Spring brings fresh air, blooming gardens—and unfortunately, a rise in flying pests. As temperatures climb and rain becomes more frequent, the excess moisture around your home can create the perfect conditions for unwanted bugs to move in. It’s quite common to see in influx of flying bugs in spring.

Spotting winged insects indoors might seem like a small nuisance, but it could indicate something more serious—like termites. Only about one in three homeowners recognize the early signs of an infestation. Termites become active in the spring, with reproductive members of the colony growing wings and swarming in search of new nesting sites. Catching this activity early is key to preventing costly damage.

Why Rainy Weather Invites Termites (and Other Pests)

Warmer weather and increased rainfall can kickstart termite mating season. Eastern subterranean termites, common in the Midwest and beyond, emerge in daylight to mate and start new colonies. If you find discarded wings near windows or doors, it may be a sign that termites have already made themselves at home nearby—or inside.

U.S. Cities on the Public Health Pest Index Spring 2025

Cities like Seattle, Denver, Cleveland, San Antonio, and Boston are expected to see a surge in pest activity this season. Rodents, mosquitoes, cockroaches, and ticks are more than just a nuisance—they pose real health risks, from spreading bacteria to triggering allergies and transmitting serious diseases.

Pests That Thrive in Moisture-Rich Environments

Rainfall brings out all kinds of bugs. Most are just nuisances, but some are a bit more of a concern as a homeowner. The Bug Barometer below gives us a head’s up on the types of insects we can expect to see surge this spring and summer. 

Eastern Subterranean Termites

In the Midwest, the eastern subterranean termite is one of the most destructive moisture-attracted flying insects. These wood-damaging pests are active across much of the U.S. and can cause major structural issues over time. Moisture is their lifeline, so keeping areas dry—especially where wood meets soil—is one of the best defenses.

These days, getting rid of termites doesn’t necessarily mean injecting gallons of products into the ground or digging up a yard. We stand by a completely chemical free solution called Sentricon. It works like a charm to eliminate and prevent termites, taking your home off the menu to these wood destroyers.

If it has been longer than 2 years since you had a termite inspection on your house, get on our schedule before it’s too late.

Carpenter Ants

Attracted to damp, fungus-covered wood, carpenter ants don’t eat wood but tunnel through it to build nests. If you notice sawdust-like debris or winged ants, it’s time to investigate further.

Rodents and Ticks

Rats, mice and their parasites like ticks thrive in damp, cluttered environments. Rodents can carry bacteria like Salmonella and E. coli, while ticks are known vectors of Lyme disease and other illnesses. Staying on top of yard maintenance and sealing entry points can help keep them out.

Centipedes and Millipedes

These multi-legged crawlers are harmless but unsettling. They typically show up in damp areas like basements and bathrooms, and their presence usually points to an underlying moisture issue.

Earwigs

Drawn to humid spots, earwigs may turn up in bathrooms, under potted plants, or in basements. They’re not dangerous, but they can damage houseplants and become a real nuisance indoors.

Simple Steps to Keep Your Home Dry and Pest-Free

A moisture-free home is one of the best deterrents for spring pests. Here’s what you can do:

• Fix leaky pipes or faucets promptly.

• Use dehumidifiers in basements or bathrooms.

• Keep firewood, mulch, and wood piles away from the home’s foundation.

• Seal gaps and cracks around doors, windows, and baseboards.

• Regularly check for water-damaged or decaying wood.

• After heavy storms, inspect your home for signs of water intrusion or damage.

When to Bring in a Professional

DIY methods may offer a quick fix, but they often miss the underlying moisture issues that pests rely on. A professional inspection is the best way to catch hidden infestations early—especially if your area has experienced recent flooding or severe weather.

An annual inspection is a smart investment that can help prevent major damage and give you peace of mind. Contact us to get on our schedule for peace of mind.
