As monsoon season creeps in across Southern Arizona, homeowners from Tucson to Phoenix start to notice the same thing: more ants, scorpions, and roaches creeping inside. What gives?

At Northwest Exterminating, we’ve seen it year after year—when the desert heat collides with rising humidity, pest activity spikes. Knowing why this happens (and what to do about it) can help you stay one step ahead of pests.

What’s Going On With the Bugs?

Pests are just like us in the summer—they’re looking for a break from the heat and a place to hydrate. The shift from dry to wet weather kicks pest instincts into high gear, making your home a prime target for shelter and breeding.

Ants

As humidity rises, odorous house ants and other species become more active, expanding their colonies and foraging for food and water. Tiny cracks in your walls or foundation are all it takes for them to make themselves at home in your kitchen or bathroom.

Scorpions

Arizona bark scorpions don’t love the heat as much as you’d think. As temperatures climb, they sneak inside looking for cool, moist hiding spots—often in laundry rooms, garages, or under bathroom sinks.

Roaches

Roaches love the muggy air that comes with monsoon season. With more moisture in and around your home, they find dark, damp spaces—like basements, under sinks, or behind appliances—to nest and multiply.

Easy Ways to Prep Your Home Before The Rain Hits

The best defense is a good offense. Here’s how to make your home less inviting to pests during this seasonal shift:

  • Seal up entry points: Caulk cracks, plug up weep holes, and weather-strip doors and windows.
  • Keep it clean: Regularly wipe down surfaces and don’t leave food or standing water out.
  • Dry things out: Repair leaks, clear gutters, and consider a dehumidifier in musty areas.
  • Tidy the yard: Remove piles of leaves, firewood, and debris where pests like to hang out.
