Baltimore County Pest Control

Baltimore County provides a mix of forest, cities, and suburban communities—each of which provides the perfect environment for insects and rodents. Whether you reside in Towson, Catonsville, Parkville, or along the Gunpowder River, insects and rodents can infest your home when you least expect it.

Following is the list of some of the most common pests of Baltimore County:

Ants

Carpenter ants are a major problem in forested neighborhoods, and odorous house ants are usually indoors. They're tenacious and difficult to get rid of without expert help.

Cockroaches

Baltimore County's older buildings and city-border neighborhoods are a roach haven. They are fast, filthy, and resilient—spreading allergens and germs that can affect your health and well-being.

Termites

These wood-boring insects are ubiquitous in the county. Without protection, they silently infest beams, walls, and floors from the inside out before you realize it.

Mosquitoes

The presence of ponds, wetlands, and home ponds ensures mosquitoes are widespread in warm weather. The pesky insects have the potential to ruin outdoor recreation and transmit lethal diseases.

Rodents (Rats & Mice)

Rodents are known to invade homes through crevices or vents, particularly during winter. Rodents cause property loss, gnaw on wires, and cause allergies and disease through feces.

Spiders

Though most are harmless, spiders are often found in basements, attics, and garages. Their webs are a nuisance, and their presence often means there’s another pest issue nearby.

Fleas

Flea infestation is a problem for both pet owners and residents of apartments in Baltimore County. The little jumpers breed quickly and are hard to get rid of without adopting a county-wide plan.

Ticks

Even lawns in suburban areas can contain ticks, especially where trees and tall grass meet. Ticks are known to transmit Lyme disease and are active throughout the year in this region.

Stink Bugs

They are the ones that come into your house in autumn so that they can avoid the cold. Although they don't bite or sting, they are hard to manage and also leave very pungent odor.

With suburban neighborhoods, dense urban areas, and wooded parks, Baltimore County sees a wide variety of seasonal pest problems. Here's what to watch for throughout the year.

Spring: Swarm and Rebuild

The warmer climate and blooming surroundings trigger intense pest activity—most notably wood destroyers and stingers.

Common Spring Pests:

• Termites: Begin swarming in April and may be seen near windows or baseboards.
• Ants (Carpenter & Odorous): Appear indoors searching for food and moisture.
• Stink Bugs: Move from inside the home to the outdoors.
• Bees & Wasps: Begin nest building in attics, gutters, and undersiding.

Prevention Tips:

• Clear away old wood, leaves, and brush near the house.
• Reseal any gaps around utility lines and foundation.
• Get a professional termite barrier in place early.

Summer: Buzzing, Biting, and Nesting

Summer in Baltimore County means cookouts—and bugs. Heat encourages population booms in many species of bugs.

Common Summer Pests:

• Mosquitoes: Especially bad near streams, storm drains, and standing water.
• Ticks: Found in wooded parks like Patapsco and backyard brush.
• Fleas: Multiply rapidly on pets and indoor furniture.
• Hornets & Yellowjackets: Aggressive and protective of growing nests.
• Flies: Attracted to trash, pet waste, and compost.

Prevention Tips:

• Clean gutters and remove water-holding containers.
• Wear long sleeves when walking in wooded areas.
• Secure trash bins and keep lids tightly closed.

Fall: The Great Pest Migration Indoors

As the temperatures drop, Baltimore County pests seek warmth indoors.

Common Fall Pests:

• Rodents (Mice & Rats): Look for easy access points into garages, kitchens, and basements.
• Spiders: Come indoors following prey.
• Stink Bugs & Boxelder Bugs: Crawl into siding and attic spaces.
• Crickets & Centipedes: Invade basements and bathrooms.

Prevention Tips:

• Seal all gaps under doors, around pipes, and against the foundation.
• Gathered wood must be relocated at least 20 feet from a dwelling.
• Store seasonal decorations in an airtight container.

Winter: Hidden Infestations

While restrained on the outside, pest activity remains unchecked indoors in Baltimore County.

Common Winter Pests:

• Mice & Rats: Nest in walls, behind appliances, and attic insulation.
• Cockroaches: Thrive in warm kitchens and behind water heaters.
