Pest Control in South Dakota

Weather differs from one part of South Dakota to another. Across the communities we serve, July highs average roughly 85°F, ranging from about 81 to 88°F, while January lows average near 8°F. A typical year brings roughly 24 inches of precipitation, from about 17 inches in the driest of our cities to about 30 in the wettest, and about 163 nights a year at or below freezing. These figures are climate averages from local weather records for 18 cities, so they describe the pattern, not a forecast.

Hard winters send boxelder bugs, spiders and rodents into wall voids and attics, so the most valuable work happens before the first freeze. Fall is the time to caulk gaps, install door sweeps, screen vents and move firewood and clutter away from the house. Rodents in particular go looking for warmth as soon as temperatures dip, and a small opening is all they need to get inside.

Warm spells in spring bring insects out of hiding fast, and a dry climate does not stop mosquitoes after a wet week. Treating the outside of the building early in the season keeps ants and wasps from getting a foothold, which saves you from a larger extermination job later. Spring and summer treatments work best when they follow the first warm days, before colonies are large enough to be hard to control.
