Pest Control in Spokane Valley, WA

Spokane Valley has a dry climate with distinct seasons. July highs average about 87 degrees, and July is also the warmest month. January lows average around 26, and December tends to be the coldest month.

About 29 days a year reach 90 degrees or higher, and roughly 123 nights a year fall to freezing or below.

These are 1991-2020 NOAA climate normals from a nearby weather station, and they are a guide, not a forecast. The pattern is a real swing between summer heat and winter cold. Hot days speed up insect life cycles, so ant colonies and wasp nests can grow quickly once summer starts. Long stretches of freezing nights then push rodents and overwintering insects into buildings.

A helpful calendar in this area starts in early spring with an exterior treatment and a check of any damp wood. Midsummer is a good time to look for wasp nests and to repair irrigation leaks that bring insects to the foundation. In September, seal gaps around doors, vents and utility lines and clear leaves and debris from against the house. In winter, check attics, garages and basements regularly for signs of rodent activity.
