Key facts about mice

Mice are mammals and rodents. Their closest relatives are jerboas, rats, mole rats, hamsters, chinchillas and guinea pigs.

The mouse is small, its body length varies from 1 to 8 inches (3 to 20 cm), and it weighs from 0,5 to 1,7 oz. (15 – 50 g). Mice are agile and fast animals, with a pointed muzzle, large rounded ears, and small protruding eyes. These rodents have good eyesight, they distinguish shades of red and yellow. The mouse body temperature ranges from 99.5° F – 102.2° F (37.5° C to 39° C). A distinctive feature of mice is their long bald tail.

Interesting fact: The need for gnawing and nibbling is explained by two pairs of constantly growing chisel-like teeth on the upper and lower jaws. To grind them down, mice must gnaw solid objects.

How and where do mice live?

Mice can be found worldwide, except for extreme northern and high-mountainous areas. They live in large families, because this way it is easier to defend, build houses, grow offspring and find food. Rodents are fidgety and gluttonous animals. This helps them survive winter and cold seasons.

In nature, mice spend most of their time in burrows, which they dig at a depth of about 2.3 feet (70 cm). The length of passages can reach 65 feet (20 meters). Mice are thoroughly engaged in the construction: they build separate burrows for temporary and permanent, summer and winter residence.

In winter burrows at great depths, they arrange a storeroom for supplies, where from the fall they begin to collect grain and seeds.

The lifespan of a mouse depends on the habitat: climate, nutrition, diseases, predators. Far from humans, they can live for about a year, but next to human dwellings a mouse can live up to 4 years.

The mice multiply rapidly. At the age of 10 weeks, a female mouse becomes fertile and ready to breed. It can give 3-12 broods annually, each of them may consist of up to 9 mice. In wild nature, the mouse reproduction occurs only in warm weather, and near human dwellings – all year round. It is not difficult to calculate how many rodents may appear in a year if only one mouse has settled down at your place.

What do mice eat?

The diet of the mouse depends on its habitat, but usually, it prefers grain products: wheat, barley, oats, buckwheat. In forests, mice feed on plant seeds, cedar nuts, hazelnuts, acorns, insects, larvae or spiders. House mice have a varied diet. They get adapted to humans and consume everything that has not been removed from free access: bread, cereals, dairy products, lard, sweets, sausages. They don’t need a lot of water, as the body of a mouse produces water from plant leaves, vegetables and fruits.

Mice are prey for many animals: foxes and Arctic foxes, ferrets, lynx, ermines and even wolves. One predator can consume up to 30 mice per day. These rodents have enemies everywhere: they are also prey for snakes, boas, pythons, hawks, kites, eagles and owls.

What harm and benefits they bring?

The greatest benefit these small animals bring is their use in scientific work. For several centuries, mice are used to conduct all sorts of laboratory experiments. They were chosen due to their extraordinary fecundity and the similarity of their genome to the human one. Zoologists grow special prey mice for pythons, boas, ferrets, cats and owls.

The presence of a mouse in a house cannot be detected immediately, as they are active at night. During this time, they can do a lot of harm:

  • The need to chew and gnaw solid objects can lead to damaged furniture, products, wires and soft toys.
  • It can carry house mouse diseases that contagious for people: salmonella, plague and typhus.
  • Due to the house mouse diseases people can get infected by products, that were in contact with a mouse.
  • Rodents leave mouse poop containing viruses and bacteria. Even vapors of their waste can carry diseases. If mouse poop is found, it should be removed with caution, after treatment with a disinfectant.
  • All rodents are infected with insects: mites and fleas, which are transferred to pets along with house mouse diseases. It is necessary to know that dog’s immunity (unlike cat’s) cannot cope with house mouse diseases.
  • The risk group susceptible to house mouse diseases includes children and people with weakened immunity that are vulnerable to viruses.
  • In search of food and favorable conditions, a mouse can migrate over long distances. Thus, they can carry the house mouse diseases from one dwelling to another.
This is interesting: due to the need to gnaw, mice did a good job in 1942, during the 2nd World War in the Soviet Union. Mice managed to disrupt the attack of fascist tanks, that were disguised in haystacks during winter. They chewed everything that can be chewed inside the tanks – wires and hoses. By the time of the attack, 70% of the tanks were disabled.

