick bug strives to return to its nest, where it infects its relatives. The following features of the drug can be identified:
- lack of specific odor;
- the presence of a residual effect, the duration of which can be up to six months;
- each bottle costs between 800-900 rubles and contains 100 ml of product, which allows you to treat up to 100 square meters. m.
The drug for killing bedbugs is not used in its pure form. It must be diluted to a certain concentration in accordance with the instructions. It is necessary to work with the product in a respirator, safety glasses and gloves. After spraying, it is necessary to ensure through ventilation of the room for 3-4 hours.
When purchasing such a drug, pay attention to the design and packaging. The product is packaged in white bottles with a yellow label. The name is always written in English letters “GET”.
Drugs with a similar effect - “Averfors”, “Agran”.
Principle of operation
A cloud consisting of tiny particles is formed in the generator by compressed air. Having high speed, it collides with a toxic substance and destroys its structure, dividing the liquid filled into the generator into microscopic parts. Then compressed air, enriched with toxic particles, is released under pressure from the generator. The mechanism is designed in such a way that spraying is carried out evenly.
"Executioner"
A product with broad-spectrum microcapsules based on fenthion. Actively used for treatment against skin beetles, ants, cockroaches, flies. Shows high efficiency in the fight against bedbugs. The “executioner” completely paralyzes the insect, resulting in its death. The drug does not pose a danger to humans and animals if used according to the instructions. A small bottle of the product is only 5 ml, which is enough to treat an area of 5 square meters. m. Treat surfaces with which insects come into contact with an insecticide.
"Kukuracha"
The liquid contains two strong substances - malathion and cypermethrin. The drug is bluish in color, which makes it easy to distinguish it from fakes. The unique composition allows you to avoid addiction among pests. This makes it possible to repeat treatments using the same product. The drug is very toxic because the concentration of substances is high. Special care must be taken when working. It should be taken into account that the product has an unpleasant odor and the room must be ventilated after treatment. The positive effect of “Kakarachi” will be noticeable already on the 3rd day and lasts up to 30 days. The drug is available in 50 ml bottles (concentrate) and costs about 250 rubles.
What else do you need to know about using fog generators?
It is worth remembering that treatment for bedbugs and other insects does not depend solely on the generator. Choosing the right insecticide plays a huge role. Now there is a wide selection of good products that destroy bedbugs, cockroaches or various types of pests. The insecticide should remain relatively safe for pets and people. It is desirable that there is no persistent odor if the owners do not plan to change the furniture after treating the room. Reading reviews about this method of fighting insects, there are references to an unpleasant odor that could not be eliminated for several weeks or even months.
Bed bugs: how can you get rid of them at home?
Only some insecticides have an ovicidal effect and can kill insect eggs. And there can be several hundred or thousands of similar eggs. Therefore, the effectiveness of the treatment depends on the product, which should have a prolonged effect. Thanks to this, the larvae will die after contact with the insecticide that remains on the surface.
When working with generators, you should always take into account that disinfection involves the use of poisons, so it is better to take care of personal protection in advance. When treating a room for cockroaches, you should use a high-quality respirator, rubber gloves and goggles. A protective suit is advisable, although thick clothing that covers the entire body may be an alternative.
Small electronics, dishes and other items should be placed in sealed plastic bags. However, it is worth examining them in advance for the presence of insects or their eggs.
"Cifox"
Transparent yellowish emulsion with cypermethrin. “Tsifoks” is popular among services providing professional pest control. Effective against bedbugs, cockroaches, ants, flies and other pests. The drug has a long-term effect that lasts up to 3 months. Available in bottles of different sizes, the price varies depending on the size from 150 to 400 rubles. It is very difficult to buy the product; it is mainly used by SES authorities. Analogs - “Tetrix”, “Medilis” series.
"Foresight"
One of the safest drugs (4th danger group), which has earned its popularity. It is a suspension with suspended particles of permethrin. The toxic effect applies to insects at any stage of the life cycle, including eggs. The disadvantages include gradual action. The effect after treatment may not be noticeable immediately, so it is recommended to repeat irrigation every 4-5 days for a month and a half. The effect of the drug lasts up to 15 days. This product is recommended to be used in conjunction with barrier protection methods. The price for 1 liter of the drug ranges from 600 to 100 rubles.
