How To Prevent And Control Rodents

As the temperatures outside begin to cool, rodent prevention and rodent control become issues all homeowners need to think about. How do I know what pest you have? How do I prevent and control rodents?

 Identifying Your Rodent Invaders

House Mouse

House Mouse

There are three main rodent types seen this time of year in the St. Louis area. The first is a house mouse. A house mouse has grayish-brown fur, with a tail equal to its body length. Homeowners often first know rodents are present due to the presence of droppings, making it important to know what to look for. House mouse droppings are roughly 3/8 inch long, black, and very hard.

Another rodent common now is the white-footed deer mouse. This mouse has brown fur with a white belly, as well as white feet. The droppings are similar to a house mouse, but since these mice are associated with Hantavirus, sweeping up their droppings on your own could be deadly.



The last rodent seen moving indoors this time of the year is the Norway rat. This rat has brown or gray fur, and a shaggy coat. A Norway rat’s ears and tail are covered in scales. The total body and tail length will average 8 inches to 10 inches. Norway rat droppings are about 3/4 inch long, black, and have a “hook” on one end.

How Did I Get Rodents in My Home?

Rodents seek warmth and food sources inside your house when the weather outside begins to cool. They look for tiny openings to gain entry into your home. Mice only require an opening as small as a dime to gain access; for rats, it is the size of a quarter.

Common entry points are:

  • Gaps where the gutter line meets the roof
  • Foundation cracks
  • Warped siding
  • Garages
  • Where utility lines enter the home
  • Sewer lines (access gained through floor drains or the toilet)

Preventative Measures To Take

  • Professionally installed exclusion measures (e.g. sealing visible foundation holes)
  • Baited and monitored rodent stations outside of the home
  • Replace garage door seals
  • Keep indoor food areas clean of crumbs, wrappers, and dirty dishes
  • Contain trash in metal receptacles (plastic can be chewed)
  • Cover utility entry points
  • Do not use foam insulation to seal home, as rodents can chew through this