In homes and apartments, there are a lot of wires from household appliances. If they are damaged – this will disrupt the operation of household devices. Since electrical wiring is hidden in most cases, it would be challenging to find the place of the damage and to get rid of mice which caused this damage.

How to detect mice in the house?

  • Under the skirting, small holes appear (next to them are small sawdust);
  • You notice mouse poop on the floor;
  • There is a musty smell, which is difficult to ignore;
  • You hear strange mice sounds, such as rustling or squeaking at night;
  • If there is a cat in the house, it becomes nervous and rushes from corner to corner.

Biological method

The best way to get rid of mice without using chemicals is to use their biological enemies – cats. In this case, you do not have to use poisonous substances, but the thing is that you need to keep a pet and take care of it.

Cons: not all cats are interested in hunting and can help you get rid of mice. Ordinary underbred cats are usually best hunters, while newly created breeds have completely lost the hunter’s instinct.

Physical method

How to get rid of mice more effectively than with a biological method? We recommend you to refer to a physical rodent elimination which implies using mice traps. To get rid of mice you can use various types of mice traps (mechanical, electrical, tunnel and live mice traps). If the mouse hole or place of stay is found, you can use foam or glue traps. They should be placed in narrow aisles (behind the refrigerator or behind the cabinets) so that the animal couldn’t escape any of these mice traps.

Chemical method

Poisoning by chemical mice traps is a fast and effective method of mice destruction. Inside mice traps, there is an edible mouse bait pollinated with poisonous powders. The mouse bait can be also made in the form of a suspension or a gel. The method is used in houses, country houses, farms, greenhouses and storage facilities.

Cons: using mouse bait poisons may be dangerous. To use chemical mice traps you need to isolate pets during the premises processing. There is a risk that a poisoned mouse may die in the cellar or under the floor. In such cases, it would be extremely difficult to get rid of mice disgusting smell for several months.

TomCat Mouse Killer is a bait station designed for killing mice. It has a small entrance hole that wouldn’t let your pets or little kids to touch dangerous bait. It also won’t help you deal with rat infestation, so watch carefully when you buy this kind product. Its size and formula depend on which rodent you’re after. In one pack you will find one bait station and 16 block baits you can put into it. Each of the blocks can kill up to 12 mice. Bait uses 0.01% Bromethalin as an active ingredient which is lethal to mice.

Your pets don’t have a chance to get inside the cartridge as it is tightly adjoint. It has also proved to be weather resistant during product laboratory tests. To place the bait put it into the cartridge and find the place that is often visited by mice.

The bait of this kind works both outdoors and indoors, but seems to show the highest efficiency level during winter months when there are very little other rodent food sources. Mouse gets to eat a bit of the bait and then leaves the house; its death comes during the next hour. One bait station may not be enough for stopping large infestations, but it’s great for controlling vagrant rodents.

  • quick lethal effect;
  • safe to use with pets and children in the house;
  • may be used both indoors and outdoors;
  • perfect for controlling small infestation.
  • may not be as effective during summer month as it is in winter;
  • one station is not enough for the severe infestation.

Professional deratization

If you cannot manage the task of getting rid of mice on your own, or the number of rodents increases rapidly, it’s better to use professional help. Getting rid of mice or deratization (how this process is called professionally), is carried out by sanitary and epidemiological service will ensure the complete destruction of house mice. The work of getting rid of mice is carried out in several stages:

  • specialists examine premises and determine house mice habitats;
  • the causes of house mice invasion are identified;
  • deratization methods and chemical preparations are selected;
  • getting rid of mice is followed by quality control;
  • deratization takes from 30 minutes to 2 hours;
  • specialists use several components to prevent insensitivity to one of the house mice poisons;
  • if necessary, the getting rid of mice procedure is carried out once again;
  • after a certain period, professionals take preventing measures impeding the emergence of house mice.

The mouse repellent method

The mouse repellent method – a humane way to get rid of mice.

