Ant Control Built for Annandale's Older Homes
58 Years Protecting Fairfax County Families
Annandale has everything ants love. Wooded stream valleys along Accotink Creek. Mature trees in every neighborhood. And thousands of homes with 60-year-old foundations full of cracks and gaps. From the streets of Broyhill Crest and Canterbury Woods to the shady lots of Sleepy Hollow and Camelot, ants have plenty of places to nest — and plenty of ways into your home.
Better Termite & Pest Control has been getting rid of ants in Annandale since 1968. We use products ants can't detect. They walk through the treated area, carry it back to their colony, and spread it to their nestmates. The whole colony dies — not just the ones on your counter. Our research team cut 9 of the harshest chemicals from our lineup and picked products like Essentria and Alpine that we use in our own homes.
Plans start at $39/month with triannual visits and unlimited free callbacks. No binding contracts — you can cancel anytime with 30 days notice. Call 703-683-2000 and talk directly to a licensed technician for a phone quote. No phone trees, no runaround.

Why Annandale Has a Serious Ant Problem
Accotink Creek, Stream Valleys, and Red Clay
Accotink Creek cuts right through Annandale, and the area has close to two dozen parks — Hidden Oaks Nature Center, Mason District Park, Backlick Stream Valley, Indian Run, Turkeycock Run. Many of these wooded areas run right behind homes in Broyhill Crest, Camelot, Columbia Pines, and Canterbury Woods. Ants nest in the leaf litter, rotting logs, and damp soil along the creek banks. When they need food and water, they head straight for your house.
Annandale's red clay soil drains poorly and holds water in low spots. That creates the damp ground carpenter ants and kitchen ants need to thrive. Add in summer humidity above 65% and 3-4 inches of rain per month from April through October, and ant pressure stays high from early spring into late fall.
1960s Construction Means More Entry Points
The typical Annandale home was built around 1967. Most are ranchers, split-levels, and Colonials with brick over wood framing. After 50-60 years, foundations shift. Gaps open at joints. Cracks widen around pipes and wiring. Sill plates rot. All of this gives ants easy access to wall voids and basements.
Carpenter ants do the most damage. They don't eat wood — they carve it out to build nests, going after spots with moisture damage. Odorous house ants are the small black ants that trail across kitchen counters. Pavement ants nest under driveways and walkways. And acrobat ants get in through damaged wood or old foam insulation.
Carpenter Ant Removal in Annandale
The Biggest Ant Threat to Your Home's Structure
After termites, carpenter ants are the biggest wood-destroying pest in Annandale. These large black ants hollow out wood to build their nests. They go after spots where moisture has already softened the wood. In Annandale's older homes, that usually means sill plates, deck posts, porch beams, and window frames — especially in homes near Accotink Creek or Green Spring Gardens.
Here's what to watch for: small piles of sawdust near wood surfaces, faint rustling sounds in walls at night, and large black ants (sometimes with wings in spring). One colony can hold 3,000+ ants, and they often set up backup colonies in other parts of the same home.
How We Eliminate Carpenter Ant Colonies
We start by tracing the colony back to its source. Carpenter ants follow moisture, so we check gutter overflows, damp crawlspaces, leaky pipes, and wood touching the ground. Then we apply a non-repellent product to cracks, gaps, and wall voids. The ants can't detect it. They carry it back to their nestmates, and the whole colony dies off within 2-4 weeks.
Kitchen Ant Problems in Annandale
Why Those Small Black Ants Keep Coming Back
Those tiny ants marching across your kitchen counter? They're most likely odorous house ants. Crush one and it smells like rotten coconut — that's how they got the name. In Annandale, they're everywhere. They nest outside in mulch beds, under stones, and in thick leaf litter under trees. When they need food or water, they follow scent trails through tiny cracks in your foundation and gaps around pipes.
They're worst in shady Annandale neighborhoods like Camelot, Sleepy Hollow, and the streets near Mason District Park. The shade and damp ground are perfect for their nests. And the older pipes in 1960s homes give them a direct path inside.
Why DIY Ant Sprays Make It Worse
These ants have multiple queens per colony. When they sense a repellent spray, they don't die — they split up and scatter into new colonies. That's called "budding," and it's why store-bought ant sprays often make things worse. Our products are non-repellent, so the ants never know they've been treated. They carry the material back to the colony and wipe it out. With a perimeter barrier and 3 visits per year, we break the cycle for good.

What to Expect During Your First Visit
Interior: Find the Trails, Treat the Source
Our technician starts inside your home. We focus on the rooms where you've seen ants or where they're most likely to show up. In Annandale's older homes, that means kitchens, bathrooms, basements, and the gaps around old pipes and wiring. We trace ant trails back to their entry points and treat cracks, gaps, and wall voids where ants travel.
This targeted approach means no broad-spray treatments across your living spaces. You won't need to leave your home or clear out cabinets. We treat the pathways ants are actually using, not every surface in the house.
Exterior: Build a Barrier That Lasts
Outside, we check the full perimeter — foundation walls, window frames, door sweeps, garage entries, and where mulch or plants touch the house. We lay down a barrier that stops new ants from getting in. We'll also point out things you can fix, like mulch piled against siding, branches touching the roof, or gutters pushing water toward your foundation.
What Annandale Area Homeowners Say
1,100+ 5 Star Reviews on Google "We've had a subscription service with this company for yrs, since moving into our current house, and realizing it was rather...spidery. But NO MORE! Better Termite uses pet-friendly, but not spider-friendly products, and we are now creepy crawly-free! Over the years, they've also tackled ants, bees, and HORRIBLE paper wasps!"
"Better Termite has been keeping our house bug free for years with regular perimeter treatments. As a small, family owned business, they are able to personalize their approach based on your needs. It's clear that they prioritize customer service and communication. We recently had a swarm of a stinging insect take shelter under our ground-level deck, and they researched, bought necessary equipment, and came up with the best way to treat it."
"I highly recommend this company for your home pest control. Their technicians are thorough and have prevented any unwanted problems from happening on our property. During our last treatment, Jasmine took care of our outdoor spider webs without us even asking. Last summer they removed a mud dauber's nest under our deck and above our patio door. That attention to detail speaks volumes."
"I signed up for a plan and have been truly happy with it. This company is highly professional and very responsive. When I saw fence damage from a carpenter bee, they came out quickly to address the issue right away! Accolades to Cindy the dispatcher, and all the technicians from Juan to Daren to Fredie. I appreciate your service!"
"Daren did an outstanding job conducting my termite inspection today. He was right on time and extremely professional thorough throughout the entire process. I did not have any problems, and he was very good with some solid advice about how to continue to guard against not only termites but other rodents as well. Cindy also expertly took care of me throughout the process."
