Fall Prep: Easy Ways to Keep Pests Out

TAYLOR LAMBERT September 17, 2025

Over the past few weeks, invasive mosquitoes and an insect called the “kissing bug” have been spreading across California. These pests aren’t just annoying; they can transmit diseases like dengue, Zika, yellow fever, and Chagas. As the weather cools and fall sets in, bugs start looking for warmth and shelter, which often means moving indoors. Whether you own or rent, a little prevention now can save you a lot of trouble later.

Seal Cracks and Gaps

Start by sealing up any cracks or gaps around your home. Take a quick walk inside and outside, and note where you see openings. A little caulk or weather stripping around doors, windows, and baseboards can make a big difference. Even small cracks and holes can be patched easily with spackling. Not only does this cut down on the chance of an infestation, but it also boosts your home’s energy efficiency and helps protect against water leaks.

Eliminate Moisture

Moisture is another big attraction for pests. Bugs thrive in damp environments, so check under sinks, around pipes, and in crawl spaces for leaks or standing water. Keeping things dry discourages insects from settling in and also helps prevent mold and mildew.

Declutter and Keep it Clean

Clutter is another hidden invitation. Old documents, cardboard boxes, and unused belongings give pests dark and undisturbed places to hide. Clear out what you don’t need, and while you’re at it, check your pantry for expired or tampered food.

A little prep work now can go a long way in keeping your home bug-free through the colder months. With a few weeks of sunny weather left, it’s the perfect time to get started.