This is the most effective, safe, modern and simply the best way to get rid of mice. To repel rodents, you can use devices that produce ultrasonic vibrations that are inaudible to humans but intolerable for mice. Ultrasonic is the mouse repellent sound that can help you for sure.

Models of devices that produce the mouse repellent sound are subdivided depending on the area of influence. They are completely safe for humans and pets (except for the mouse family pets, such as guinea pigs or chinchillas). The mouse repellent sound devices operate from the mains or from batteries. You can use them on any premises.

Cons: pricey.

The best way to get rid of mice: find your own in our TOP 5-detailed description of getting rid of mice

Let’s consider 5 commonly used and effective ways to get rid of mice, their pros and cons, make a rating and choose the getting rid of mice method that suits your needs.

#5: Glue traps for mice

The product is effective, but you will have to wait quite a long time for results.

  • Action: glue traps for mice are applied to the cardboard, piece of plastic or wood. Such mice traps are installed along the route of a mouse (behind the refrigerator or behind the cupboards). As house mice are smart enough, they quickly remember dangerous places and avoid them. Therefore, a mouse bait is placed so that mice do not have the opportunity to skip it. Reacting to the mouse bait, the pest gets into the glue and gets stuck.
  • Efficiency: the glue traps for mice method is rather difficult to use, mice don’t always get stuck in the adhesive mice traps. And for the owners the glue traps for mice are not the best way, as they will see how the stuck animal is suffering and squeaking. In specialized stores you can buy CRANACH Glue Boards, Tomcat glue traps for mice.
  • Duration of action: the glue traps for mice remain sticky for a long time until covered with dust, dirt or water. In this case, glue traps for mice must be replaced.
  • Potential harm: this method is not suitable for houses with pets. Another drawback is that glue traps for mice can stain the floor, carpet or furniture.

#4: Mice traps

  • Action: Mousetraps consist of a mouse bait and a holding device with a spring. When the house mouse tries to pull the bait, it releases the holding hook and triggers the spring mechanism. It beats the animal and presses it to the base of the mousetrap. Most often death occurs instantly.

Electronic mice traps are considered up-to-date. There is a mouse bait inside, while the animal is killed by high voltage shock. Such mice traps are manufactured by Swissinno, Victor Multi-Kill.

  • Efficiency: Mice traps cope well enough with rodents’ destruction, especially with a properly selected mouse bait. Each time you need to pull out the dead animal and throw it away. Such a task is not for the faint-hearted. Besides, the dead mouse should be removed carefully, as it may carry house mouse diseases.
  • Duration of the action: mousetraps are ready for use, once the mouse bait has been placed and the spring has been cocked. They can help you get rid of mice in the house quickly.
  • Potential harm: Mice traps are safe for adults, but if there are small children or pets in the house – the device must be kept away from them. Never let the child touch a mousetrap, as it may lead to the finger injury.

Mousetraps with a wooden base are not hygienic. After use, mouse blood may remain there, and it will have to be thoroughly washed. This is an unpleasant and dangerous procedure. Mice traps with a plastic base are much easier to clean.

TomCat is the top label for dealing with rodent pests, and in this product, the producers have combined classical mousetrap efficiency with the modern design and newest grab tab techniques. There are two traps in each box, so you might need to buy more of them if you suspect a greater infestation.

If there’s only a couple of mice in your house, the hunt will be easy. To set the trap, bait it with peanut butter, TomCat Attractant or any other bait of your choice, then find a place where recent rodent activity has been indicated. Mice favorite spots are usually the ones near stoves, fridges, washing and drying machines, and house structures.

Press the set bar and place the trap perpendicular to the wall with the bait facing it. When the mouse is caught, use the grab tab to replace it. You don’t need to touch the rodent to dispose of it. If after a day or two no mice are caught try to move the trap to other place or change the bait. Producers recommend their other product, TomCat Attractant Gel for their traps. You may try it to make your mice killing combination more solid.

  • classic way of dealing with pest rodents;
  • safe for your fingers;
  • contains no chemicals or other dangerous elements;
  • works great for solving small mice problems.
  • does not suffice for greater infestations.

