Entry points for rats

It just takes one small hole for a rat to invade your home. That hole can be as small as a dime, and once they are in, then you have a whole other problem to deal with. Here are some other ways how rats get into your home.

Wall and foundation cracks

Rats outside your house often lurk around and find good entry points for your home. One of the easiest points to access are the cracks and holes in walls and foundations.

Foundation cracks are near ground level, and some rodents even dig through small cracks they can find. To keep them away, use waterproof sealants. Sealants work best for big entry points, but you can use caulk to fill small holes.

Aside from getting through bottom entrances, mice get inside your home through holes in your roof. One small hole can already welcome rats and squirrels to get in.

Moreover, pests may invade your attic. Check it from time to time and look for roof gaps that can allow them inside your house. Roof rats show no mercy on chewing ridge cap plugs, and that's another point of concern. The damage can be extensive.


Rats can pass even through dime-sized entry holes. Hence, it's easy for them to invade your home by passing through your chimney.

Your chimney is an opening that begins from your fireplace and ends up in your roof. It quickly exposes your home to any pest.

Professionals use grates or caps to install in chimneys as protection against rats who look for warmth inside your home.

Vents and windows

Air vents and window gaps are often left open, and these serve as fixed entry points for pests to enter your home.

Seal gaps you can find in your vents and inspect your windows for any holes that can allow rats to get indoors.

Pipes and wiring

Hollow materials like pipes provide easy access to mice. Moreover, these pests follow your wiring system and use it as a guide to locate food sources inside your home.

Large packages

This possibility may surprise you, but it's not an insane idea to learn that there might be rats hiding in large parcels or packages of food you just brought inside your home.

You may not notice them right away, especially when you didn't bring out the contents once you laid the package or box on the table.

What attracts rats to your home?

Just like most pests, rats thrive on sources of food and water. They look for shelter and warmth, and that makes your cozy home a rat's favorite food hole.

Rats never tire of looking for food

Rats aren't particular about types of food. They are not picky, especially when it comes to looking for food at night. These pests would chew on your wood, insulators, and even wires.

It's not an uncommon sight to see mice feasting in the contents of your trash bin. These rodents have strong sensors that allow them to sniff on foods and locate them easily. Leaving your food uncovered makes it an easy target.

Rats look for warmth and shelter

Since rats are warm-blooded animals, they always look for places that will provide them with warmth. You have to consider that in colder weather such as we experience in Asheville area, they will want warmth, and your home is absolutely fine with them. They dig pits in your homes so they can build their nests and mark certain corners of your home as their territory.

Rats need water supply

When there is no water source from the outside, a pest's instinct is to look for the leaking pipes and sometimes your pet's water bowls. When the rats see that they have easy access to water, they will stay longer in your homes.

Tips to prevent rat infestation

Before rats infest your homes, it is best to consider doing these tips so that you can keep them at bay.

Inspect your home for any gaps or holes

Seal entry holes and cracks that you can find with hardware cloth, cement, and plaster. For windows, you can use weather strips to cover the gaps.

Practice proper food storage and disposal

Cover garbage bins at all times to prevent rats from gnawing the leftover food and trash inside the container. Refrain from leaving leftover food open and lying on the floor.

Make a compost pit

Ripe fruits from your garden should already be picked up and make a compost where fruits and vegetables can be buried just if they are not acceptable to be eaten.

Seal pet foods in containers

Feed your pets during the day and store dog or cat food in tightly sealed containers.

Dispose of any old and broken stuff

Throw away old appliances that you no longer find useful to ensure that these don't become chewing targets for rats.

Set up traps and poisons

Use traps or rat poisons that are available in the market. Keep the poison away from children or anyone in your family.
