Mouse Control  Rat Control Icon

The most common breed of mouse in North America is the house mouse. They vary in colour from white to grey, and light brown to black. These critters have a strong sense of hearing and communicates with other mice by squealing — some audible to humans and extends to an ultrasonic range.

Did you know that house mice are known for their quick reproduction? One female house mouse has the ability to produce up to 8 litters per year!

Look For Droppings

The easiest way how to determine mice from rats is based on the their droppings. For rats we could say that their droppings are bigger than a grain of rice. Mouse droppings are smaller than a grain of rice.

Where Are They Living

Rats prefer not to share their living space with humans so mostly only two indicators are possible

  • droppings in the attic/crawl space/furnace room, or
  • noise in the walls/ceiling/floor.

Mice, on the other hand, have no problem entering the kitchen, living room, or other places within your house/apartment.
