Do mice gnaw polyurethane foam what do the owners say

How and the earlier they insulated the house so that mice would not start in it

Today on sale there are different types of modern heaters, which have never been heard of before. The old proven methods of thermal insulation are the use of expanded clay, slag and ordinary sawdust mixed with quicklime (fluff). Rodents will never enter a house insulated with such materials. The use of foam, mineral wool or polystyrene foam will not protect the home from pests.

Conditionally secure the house will help ultrasonic repellers, poisonous baits and mousetraps.

The harmful effects of ultrasound are not felt by a person, but this does not mean that it does not affect him. The safety of such devices for humans has not been fully proven. Spreading poison is a danger to pets and children, and mousetraps are ineffective. Interestingly, rodents are afraid of the smell of wormwood, so you can add the leaves and stems of this plant to the insulation, only you need a lot of them.

Do mice gnaw on polyurethane foam? Does polyurethane foam save from mice? You need to close up a hole in the basement. do not gnaw 22 answers

In the Construction and Repair section, to the question, does polyurethane foam save from mice? I need to patch up a hole in the basement.

won't gnaw? given by the author Ni Ka the best answer is It will not help - they will gnaw through! Cement or you can buy a ready-made solution in a bucket, it does not steam, and pour it.

I did everything ok without glass! Sergey MatkovskyMaster(1017)

I don’t remember, in general it was not even cement, but a putty adit of white color. Well, in general, in a plastic jar of 5 kg, what was som not big.

Reply from 22 answersHi! Here is a selection of topics with answers to your question: does polyurethane foam save from mice? I need to patch up a hole in the basement. won't they gnaw through? Answer from Kolosok And that mice can't gnaw through foam? Or what are they afraid of? Yes, you can’t break them with anything. The answer from Karkusha will be gnawed ....

Answer from dampness They gnaw through, better with concrete with glass, then maybe they will break their teeth Answer from Max PlankoffRats gnaw concrete, and you foam?

Option: filling with foam, and glass or iron sheet on the problem side.

Answer from Name fProgryzutAnswer from MilaSaves only broken glass

But if your other walls are weak and mice can easily gnaw, then don’t even bother with broken glass in this one hole - the mice will gnaw through nearby.

Answer from Ivanov Ivanov It is better to fill with uranium-236 with diamonds! What the hell are you talking about. Mice will not gnaw foam, rats can if they need it, i.e. they will know that there is food behind the barrier, etc. But in general it’s better to concrete it, well, or close it up with gypsum at the very least. Answer from Igor I have a fan pipe from the inside gnawed through (gray plastic). They will pass your foam in 5 minutes. Try it with concrete. Answer from Vladimir Pykov There is a special composition, such as foam, mice and rats do not gnaw it, I forgot what it is called. immediately into the basement of a mousetrap, I was tormented with rats a couple of years ago - sheathed the walls of the plasterboard on an aluminum frame (and the racks were foamed for rigidity) and the large holes between the logs were also foamed) and as soon as it got colder - I heard a joyful crunch of foam! what an echo! in general, poisons and cats and everything in a row - there was no way to get it out, but I got out of the situation with a simple mousetrap-cracker (as in Tom and Jerry), the main thing is not to put cheese (it’s only in cartoons they love cheese) but ordinary raw meat. and every night I shot one rat, and so I caught six of them, and it seems like they haven’t bothered me for a couple of years.

Pests in the barn

Rodents try to get not only into the house, but also into any buildings in search of food.Therefore, residents of private homes are interested in how to get rid of rats in the barn on their own. In such a room, they either keep large quantities of food for livestock, or themselves. Therefore, for rodents there is always something to profit from.

Important! Their presence affects the health of birds, and as a result, productivity. Therefore, you need to get rid of impudent pests immediately.

Chemicals

The easiest and cheapest way: just buy a pesticide and pour it out at the point of penetration. However, everything is not so clear: pets can also be poisoned. It is unlikely that there will be an opportunity to transfer animals for 2-3 days from the treated area, so this approach is risky. However, you can prepare traps: for example, put poison in boxes where chickens, for example, will not climb.

