How effective is the destruction of bedbugs with hot fog?

The destruction of bedbugs with hot fog consists in heating the insecticidal mixture to a temperature above 50 ° C and spraying it into the infected object. Due to the sufficiently high temperature, the toxic substance does not settle on surfaces for a long time and spreads throughout the space of the room.

A suspension of the active substance is formed in the air, penetrating into all cracks and niches inaccessible to humans, in which bedbugs can hide. As the aerosol cools, it settles on surfaces with which the parasites can come into contact, and on the insects themselves, leading to their poisoning.

Treatment of bedbugs with hot fog is also effective because the parasites themselves do not tolerate temperatures above 45ºС. A hot spray kills them on its own, but an insecticide works when the fog cools after mixing with air. Thus, with the right approach, the destruction of bedbugs with hot fog is more effective than simply spraying household sprays and aerosols or using a similar method - cold fog.

Review

“Just a huge thank you to the guys who helped us cope with the abundance of bedbugs in the new apartment. We were immediately told: if we want to get a good effect and quickly, choose the hot fog method. The apartment "kopeck piece" was processed for about 1 hour. Then, until the evening (4-5 hours), they waited until it all settled, then aired it. In general, they went to bed only late at night, but without bedbugs.

Elena Arkadievna, Tver

Hot fog can be used to kill bedbugs in almost all types of premises potentially suitable for the habitat of these blood-sucking insects. However, it should be noted that this method is associated with certain difficulties in bringing apartments, houses, baths or hotels into a livable and safe condition after baiting bugs, so the instructions of the exterminator should not be neglected during subsequent cleaning.

 

Advantages and disadvantages of hot fog

The main advantage of hot fog, as noted above, lies precisely in the high temperature of the aerosol: when processing nests and shelters of bedbugs, insects and their eggs die almost immediately from heating. Given that the generators used by professionals provide heating of the insecticide to 80-90ºС, the destruction of bedbugs by fog during direct processing is very fast.

Review

“I remember that there was a lot of smoke and I had to wait quite a long time for everything to disappear and it would be possible to move into the apartment. But the result seems to be good. A month passed - until not a single bug wanted to return. There is only one drawback, in my opinion: it will be expensive. If there are not many bedbugs, then it will probably be cheaper to do with conventional processing methods.

Sergey, St. Petersburg

In addition, due to the high temperature, the fog hangs in the air for quite a long time, and then settles evenly on the surfaces. Such a prolonged effect on parasites has its advantages: thanks to this, it becomes possible to destroy even those bugs that did not die for some reason in the first hours after treatment.

However, this method also has its drawbacks:

• In most cases, it is problematic to use hot fog to kill bedbugs on your own, since the fog generator is expensive and it is not rational to buy it for the sake of one treatment.
• The processing time of the room when using hot fog is stretched. According to the rules, the insecticide cloud should hang in the air for at least 3-6 hours, and after the drug settles, you need to wait at least another 2-3 hours. Thus, the treatment of the room from bedbugs with hot fog drags on for almost the whole day.

And most importantly: the destruction of bedbugs with hot fog can be dangerous for the handler himself, and therefore requires strict adherence to the operating instructions for the fog generator and the availability of personal protective equipment. When compared to using household sprays, this method appears to be more risky for untrained handlers.

Review

“As I understand it, the main advantage of hot fog treatment is its high penetrating ability, so there is no need to purposefully look for places with the greatest accumulation of parasites. Small droplets of steam penetrate into all the cracks and even penetrate the structure of fleecy materials. Therefore, processing by this method seemed faster to me. The whole apartment (3 rooms) was processed in an hour and a half. The result is still holding up."

Destruction of bedbugs with hot fog generators

The procedure for the destruction of bedbugs with hot fog is divided into three stages.

1. Preparing the room for processing. It should be borne in mind that the aerosol should settle freely on the baseboards, in all corners of the room, on the back surfaces of the furniture. Particular attention should be paid to beds and sofas, in which bedbugs most often hide during the day. When preparing the room, you need to move furniture away from the walls, roll up carpets, remove bedding and mattresses, close windows and doors. All people and pets must leave the treated area.
2. Actually processing.Despite the ability of fog to penetrate into hard-to-reach places, door frames, beds and sofas, baseboards are especially carefully treated with a generator, and the aerosol is additionally distributed throughout the space in the room. After that, the room is closed and kept for 6-7 hours.
3. After the expiration of the settling time of the insecticide in the apartment (or any other room), a general wet cleaning is carried out, during which all surfaces are thoroughly washed, if possible.

If the treatment is carried out by the disinfestation service, the owners of the premises take part in this process only at the stage of preparation for the destruction of bedbugs, and after that they put things in order. It is worth noting that today some services offer, for an additional fee, their employees to prepare the premises for processing, and then clean it up.

If the processing will be carried out by the residents themselves, then they should familiarize themselves with the features of this process in advance, read the reviews and, of course, worry about the means of protection and safety of the processor.

 

Safety Rules for Using Hot Fog Generators

So, you decided on the independent destruction of pests with hot fog. First of all, you should protect your body and respiratory organs from contact with poisonous aerosol. To do this, you will need: a respirator (gauze bandage is not suitable here), long-sleeved clothing, glasses, a hat and gloves on your hands.

And one more thing: the bugs hid in all the cracks, and you just can’t find their nest? And smoke bombs find bedbugs where even a needle cannot squeeze through ...

As mentioned earlier, there should be no animals in the processed room. If there is an aquarium, it should be tightly closed with a coverslip, turn off the compressor, and put a wet sheet or a large towel on top.

One of the most important safety precautions during processing is careful monitoring of your well-being. If you suddenly feel a burning sensation on the skin, headache or nausea, the destruction of bedbugs should be stopped immediately, go out into the fresh air, and rinse the irritated areas of the body with clean water. If after this the symptoms do not go away or get worse, you should immediately go to the hospital.

Review

“They did the treatment for bedbugs with hot fog. I don’t know what kind of compounds they used there, but I think it’s irrational and expensive. Of course, there is a result, but we got about the same effect two times cheaper when processing a smaller area. Moreover, acquaintances complained that, after hot fogging, the bugs did not completely disappear, and after two months they had to repeat everything.

Review

“After living in the apartment of representatives of southern nationalities, they discovered a lot of “interesting” things there. The worst thing was the abundance of bedbugs and cockroaches. At first, the brother tried to cope on his own, but a month later they decided to call the SES, especially since the neighbors also began to complain about the unpleasant neighborhood. They dragged a kind of “vacuum cleaner” into our apartment, pumped all the rooms with hot smoke and left after about an hour. I had to wait a long time for all this to settle and disappear, so we spent the night with friends, but the result is excellent.”

Olesya, Moscow

Compared to cold fog generators, hot fog generators are quite expensive, there are practically no household models among them. Hot mist generators belong to the category of professional equipment, and therefore have a higher efficiency, which, in turn, ensures their continued popularity among pest control workers.
