Check inside and outside your house for gaps or holes and seal them up. Rats and mice can get into very small places. Mice can squeeze through a hole the size of a nickel, and rats can squeeze through a hole the size of a half dollar.
Rodents can get in your home from tree branches that hang over your roof. Keep trees and bushes cut back to prevent access.
If you think you have rats or mice in your home take the following steps to protect your health:
Put all food in sealed containers.
Throw away all food and drinks that may have come in contact with rodents.
Clean cookware and cutlery before using.
Wash hands well before preparing food, eating, or drinking.
Wear shoes around the house and do not sleep or lie down on the floor.
Contact a healthcare provider right away if you are bitten by a rat or mouse.
How to Kill Rats or Mice
Trapping is recommended over poisons to remove rats and mice. The best trap is the snap trap.
Poisons are not recommended because children and other animals may eat the poison and become ill, or in some cases, die. Poisoned rodents can die in hard to reach places, causing a very bad smell. If you want to use poison, contact a qualified pest control company.
Dead rodents must be first wrapped in newspaper, or placed in a plastic bag before putting the animal in the garbage. Injured or sick rodents must be killed. Try not to touch the dead rodents and use gloves if possible. Always wash your hands with hot water and soap after touching a rodent (even if you wore gloves).
