Pioneer Pest offers tips homeowners can use to keep rodents away this winter.

We know it’s early to start preparing for fall, but when it comes to rodents, now is a perfect time. Because as soon as the temperature drops, rodents like mice, roof rats, and Norway rats will start getting ready to hunker down for winter.

When looking for a place to live, rodents will look for access to nest-building materials, a dependable food source, and somewhere that’s warm and safe. Unfortunately, this can sometimes include our homes. So what can you do to prevent an infestation? Here are 10 tips you can do now to keep rodents away this winter.

  1. Seal exterior doors: repair any damaged doors and install door sweeps to the bottom. Roof rats, Norway rats, and mice can squeeze easily into small spaces like these. Keep in mind your garage doors too.
  2. Add screens to vents and chimneys: installing mesh to these areas will prevent them from gaining access to the inside of your home. Always verify your local building code requirements before installing screening over any vent or chimney. Not only can rodents squeeze into small spaces, but they can also scale siding and chimneys.
  3. Seal potential entry points: you can use caulk/spray foam and steel wool to seal holes rodents may use, but many times they will chew right through it. Sealing entry points should be done using proper materials such as metal flashing or rodent excluder in conjunction with caulking or spray foam.
  4. Seal basement and windows: replace any old weather stripping or mortar around your basement foundation, windows, and window sills.
  5. Seal pipes: fix, cap or replace any broken sewer, drain or exhaust pipes you have. Rodents may use these pipes to get inside your home. Rats are great swimmers too.
  6. Properly store food and maintain cleanliness: leaving food out can cause a serious infestation. Store food in airtight containers and regularly throw out your garbage.
  7. Ventilate: keep the crawlspaces, basements, and attics of your home dry and well ventilated.
  8. Move firewood: if you have stored firewood, keep the pile at least 20 feet away from your home. Even better if you can keep the wood elevated.
  9. Inspect vehicles: regularly check under the hood of your vehicles and look for signs a rodent has been there. Things like gnawed wires, rodent nests, and rat or mouse droppings — which are typically dark in color and shaped similar to a piece of rice.
  10. Inspect Items: Another thing you may want to inspect are packages, bags, and anything else you are bringing into your home, especially if they’ve been outside for quite some time.
