At what temperature do fleas die?

What fleas fear and dislike

Water is a flea repellent. Therefore, wet cleaning with repellents added to the water and washing pets help get rid of fleas. They cannot tolerate extreme increases and decreases in air temperature. They are afraid of strong odors of artificial and natural products. These can be: pine needles, wormwood, rosemary, soap. To combat fleas, the following are also used: salt, soda, boric acid, baby soap, onions.

Chemical smells

When figuring out what smell fleas don’t like, the obvious fact is the strong deterrent effect of artificial substances. These include the following available tools:

Bleach and whiteness

Products containing chlorine are very effective in fighting fleas. But when processing, safety precautions are required. Chlorine is a poisonous substance.

Attention! When inhaling vapors, very serious consequences occur. Processing of premises must be carried out using a respirator. The skin must be protected by protective clothing. After treatment, the room must be left for several hours.

Kerosene

Kerosene has been used as a deterrent since ancient times, despite the fact that it has an unpleasant, persistent and strong odor. This product has such disadvantages as persistent odor and flammability. To treat animals, it must be diluted with water.

Insecticides

Chemical insecticides are an effective way to kill fleas. The most effective insecticides are Karbofos, Doctor Klaus, Dichlorvos. They are designed for treating indoor and garden areas. The products are toxic and are not used to remove insects from animal fur. Such preparations as Butox 50, Raptor, Clean House, Raid, Combat are effective in destroying blood-sucking insects. The products are available in the form of sprays, aerosols and liquids.

Spray Raptor

Insecticides

They contain various aromatic additives that repel pests. Most insecticidal preparations act so quickly that they do not even have time to leave the threshold of the house. Even though animals can cope with their own blood-sucking insects, they need help in this fight. In addition, you should know that parasites cannot stay in wool for a long time, so they easily fill carpets, cracks, and spaces behind and under baseboards.

So, choose an insecticide:

1. Dichlorvos, Karbofos and other aerosols. When using them, you need to choose a time so that there is no one in the house: household members, pets. It is advisable to take indoor plants to the balcony or outside if possible, otherwise they will wither;
2. Pyrethrins and pyrethroids. These substances are present in these products: Raptor, Insecticide, Fas. Also present in collars and drops for treating the withers of pets;
3. Sprays. Industrial insecticidal preparations containing caustic substances. This is the smell that repels fleas from humans . They will not stay in the apartment for a minute. You can give preference to one of these: “Raid”, “Clean House”, “Butox 50”.

In addition to basic measures to combat these pests, it is necessary to regularly inspect animal fur for the presence of fleas. It’s even better to bathe them with special shampoos, put on collars, and apply drops to the withers.

Natural flavors

Most natural odors only have a deterrent effect. The use of fragrant plants and products does not destroy pests, but many aromas can become an obstacle to the path of fleas into the apartment. Brooms made from fragrant herbs, fumigators with essential oils, concentrated infusions and decoctions of strongly odorous plants are a pleasant and harmless way to combat parasites.

Tar

All these natural smells repel parasites. City dwellers can place herbs in all corners of the apartment, or purchase essential oil based on one of the above plants.

What plants repel parasites

Natural herbal remedies have proven effective in repelling fleas. Herbs must be used for a long time (The most effective herbs for killing fleas in an apartment). Fresh raw materials should be constantly added. Plants are placed around the entire perimeter of the rooms. It should be borne in mind that freshly harvested plants have a stronger effect than dried herbs. Fleas cannot tolerate the smell of the following plants:

• Sagebrush.
• Tansy.

Advice! We recommend constantly tying a sprig of a fragrant plant to your cat or dog’s collar. The esters contained in herbs prevent the establishment of pests. In the fight against blood-sucking insects, a powder made from dried bark grass gives a good effect.

How does heat affect fleas?

Blood-sucking insects are equally afraid of both cold and heat . At what temperature do fleas die - interesting information. So animal fleas and bed parasites begin to die at 47°C. Of course, such a high temperature is unlikely to occur in any apartment or private house, but now insects are destroyed using special thermal units. Bed fleas are removed by boiling linen.

Steam generator against fleas

Modern installation is used in cleaning clothes, upholstery and so on. The generator operates by heating water with a heating element, which is converted into steam. The steam is directed to those places where the largest concentration of parasites, larvae and eggs is found. It is necessary to act for several minutes, waiting for the insects to begin to die. The power of the steam apparatus is important; the greater it is, the greater the effect. Fleas die at temperatures critical for their existence. The room must be treated according to the following rules:

• the temperature should be from +50 degrees;
• start the operation after washing the animals;
• scald all clothes and surfaces in the house;
• Do not direct steam jets at paintwork.

The best steam generators are those used by sanitary services.

Drugs that cause paralysis in insects

There are a number of drugs that penetrate the chitinous membrane of pests. After the active substances enter the insect’s body, its nervous system is damaged. One of the effective drugs with a paralyzing effect is Tsifoks.

