Termite Treatment in Dallas, TX

What to look for

Two species do almost all the structural damage in Texas, and Texas A&M names both: the eastern subterranean termite and the Formosan subterranean termite. Neither one flies into your attic and starts chewing. They live in soil colonies, and they reach the house through wood that touches dirt or through shelter tubes built over and through cracks in the foundation. That matters in Dallas because of how the ground behaves here. Thirty nine inches of rain a year, most of it in spring bursts, keeps the clay soil around a slab swelling and shrinking. Every cycle opens hairline gaps at expansion joints, plumbing penetrations, and mortar. Those gaps are the doors. Humidity averaging 65 percent and summer highs near 96 degrees mean the colony never really pauses. Workers forage year round under mulch, under patio slabs, and inside the moist soil shadow along the north side of a house. By the time you see damage, the colony has usually been in the wall for a couple of seasons.

• 1Pencil width mud tubes climbing the outside of a slab or pier, often hidden behind shrubs.
• 2A scatter of equal length wings near a sunny window in late winter or early spring.
• 3Wood trim that sounds hollow when you tap it with a screwdriver handle.
• 4Paint that bubbles or ripples on a baseboard with no plumbing leak behind it.
• 5Sticking doors and window frames that got tighter over one season rather than gradually.
• 6Soil packed into a crack in a garage slab or into a mortar joint on a brick veneer.
• 7Damaged wood that splits along the grain and holds dried mud inside the galleries.

Which termites will you actually meet in Dallas?

Texas A&M identifies the eastern subterranean termite and the Formosan subterranean termite as the two economically important species in Texas, and both matter around Dallas. The eastern subterranean is the one you are most likely to see. Its swarmers fly in daylight, usually on a mild afternoon after a spring rain, and they leave behind a drift of shed wings on a sill or in a spider web. Formosan colonies are larger and more aggressive, and their swarmers fly after dark, which is why people find them around porch lights and pool lights rather than on windowsills. Southern extension programs put Formosan flights from roughly late April through July in the evening hours. The practical difference for a homeowner is speed. A Formosan colony can build satellite nests above ground where moisture allows it, so a leaking shower pan or a chronically wet wall can host activity that is not tied to the soil line. Tell the inspector what time of day you saw the swarm. That single detail steers the identification more than a photo of the wings does.

A termite calendar for North Texas.

January and February belong to South Texas, where Texas A&M says swarming begins. Around Dallas the ground is usually still too cool, but a warm stretch can pull an early flight out, so a January swarm here is not impossible and is worth photographing. February through April is the main event. Eastern subterranean swarmers come out during the day, often within a day or two of rain, and this is when most people first learn they have a problem. It is also the busiest stretch for inspection calendars, so booking takes longer. May and June bring the evening Formosan flights. If you see winged insects circling an outdoor light after sunset, note the date. From July through September the swarms taper off, but foraging does not: with summer highs near 96 degrees, workers simply move deeper into moist soil under slabs and patios. October through December is the quiet stretch and the best time to buy treatment. Crews have room in the schedule, the ground is workable, and a barrier installed in fall is in place before the spring flights start.

What drives the price on a Dallas home.

Almost every liquid treatment quote in Dallas is built on linear feet of foundation. A long, single story ranch can cost more to treat than a taller house with a compact footprint, even though the ranch has less square footage inside. Measure the perimeter yourself before the estimator arrives and you will know immediately whether a number is in the right neighborhood. Concrete is the second driver. Attached garages, wraparound patios, and driveway slabs poured against the house all have to be drilled and patched, and each drilled foot adds labor. Houses with a pier and beam crawlspace trade drilling for access problems, and a tight crawl adds time. Bait systems price differently. You are paying for stations, placement, and a recurring service schedule, so the yard drives the number more than the house does. Deep lots and heavy landscaping mean more stations. With a median Dallas home value around $314,000, treatment is a small fraction of the asset it protects, but that is no reason to skip line item comparison between two bids.

How to compare two termite quotes without getting lost.

Find out which bid includes any repair work and which quietly leaves it to you, because that gap can be larger than the difference between the two prices. Termite companies treat insects; carpenters replace wood. Fourth, the repairs. Get the answer by email rather than as a verbal reassurance. Ask what the renewal costs in year two and what happens if activity returns inside the coverage period. Third, the term. For baits, ask how many stations and how often somebody comes back. Short volume is the most common way a cheap barrier turns into a failed one. For a liquid job, ask how many linear feet are being treated and how many gallons the label calls for at that footage. Second, the scope. A quote with no diagram is a price for a product, not a plan for your house. First, the diagram: a serious inspection produces a sketch showing where tubes, damage, and moisture were found. Put the two bids side by side and look for four things.

Renters, landlords, and who pays in a Dallas rental.

Structural pests are generally the owner's problem, and termites are about as structural as it gets. If you rent in Dallas and find mud tubes or a swarm indoors, put it by email or text to the landlord or property manager the same day, with photos and the date. A text message is fine; the point is a timestamp. Landlords have a scheduling reason to move quickly. Treatment is disruptive: crews drill through garage and patio concrete, work along every exterior wall, and need clear access to the perimeter. That is far easier between tenancies than during one, and it is far cheaper during the fall lull than during the spring swarm rush. For a small multifamily building, a bait system can be the easier fit, because stations go in once and a technician services them without needing interior access on a set day. Whichever route an owner takes, tenants should ask for the treatment plan on paper, including which areas require access and how long the crew expects to be on site.

Simple ways to keep termites away

• Keep mulch, soil, and flower beds several inches below the top of the slab.
• Store firewood off the ground and away from the house, especially through winter.
• Repair drip irrigation heads that soak foundation soil during long Dallas summers.
• Clear gutters so the 39 inches of annual rain leaves through downspouts, not down the wall.
• Replace wood fence posts and deck stringers that sit directly in dirt against the house.
• Check the garage slab crack and the water heater platform once a year with a flashlight.
• Ventilate a pier and beam crawlspace so the soil under the house dries between rains.
• Have the house inspected annually once a barrier passes its fifth year.
