Rodent Control

I have rats at my house. How did they get here?

Rodents such as rats and mice are attracted to areas with available food, water and places to nest. Rodents can squeeze through a hole the size of a nickel (mice) and half-dollar (rats) to find food and places to live. 

Why are rodents a problem?

Rats and mice are a nuisance and can spread disease. Rodents’ nests are messy, and they chew on structures, causing damage. Rodents can spread disease to people when handled, through rodent bites and by contact with rodent feces, urine or spit. Rodents can spread diseases such as plague, hantavirus and salmonellosis.  

Where do rodents live?

Most rats and mice live in nests or burrows. Burrows are holes in dirt or concrete and can be found under bushes and plants. Rat burrows often have an entrance and exit hole. 

How do I know if I have a rodent infestation?

Look for nests or burrows outside or inside a house. Look for droppings close to garbage or in nesting areas. Look for holes and gnaw marks on wood and plastic garbage cans. For rats specifically, check walls and grass for signs of runways—places where rats run along the same path many times per day. Check for rats and mice after dark using a flashlight. 

How do I prevent a rodent infestation?

Keep food for people and animals in containers with tight lids. Use a garbage can with a tight lid. Do not leave pet food or water out overnight. Get rid of clutter inside and outside your house. Clutter gives rats places to hide and nest.
