So that when fighting bugs, no matter how prolonged it may seem, your hands do not drop, you need to clearly understand: bed bugs are just insects-parasites, and they have their weaknesses. They are vulnerable. Even if we do not take into account the powerful insecticides and supernovae developed by scientists aimed at the rapid destruction of these parasites, we can immediately bring up a list of what bugs are afraid of, and then choose from this list those tools that could be most effectively used in the fight against these bloodsuckers in ordinary household conditions.
It should be understood that even if bed bugs are afraid of this or that substance or factor, this does not mean that they will die from the same substance. Typically, such scaring agents are rationally used to stretch a few days before pickling the room or to prevent the penetration of parasites into the house.
Too high and too low temperatures
The optimum temperature regime for the life, nutrition and reproduction of bedbugs is from 20 ° C to 30 ° C. Temperatures ranging from 10 ° C to 20 ° C and from 30 ° C to 35 ° C are already uncomfortable, but tolerable for parasites. They do not try to avoid places with such a climate, but practically can not reproduce normally under these conditions.
But constantly operating temperatures below 10 ° C and above 35 ° C cause the parasites to look for new habitats. Although if the temperature regime changes during the day, they can "accept" this.
It is interesting
Very large natural populations of bed bugs were found in the deep caves of Turkmenistan and Tajikistan. Here, insects parasitize on bats. The temperature in such caves almost never rises above 15-16 ° C, but the bloodsuckers seem to be quite happy with it.
Conclusion: to force habitual parasites to escape from home, it must either be cooled for a long time below 10 ° C, or warmed to a constant 38-39 ° C.
Bed bugs are afraid of light. These are strictly nocturnal insects, peak activity of which falls on 3-7 hours in the morning. A light in the room or a raised mattress makes them panic.
True, it is difficult to use this fear of insects in practice: if they find a reliable dark place behind the skirting boards, it will be very difficult to scare them with light.
"When we called the Sanitary and Epidemiological Station, we asked the children if the bedbugs of light were afraid. They told us that the bugs are generally afraid of being in the light, and finding an insect in the day is very difficult. Then the guys began to pick up mattresses and carpets and I was horrified: there were thousands of bedbugs and larvae, so small and disgusting! They all fled from the world quickly ... "
Smells of wormwood and tansy
The main folk recipes for scaring away bloody bloodsuckers are based on the fact that bedbugs do not like the smell of wormwood, tansy and some other plants.
Wormwood is the most famous herb from bedbugs. To control the parasites usually lay out the brooms of their dry plants under the beds and other furniture. For at least a few days, such measures produce results.
However, the bedbugs are afraid of wormwood only until they are very hungry: it's literally on the third or fourth day, even fresh branches of grass will not keep them from attacking.
It is interesting
In search of food and building their picture of the world, bed bugs use mainly smell. Sight and hearing for them are less important, and because strong odors frighten these parasites better than sounds and light.
With tansy the situation is similar.
As a rule, it is most reasonable to use these herbs not to discourage insects, but to create aromatic barriers for their penetration into the room: dry branches are placed in ventilation boxes and on balconies near windows. Accidental "vagrants" from neighboring apartments, having met such an obstacle, are likely to unfold.
"We generally got bedbugs after the holiday. I do not know where they came from, but the first night after their return they got us stuck. And in all the rooms, and me and my husband, and children. We summoned the pest control centers, but they could only arrive on a working day, and we had to endure for three days. We guys were advised to use some kind of folk remedy for these days. I went to the bazaar, I asked the traumatologist, what grass bugs are afraid of. They said that tansy and wormwood. I bought that tansy, put it under the beds - and really, these mucks did not touch us for three nights. As the guys from the fighting service said later, this is the deadline - then the grass ceases to function. And it's good that the bedbugs were not wound up in bed, but were sitting mostly behind the carpet on the wall. But just on the fourth day they were all put to death. "
Traditionally, birch branches are also used in villages against bed bugs. However, there is no serious evidence that such a tool helps.
Since the Middle Ages it is known that bedbugs are afraid of fragrances of perfumery. Noble princes and court ladies in France, Italy and the United Kingdom used to take aromatic baths before going to bed, and then literally poured perfume and cologne from head to foot to protect themselves from bloodsuckers.
Indeed, bedbugs do not like pronounced fragrances of perfumes, regardless of their quality. And the sharper the smell, the more unpleasant it is for parasites.
Nevertheless, insects can quite overcome their dislike with a strong hunger, and after two or three days the hunger strikes will be quite actively biting a scented sleeping man.
Chemistry: kerosene, denatured, turpentine, acetone, vinegar
But among these funds there are really reliable repellents (the so-called means that repel insects).
For example, bed bugs are afraid of the smell of ammonia. And than this smell is more distinct, the less attractive will be the room for insects. Therefore, in order to prevent the penetration of parasites into the house, ammonia should be added to a bucket of water when washing the floors. Indicator of reliability here will be the sense of smell of the person: if after cleaning the smell of ammonia is felt in the apartment, the bugs here will definitely not be comfortable.
So do not like bedbugs and the following smells:
- methylated spirit
None of these substances kill the parasites directly with their odor. But repellents of them turn out to be excellent with the same use as for sodium hydroxide.
For example, even after dipping into vinegar (table, 9%), the insect will remain alive. But usually bedbugs do not tolerate the smell of any vinegar, and if at least one drop of it is put in the center of a parasite spot, they will not appear in this nest within the next few weeks.
"My grandfather taught me to bug turpentine bugs, so I used all that youth and used it. In the army, the barracks was cleaned with him, he already made a day off. Then he took them to the school in the hostel with the same turpentine. Just take it undiluted and squirt under the bed and in all corners. I even wanted to sprinkle it in my new apartment, but my wife said that she would leave me if I did it. I had to buy some newfangled substance in the can. It's also an effective piece, but expensive compared to turpentine. "
The minus of all these means is that for a person their smells create no less intolerable conditions, and to live in such a room protected from bedbugs is also extremely difficult.
Debunking myths: what bugs are not afraid of
In contrast to really terrifying for bedbug remedies, there are also things that in the general masses are thought to scare off bedbugs , but to which the parasites actually treat with complete indifference.
- ultrasound - as shown by special studies, high frequency sounds have no effect on the behavior of bedbugs
- water with salt or soda, which folk craftsmen advise to do a wet cleaning, does not frighten parasites at all
- magnetic resonance field. It was for him to switch creators of ultrasonic radiators, when more and more users began to make sure of the uselessness of the latter. The magnetic field affects bedbugs the same way as humans: to use the radiator to drive them out of the house, you need such a powerful radiation that a person can not withstand.
And of course, completely conspicuous in the fight against bed bugs will be various conspiracies, prayers, hints and jokes, which are still used in especially deep provinces. As long as they try to fight with parasites in such meaningless ways, they will thrive and delight the person with their neighborhood and unlimited appetite.
Fight with insects correctly!