There are several types of chemical poisons:

Apply force

Rats are larger and much more dangerous than mice, so it is advisable to know how to get rats out of the barn with folk remedies before they make trouble - these rodents strangle chicks with great pleasure. Placing traps near their holes and setting special traps is a sure and effective way to catch pests. You can have several cats that are able to hunt and kill rats: this ability does not depend on size at all. Fluffy mousetraps can be very tiny - everything is decided by speed and resourcefulness.

Folk ways

To get rid of rodents, you need to make their stay in the barn unpleasant. This is even more effective than direct destruction - rodents multiply quickly and do not stop in front of traps.

• Stove ash scattered on the floor guarantees digestive problems for mice;
• If no one lives in the barn, you can use naphthalene or kerosene - this is a sure way to get rid of rats and mice in the barn.
• Holes in the walls and then need to be covered with broken glass, and then poured with concrete. No mounting foam!
• Cruel way: a mixture of clay and flour will attract rodents, so water is placed nearby. The gypsum hardens from the liquid, the mouse dies.
• You can hang and spread bunches of herbs - black root, whose second name is a rat racer, is not felt by a person, but it is fatal for rodents.
• Tansy, wild rosemary and peppermint - any of these plants will help get rid of rats and mice in your area.

Rodents from year to year destroy crops and livestock, harm humans

Being careful and taking timely measures will help protect yourself and your home from rats and mice.

Protection of foam from pests

Styrofoam is a very convenient material for thermal insulation and sound insulation. But it is the various foams that are most susceptible to attack by mice and rats. These are materials such as extruded polystyrene foam, polyurethane foam, penoizol, penoplex. These materials are artificial, therefore they are not suitable for mice, but they gnaw them and turn them into dust. In the resulting voids, rodents arrange nests for themselves. To protect it from rodents, certain measures must be taken:

1. 1. It is necessary to choose foam for insulation of dense varieties, since it is inconvenient for mice to gnaw on dense material.
2. 2. Proper foam installation is required. It must be carefully puttied, as well as sheathed with the help of special materials, selected individually. The purpose of proper installation is to prevent the appearance of cracks, since rodents enter the dwelling through the cracks.
3. 3. All openings must be sealed with mounting foam.
4. 4. It is desirable to provide metal sheathing along all walls at the pest penetration level. They can't deal with metal.

These measures must be taken into account at the construction stage. If they were not accepted, it remains to take actions aimed at scaring away rodents:

1. 1. The easiest way is to get a cat. Only the smell of a cat in the house repels mice.
2. 2.You can install an electronic repeller, but if the area of ​​\u200b\u200bthe house is large, one device will not be enough, you will have to install several. Such repellers emit ultrasound of various frequencies, which cause fear in rodents and force them to leave the building.
3. 3. All food supplies must be kept out of the reach of rodents.
4. 4. The house must be kept clean.

To protect the foam, folk remedies are effective. They are based on the use of various plants that repel rodents with their smell. These are plants such as needles, tobacco, mint, wormwood. These plants in a dried form, it is enough just to scatter them in the corners. At the stage of building a house, you can process the foam with lime or red pepper.

Some people use boric acid to repel pests, but its effectiveness in controlling rodents has not been proven.

If none of the above methods helps, you need to contact the sanitary and epidemiological station, whose employees will come and carry out a complete disinfection of the premises and the elimination of all rodents.

How to protect the thermal insulation circuit from damage

If you get a house with a ready-made thermal insulation layer, or the population of mice began to increase suddenly, you need to take measures to protect the insulation. Otherwise, after a couple of years, heat losses will increase, and heating bills will increase with them.

There are several options that I would advise to implement in a complex way:

1. We protect all heat-insulating layers with a dense material, preferably one that will be too tough for a rodent.
2. In the cavity and the discovered passages, we fill in broken glass, wood shavings soaked in copper sulphate, or push in glass wool.
3. We store all food products and inoculum out of the reach of mice. There is no food - there is no incentive to nibble, and seriously settle down in insulated walls.
4. We lay out poison behind the skin and in the corners, install ultrasonic devices that repel rodents.