The drug is available in the form of a clear liquid with a pungent odor. Cypermethrin is the main active ingredient. The insecticide is economical: a liter container is enough to treat a large apartment several times.

Attention! The product is very toxic! Used for treating premises and summer cottages. The insecticide is available in glass bottles of 50, 500 and 1000 milliliters.

Another option for killing fleas is Sinuzan spray. A powerful professional product used by exterminators. Users note the rapid destruction of fleas - within one hour. The drug copes with adults, their eggs and larvae. Using the product requires strict compliance with safety measures. After treatment, leave the room for several days.

Environmental conditions

It is known that fleas are afraid of strong smells. It terrifies their nervous system, causing paralysis of individual parts. Because of this, fleas cannot move and then die. When the concentration of insecticide is strong, death occurs very quickly, within a few tens of seconds. If an insect hears an odor that is unacceptable to it, it does not jump onto the victim from which it comes.

Are fleas afraid of water?

Fleas are not afraid of ordinary water (without a special smell). They are afraid of water, which leads to suffocation. When the owner washes his pet with water in a basin, even without using a special shampoo, the bloodsucking animals die in the water. And treating rooms with water (frequently washing floors, spraying corners with water) will not lead to successful results. Water flavored with an unpleasant odor for fleas will repel or paralyze parasites.

Earth fleas react sharply to changes in environmental temperature, especially towards cold. At low temperatures (from -10 degrees), females stop laying eggs, and new fleas do not emerge from the cocoons. Cold with a temperature of -15 degrees. becomes critical for the “flea horde.” Insects try to leave such premises.

Tar soap with a special smell is not liked by bloodsuckers in any form. Floors washed with it repel parasites. True, people don’t really like this smell either. A dog or cat washed with tar soap will remain for some time without parasites, their larvae, and eggs. In this case, you need to wash the bedding where the pet sleeps with water and tar soap or bleach. To completely get rid of parasites, the procedure of bathing with a strong-smelling cosmetic product must be repeated.

Fleas cannot tolerate certain conditions, the creation of which can lead to their disappearance. Like other insects, bloodsuckers are afraid of negative temperatures. Even a drop in air temperature to 10 degrees does not allow the “horses” to reproduce. This fear makes it possible to quickly defeat fleas in winter - you just need to let the frost get into the room. And if doing this with an apartment is somewhat difficult, then freezing a barn, a chicken coop or a separate summer kitchen is not at all difficult.

Fleas, their eggs and larvae

Fleas are afraid of water, so while bathing the animal, you can reduce the number of insects. To do this, you need to pour enough water into the bath so that the animal is completely covered. You can water your head from a ladle, avoiding getting water into your ears. The fleas will move to the remaining dry areas where they can be easily collected. The sun also repels fleas - bloodsuckers try to run away from an animal lying in the sun.

What fleas are not afraid of

Important! Contrary to various rumors and myths, you should not believe advertising that convinces buyers of the effectiveness of certain electrical appliances. For example, no benefit from ultrasound machines has been proven. The electromagnetic waves generated by the devices do not repel insects.

Preventing the appearance of fleas in the apartment

For preventative purposes, rooms should be thoroughly cleaned at all times. Inspection and treatment of pets with anti-flea drugs should be carried out regularly.

Fleas often enter living spaces from basements. Treating basements with chemicals is a mandatory preventative measure. Fleas can get into an apartment in different ways: on clothes, shoes, on an animal, from neighbors.

Attention! If single individuals appear, emergency measures should be taken to destroy them. Fleas reproduce quickly. Losing time threatens to increase the population exponentially. 15 of the best folk remedies for fighting fleas.

What are fleas afraid of at home?

Exhausted by the constant discomfort of being in close proximity to colonies of bloodsuckers, the inhabitants of houses and apartments sometimes do not always realize that fleas are just insects that have their own fears. For example, they are afraid of various pungent odors, such as bleach, water, cold, severe frosts, some herbs and much more. It is this knowledge that helps to successfully scare away uninvited guests and prevents them from staying inside residential premises for a long time.

Are fleas afraid of water?

It should be borne in mind that fleas die under water. So, if you periodically bathe an infected pet, it can be rid of some of the basement or earthen insects and significantly alleviate suffering. But at the same time, damp places in the room do not cause any particular inconvenience to parasites. On the contrary, the larvae prefer to live in places where animals defecate (their toilets), where they find food for development and vital activity.

As for bird fleas, for example goose fleas, they, together with their carrier, dive under water for food and this does not bother them at all.

These individuals cannot be frightened either by standard wet cleaning or by pouring water on corners with baseboards. It’s another matter if you add one of the folk remedies, for example, based on herbs, to this water. This will be discussed further.

Are earth fleas afraid of frost?

Already at ambient temperatures below +15°C, bloodsuckers stop eating; when 0°C approaches, they die. Only their pupae can survive frosts and extreme cold.

Therefore, one of the methods for destroying fleas is freezing them. In winter, when there is severe frost, it is recommended to take upholstered furniture out into the open air for several hours. Also open all windows inside the house or apartment, letting in the cold. After a while, at such a low temperature, eggs with larvae and adults die.

