Every season brings new weather patterns—and new pest problems. If you've ever wondered why you start seeing ants in spring, wasps in the summer, or rodents scrambling indoors as temperatures drop, it’s no coincidence. Pest behavior follows seasonal cycles, just like ours.

At Thomas Pest Services, we know that timing is everything when it comes to preventing infestations. That’s why our Complete Care Program is built around seasonal pest patterns, with six carefully timed visits each year to protect your home from what’s active now—and what’s coming next.

Let’s break down how seasonal shifts affect pest pressure, and what you can do to stay ahead.

Why Timing Matters: Seasonality & Pest Behavior

Pests are a lot like people:

• They want to be inside when it’s cold.
• They’re most active when it’s warm.
• They move around when the weather changes.

In the Northeast, March might still feel like winter—or we could see a warm spell that kicks off early pest activity. These temperature shifts drive infestations, often before homeowners notice a single bug.

That’s why a proactive approach works best. With our Complete Care Program, our technicians visit your home every other month, aligning services to the season. We're treating now, prepping for the next wave, and adjusting based on unpredictable weather.

You can’t always predict the forecast—but you can count on protection that works year-round.

Here’s a breakdown of what pests to watch for—and when to act.

Winter: Stop Pests Before They Settle In

Common Invaders:
Rodents such as mice and rats; spiders, cluster flies and squirrels (not included in the Complete Care program but we can diagnose their activity)

Rodents only need a hole the size of a dime to enter. Once inside, they can multiply fast and stay hidden for months.

Complete Care Focus:
We focus on inspections, sealing entry points, and rodent monitoring. We also apply dusting products to the exterior—a preventive treatment that stops early spring insects from getting in as they emerge.

Spring: Cut Off Colonies Before They Grow

Common Invaders:
Ants, termites, carpenter bees (not directly covered but treatments help), wasps, early rodent activity.

Warmer temps wake up wood-destroying insects and colony-builders. This is your chance to intercept them before they’re active.

Complete Care Focus:
We apply targeted perimeter treatments, place baits, and inspect for termite activity. Our goal is to address current concerns while prepping for summer spikes.

Summer: Block Biters & Stingers at Peak Activity

Common Invaders:
Stinging insects like wasps, hornets, yellow jackets; mosquitoes and ticks (not covered, but we offer helpful tips and other treatments).

This is prime time for painful stings and airborne invaders—especially in outdoor spaces.

Complete Care Focus:
We conduct thorough inspections, treat visible nests, and apply products to help prevent new nests from forming. We also advise on how to reduce mosquito and tick habitats by managing standing water and overgrown grass.

Fall: Keep Overwintering Pests Out

Common Invaders:
Stink bugs, boxelder bugs, cluster flies, spiders, rodents, squirrels.

Fall is your last chance to block pests from coming inside to hibernate. If you wait too long, they’ll be with you all winter—and pop back up in spring.

Complete Care Focus:
We conduct a major exterior inspection, seal entry points, and apply a final liquid barrier treatment before the cold sets in. This stops overwintering pests before they get comfortable.

Smart Home Habits for Year-Round Prevention

Professional treatments work best when paired with simple home routines. Here are a few examples of habits that support pest control throughout the year:

• Clean & Seal: Wipe kitchen counters nightly and seal open food.
• Moisture Control: Fix leaks and keep basements dry.
• Yard Care: Mow grass, remove standing water, and store firewood away from your home.
• Storage Smarts: Use plastic bins instead of cardboard for seasonal décor and clothing.
• Drop Zones: Designate a backpack/shoe area to avoid bringing pests inside.

We don’t just treat—we educate. During each visit, we’ll help you spot vulnerabilities and offer practical, low-stress ways to make your home less inviting to pests.

Protect Every Season with the Complete Care Program

Our Complete Care Program offers:

• Six seasonal service visits every year
• Timely treatments designed for active and upcoming pests
• Preventative applications and inspections
• Rodent monitoring and proofing
• Expert insight and maintenance recommendations
• Peace of mind for homeowners who want pest control that runs on autopilot
  
  

It’s a smarter, more efficient alternative to one-time treatments. Products naturally degrade over time, and weather shifts can create new pest pressures overnight. A maintenance plan gives you coverage you can count on—even when life gets busy.

At Thomas Pest Services, we believe in relationship-based pest control—so you always know who’s coming to your home, and what to expect.

Don’t Wait Until It’s Too Late

With pests, what you can’t see can still be a problem. And by the time you spot them, they’ve likely already made themselves at home.

Take the proactive route.
