Rats love to inhabit homes and surrounding yard areas.

Rats are extremely sneaky and can easily enter a home undetected.

There are, however, a few ways to detect if you have a rat infestation in your home. 

Look for Droppings

One way is to look for rat droppings. Rat droppings are small, black, and rod-shaped. They are also about the size of a grain of rice.

Rats hangout under your house, too.

Listen for Rats

Another way to tell if you have rats is to listen for them.

Rats make a high-pitched squealing noise when they are scared or in pain.

If you hear this noise, it's likely that you have rats. 

Look for Footprints

Lastly, you can look for footprints or tail trails. Rats leave footprints and tail trails in the dust and dirt as they walk around. If you see any of these signs, it's time to take action and get rid of the rats!

The Dangers of a Home Rat Infestation


Rats can pose a serious danger to your home and family. They can carry diseases, such as the bubonic plague, which can be deadly. 


They can also damage your property and chew through wiring, which can lead to electrical fires.

Rats will chew into electrical cords, cables, and wiring.

It is therefore important to take action quickly if you think you have a rat infestation and get rid of them as soon as possible.

How to Treat a Rat Infestation


You can use traps to catch the rats.

There are several types of traps that can be used, including snap traps, glue traps, and live traps. 

Just be very careful that your small children or pets cannot get anywhere near your traps.

Rats don't have to be killed with a snap-trap. They can be caught in a rat cage.


Rodenticides to kill the rats. Rodenticides are poisons that kill rodents. Be very careful when using these products and follow all instructions carefully. As with traps, ensure your small children and pets cannot get anywhere near the rodenticides you've chosen to treat your rat problem with.

Rat-Proof Entrance Points

Seal up any entrances that the rats may use to enter your home. This will help keep them from coming back in future.
