10 Non-Toxic Ways to Pest-Proof Your Home This Season

You do not need a cabinet full of chemicals to keep pests out of your home. In fact, the most effective pest prevention is almost entirely non-toxic — it is about removing what pests want (food, water, and shelter) and blocking how they get in.

Here are ten simple, chemical-free steps every Wisconsin homeowner can take this season.

1. Seal Every Crack and Gap

Pests only need a gap the width of a pencil to get inside. Walk the exterior of your home and seal cracks around the foundation, siding, and where pipes enter with silicone caulk. This is the single most effective non-toxic step you can take — and it is the foundation of our pest exclusion approach.

2. Install Door Sweeps

A gap under an exterior door is an open invitation. Install a door sweep on every exterior door, including the one to your garage. The seal should touch the threshold with no daylight showing through.

3. Fix Leaks Fast

Pests need water as much as food. A dripping pipe under the sink or a slow roof leak is a drinking fountain for ants, roaches, and rodents. Fix leaks the day you notice them, and check under sinks weekly.

4. Keep Food in Sealed Containers

Cardboard boxes and thin plastic bags are no match for ants and mice. Transfer pantry staples — flour, cereal, rice, pet food — into glass or heavy plastic containers with tight lids.

5. Take Out the Trash — and Clean the Bin

A trash bin with a loose lid is a buffet. Use bins with tight-fitting lids, rinse them out monthly, and never let bags sit outside the bin. A splash of vinegar in the bottom repels flies.

6. Declutter the Perimeter

Piles of firewood, leaves, and stored items against your foundation create the dark, sheltered pathways pests love. Keep a 12-inch clear border around your home and store firewood at least 20 feet away.

7. Manage Moisture in the Basement and Crawlspace

A dehumidifier set below 50% humidity makes your basement unattractive to spiders, centipedes, and silverfish. Learn more in our pest education center.

8. Use Natural Repellents

Peppermint oil on cotton balls placed near entry points deters spiders and mice. A line of diatomaceous earth along baseboards is harmless to humans but deadly to crawling insects. These are great first-line, non-toxic options.

9. Clean Up the Kitchen Every Night

A few crumbs on the counter is a feast for ants. Wipe counters, sweep floors, and run the dishwasher before bed. This single habit does more than almost anything else to prevent ants.

10. Keep Gutters Clear

Clogged gutters overflow and saturate the soil around your foundation, drawing pests that love moisture — including termites. Clean gutters twice a year and ensure downspouts direct water well away from the house.