Well, and the most effective way, which, in addition to getting rid of rodents, has a bunch of other beneficial effects. Finally, get a normal cat, and every morning you will find several gray carcasses on the porch. Sooner or later, the mice will run out, and your insulation will be safe.

True, the cat will stay and ask for food, but it seems to me that this is a completely acceptable price for peace and order in the house.

Additional ways to protect against mice and rats

If the thermal insulation layer has already been installed, and the problem with rodents has appeared recently, additional protection measures must be taken.

It is important to exclude mice from access to the layer. This can be done without dismantling the insulation

To create additional protection, it is recommended to use the following methods:

Installation of steel mesh. It is installed in front of the heater. The method is expensive, but effective.
The use of chemical compounds - "Krysid", "Goliath", "Mortorat". Processing is done in accordance with the instructions

It is important that this does not change the properties of the insulation.
Use of alternative heat insulators. Rodents are afraid of sounds, so a layer of fallen leaves will scare them away.

Insulation that resists rodents

There are a number of signs that mice choose insulation materials: low density, lack of moisture, warmth, and the possibility of use as food. Therefore, to protect against rodents, these factors must be excluded.

Insulation that can withstand the attacks of rats and similar animals should have the following properties:

• High density. This is the main obstacle for rodents.
• Treatment with special means, the concentration of which is safe for human health.
• Loose structure of insulation. It does not allow pests to make nests in the material.

These requirements are met by a number of heat insulators, which need to be considered in more detail.

Foam glass

For the manufacture of foam glass, cullet is used, which goes through the stage of heat treatment. To create voids, foaming agents are added - anthracite, coke. In the future, the formed hollow granules can be used as bulk material. To make blocks, they are poured into molds and then subjected to pressure and re-treatment at high temperatures.

When choosing foam glass as a heater, you need to take into account its properties (see all the characteristics here):

• Large share. Depending on the manufacturing technology, the density of the material varies from 100 to 600 kg/m³. This is a high figure, which negatively affects the conditions of installation and processing.
• The thermal conductivity coefficient is one of the lowest among heaters - from 0.043 W / m * C. For bulk types of foam glass, it is higher, since the tight contact of the granules with each other is not ensured.
• Fire safety and soundproofing. They are due to the properties of the material of manufacture and its structure.
• High price. The average price for 1 m³ of block foam glass is 17,500 rubles.

This insulation is chosen if the problem of rodents is relevant and it is required to provide a high degree of protection against them.

Expanded clay

Expanded clay is made from special grades of clay using a technology similar to foam glass. But unlike it, the formed granules cannot be pressed into a single block, since they have low mechanical strength and elasticity. This insulation is not gnawed by mice and rats because of its flowability.

To analyze the relevance of the use of expanded clay, its characteristics are taken into account:

• The nominal thermal conductivity for one granule is from 0.01 W/m*S. But in fact, for a layer of expanded clay, it is higher, since "cold bridges" are formed between the components. It all depends on the density of the backfill.
• The compaction factor is 1.15.
• Fraction 10-20. It is this size of the granules that is used for insulation.
• Water absorption from 8 to 20%.
• The average cost is from 1300 r per 1 m³.

Expanded clay can only be used as loose insulation on horizontal surfaces.

Ecowool

It is made from waste from the paper industry. After processing, ecowool is treated with compounds of brown salt and boric acid. Their concentration is dangerous for rodents, but does not affect human health. To apply ecowool to the surface of walls or floors, special pneumatic equipment is used. The final drying time of the protective layer varies from 2 to 4 days, depending on its thickness.

The main characteristics of ecowool:

• Insulation belongs to the category of moderately combustible materials. When exposed to open flame, it does not melt, if the source of ignition is removed, attenuation is observed.
• Average density - up to 55 kg / m³.
• Thermal conductivity - up to 41 W / m * C.
• The price includes work on applying the material - from 600 rubles. For 1 m² with a thickness of 100 mm.

It is advisable to use ecowool for large volumes of insulation.

