Springtime Pest Emergence in NC: What Homeowners Need to Know
Spring in North Carolina is a beautiful time of year. The trees bloom, flowers blossom, and temperatures finally rise after a chilly winter. But while you’re enjoying the outdoors or opening windows to let in the fresh air, pests are also making their comeback. Warmer temperatures, increased moisture, and longer daylight hours create the perfect conditions for insects and rodents to emerge—and often, to invade your home.
Understanding which pests to look out for and why they become so active this time of year can help you stay a step ahead. In this blog, we’ll explore the most common springtime pests in North Carolina, why they thrive in the spring, and what proactive steps you can take to keep them out.
Common Spring Pests in North Carolina
Ants
In spring, ant activity increases as colonies become more active. The warm weather signals foragers to leave the nest in search of food and water. In North Carolina, common culprits include:
- Odorous house ants – Known for the rotten coconut smell they emit when crushed.
- Carpenter ants – Large black ants that nest in wood and can cause structural damage.
- Argentine ants – Often invade in large numbers, forming massive colonies.
Where you’ll see them: Kitchens, bathrooms, patios, and along baseboards.
What to do: Keep countertops crumb-free, seal pantry items, and address any moisture issues like leaky pipes or damp wood.
Termites
North Carolina is considered a high-risk area for termite activity—particularly Eastern subterranean termites, which thrive in our humid climate.
Spring marks the swarming season for North Carolina termites, when reproductive termites leave their nests to form new colonies. If you see flying termites around your home or discarded wings near windows, doors, or light fixtures, you may have an infestation.
What’s at risk: Your home’s wooden framework, crawl spaces, decks, and fence posts.
What to do: Schedule a professional termite inspection, check for mud tubes along your foundation, and keep wood piles and mulch away from your home's perimeter. Learn how to prepare your home for termite season.
Mosquitoes
Spring rains and warming temperatures signal the start of mosquito breeding season. Mosquitoes lay eggs in standing water, which can collect in birdbaths, clogged gutters, plant saucers, and even bottle caps. We are continuing to see record-breaking mosquito seasons in the Triangle.
In North Carolina, these pests are more than a nuisance—mosquitoes can carry diseases such as:
- West Nile Virus
- Eastern Equine Encephalitis (EEE)
- La Crosse Encephalitis
Where you’ll see them: Around shady yards, near water sources, and during dusk and dawn.
What to do: Remove standing water weekly, use mosquito dunks in birdbaths, and consider professional mosquito yard treatments if the issue becomes severe. Check out other ways to keep mosquitoes away.
Wasps & Bees
Spring is prime nest-building season for both wasps and bees. Common springtime species in North Carolina include:
- Paper wasps – Build umbrella-shaped nests under eaves or decking.
- Yellowjackets – Often nest in the ground or wall voids and can be very aggressive.
- Honeybees – Beneficial pollinators but may swarm during the spring.
While bees are protected and beneficial, wasps can become territorial and dangerous if nests are built near living areas.
What to do: Inspect eaves, sheds, and attics early in the season. If you see an active nest forming, it’s best to call a professional before it becomes a larger hazard.

Why Spring Brings More Pests in NC
Several environmental factors contribute to the surge in pest activity during spring in North Carolina:
- Rainfall: Heavy spring rains create moist soil and standing water, which are perfect for breeding pests like mosquitoes, ants, and termites.
- Rising Temperatures:
- As the temperature climbs above 60°F, insects come out of dormancy or hibernation and begin searching for food, water, and mates.
- Abundant Food Sources:
- Springtime means barbecues, picnics, blooming flowers, and more outdoor trash. All of this attracts foraging insects looking to establish new colonies.
- More Human Activity: More time outdoors means doors and windows are left open longer, giving pests easier access to your home.
Prevention Tips: Stop Pests Before They Start
To stay ahead of pest problems, early-season pest-proofing is key. Here are several proactive steps homeowners can take:
- Seal cracks and entry points around doors, windows, and the foundation.
- Repair leaky faucets and eliminate standing water around the yard to reduce mosquito breeding sites.
- Keep gutters clean and ensure proper drainage to prevent moisture buildup.
- Store firewood and mulch away from the foundation to discourage termite activity.
- Inspect and clean outdoor areas like decks, patios, and sheds regularly for early signs of nests or infestations.
- Schedule a professional pest inspection to catch problems before they grow.
