Spring in the DMV means cherry blossoms, warmer weekends — and unfortunately, a

surge in pest activity. As temperatures climb across Prince George's County, Anne

Arundel County, Montgomery County, and the rest of the Maryland and DC region,

insects and rodents that spent the winter hiding are now actively seeking food, water,

and shelter.

At Pest Express DMV, we see it every year. The phones start ringing in late March and

don't stop until fall. But here's the thing: the homeowners who take action early in spring

almost always avoid the worst (and most expensive) infestations.

Here's your complete guide to spring pest prevention in the DMV area. Which Pests Are Most Active in Spring?

Ants & Carpenter Ants

As soon as the ground thaws, ant colonies ramp up foraging. You'll notice trails in your

kitchen, bathroom, and along baseboards. Carpenter ants are especially concerning —

they burrow into damp or damaged wood and can cause serious structural damage to

your home over time.

Termites

Spring is swarming season for termites. You may notice small winged insects near

windows, doors, or light fixtures — these are termite swarmers looking to establish new

colonies. Maryland is classified as a moderate-to-heavy termite risk zone by the U.S.

Department of Housing and Urban Development, which means your home is a target.

Mosquitoes

With spring rain comes standing water — in gutters, flower pots, birdbaths, and low-

lying areas of your yard. That standing water is a mosquito breeding ground. Mosquito

populations in the DMV area have been particularly aggressive in recent years, and

they carry diseases like West Nile virus and Zika.

Ticks

Ticks become active when temperatures consistently reach 45°F and above. If you have

a yard with tall grass, leaf litter, or wooded borders, ticks are already waiting. Lyme

disease remains a significant concern in Maryland.

Rodents

Mice and rats that moved indoors during the cold months are now breeding rapidly. A

single pair of mice can produce up to 60 offspring per year. If you hear scratching in

walls or notice droppings in your attic, basement, or garage, act immediately.

Stink Bugs

These overwintering pests start emerging from wall voids and attics as temperatures

rise. While they're mostly a nuisance (that smell!), large numbers can be overwhelming.

7 Expert Tips to Pest-Proof Your Home This Spring

1. Seal Entry Points

Walk around your home's exterior and look for cracks, gaps, and holes — especially

around the foundation, doors, windows, pipes, and utility lines. Seal them with caulk or

steel wool. Remember: mice can squeeze through a gap the size of a dime.

2. Eliminate Standing Water

Dump out anything holding stagnant water in your yard. Clean gutters so water flows

freely. Fix leaky outdoor faucets. This is the single most effective thing you can do to

reduce mosquito populations around your home.

3. Clean Up Yard Debris

Leaf piles, stacked firewood, and excess mulch near your foundation create perfect

hiding spots for ants, termites, ticks, and rodents. Keep firewood at least 20 feet from

your house and trim bushes that touch your exterior walls.

4. Check Your Crawl Space and Basement Look for signs of moisture, water damage, or pest activity. Termites love damp wood.

Rodents love dark, undisturbed spaces. A quick inspection now can catch problems

before they escalate.

5. Store Food Properly

Inside your home, make sure pantry items are in sealed, airtight containers. Don't leave

pet food out overnight. Keep counters, floors, and dining areas clean — crumbs and

spills are an open invitation for ants and roaches.

6. Maintain Your Lawn

Keep grass trimmed short, especially near your home's perimeter. This reduces tick

habitat and makes your yard less attractive to rodents. Remove any abandoned

planters, old tires, or junk that pests can nest in.

7. Schedule a Professional Spring Inspection

DIY prevention is great, but it's no substitute for a trained eye. A professional inspection

can identify termite damage, hidden entry points, moisture issues, and active pest

colonies that you'd never spot on your own.

When to Call a Professional

If you notice any of the following, don't wait — call a pest control professional:
Winged insects swarming near windows or lights (possible termites)
Mud tubes along your foundation (active termite colony)
Ant trails that keep coming back despite cleaning
Droppings or gnaw marks in your kitchen, attic, or garage
Unexplained wood damage or hollow-sounding wood
Mosquito populations that seem unusually heavy in your yard
