3 Steps to Keep Rodents & Bugs Out This Winter

Changing leaves indicate colder weather coming on, when bugs & rodents like to come inside.


As fall approaches, cooler temperatures drive rodents and bugs inside your home, looking for a place to survive the winter. Both need food and warmth, and for rodents, nesting materials. Rodents serve a place in the ecosystem, but when they enter our homes they can carry disease and wreck havoc on electrical wiring. This can create a fire hazard. Here are 3 simple steps to keep them from coming inside and living in your home.


1) Deny Them Access

It’s all about “Denial”. Friends, we all know a little something about that! The kind of denial we’re talking about here is access denial, closing off the common access points rodents and bugs use to enter your home. Many of these things you can do yourself with a caulking gun, some hardware cloth, steel wool,  a drill and possibly a can of spray foam.

Let’s start with an easy to fix, but often overlooked access point: door sweeps.

Worn door sweeps leave gaps small rodents and bugs can get in through. If you can see light coming through your door sweeps, they need to be replaced or adjusted. It’s a simple, non-toxic, long-term solution to a common problem.


Common access points are around plumbing, gas lines and electrical conduit.


Some caulk and hardware cloth closed off the gap around this gas line.


Steel wool and caulking sealed up the gap around this toilet water supply line.


Updated electrical left a hole in the bird block in the picture above. A little steel wool stuffed in the hole and caulking over it is a simple way to close up the hole. The steel wool gives the caulking something thing stick to and it deters mice if they chew through the caulking. Caulking the hole over and then installing a small piece of 1/4” hardware cloth (wire mesh)  over the hole would also work.


Steel wool and caulking would close the gap around this insulated copper A/C line going in the house.


2) Deny Them Nesting Material 

Keep rodents out of your crawl space!  This will deny them access to insulation, a favorite nesting material. Check your crawl space door, plumbing lines, gas lines, and HVAC lines going into the crawl space to ensure there are no gaps bigger than a dime, (for mice that’s all they need). Check vents and ensure that all screening is intact and in place.


Rodents have pushed through the vent screening and gained access to the crawl space.


If screening is compromised or missing, replace screening with 1/4” hardware cloth.


3) Deny Them Food

Make sure you store any pet food in rodent-proof containers. If you feed your pets outdoors, only feed them what they can eat in a day. Food left overnight, when rodents are active, encourages them to stick around your property. Other food sources to pay attention to are bird seeds, fruit falling on the ground, etc. Do what you can to keep these food items picked up.
