Homeowners across Centralia feel the pain of this struggle: carpenter ants marching through your kitchen during the finicky month of May, mice nesting in your garage in December. Pest pressure is not seasonal; it’s ongoing here, given the city’s proximity to the Chehalis River and its mix of older neighborhoods and newer developments.
The Pacific Northwest’s climate makes it a year-round paradise for pests, and in Centralia, the mild, wet winters can mean bugs and rodents never entirely leave. With local property data showing that almost 40% of Centralia homes were built before 1980, pests have even more access as foundations age and siding deteriorates.
Reactive treatments could resolve our current situation, but next month we could again face an invasion. Having the right people, such as pointepest.com, who know Centralia inside and out, is everything to keeping your home safe from pests.
January–March: Winter Watch and Rodent Prevention
Winter in Centralia does not freeze out the pests; it drives them inside. During these cold, rainy months, rodents seek warmth in your attics, crawl spaces, and wall voids. Inspect for rodents in January to prevent entry points from being sealed when populations are larger. Check for droppings around insulation and for gnawing on stored items. Now, springtime infestations, when rodents begin to breed in earnest, are prevented by the work of a professional exclusionist.
April–May: Spring Swarm Season for Ants and Termites
Carpenter ants can come out of winter hibernation and infest wood that has been moist for more than a few months. Termites swarm on warm days to find new homes. Preventive barrier treatments around foundations and moisture control assessments offer some of the best outcomes in April and May. Termites alone cause millions of dollars in damage across Washington State each year, and early detection saves thousands of dollars in repair costs.
June–July: Mosquito and Wasp Control in Peak Season
Summer in Centralia has people doing a lot more outside, but the mosquitoes and wasps have the same idea. Lingering June rains support breeding areas next to the Chehalis River corridor and puddles in backyards. Nests of yellow jackets and paper wasps are found in eaves and trees. Timely mosquito treatments by early June and wasp nest removal before peak populations occur in July. Apply regularly, and your backyard barbecues are enjoyable instead of itchy.
August–September: The Late-Summer Pest Crossover
A pest perfect storm in Centralia, thanks to late summer. Afterward, spiders march indoors in search of prey, wasps turn aggressive as their colonies fill, and ants press final foraging salvos before autumn. Hobo spiders are most active in Washington homes during August. Chilly September temperatures push stink bugs into structures. That means you must have strategies in place that target multiple pest types simultaneously to prevent invasions in the fall.
October–November: Fall Invaders Move In
Pests are on the prowl, aggressive as Centralia temps fall and rains increase. Box elder bugs gather on south-facing walls, ladybugs invade attic voids, and shrews, moles, and mice enter homes through 1/4″ holes. October is your last chance for any crack sealing and perimeter treatments before winter hibernation. Fall applications by a professional provide a barrier against the rainy season.
December: Reset for a Pest-Free New Year
December is not only for holiday decorations; it is also your opportunity to evaluate and refresh pest suits. Revisit trouble areas from the previous year with renewed energy. In places like Centralia, where rain collects, check moisture levels in crawl spaces. Get annual inspections to identify emerging issues before they worsen. With summer out, this month allows professionals to treat without time limits.
Why Year-Round Scheduling Works Better Than One-Off Visits
In Centralia, the climate means pest pressure changes but never goes away, so what works in July will not work in January. And problems are caught during vulnerable stages, such as treating termites before they swarm or excluding rodents before breeding season, which helps reduce populations. To address that situation, Pointe Pest Control has preventive programs tailored to what is active on Centralia’s pest calendar, rotating treatments to follow what’s active each month.