"Fufanon"
Organophosphorus agent based on malathion in the form of a transparent emulsion. The action of the drug is fumigation and contact. The peak activity of the substance occurs in the first 2 hours after spraying, but the residual effect remains for another 30 days. "Fufanon" has different forms of release
- ampoules of 5 ml;
- 1 liter bottles;
- 5 liter canisters.
The price starts from 80 rubles and depends on the volume.
A relative disadvantage of the drug is that it only affects adult bedbugs. In this regard, there is a need for repeated treatment after 14 days to destroy the larvae.
Automatic greenhouse ventilation
Full ventilation of greenhouses allows you to create a comfortable microclimate and accelerate the ripening of vegetables and fruits. Full ventilation in a polycarbonate greenhouse allows you to quickly remove air treated by plants and does not allow excess moisture to accumulate in the soil.
Types of ventilation
If a fruit-bearing plant is not properly cared for, it will not bear fruit and will die. Currently, there are two types of ventilation of artificial structures:
- automatic;
- manual (mechanical)
Automatic ventilation can be done:
- bimetallic;
- electrical;
- hydraulic
The manual version of ventilation (ventilation) involves the presence of a different number of vents and doors; it is simple and accessible.
Attention! Regardless of the ventilation system, it is assumed that manual ventilation is possible by closing and opening the vents.
The advantages of such air ventilation for homemade greenhouses:
- No costs for special devices.
- Saving electrical energy.
- Budget, availability of the device. Such ventilation in a polycarbonate greenhouse can easily be done with your own hands.
- Install the desired number of fans and relays along the entire length of the greenhouse.
- Correct installation of such greenhouse ventilation with your own hands makes it possible to adjust the air flow density. In case of significant overheating or sudden cooling of the air, you can change the fan operating mode. The exhaust fan, when creating a slight vacuum, removes hot air outside, instead of it a fresh air flow enters the greenhouse.
- Thermal relays are considered reliable devices that give clear readings. Modern thermal relay models require setting parameters that allow them to turn off and on at certain times.
- Pour liquid into a certain container. In the process of heating, gradual expansion occurs, and upon cooling, partial compression occurs.
- As the volume of liquid increases (when heated), the window opens. When the volume of water decreases, ventilation stops. The thermometer is a vessel installed inside the greenhouse. The compensator is a container fixed outside the greenhouse structure. In order for the containers to become communicating vessels, hydraulic hoses are used (they connect the outer and inner containers to each other). When the pressure in any container increases, an instant reaction occurs - normalization of the indicator, leading to an upward movement of the transom.
- The transom will never reach its maximum position, so ventilation is carried out smoothly and leisurely.
- This process is inertial, that is, in the event of a significant decrease in the outside air temperature, closing is performed very slowly. For plants sensitive to cold, this is enough for their complete death.
- In such a system there are no windows, which is inconvenient when growing many garden crops.
- Easy to install.
- Reliability of the system, its durability.
- Inexpensive maintenance, there is no need to constantly monitor the process.
- Easy to install.
- Long operational period.
- Minimum system cost.
- The window for ventilation is located in the upper part, in which case a sufficient amount of flowing air will flow inside.
- If the greenhouse is installed incorrectly, there will be drafts inside, which will negatively affect the plants.
- It is advisable to install forced ventilation systems in polycarbonate buildings. As a result, new air masses will be optimally adjusted for the selected time period, and the necessary microclimate will be formed in the greenhouse.
- To remove exhaust air, you will need a standard hood.
The disadvantage of manual ventilation is the mandatory presence of the greenhouse owner.
Those who do not have the opportunity to constantly care for plants try to use automatic greenhouse ventilation made by themselves. Advice! It is not necessary to look for a specialist to create ventilation; it is quite possible to cope with such a task on your own, using a ready-made algorithm of actions.
Among the advantages of the automatic ventilation mode, we note the chance to create the necessary climate regime for certain plants.
Let us consider in detail the algorithm for creating automatic ventilation of a structure.
Electric ventilation
This is the most budget-friendly ventilation option. If you decide to make such ventilation in the greenhouse yourself, you will need an electric fan and a thermostat. It is the thermal relay that will become the main element of the circuit.
It allows the summer resident to adjust the function of setting the ventilation system to a given temperature regime, and to send a signal to the fan about the need to start working. Immediately after receiving the signal, the fan begins to function, cooling the air inside the greenhouse.
