Why Are There More Bugs When It’s Humid?

If you’ve ever noticed more bugs during humid weather, you’re not alone—and you’re definitely not imagining it. At Getem Services, we see a spike in pest activity during Virginia’s muggy months, especially in the Hampton Roads region. Understanding how humidity fuels bug behavior can help you see how weather impacts infestations—and why professional pest control and moisture control are key to long-term relief.

The Connection Between Humidity and Increased Pest Activity

Humidity doesn’t just make the air feel heavy—it also creates ideal conditions for insects to thrive. Many pests rely on moisture to survive, and others seek out damp environments to nest, reproduce, or feed. In Virginia, especially during late spring and summer, increased humidity levels lead to a visible spike in insect presence both indoors and outdoors.

Moisture encourages pest activity by softening wood, attracting fungal growth, and maintaining water sources in crawlspaces and landscaping. The more moisture present, the more opportunities pests have to settle in.

Which Bugs Are Drawn to Humid Conditions?

Not all pests love the heat and humidity equally, but several species become far more active during damp conditions. In the Hampton Roads area, we frequently respond to increased sightings of moisture-loving insects around this time of year.

Mosquitoes

Mosquitoes are infamous for breeding in standing water. Just a few ounces of water in a clogged gutter, flower pot, or birdbath is enough to support a new generation. Humid weather also extends their activity period, making them more aggressive throughout the day.

Our mosquito control program targets breeding areas and adult populations through seasonal treatments that address both larvae and active mosquitoes.

Termites and Carpenter Ants

These wood-destroying insects are drawn to moisture-damaged wood. High humidity increases the risk of leaks, condensation, and damp wood framing, especially in crawlspaces and around foundations. Subterranean termites rely on moisture to survive and build mud tubes that help them move through dry areas. Carpenter ants are drawn to wood that’s already been softened by moisture, making it easier for them to tunnel and establish nests.

We provide comprehensive termite control with inspection, monitoring, and liquid treatment options. Carpenter ants are covered under our residential pest control services.

Silverfish, Centipedes, and Millipedes

These pests thrive in damp, dark environments like crawlspaces, basements, and under sinks. They’re most active in high humidity, where moisture levels remain consistent. You might notice them crawling along baseboards or bathroom floors after a storm or during humid mornings.

If you’re seeing moisture-loving pests indoors, the problem may be starting below your feet. Our crawl space moisture control services target the excess humidity that often fuels pest problems from the ground up

Cockroaches and Spiders

Cockroaches have a strong preference for humid areas with access to water. Kitchens, bathrooms, and laundry rooms are common hot spots. Similarly, spiders are drawn to these areas not because they like the humidity, but because their prey does.

Our home pest control plan includes treatments for roaches, spiders, and other common indoor invaders, tailored for seasonal shifts.

Moisture Creates a Domino Effect in Pest Behavior

Humidity doesn’t just attract pests—it creates a ripple effect. As moisture accumulates, it leads to wood rot, fungus, and mold, all of which are attractants or nesting cues for certain bugs. Those pests, in turn, attract their predators.

For example, a damp crawlspace can draw in carpenter ants, which then attract spiders. Mosquitoes may lay eggs near outdoor lighting or downspouts, encouraging more spider webs as well. It’s a cascading ecosystem; without professional control, it can grow quickly.

Homeowner Tips to Reduce Moisture and Bug Activity

While no DIY method replaces professional control, homeowners can help reduce pest pressure by addressing certain moisture risks around their property. Here are a few practical steps:

• Inspect for leaky pipes and fixtures regularly. Even minor drips can keep areas under sinks humid enough for pests to settle in.
• Ensure gutters and downspouts are clear and direct water away from the foundation. Overflowing gutters cause water pooling near entry points.
• Trim shrubs and vegetation away from the house. Overgrown landscaping traps humidity and offers cover for bugs like mosquitoes and roaches.
• Consider venting your crawlspace or upgrading to a closed crawlspace system. Excess humidity under your home can lead to long-term pest and structural problems.

Of course, these steps are most effective when paired with a professional service plan.

Why Moisture Control Is Critical in Hampton Roads

The coastal climate in southeastern Virginia brings naturally high humidity levels and frequent rainfall. That combination makes moisture control a necessity, not just for pest prevention, but also for the health and stability of your home.
