Whether you hire a mice exterminator or not, the advice will be the same: The best way to get rid of rodents is to stop them from getting inside your home in the first place.
For example, you can:
Seal up gaps and holes in your home, especially near kitchen cabinets, refrigerators, doors, the basement and the attic.
Store garbage in containers with tight-fitting lids (and take the trash out regularly).
Put pet food and water away at night.
Clean outdoor grilling areas and appliances.
Keep bird feeders away from your home.
Place traps and baits around your home.
However, consider hiring a pest control company if you’re unable to control your rodent problem with the tips above.
