Mice prefer not to live close to people who are a threat to them. On the other hand, they want to stay warm during the cold autumn, winter, and spring. If they find the third option that implies staying warm and fed but not interacting with people in the house too much, they will infest your house. If you start seeing mice during the day, it means that they feel too comfortable in your house to hide from anyone. It happens rarely since they prefer to sleep until the night like any nocturnal animals.

Mice look for a safe space not only in cold temperatures outside or the lack of crops, but they also get inside the house to build a nest and raise their offspring. If there are cracks in the walls, they will quickly get in them. It is hard to notice a mouse until there is a whole family of them. You might not even have food in your kitchen to attract mice. They can feed on walls, chewing the wood, rubber, and aluminum.

Where Do Mice Hide?

Mice can hide almost anywhere around the house if it is far away from you. They can build a nest on the ceiling. The place must still be warm and easy to access, so a mouse can go outside to get the food and safely come back. Are you wondering: ”Do mice travel in packs around the house?” The answer depends on their intentions and quantity. Usually, a mouse can travel in search of food. Yet, you can see several of them if they need to feed the family. Pay attention to the following spots where mice can hide:

  • Drawers and behind them;
  • Kitchen cabinets;
  • Bathroom cabinets;
  • Every wall in the house has empty spaces inside;
  • Washing machine and any corner of the kitchen unreachable for humans;
  • Furniture. Mice prefer wooden furniture;
  • Attic, garage, or basement, if there is warm enough for them;
  • Cardboard boxes you keep in the house.

If you have a shed in your yard, you can start the check-up procedure from there. This is a perfect hiding place for mice. They can also build nests in the woodpiles and shrubberies.

Determining the Scope of Your Mouse Problem

Trying to figure out does one mouse mean an infestation? Usually, it does. One mouse is a rare case. Normally, they prefer to live in packs. Yet, there is no totally accurate way to calculate the number of mice that are dwelling in your house. You can notice that there is more than one mouse based on the sounds you hear, droppings you see, or even urine you smell. Pay attention to the following signs:

  • Set of tracks left from mice. You can calculate the number of paws you see. To do this, the traces must be visible;
  • Droppings on the floor. While mice defecate wherever they want and leave not one but numerous droppings, you can calculate the piles to understand how many mice were there;
  • The sounds you hear. Listen to the walls during the night. Do you hear lots of noise? One mouse would be quieter.

If you want to find out the number of mice for sure, you can set up motion-activated cameras. They also have to be night sensitive and of a high resolution. You will receive the warning right after one of the cameras notices the movement. Still, you might have a problem with distinguishing one mouse from another. Unless they all line up and stare into the camera, your calculations will not be 100 percent accurate.

How many mice live together on average? Usually, it is a family of mice. It can consist of 5-8 mice in the nest. Mice are really productive creatures and have numerous children.

Identifying the Pest Control Problem in Your Home

You don’t need to wait to see a mouse running close to you to understand that there is a mouse infestation in your house. There can be several generations of mice and prosperous mice colonies till you finally see one mouse. The droppings are too small to notice if you are not looking for them specifically. Moreover, many people wonder: “Do mice come back to the same house?” mainly when they suspect that new species will come back. The problem is still there. Mice can choose your house randomly and do everything to avoid direct contact with you.

The feces you find is the sign that you have a mouse infestation. The more of them you see, the more mice you have. You can look for them near any source of food. They prefer rice, cereals, and anything they can get. Usually, mice defecate and urinate where they eat, so you can start your search with the cabinets and around the kitchen. If you leave crumbs on the table, someday you might notice black “raisins” instead of them. Don’t touch them since urine or feces can transmit diseases. If you see them, you have to quickly get rid of them and clean the room.

If you don’t see anything suspicious, take a look at the legs of the furniture. Mice can leave tooth marks on them. The more mice you have, the more damage they create running around at night.

To avoid mice infestation, you have to make sure that there are no cracks or gaps inside the walls. Once you notice the hole, react immediately. Don’t wait till it gets worse. If you prefer to postpone the mending till the mice disappear themselves, this will never happen. Instead, you will have a severe infestation that not every pest control can handle, which will cost you a fortune. Even if you have one mouse at home, you have to get rid of it immediately. Put the traps, use specific products to kill mice, and buy an ultrasound trap that will scare away the pest.
