The first step in getting rid of flying ants or termites is figuring out which one you’re dealing with, because the treatment approaches are completely different. Flying ants are a nuisance that you can often handle yourself. Termites, especially in large numbers indoors, signal a colony actively feeding on your home’s wood and typically require professional treatment.
How to Tell Flying Ants From Termites
You can distinguish the two with a close look at a single specimen, alive or dead. Flying ants have a pinched, narrow “wasp waist” between their midsection and abdomen. Termites have a thick, straight body with no visible waist. Ant antennae are bent at an angle, while termite antennae are straight and beadlike. Finally, check the wings: an ant’s front wings are noticeably longer than its hind wings and tinted brown, while a termite’s four wings are all roughly the same length and pale, almost translucent.
Both insects swarm at certain times of year when reproductive members leave the colony to mate and start new colonies. Finding a handful near a window doesn’t always mean trouble. But large numbers of either insect emerging from your walls, floors, or ceiling indicate an established colony living inside the structure.
Getting Rid of Flying Ants
Flying ants are the winged reproductive members of an existing ant colony. Killing the swarmers you see won’t solve the problem. You need to locate and eliminate the colony itself.
Start by sealing entry points around windows, doors, and cracks in walls to keep new swarmers from coming inside. A vacuum cleaner handles the immediate swarm quickly. Then shift your focus to the nest. Bait traps are the most effective DIY option because worker ants carry the bait back to the colony and share it, eventually reaching the queen. Without killing the queen, the colony survives and keeps producing swarmers.
Boric acid mixed with sugar works as a homemade bait. It’s a stomach poison that disrupts ants’ digestive systems, and because it kills gradually over hours to days, workers have time to carry it deep into the colony before dying. Diatomaceous earth is another option for areas where you’ve seen ant trails. It damages their exoskeletons and causes dehydration. Both are considered more natural alternatives, but they work best as part of a broader approach, not as standalone fixes.
If you’re dealing with carpenter ants specifically (the large black or reddish ants that nest in damp wood), check for soft, moisture-damaged wood in your home. Carpenter ants don’t eat wood like termites do, but they tunnel through it to build nests. Repairing or replacing damp or rotting wood removes their preferred nesting sites. If the infestation persists after baiting and sealing, or if you can’t locate the nest, a pest control professional can trace foraging trails back to the colony.
Getting Rid of Termites
Termite control is a different challenge entirely. These insects cause billions of dollars in structural damage annually, and a colony can feed on your home for years before you notice. DIY treatments rarely eliminate entire termite colonies, so professional treatment is the standard approach.
Subterranean Termites
Subterranean termites live in the soil and build mud shelter tubes up foundation walls to reach the wood in your home. The two main professional treatments are liquid soil barriers and bait stations.
Liquid barriers involve injecting termiticide into the soil around your home’s foundation, creating a chemical perimeter that kills termites as they pass through. These treatments typically last 5 to 10 years. They’re effective when the applicator achieves thorough underground coverage, but results can fall short if the soil conditions are difficult or termite pressure is especially high.
Bait stations are installed in the ground around the structure. They contain slow-acting insecticides that prevent termites from molting successfully. Worker termites feed on the bait and carry it back to the colony, gradually killing it from within. A University of California study found that three different bait systems all effectively eliminated termite colonies and prevented structural infestations over a two-year period. The tradeoff is time: bait systems work more slowly than liquid treatments and require ongoing monitoring, typically costing $200 to $400 per year after the initial installation.
Drywood Termites
Drywood termites live entirely inside the wood they eat, with no soil connection. Treatment options fall into two categories: whole-structure and localized.
Fumigation is the most thorough whole-structure option. The building is tented and filled with gas that penetrates all wood, killing termites within several days. Monitored fumigation, where gas levels are tracked inside the structure, has the highest success rate. It’s also the most expensive option, typically running $2,500 to $7,500 or more.
Heat treatment is a nonchemical whole-structure alternative. All wood in the building is heated to a minimum of 120°F and held at that temperature for at least 33 minutes. It avoids chemical residues but requires specialized equipment.
For smaller, localized infestations limited to a single board or small group of boards, spot treatments are available. These include injecting insecticide directly into infested wood, applying heat to a targeted area, using microwave devices that essentially cook termites inside the wood by boiling cell fluids, or even high-voltage electrocution devices that deliver 90,000 volts at very low current. Wood replacement is another option if the infested section is accessible and clearly defined. Spot treatments cost significantly less ($300 to $800) but depend entirely on accurately locating every infestation. Miss one, and the colony survives.
What Professional Treatment Costs
For most homeowners, professional termite treatment runs between $1,000 and $3,500. Liquid barrier treatments fall in the $1,000 to $3,000 range. Bait system installation runs $1,200 to $3,500, plus annual monitoring fees. Fumigation for drywood termites is the priciest at $2,500 to $7,500 or more, depending on the size of the structure. Most professional treatments include warranties, which is one of the main advantages over DIY attempts.
Signs You Need Professional Help
Some situations clearly call for a professional inspection rather than a DIY approach. If you see termite swarmers emerging directly from your walls, ceiling, or floors, a large colony is actively feeding on the building. Piles of shed wings indoors point to the same conclusion.
Mud shelter tubes on your foundation walls are one of the most reliable signs of subterranean termite activity. These pencil-width mud tunnels run vertically up exterior or interior walls, support piers, or plumbing. If you find one, break away a one-inch section and check back over the next few days. If you see live termites or the tube gets repaired, the infestation is active. Mud tubes found higher on the building, on interior walls, ceilings, soffits, or fascia boards, often indicate a more serious infestation.
Small BB-sized spots of dried mud on interior walls or ceilings are another warning sign. Scrape one away to see if there’s a hole underneath, and watch for a termite coming to investigate or for the spot to be patched over the following days. Visible wood damage, hollow-sounding wood when tapped, or sagging floors and ceilings all warrant an immediate professional inspection.
Prevention for Both Pests
Whether you’re dealing with ants or termites, moisture is the common thread. Wood with a moisture content of 15% or higher attracts both carpenter ants and termites. Fix plumbing and roof leaks, improve ventilation in basements, attics, and crawlspaces, and keep gutters clear so water doesn’t pool against your foundation.
Pull mulch and soil back from direct contact with your siding. Even a few inches of clearance breaks the moisture bridge that softens wood and invites pests. Store firewood off the ground and well away from your foundation, and remove dead stumps or rotting wood from your yard.
Trim trees and shrubs so no branches touch your roof, siding, or eaves. Overhanging vegetation acts as a bridge that lets foraging ants reach the structure without crossing open ground. In late winter or early spring, before ant season starts, walk your foundation perimeter and look for existing trails. Mark every entry point and seal it with silicone caulk. Use concrete-rated caulk on foundation cracks, and seal gaps around windowsills, door frames, and utility penetrations.