Bitterness from mice

In Europe, a few years ago, mounting foam was developed with an extremely unpleasant taste for mice. She is also avoided by other unpleasant guests: bedbugs, cockroaches and rats. In Russia, this miracle cannot be found, however, you can try to make some analogue yourself. Of course, it is much better to use the right and reliable materials right away, but situations are different.

Interesting! To protect the mounting foam, it is enough to sprinkle it with a special aerosol after hardening, the range of which is always extensive in hardware and construction stores. Such a simple protection system can work if moisture does not constantly get on the insulation, otherwise the whole effect will disappear very quickly, also spreading an unpleasant odor.

Why mice gnaw on inedible things, including different types of insulation

Some types of insulation are considered conditionally edible for rodents, such as chipboard, reeds and polystyrene. By eating them, rats compensate for the long absence of food. The organic materials from which the heaters are made are perfectly digested and absorbed in their stomachs. Mice can gnaw polyurethane foam, fiberboard, MDF, PPU, and this is due to their physiological characteristics. Rodent incisors grow throughout life, so they have to be grinded down regularly.

Not only heat-insulating materials are damaged, but also shoes, clothes, furniture, wiring. Most of all, mice like to settle in jute, inside mineral or basalt wool. The soft material holds its shape well, is ventilated and retains heat well. Treatment with special chemicals or boric acid will help protect the insulation from damage. Plywood, DSP boards, which are great for insulating a frame house, are not always subject to mouse teeth.

Mice gnaw polyurethane foam what to do

Sometimes people amaze with their short-sightedness, bordering on stupidity. For example, there are those who are sure that with the help of ordinary polyurethane foam you can protect your home from the penetration of mice. They selflessly foam cracks-holes, and rodents not only do not disappear, but also multiply exponentially.

Mice don't actually chew on polyurethane foam because they're hungry and want something to eat before reaching more edible human supplies. There are more prosaic but vital reasons for this.

The first reason lies in the physiological characteristics of all rodents, without exception: the front incisors are constantly growing and, so that they do not interfere with normal food intake, they must be periodically grinded down. So mice sharpen everything, including polyurethane foam, but do not eat at all, as many people think.

The third factor is the simplicity and ease of gnawing through the moves. For safety reasons, domestic pests move around the house in a maze created by themselves. To blaze a path, to equip a hole in mounting foam is much easier than in brickwork.

What to do

Well, if the mice climbed into the heater, then it is problematic to smoke them out of there. Therefore, it is better to think about thermal insulation, which at the same time can serve as a barrier for rodents, in advance.

Experience suggests that pests do not favor the following materials with their presence, which in terms of useful properties are in no way inferior to mounting foam:

• expanded clay,
• foam glass,
• foam concrete,
• glass wool.

Ecowool is considered the best anti-mouse material in construction today. Why it is called so is not clear, because 20 percent of it consists of components that are not the most healthy for health: boric acid, borax. It is these poisonous substances that cause asthma attacks in rodents.

There is an opinion that rodents are afraid of penoizol, foam styrene and the usual foam, but as practice shows, its mice not only gnaw, but also perfectly use it to organize their own home and labyrinth.

If the foam is purchased and it is not possible to replace it with an alternative material, then in this case there is a way out: during the work, the treated area is abundantly flavored with glass broken into small crumbs.

Foam that mice fear

By the way, news has recently appeared that a certain European company has released polyurethane foam, which can scare away not only rodents, but also other household evil spirits such as cockroaches, bedbugs, etc. It does not contain pesticides that are hazardous to humans.

Abroad, miracle foam appeared in March 2012, but it never reached the Russian construction market.

Although, if you try, you can make such foam yourself, because the bitter ingredient is not a secret, it is denatonium benzoate.The foamed surface is abundantly treated with a solution, and, perhaps, rodents will not want to try it on the tooth.

To the question: do mice gnaw polyurethane foam, the answer is given. But whether to use it in the construction business or not, it is up to each individual to decide.

About the use of heaters

One of the reliable insulation for the house, which retains heat well, absorbs noise, is non-flammable and inedible for rodents, is expanded clay. It is made from clay, which is cleaned, wiped, then granules are made from the resulting plastic solution, which are hardened at a certain temperature.