#3: Organic mouse repellent

  • This Organic Mice Repellent Peppermint Oil Spray from mdxconcepts contains natural oil extract that affects the taste and olfactory receptors of mice. This mouse repellent smell brings serious discomfort to mice irritates them and forces to leave the premises. The mouse repellent spray is widely used in airports, parking lots, ports and gardens for treatment of tree trunks.  It should be applied to the previously cleaned surface, using a sprayer. One 16 oz bottle is enough for one thorough indoor spraying.
  • Efficiency: The mouse repellent spray can be applied indoors and outdoors. It doesn’t damage furniture and there is no need to look for dead mice on the territory after its use – they will simply leave the zone of mouse repellent spray’s action.
  • Duration of action: the effect of the mouse repellent spray lasts for a pretty long period, but I’d recommend reapplying it every 3 months.
  • Potential harm: the spray is applied to places where it can safely stay for a long time without disturbing people. It does not harm animals, the environment and people, because there are no pesticides in it.

The sprayer is conveniently made to fit any small dark corners of your home or garden that is infested with mice. And you don’t have to leave the premises after applying it! Just enjoy the natural herbal smell. The effect is seen rather quickly: in case of a small infestation, just a few days is enough to get rid of all the mice there are. Still, if there’s a severe infestation in your house, this type of product may not handle it properly.

  • all-natural organic ingredients;
  • safe for family and pets;
  • pleasant smell;
  • convenient sprayer.
  • will not handle severe infestation.

#2: Ultrasonic mouse repellers

  • Action: the instruments use radiation frequency harmless to humans and domestic animals but causing the mouse repellent sound (16-70 kHz). The ultrasonic frequency is changed automatically every 1-5 minutes. This does not allow mice to get used to it.
This is interesting: according to scientific research, the ultrasonic mouse repellent sound effect starts from day one – they get fussy and start hiding, in 5 days they start going mad, and in 10 days suffer from panic, look for escape and leave the impact zone by any means. Experimental mice were in closed cells, so they could not leave the place. Mice invading your house will always find the way out and leave the place running away from the mouse repellent sound.
  • How to use: the mouse repellent sound device is selected considering the area. The appliance is connected to the mains. When installing mouse repellent sound device, make sure that the radiation panel is facing the center of the room. The maximum effect is achieved due to the waves reflection from solid surfaces: walls, floor, ceiling. Soft objects (curtains, sofas) absorb ultrasound (mouse repellent sound).
  • Efficiency: easy-to-use mouse repellent sound appliances allow you to get rid of rodents in 1-2 days. Unlike all other methods, you don’t have to contact pests (pull out of mousetraps, tear off the mouse glue traps or look for poisoned mice). The repeller simply expels mice from the house.
  • Duration of action: the action of a mouse repellent sound appliance starts right away, and then for prevention, you should turn on the device from time to time so that the mice wouldn’t return.
  • Potential harm: the frequency of ultrasound radiation is harmless to humans and animals.
The only drawback of this method is the high price of ultrasonic devices. Depending on the premises size, you can pick up a repeller that costs from $20 to $100 on Amazon.

#1: Chemical method – The Only Choice In Case of Severe Infestation

  • Action: Mice poison can be sold in the form of baits from grain or granules, in the form of briquettes, suspensions, and mouse repellent gels. All toxic substances have only one drawback – a mouse can die in an inaccessible place and will produce disgusting smell for several months.
  • Efficiency: the death happens 3-4 days after the mice poison enters the rodent’s body. It is not recommended to use mice poison with an instant effect. Most effective products against mice contain brodifacoum (D-Con,). This kind of mice poison influences blood coagulability and causes suffocation. Rodents try to get out of their holes to fresh air, so they are not likely to die in the house.
  • Duration of action: the substance starts acting within 2 weeks after the pest consumes the mouse bait. By this point, you need to be ready, that mice are going to crawl out to open areas and die. Your task is to clean the territory from the dead bodies.
Important: they must be collected using gloves and special instruments. Never let your pets approach the dead animal. Fleas, ticks and lice will be looking for a new home and can find it on your cat or dog.
  • Potential harm: all rodenticides are dangerous for humans and their pets. It is necessary to carefully read the instructions, use rubber gloves and protective equipment. Use the mice poison in places inaccessible to other animals.