What are the main advantages of such a cooling system?
Advice! To increase the efficiency of such a ventilation system, you can install a window at opposite ends of the greenhouse that opens when the fan is running. Unfortunately, alternative energy sources (sunlight, wind energy) are not enough for the uninterrupted operation of the system.
Methods of ventilation in greenhouses
The disadvantage of the system is the difficulty of supplying uninterrupted power in the event of a power outage and the need to use expensive additional equipment. This is relevant during the hot summer season. When the ventilation system is turned off for 2-3 hours, the risk of plant death increases.
Advice! To partially solve this problem, you can use solar collectors fixed on the roof of the greenhouse.
Hydraulic ventilation
It is this method that can be considered a brilliant invention of our time. The hydraulic option for ventilation of greenhouses is considered the most durable and reliable system. Such a system includes the following elements: levers connected to each other by a transom.
The essence of the arrangement and functioning of such a scheme:
Disadvantages of hydraulic ventilation
Advantages of hydraulic ventilation
Advice! When choosing a hydraulic opener, it is important to take into account the opening angle; it is selected individually for each system. You can use machine oil for this method.
Biometric ventilation
This method of arranging automatic ventilation involves increasing the material if the temperature rises.
For the base, two metals are used that have different expansion coefficients and different quality characteristics. The operation occurs as follows: during strong heating, one plate bends, as a result of which the window is pushed out. As the temperature drops, the plate gradually cools and the window closes.
Positive features of this method of ventilation
Cons of the system
If the metal does not warm up enough, the plate will not be able to open the window, and ventilation will be impossible. There are plants that die when overheated; such a ventilation system is not suitable for them.
Types of windows
A polycarbonate greenhouse perfectly dissipates the sun's rays, prevents air from overheating in the building, has a long service life, and excellent performance characteristics.
Currently, two types of windows are used in polycarbonate greenhouses: classic and in the form of blinds.
The louvered version has a complex design and gives the maximum effect - guaranteeing the flow of air into the greenhouse, preventing drafts.
With a natural ventilation system, you will have to take into account the direction of the wind, monitor the air temperature, which requires a huge amount of time. Such problems will be completely solved by installing an automatic ventilation system.
Do-it-yourself automatic ventilation of the greenhouse
As always, craftsmen will definitely come up with the simplest and most affordable way to ventilate a greenhouse. Using fishing line or twine, the window is attached to a structure of two vessels with water, which are located at different heights.
The vessels are connected to each other by a thin hose. When the air in the greenhouse heats up, the water in the vessels also heats up. Expanding, it flows from one jar to another, and the window opens due to the weight of the lower jar of water.
When the air cools, the water returns and the window closes
This is how it’s easy to adapt two cans to ventilate a greenhouse in the absence of the owners
Conclusion
When creating the desired microclimate in a polycarbonate building with the help of ventilation, it is important to take into account all the nuances: humidity, temperature, plant variety.
Preparations in the form of aerosols
Products whose manufacturers have chosen such a simple and convenient form of release for home use have gained particular popularity. But the simple principle of use does not eliminate toxicity, so you should still be careful with such substances. To protect yourself, it is recommended to use goggles, a mask or respirator, and gloves. And after treatment, carry out through ventilation until the odor is eliminated, but for at least 20 minutes.
You can highlight the following funds from this group
1. “Combat” is a drug based on imiprotrin and cyphenothrin. Causes poisoning, paralysis, and then death of insects. It has a pleasant smell, which makes working with it much easier. The spray can comes with a nozzle for irrigation of hard-to-reach places. Exposure of the product is 30 minutes, after which it is necessary to carry out wet cleaning and ventilation of the room. The cost is approximately 400-500 rubles.
2. “Dichlorvos” is a drug that has saved us from insect invasion for decades, but has not lost its relevance to this day. Modern manufacturers offer various aerosol options - “Dichlorvos Eco”, “Dichlorvos Neo”. Each variation has some special properties, for example, the absence of an unpleasant odor or the presence of a fragrance that could mask it. The active ingredients are tetramethrin and cypermethrin. They have a strong effect on the central nervous system of bedbugs, causing their death. The advantages of this drug are its low cost (within 100 rubles) and prolonged action.
