How Do You Get Rid Of Rodents?

Now that you know the difference between mice and rats, what can you do to get rid of them? Check out these 7 tips for getting rid of both mice and rats:

  1. Know The Signs. Signs of both mice and rats include droppings, gnaw marks, tracks, and burrows. These signs can especially be seen around food sources.
  2. Keep It Clean. Mice and rats will come into your home in search of food. Store food in airtight containers. Don’t leave food or dirty dishes out overnight. Wipe crumbs off the counters. Sweep and vacuum floors regularly. Secure your garbage. Don’t leave pet food out overnight and store it in airtight containers, also.
  3. Don’t Let Them In. Eliminate any entry points into your home. Seal any cracks in your foundation. Seal around any openings in the walls, especially around utility pipes and vents. Use weather stripping for gaps in doors and windows.
  4. Don’t Forget Outside. Remove debris from around your home. Keep your yard mowed and weeded. Trim shrubbery away from the sides of your home. Keep woodpiles away from your home.
  5. Use Your Pets. Cats and even some dogs will hunt rodents. Use them as a ready made form of pest control.
  6. Use Traps. There is never just one moue or rat so it is best to use several traps at a time. It is also a good idea to use different types of traps. Use whatever food the pests have been feeding on as bait in your traps. Place traps perpendicular to the walls and near where you have seen signs of their presence.
  7. Call The Pros. If you suspect a mouse or rat problem in your home, contact a pest control professional. They will be able to evaluate your home, identify what kind of rodent you have, and set you up with a comprehensive treatment plan.
