    Wintering and overwintering pests

    • Common intruders
      • Rodents
        • Cold weather drives mice and rats to look for warmth, food, and nesting sites in homes and businesses.
      • Cockroaches
        • Cockroaches are cold-sensitive and struggle to survive outdoors, so they move inside for heat, moisture, and food sources.
      • Spiders
        • While most spiders slow down in the winter, many species seek quiet, undisturbed indoor spaces to escape the cold.
      • Wildlife seeking shelter
        • Colder months drive animals like squirrels, raccoons, and bats into attics, crawl spaces, and chimneys for warmth and safety.
    • Prevention focus
      • Sealing entry points
        • Small gaps around doors, windows, pipes, and foundations make easy entryways for pests. Sealing cracks and openings helps keep rodents, insects, and wildlife from intruding.
      • Maintaining crawlspaces and basements
        • These non-living spaces attract pests looking for warmth and shelter. Proper maintenance helps keep pests from moving in.

  • March – April

    Swarm and reactivation season

    • Common intruders
      • Termites (swarming)
        • Warmer spring weather and moisture trigger termite swarms around homes and businesses.
      • Ants
        • Spring rain can flood colonies, pushing ants indoors in search of dry shelter.
      • Cockroaches
        • Spring brings rising temperatures and moisture—ideal conditions for roaches to become more active and start reproducing.
      • Early mosquitoes
        • Spring rain creates standing water around homes, allowing mosquitoes to hatch and gather in yards, gutters, and shaded areas.
    • Prevention focus
      • Termite inspections
        • Regular inspections catch termite activity early, letting you act before the termites do structural damage (or stop them in their tracks!)
      • Exterior perimeter treatments
        • Treating the exterior of your home creates a protective barrier that deters ants and other pests from entering, reducing the risk of infestations.

  • May – June

    Breeding and population expansion

    • Common intruders
      • Mosquitoes
        • Spring rain and rising summer temperatures leave behind standing water, creating the perfect breeding ground for mosquitoes.
      • Ticks
        • Rapid spring growth leads to tall grass, brush, and wooded edges—perfect places for ticks to hide and latch onto passing hosts.
      • Fleas
        • As temperatures rise, flea eggs and larvae develop more rapidly, resulting in increased infestations in homes and on pets.
      • Ants
        • Spring warmth and rain support the growth of ant colonies, widening their foraging area in search of food and water, often into your home.
    • Prevention focus
      • Mosquito reduction
        • Reducing water sources, barrier treatments, or applying larvicides or repellents helps to eliminate mosquitoes before they become a problem.
      • Tick and flea treatments
        • Treatments target ticks and fleas at their source. By eliminating them before they reach your pets or home, you reduce the risk of being bitten.

  • July – August

    Peak pest season

    • Common intruders
      • Cockroaches
        • Warm, humid conditions speed up cockroach reproduction. They thrive in kitchens, bathrooms, and damp areas both outside and inside homes.
      • Mosquitoes
        • Summer rain and heat create standing water, allowing mosquito eggs to hatch quickly.
      • Flies
        • Flies multiply rapidly in summer due to warm temperatures and accessible food sources like trash, compost, and pet waste.
      • Stinging insects
        • Warm weather boosts activity and colony growth. Stinging insects forage for food and build or expand nests in sheltered areas near homes.
    • Prevention focus
      • Ongoing service plans
        • Summer heat and humidity accelerate pest activity and reproduction. Regular pest control keeps infestations in check, preventing bugs and other insects from taking over.
      • Indoor sanitation and humidity control
        • Warm, humid conditions make homes more inviting to pests. Maintaining cleanliness and controlling indoor and outdoor moisture removes food and water sources, making it harder for pests to thrive.

  • September – October

    Fall migration season

    • Common intruders
      • Rodents
        • As temperatures start to drop, mice and rats seek warmth, food, and shelter, making homes and businesses prime targets.
      • Cockroaches
        • Cockroaches move indoors for warmth and consistent food sources as outdoor conditions cool.
      • Spiders
        • Spiders follow other pests inside, seeking prey and shelter from colder temperatures.
      • Wildlife
        • Animals like bats are looking to migrate and find suitable hibernation sites. Other animals like squirrels, raccoons, and opossums are looking for easy entry, too.
    • Prevention focus
      • Exclusion work
        • Sealing cracks, gaps, and other entry points prevents pests like wildlife and crawling pests from getting inside your home or business.
      • Rodent control
        • Addressing rodent activity early stops mice and rats from establishing nests inside your space, reducing the risk of infestations, damage, and contamination.

  • November – December

    Indoor invasion season

    • Common intruders
      • Rodents
        • Cold temperatures send rodents searching for cozy places to nest—often inside homes and businesses.
      • Cockroaches
        • Cockroaches are sensitive to cold and move indoors to find heat, water, and food, often hiding in kitchens, bathrooms, and basements.
      • Wildlife
        • Animals like squirrels, raccoons, and opossums seek protected spaces to stay warm, such as attics, crawl spaces, and chimneys.
      • Overwintering insects
        • Some insects enter homes solely to survive the winter, hunkering down just waiting for spring to arrive.
    • Prevention focus
      • Interior monitoring
        • Interior monitoring targets problem areas, allowing you to detect rodent activity early and prevent populations from growing in your home or business.
      • Inspecting the attic, crawlspace, and garage
        • Inspecting these areas helps detect unwanted activity early. It also uncovers gaps, cracks, and openings so you can seal them to prevent further intrusion.

Pest seasonality FAQs

  • Is there a pest control off-season in North Carolina?

    Unfortunately, no. There isn’t a true off-season for pest control in North Carolina. While certain pests are more active during specific times of the year, many species, including rodents, cockroaches, and other insects, remain active indoors during cooler months. Year-round pest control is the most effective way to protect your home or business and prevent infestations from occurring.

  • When should I start mosquito control?

    In North Carolina, mosquito control should begin early in the spring, as soon as temperatures rise and standing water starts to appear. Mosquito eggs can hatch quickly in warm, wet conditions, so early prevention helps keep populations under control before they become a burden.

  • Do I need pest control year-round in the Triad?

    Yes. In the Triad, pests are active throughout the year. Seasonal changes may shift where or how they appear, but without year-round protection, infestations can develop quickly. Professional, year-round pest control helps prevent problems before they start, keeping your home or business safe and pest-free throughout every season.

  • What are the signs of an infestation?

    Pests are good at staying hidden, but they usually leave clues. Catching the signs early can prevent bigger (and more expensive) problems later. Here’s what to look for:

    • Small pellets, dark specks, or smear marks near baseboards, cabinets, attics, or garages
    • Scratching, scurrying, or chewing sounds in walls, ceilings, or crawl spaces
    • Gnawed wires, wood, or insulation, holes in drywall, hollow-sounding wood, live or dead bugs, or unusual odors
  • How much does pest control cost?

    Pest control pricing varies based on factors like the size of your property and the severity of the infestation. No matter your needs, we make protection affordable with ongoing specials and exclusive discounts, so you can get the Triad’s most trusted pest control services without stretching your budget.
