Rats

Rats can be found nesting in private and public properties, in burrows, crawlspaces, trees, ceilings or attics.

Because rats can cause property damage, contaminate food and spread disease, it’s important to:

  • Learn to identify evidence of rats
  • Prevent rats from entering your property
  • Safely remove rats from your property

Signs of rats on your property

Evidence of rats in and around your property includes:

  • Droppings
  • Underground holes
  • Chewed food
  • Scratch marks on walls and other surfaces

How to prevent rats from entering your property

  • Identify entry points outside your home
  • Check your home foundation, roof, siding and windows
  • Use heavy wire mesh to cover vents
  • Use metal sheeting to cover holes
  • Remove attractants
  • Consider removing any source of food in your yards, such as vegetable gardens, bird feeders, fruit trees and bushes
  • Make sure compost receptacles are in a state of good repair to ensure rodents can’t get inside them

If you decide to use traps, consider the following:

  • Use enclosed bait stations, as they will help keep other pets or wildlife safe from exposure to rodenticide
  • Only use snap traps indoors, as they can harm wildlife, including raccoons, skunks and squirrels
  • Ensure someone is home and monitoring snap traps to prevent any unintended injury
