A rat infestation is a serious problem that can cause significant damage to your home and property. Millions of rats have been sighted in various households in the U.S., and these rats can contaminate food sources, damage insulation and chew wires, and spread diseases to humans and pets. To protect yourself and your family from the dangers of a rat infestation, it’s essential to understand the common causes of these infestations.

How To Identify A Rat Infestation?

The most obvious sign of a rat infestation is seeing a rat scurrying around your home or property, but there are other tell-tale signs that you should be aware of too.

Look for gnaw marks on wood or wires, tracks in dusty areas such as basements or attics, and holes in walls or floors where they might enter your home. You may also hear scratching noises coming from inside walls if there is an infestation present. Here’s a look at other common causes of rat infestations.

Food Source Attraction

One of the main reasons why rats are attracted to homes is because they have access to an abundant food source. Rats love easy-to-access food, so if you leave food out in the open or don’t clean up messes promptly, you are more likely to attract rats. In addition, outdoor compost piles or pet food dishes left outside can also be attractive food sources for rats. To prevent an infestation from occurring due to this factor, ensure all foods are stored away correctly, and all messes are cleaned up quickly.

Entry Points

Rats often enter homes through small openings or holes in walls or floors. If you have any cracks or gaps around windows or doors, these should be sealed off immediately, as this could open up rats to enter your home. Here are ways to do that:


Your first line of defense is fencing around your home. Fences can discourage rats from entering your property, as they must climb over or dig under the fence to gain access. Additionally, you can use a robust Trex gate for your fence, a metal gate that is difficult for rats to climb. They won’t be able to make a hole in these gates, making it impossible for them to enter from the outside.

Filling Gaps

If there are cracks and gaps around windows, doors, or other areas of your home, you can use caulking or steel wool to fill them in. This will help block off the entry points for rats so they cannot get in.

Weather Stripping

Weatherstripping is another way to help prevent rat infestations by keeping them away from entry points in the house. Weather strips are relatively inexpensive and easy to install around windows and doors.

A cluttered part of a home


If your home is cluttered with items like cardboard boxes or paper bags, this could provide an ideal environment for rats as it gives them plenty of places to hide while they search for food sources in your home. Therefore, ensure all clutter is cleaned up regularly and any boxes stored away correctly so as not to attract unwanted guests into your home. Here are some tips when decluttering:


The first step to decluttering is to organize your space. Start by grouping items into categories that make sense, like kitchenware, books, clothes, etc. This will help you better understand what is taking up unnecessary home space.

Throw Things Away

Once you’ve organized everything, it’s time to start throwing things away. If you haven’t used an item in the last year, chances are that you don’t need it. Get rid of things that are taking up space and creating clutter in your home to help prevent rat infestations.

Decluttering is one of the easiest ways to deal with rats. It’s also a great way to reduce stress at home, so do it when you can!

Rat infestations can be dangerous and challenging to get rid of once they occur; however, by understanding the common causes, you can take steps to prevent one from occurring in the first place! So take around your property, and make sure you deal with the problems before it’s too late! Taking steps now can save you time and money when dealing with a rat infestation!
