A Simple Fall Pest Check for Your Home
When the weather cools down, I start thinking about all the little home projects I meant to finish before winter. Checking for pests isn’t the most exciting one, but it belongs on the list—especially if you’d rather deal with a loose door sweep now than discover unwanted visitors later.
You don’t have to know the name of every bug in your yard or spray the entire house to do a useful fall check. Set aside a little time to walk around your home, look for easy entry points, and clean up the places pests might find food, water, or shelter.
Start at the doors and windows
Close each exterior door and look for light showing through around the edges or underneath. Check that door sweeps are still in place and that garage doors close snugly. Look over window screens for tears or loose frames, particularly on windows you’ve been opening during cooler evenings.
If you find a gap, note exactly where it is before buying supplies. A worn door sweep, a damaged screen, and an opening around a pipe need different fixes. For larger holes or anything near wiring or plumbing, it may be worth getting help with the repair.

Walk around the outside of the house
Look along the foundation, near utility lines, and around vents for openings or signs of activity. Move leaves and clutter away from exterior walls so you can actually see what’s going on. Trim back plants that brush against siding or block access to a window.
Take a quick look under the porch, around outdoor storage, and near the trash cans, too. You don’t have to overhaul the yard; you’re looking for places that stay damp or give pests an easy place to hide.
Check for water where it shouldn’t be
Even in fall, water can collect in plant saucers, buckets, toys, and clogged gutters. Empty containers after rain and check for slow leaks at outdoor faucets. Inside, look under sinks and around plumbing for moisture you may have missed.
The EPA’s pest prevention guidance starts with the basics: reduce access to food, water, and shelter, and close off ways pests get inside. Those steps are useful whether or not you’ve noticed a problem yet.
Rethink what’s stored beside the house
Fall is when extra boxes, patio items, and firewood can start piling up. Keep firewood away from the house, check outdoor items before bringing them inside, and avoid leaving bags or cardboard in a damp garage corner. If you store seasonal decorations in bins, look them over when you pull them out.
Watch for signs that need a closer look
Droppings, gnaw marks, damaged screens, repeated pest sightings, or insects appearing in the same place over and over deserve attention. Take a photo of what you see and note where and when you found it. Identifying the pest and its entry point is more helpful than grabbing a treatment product at random.
For a persistent issue—or suspected termites, rodents, or a nest in a hard-to-reach spot—contact a qualified local pest professional. Ask what they found, what they recommend, and what you should do before and after any treatment. If you use a pesticide yourself, follow the product label and keep children and pets away as directed.
If you live in the greater Phoenix area, Green Mango Pest Control is one local company you can look into. Wherever you live, check a company’s service area and credentials before booking; a company that serves Arizona won’t be the right contact for a home in Tennessee.
My quick fall pest check list
- Look for gaps around exterior doors, windows, and the garage.
- Inspect screens, vents, and openings around utility lines.
- Clear leaves and clutter from the foundation.
- Empty standing water and check for leaks.
- Look over firewood, storage bins, and items coming indoors.
- Make a note of repeated sightings or signs of damage.
This is one of those home tasks that’s easy to put off because nothing looks urgent. A short walk around the house now can help you catch the little things before winter—and then you can get back to the much more enjoyable fall projects.
