Pre-Winter Rodent Prevention in New Jersey Homes

The easiest rodent problem to deal with is the one that doesn’t happen. In New Jersey, the weeks of fall are the window where you have your best chance to prevent rodent problems. To help you do that, we’ll share tips on Allendale rodent prevention so you can enjoy the underrated peace of not hearing mice in your walls in January.
First, it’s important to understand that once you start seeing mice and rats, or even evidence of their activity, you probably have an infestation. They’re sneaky. They’re actively trying to avoid being seen by you. So by the time you do see them, that’s a professional problem because they’re probably established in your wall voids or attic.
Fall is the Perfect Time for Allendale Rodent Prevention
Rodents move indoors as the weather cools, typically from October into early winter, searching for warmth and a reliable food source. If your home is sealed and unappealing before that push begins, most of them move on to easier targets. If you seal up gaps in the fall, an infestation will have a much harder time getting established. If you seal them up in January, you might even be trapping rodents in.
Start on the outside of the house. Mice can slip through a gap the size of a dime, so look closely at the small openings: gaps where pipes, cables, and gas lines pass through the wall, cracks in the foundation, the space under the garage door, and worn weatherstripping under exterior doors. You can stuff smaller gaps with copper mesh or steel wool. Then seal with caulk. As for vents, cover those with hardware cloth. If you have worn door sweeps, replace them.
Rodents can chew through foam and plastic, so make sure you use materials they cannot easily gnaw.
Make Your Home Less Attractive to Rodents
Sealing your home helps with Allendale rodent control because it reduces access. But it also helps to reduce the things that make your home an inviting place to attempt to access. To do this, store pantry goods and pet food in sealed containers. You want your counters and floors to be free of crumbs. Rodents also have a bad habit of going after trash and birdseed, so keep tight lids on both.
Outside, move firewood, leaf piles, and debris away from the foundation, trim back shrubs and tree limbs that touch the house, and clear clutter from the garage and basement where rodents like to nest.
Pre-winter rodent-proofing is not a one-time project. Seals wear down and new gaps open. With every fall comes a new push by rodents with nothing to lose. So make sure that you conduct an inspection of your home every fall. Or, better yet, have an Allendale rodent control professional do it for you. They tend to find all the places that homeowners don’t know to check thanks to the pattern recognition that comes with doing the job day in, day out.