Cooling down, expanded clay acquires a small weight, and at the same time it is durable. It has small, medium and even krypnye - 10 - 25 mm in size - fractions. Mice and rats will not be able to exist in such material, as they will drown in the thinness of its particles. Expanded clay insulates interfloor and attic floors, basements, it is permissible to use it for walls.

Foam glass, which is produced in slabs and in bulk, is also not eaten by rodents. In the loose version, it is similar to expanded clay, it is used to insulate walls, floors, and ceilings of a house. It is customary to mount the slabs on the walls from the inside or from the outside, lay them on the floor, concrete, bitumen, building glue or expanded clay, which has small fractions.

Foam glass is made by melting and foaming glass. The material is strong, durable, environmentally friendly, well resists moisture and ultraviolet radiation.

Ecowool is a fairly new material. Rodents do not like ecowool, because it contains phosphoric acid, which causes them dehydration and suffocation. Ecowool is made from cellulose, harmless to humans, antiseptic, fireproof, releases moisture when heated, dampens noise well, does not rot and decompose, and is durable. Used both inside and outside the house.

Foam concrete is produced in mortar and blocks. Rodents don't eat it either. The blocks are suitable for building and wall insulation. The composition of the material that is used to insulate the house from the outside or pour the mass into the middle of the masonry during construction includes water, sand, cement and a foaming agent. It is used for thermal insulation of floors and ceilings. Light in weight, environmentally friendly, easy to process, non-flammable, non-rotten.

Penoizol - foam in liquid form. Spraying on the walls is carried out using a special compressor. Mice and rats are happy to gnaw on this type of foam. In ordinary polystyrene, pests make nests and gnaw through passages.

Penoplex shows resistance to high and low temperatures, exposure to chemicals, possible deformations, resists moisture, transmits light, is environmentally friendly and safe for human health. Extruded polystyrene foam is strong and lightweight, used for thermal insulation, sports fields, ice arenas and refrigeration equipment.

What mice and rats rarely gnaw through

There are a number of thermal insulation materials that rodents rarely spoil. But it depends on the thickness of the insulation, its actual density, the structure of the wall (ceiling). If you apply additional protection measures (treatment with special compounds), then the mice will not gnaw the following types of heat insulators:

• Mineral wool or glass wool. The material attracts rodents with a low density, they can use it to build nests. Glass wool adversely affects the health of rats, which is why they are afraid to come into direct contact with it.
• Extruded polystyrene foam. Unlike polystyrene, it has a higher density, which prevents rodents from making moves in the material.

Mice and similar animals love to gnaw on foam plastic, fiberboard, chipboard, penoizol. This must be taken into account at high concentrations of rodents.

What is the reason

Mice even gnaw on plastic, but the reason is not only the constant search for food: their front teeth grow throughout their lives, so they have to be grinded down.Polyurethane foam is also included in their "therapy", due to its porous structure. It does not contain harmful substances, but it does not carry a nutritional function for mice: they gnaw on building materials due to other motives. Among their "victims" we can mention a dozen seemingly durable raw materials:

• Thick paper, cardboard;
• Plastic and plastic;
• Rubber, even the most durable;
• Polyethylene and burlap;
• Even bricks!

Firstly, many people naively fill the gaps between the door frame and the opening with mounting foam, the gaps around the pipes facing the street. This decision is erroneous, because miniature rodents will quickly gnaw through the material and penetrate inside. But even this is not the most unpleasant thing: mice are distinguished by good intelligence, so they use foam crushed with sharp teeth to build a cozy nest.

Conclusion

So, do mice gnaw polyurethane foam? We have found that the answer is definitely yes. Especially if they need to make (restore) a passage or insulate their lair with fragments of porous building material. It's just that the rodents won't go after her. Foam is an inedible substance, and therefore, as food, it is not interesting to them. And with a little “retrofitting”, you can quite secure your construction foam seams from rodents encroachment on them with your own hands.

Foam from rodents KILLER RAT - rodenticide, bait in the form of foam, for the destruction of rats and mice

Rodenticide agent, ready-to-use bait in the form of white foam or the color of the applied dye in an aerosol package. Destruction of rats and mice by the population in everyday life.