For the purpose of prevention, re-freezing is recommended after one week.

Are fleas afraid of tar soap?

Tar soap has medicinal and insecticidal properties, which is why various insects do not like it so much:

Birch tar is toxic to parasites; the benzene in its composition has an extremely negative effect on their nerve centers. Phenol and its derivatives provoke chemical burns in parasites.

Thanks to this, tar soap has proven itself in the treatment and prevention of fleas in cats and dogs. In addition, it helps to improve the general condition of damaged skin, relieves itching after bites, and heals wounds.

Reviews from people

Alexey, Saratov:

I don’t understand how fleas got into my house? I don’t like chemistry, I try to do without it. After reading your article, I decided to kill the parasites with cold, it’s just winter. I pulled out everything I could. I can't see it yet, I'll wait some more. If it doesn't help, I'll try another method.

Milana, Ekaterinburg:

“I have never encountered such a problem before. I saw it on a cat a couple of times and immediately bought a collar. And then the whole family was attacked! I poisoned him with everything possible. I poured out a whole bottle of dichlorvos. They disappeared for a while, then they came again . I even read it at what temperature do fleas die in an apartment . I had to call the sanitation service. There are inconveniences, of course, but not a single flea remains. It turned out that they were climbing from the basement on the first floor. They were killed there too.

How to kill flea larvae

Flea larvae are very similar and sometimes it is difficult to determine which type of parasite they belong to. In the fight against them, means are used that are used to exterminate adult fleas, and at what temperature fleas die can be found on the Internet. Some remedies are powerless. For example, wormwood will scare off imagoes faster, but will not affect the larva. There are means to guarantee the death of bloodsuckers:

1. Microcapsule preparations of the Get type, which are odorless, which distinguishes them from other substances.
2. Concentrated liquids that require dilution with water. These are drugs such as: Tetrix, Cucaracha, Karbofos. But they are toxic with a chemical smell.
3. Sprays are ready-to-use and easy to use. For example, Raptor, Combat with a nozzle for processing cracks and baseboards, penetrating into the farthest cracks, behind baseboards. Their action is spot-on and not so long-lasting because they evaporate.
4. The powders Clean House and Pyrethrum are natural and work well against parasites. There is one drawback - there is no contact with larvae in hard-to-reach areas.
5. Traditional methods include treatment with kerosene, vinegar and turpentine. Spruce shavings repel bloodsuckers. They are afraid of the smell and do not lay eggs. Sawdust is also used to stuff pet beds.

The larvae only seem harmless. But after some time, dangerous parasites harmful to humans will emerge from them.

What temperature is lethal for flea eggs

Knowing at what temperature in the room parasite eggs die, you can completely get rid of insects in the house. The larva resembles a small white worm. Under a microscope, the head and esophagus are visible, where food debris is visualized.

The size of the eggs is 5 mm; they are laid in booths and bedding located next to the pet. There are no larvae on the animal’s body; to lay a clutch, the adult leaves the victim and then returns.

When getting rid of parasites, take into account that it is necessary to treat the pet’s fur and its sleeping place . Boiling water and washing in hot water instantly kill the larvae. Sunbeds need to be washed and steamed.

Almost any flea remedy that is used in practice fights against adult fleas and has no effect on the larvae.

To eliminate immature parasites, drastic measures are required - freezing, using high temperatures. The sunbeds are taken out into the sun or frost and washed in hot water.

Temperatures of +45 C° and -15 C° are detrimental to the larvae. In such conditions, the eggs should remain in the cold for 3-4 hours. In the heat, the shell is destroyed, the immature individual cannot continue development. It is best to use a steam generator, but the method is expensive.

How to choose the optimal temperature to kill fleas

To get rid of blood-sucking insects, sometimes it is enough to create unfavorable conditions for their life and reproduction. What parasites can’t stand, with what plus and minus do fleas die:

1. High temperatures and dryness. To get rid of fleas, you can simply fry them. There are a huge number of options to do this. Bed linen and animal bedding can simply be boiled down. Pour boiling water over those surfaces that will not be damaged by this. In hot weather, carpets, rugs, bedspreads and curtains should be hung in the sun and left there for several days. You can also use a hair dryer or steam generator.
2. Cold. It is unlikely that you will be able to freeze the entire apartment, because this may damage the plaster, paint and wallpaper. But individual elements of the interior and household items are fine. But at what negative temperature do fleas, larvae and nits die? It is enough to take the contaminated items outside in frost conditions of -15 for 5-6 hours. This method will help get rid of parasites in sheds, garages and chicken coops. To do this, the room is left open for 2-3 days.
3. Water. To do this, the contaminated item, if this does not spoil it, is completely immersed in water for a while. Although bathing animals does not eliminate all fleas, it does help reduce the number of parasites.

During very hot and very cold weather, try to remove household items that are susceptible to flea infestations outside. Let sunlight into your apartment more often and do general cleaning.
