Pest Control in Pasco, WA

Pasco is one of the driest and hottest places we serve. July highs average about 92 degrees, and July is also the warmest month. January lows average around 28, and December tends to be the coldest month. Annual precipitation comes to only about 8 inches, and January is usually the wettest month at roughly 1 inch. About 55 days a year reach 90 degrees or higher, and about 112 nights fall to freezing or below.

All of these come from 1991-2020 NOAA climate normals recorded at a nearby weather station. They are a general guide, not a forecast, and any given year can run hotter, colder or wetter. With rain so rare, the water that people supply becomes the center of pest activity. Sprinkler lines, hose connections, pet dishes and air conditioner drip lines all attract insects that would otherwise stay away from a house.

For Pasco, we advise starting in early spring with an exterior treatment and a quick walk around the property to fix any leak. As temperatures climb, keep trash lids closed, empty containers and look up under eaves for new wasp nests. In early fall, before nights turn cold, close gaps around doors, garage seals and utility openings. Through winter, check attics, garages and storage areas for signs of mice.
