Pest Control in Wisconsin

Weather differs from one part of Wisconsin to another. Across the communities we serve, July highs average roughly 81°F, ranging from about 76 to 86°F, while January lows average near 10°F. A typical year brings roughly 35 inches of precipitation, from about 25 inches in the driest of our cities to about 40 in the wettest, and about 152 nights a year at or below freezing. These figures are climate averages from local weather records for 201 cities, so they describe the pattern, not a forecast.

Long, hard winters shape the pest calendar here. Insects and rodents do not simply disappear when the cold arrives; they move into wall voids, attics and crawl spaces where it stays warm. That is why the weeks before the first serious freeze are the best time to seal cracks, replace worn door sweeps and screen vents, well before animals start looking for shelter.

Spring and summer bring a short, intense burst of activity. Warm, humid stretches speed up ant colonies and mosquito breeding, so early-season treatment and draining standing water accomplish far more than reacting once a nest or swarm is already established. Matching your extermination and prevention work to the seasons keeps small problems small and protects the work you have already done.
