When the first hard freeze hits Prescott and the overnight lows drop below 32, it’s tempting to assume the bugs have packed up and left for the season. Down in Phoenix, that assumption would be wrong all year long. Up here at a mile high, it’s only half right. Prescott’s real winters do slow some pests down, but they push plenty of others straight toward the warmest place around, which is the inside of your home. Here’s what actually happens when the temperature drops.
Yes, some pests really do slow down
Let’s give the cold its due. Most insects are cold-blooded, so when temperatures fall, their bodies slow down, and they stop developing. Some die off outdoors, and many that survive go dormant, tucked away and inactive until spring. That’s why your yard feels quieter in December, and why you see far fewer flying and crawling bugs than you did back in August.
So the instinct isn’t totally wrong. A Prescott winter genuinely thins out a lot of the warm-weather crowd.
The catch: the cold sends others indoors
Here’s where the myth falls apart. Not every pest gives up when it gets cold. A good number of them do exactly what you do, which is head somewhere warm.
According to the University of Arizona Cooperative Extension, as the weather cools, rodents move indoors in search of warmth, shelter, food, and water, and certain insects look for dry, protected cracks to wait out the winter. To those pests, your heated Prescott home isn’t a deterrent. It’s the best real estate in the neighborhood.
Who tends to move in for a Prescott winter
A few usual suspects account for most of the cold-weather calls we get:
- Rodents are the big one. Mice, roof rats, and pack rats squeeze through surprisingly small gaps to nest in attics, garages, and wall voids, where they chew wiring and insulation and leave droppings behind.
- Overwintering insects like boxelder bugs, stink bugs, and seed bugs slip into cracks and crevices to wait out the cold, then wander back out on warm days to confuse everyone.
- Spiders don’t so much move in as become more noticeable, since the ones already tucked into quiet corners have fewer places to hide once the garage clutter comes out.
- Fleas can hitch a ride indoors on a rodent, then thrive in your warm house and find your pets.
Why fall is the time to deal with it
The move indoors mostly happens in a narrow window, as the nights turn cold but before winter fully sets in. That timing is worth knowing, because it is far easier to keep pests out than to evict them once they’ve settled into your walls.
A mouse or a cluster of stink bugs that slips in during a November cold snap can spend the entire winter comfortable and hidden. Sealing the house up before that happens is the difference between a quiet winter and a spring surprise.
How to keep the winter crowd out
You can close off most of the invitations with a weekend of work:
- Seal the gaps and cracks around your foundation, doors, windows, pipes, and vents, since rodents and insects both use them to get inside.
- Move firewood, brush, and clutter away from the house, because stacked wood against a wall is a staging area for pests.
- Check that your weatherstripping and door sweeps still seal tightly, paying special attention to the garage.
- Store pantry and pet food in sealed containers, and keep trash in bins with lids that latch.
- Cut back branches and dense plants touching the house, which give climbing pests a bridge to your roofline.
When to call Patriot
If you’re already hearing scratching in the walls, finding droppings, or sweeping up the same bugs every few days, the winter crowd has already moved in, and that’s worth handling before it settles in for the season. If you’d rather get ahead of it, a fall inspection is the easiest way to find the gaps you can’t see.