3. “Klopomor” is a drug against bedbugs with a strong effect due to 3 active ingredients. The product contains the following insecticides: piperonyl butoxide, permethrin and cypermethrin. But due to such a strong composition, there is a high risk of poisoning. The effect of the drug after irrigation can last up to 30 days. Its cost is 400-600 rubles, depending on the volume of the can.
4. “Raptor” is a product containing tetramethrin and cypermethrin, widely known due to advertising. It should be noted that consumers fell in love with this product due to its high efficiency and cost-effectiveness in use. Approximate cost: 250-300 rubles.
In addition to the funds listed, you can find others. Many manufacturers produce aerosol versions of insecticides due to the fact that this form is in great demand on the market.
But, unfortunately, it cannot be said that such cans will be comparable in effectiveness to cold fog treatment. They are only suitable for small pest infestations and are unlikely to cope with an infestation of bedbugs or other insects. In such cases, it is necessary to contact a professional pest control service.
Operating principle of cold fog generators
It is known that cold fog is considered the best choice for disinfecting premises. The device for its production is called an ULV generator or ULV generator. It is equipped with a special rotary compressor that supplies a huge amount of air under low pressure simply to the nozzles. There, the air flow separates the solution into small particles.
The nozzles of equipment that generates cold mist may differ in design. Some devices have a vortex generator, which consists of a pair of chambers. The first ensures the separation of the solution into particles with a diameter of 40 microns, while the second divides each drop into 8 particles with a diameter of no more than 20 microns. This allows you to get high-quality and very thick fog from bedbugs and other insects with the highest penetrating ability.
An electric ULV generator is considered the best option, especially when it comes to fire safety. It does not pollute the area as a result of fuel combustion, and also has a low noise level compared to other generators. Therefore, the use of cold fog against bedbugs and other insects indoors is considered the most rational. The devices' dependence on a good power supply slightly limits their use in open areas. A significant disadvantage of ULV generators is considered to be lower productivity compared to powerful models for generating hot steam.

Treating an apartment against bedbugs with cold fog
Precautionary measures before treating premises with cold fog against bedbugs consist of the following:
- It is necessary to first move the furniture away from the walls and remove dust there using a damp method;
- It is advisable to remove all carpets and paintings from the walls;
- It is best to remove food and hygiene products from the apartment or securely pack them;
- Place the dishes in sealed bags - after processing the housing, rinse the dishes in warm running water;
- Move all plants and pets to another place (you can agree with your neighbors);
- After treating the premises, it is necessary to treat chair seats, tables, furniture surfaces (especially fabric ones), door handles and nearby surfaces with warm soapy water.
The procedure for killing bedbugs with cold fog in most cases turns out to be more effective compared to other methods.
Cold fog generators against bedbugs are small-sized and produce steam (room temperature) with a small particle size (50 - 80 microns). Due to this, very effective destruction of insects with cold fog is achieved.
The chemical is sprayed in the room evenly throughout the entire space; this method allows you to efficiently and quickly spray cold fog against bedbugs over the entire area of the home. After the procedure, a pestilence of parasitic insects begins; after the cold fog, bedbugs begin to die intensively, simultaneously infecting their relatives, who may be located in hard-to-reach places.
Advantages and disadvantages of the cold fog method
For a number of reasons, this technology cannot be used in some rooms:
- school and preschool institutions;
- medical centers;
- residential areas (dangerous for allergy sufferers and asthmatics/people with other pulmonary diseases).
Advantages
- During processing, chemical particles remain in the air for a long time and at the same time gradually and evenly settle over the entire surface;
- Minimum insecticide consumption;
- Deposition and penetration of substances even into rather hard-to-reach places;
- High level of safety of the substance for human health and livestock.
Flaws
The disadvantages of this treatment method include the following factors: the absence of people and animals, as well as products from the disinfestation zone, the treatment is best carried out in the warm season, it is undesirable to wash the floors for two to three weeks in the treated room.
After 4 - 5 hours, the room must be thoroughly ventilated for 1 - 2 hours. If any of the residents will be present when the chemical is sprayed, they must wear a protective suit and a mask to protect their breathing.
Working principle of a cold fog generator
The cold fog generator operates on the principle of aerosol spraying and consists of an electric motor that drives a compressor (similar to a carburetor). During operation, the compressor creates a vacuum in the channel, which is connected to the liquid reservoir, thereby creating a dispersed state of the substance. The size of suspended particles is 30-80 microns.
