Pest Control in Klamath Falls, OR

Klamath Falls is dry and cold compared with much of Oregon. July highs average about 86 degrees, July is also the warmest month, and about 18 days a year reach 90 or higher. January lows average around 22, and December is the coldest month. Precipitation is light, at only about 11 inches a year, with December the wettest month at about 1.8 inches, and the snowfall figure averages out to essentially zero. The number that stands out is roughly 184 nights a year at or below freezing. These are 1991-2020 NOAA climate normals from a nearby weather station, so use them as a guide, not a forecast.

That many freezing nights, about half the year, changes the pest season. Insects that survive by hiding indoors, such as spiders, boxelder bugs and stink bugs, start moving toward foundations in early autumn, and rodents follow as the first frosts arrive. Because the ground stays cold for months, there is less pressure from termites than in wetter places, but heated buildings still create warm pockets where pests are active all winter.

For a Klamath Falls home, the calendar runs backward from the first hard freeze. Seal gaps and check door sweeps and vents in early fall, keep firewood away from the house, and look for droppings and chew marks in attics and garages during winter. In spring, deal with ants and wasps before nests grow, and use the dry summer months to repair leaks and clear brush along the foundation.
