Kensington Termite Control

Termites cause over $5 billion in damage across the United States each year, and Maryland sits squarely in the high-risk zone for Eastern subterranean termites. The average undetected infestation costs homeowners between $3,000 and $5,000 in structural repairs before anyone realizes there's a problem. In Kensington's older homes—especially those with stone or brick foundations in the Historic District or aging crawlspaces in Rock Creek Hills—termite activity can stay hidden for years.

Eastern subterranean termites live underground and enter your home through the soil. They build mud tubes—pencil-width tunnels—to reach wood, and they feed from the inside out. By the time you see visible damage or discarded wings near your windows, the colony may have been at work for months. Properties near Rock Creek, Rock Creek Park, and the creek's tributaries face the highest pressure because the permanently moist soil supports larger, more active colonies year-round.

Early detection prevents expensive structural repairs. In Kensington's humid climate, subterranean termites can be active year-round, but they're most visible during spring swarming season—typically March through May. That's when winged reproductive termites emerge to start new colonies. You may find discarded wings near windowsills, light fixtures, or sliding glass doors.

Between swarm seasons, look for mud tubes along your foundation, on basement or crawlspace walls, or running up the masonry. Tap wood trim around doors, windows, and your porch with a screwdriver—a hollow sound means termites may be eating from the inside. Bubbling paint, small piles of soil-like debris, and soft spots in flooring all point to activity. Not sure whether the winged insects you spotted are termites or flying ants? Our guide to termite swarmers walks through the difference. In Kensington's older Victorians and Foursquares with original wraparound porches and wood posts, earth-to-wood contact is common, so it pays to have those areas inspected.

High-Risk Areas in Your Kensington Home

• Basements and crawlspaces near Rock Creek that stay damp after rain
• Stone and brick foundations in Historic District homes
• Wood-to-soil contact from porch posts, front stoops, or landscape timbers
• Original wood framing and joists in early-1900s Victorians and bungalows
• Mulch beds pushed up against the foundation
• HVAC units along exterior walls that create moisture and thermal gradients
• Aging fences, sheds, and detached garages with posts set directly in the ground

Sentricon is one of the most researched termite baiting systems available, and it's our go-to recommendation for ongoing protection in Kensington. The stations are installed in the ground around your home's perimeter—barely visible once in place. Inside each station is a cellulose matrix laced with noviflumuron. When foraging termites find it, they recruit nestmates to feed on it. The active ingredient prevents termites from completing their molting cycle, and the colony collapses from the inside out.

Unlike liquid barriers that degrade over time, Sentricon stations are actively serviced by your technician during annual inspections. They check for new activity, replace bait as needed, and assess conditions around your property. For Kensington homeowners who bundle Sentricon monitoring with regular pest control, termite protection is folded into one plan—one bill, one schedule, and unlimited free callbacks if you spot anything between visits.
