July is peak pest month in the Treasure Valley, and it's showing.
Wasp nests that were 50 workers in June are sitting at 800+ right now. Black widows are at their annual July peak, mostly in garages and irrigation boxes. And mosquitoes are hitting new broods every week off the Boise irrigation cycle.
Quick tip: if you see wasps flying in and out of a hole in the ground, don't touch it. That's a yellow jacket nest and in July those get ugly fast.
We just updated our summer guide with exactly what's spiking in Boise right now:

Mid-summer 2026 is here and Treasure Valley pest pressure has hit peak. Wasp colonies are pushing toward 5,000 workers, black widows are at annual peak, mosquito breeding is locked into the irrigation cycle, and crickets and voles are spiking near foothills and farmland.
