Ant Control in Washington, District of Columbia

Pest problems in Washington are shaped by the place.

  • Small piles of frass near the wood — sawdust-like material from carpenter ants or wood-nesting ants.
  • Mounds in the yard — the raised soil of a fire ant or field ant colony.
  • Ants in the kitchen and the bathroom — foraging workers in the rooms with food and moisture.
  • Winged ants indoors in the spring — swarmers that indicate an established colony.

Why Washington homes get ants

The the coastal plain and the Potomac river valley adds harborage, and the humid subtropical climate keeps the activity going through most of the year. Homes on slab foundations, with crawl spaces, or near the the Potomac and Anacostia rivers and the Chesapeake Bay see the heaviest pressure. The older neighborhoods and the newer subdivisions each bring their own pest profile.

Frequently Asked Questions

Q: Why do ants keep coming back?

Ants follow scent trails, and the colony keeps sending workers until the trail and the food source are gone. The bait removes the colony, not just the ants you see.

Q: Are the baits safe for pets?

The bait is placed in the areas the ants travel and out of reach of pets, per the label. We point out the placements during the service.

Q: How long does the bait take to work?

The bait works over one to two weeks as the workers carry it back to the colony and it spreads. The visible trails thin out as the colony declines.

Q: Do you treat fire ants in the yard too?

Yes. Fire ant mounds are treated directly in the yard, and the treatment is timed to the mound activity in District of Columbia.

Q: How much does ant control cost in Washington?

Baiting runs $120 to $280 in Washington, with a perimeter barrier from $100 to $220. Carpenter ant work runs higher because it involves finding and treating the nest.