There are a lot of ways to get rid of mice. All you need is to determine which is the best way to get rid of mice personally for you. Remember: destroying rodents is just half of the task. You need to analyze why they have appeared at your place and what to do if they re-enter your home.

How to prevent mice invasion

Mice get into houses and apartments through cracks, garbage disposal, from cellars or through ventilation. At a great distance, they identify places with attractive food and conditions and move there. To avoid rodents’ invasion in the house, it is necessary to take preventive measures:

  • Cover the cracks in the floor or walls;
  • Check cellars and closets, to detect the appearance of rodents as soon as possible.
  • Keep the house and the kitchen clean;
  • Do not store products in plastic bags – this doesn’t stop mice;
  • Keep all grain and cereal products in tightly closed containers;
  • Keep cells with animals and birds clean;
  • Do not leave pet food overnight;
  • Never leave dishes with food or garbage bin with waste overnight;
  • Keep food in the refrigerator or in closable containers;
  • Always close the doors at dusk;
  • Cover the ventilation ducts with metal grids;

Your home is your fortress. But it can be easily accessed by a small gray house mouse. Getting rid of mice is difficult, dangerous and expensive. Therefore, it is better to prevent their invasion than to declare a war.

13 thoughts on “How to Get Rid of Mice in the House – Everything You Need to Know from A to Z

  1. My husband and I have been in our house for a long time and have never had to deal with mice, but I’m sure we have some now. I didn’t know that house mouse diseases could harm your dog’s immune system if they were to interact. We just got a new pup for our kids and I wouldn’t want anything to happen to her, so I’ll call a rodent control service that could help our house stay rodent-free!

  2. I have a very small Mouse in my cellar. It can’t escape cuz the stairs are too high. My cats don’t seem to want to catch it. It’s staying behind a big cabinet. I’m afraid it’s going to die back there and I’ll get maggots. Any suggestions to get rid of it without hurting my cats.

    1. TomCat bats should be helpful in your case. Read about them in a review.
      I hope it will be helpful.

  3. Mine is old house need to stay another 5 months. Suddenly noticed 3 days back some sound in hall in mid night after investigation found 2 mice running around. Tried using mice wood trap but did not work. Thinking of using Ultrasonic mouse repeller.

  4. we have a lot of mices in our house. i’ve seen mice multiple times during daytime running around in the kitchen and was caught by our cat.
    i could hear them between the walls. i finally got my husband to call exterminator.
    they spray pesticides interior and exterior, also put 3 block traps supposedly get them dehydrated and make them leave the house. i don’t think it is working as i still see a couple of mices and hear them “chit chit” constantly 🙁 should i look for a different company? i just wanna move out of this house

  5. A rodent spray that smells like peppermint? It seems like an oxymoron, but in a good way!
    I have a pretty awful rat problem at home, and I always feel guilty while using chemical pest sprays around my kids and my dog.
    But I think the natural rat repellent spray can help me out in terms of keeping my family safe from toxic chemicals. Thanks a lot for posting this!

  6. I like how you suggest how to get rid of mice such as using the mechanical, electrical, tunnel and live mice traps. My aunt told me that she saw a rat running in her basement and she is concerned about having more than just one rodent. I will recommend her to contact an extermination company so that they can go to their house and finish with that rodents.

  7. It’s so interesting that mice have to grind their teeth down because they grow too much. What would happen if they weren’t able to gnaw on things? It makes a lot of sense now why they do so much damage to their surroundings.

  8. It’s worth to say that I’m terribly afraid of mice. I learned about this fact only when my husband and I moved to a new house. Before that, I saw them only in pictures.
    Therefore, the question of how to get rid of mice in my house was very acute for me. I certainly would not be able to share a home with them. The traps did not suit me for obvious reasons (I have to see if the mice are caught), so we chose the BRISON Ultrasonic Pest Repeller.

    I understand that this is not magic, it’s science, but the effect is really magical. We have not seen a single furry tenant anymore. I can safely advise you to try it.

  9. Thanks Nicolas
    This was a very useful article and I felt much better prepared to tackle the problem using some of the products mentioned. Your knowledge was very clearly explained and help me feel informed in developing a strategy.
    Thank you
