Swarms after warm rain, February through May, earliest near Old Town and San Gabriel Park, later as spring cools
Eastern subterranean termites are the native termite found in Georgetown, living in the soil and reaching a house through mud tubes at the slab edge or porch posts. Signs include pencil-width mud tubes, discarded wings on windowsills after a warm rain, and hollow-sounding trim. Treatment targets the soil and slab perimeter, not just the wood.

Mud tubes on a pier or slab edge mean an active route between the soil and the wood above it, and they should not be broken open and ignored. Breaking a tube without treatment just gives the colony a reason to build a new one somewhere less visible. The right move is a licensed inspection to confirm whether the tube is currently in use.
Discarded wings on a windowsill or patio after a rainy spring afternoon mean a colony nearby has reached the age to swarm, which typically happens sometime between February and May in Georgetown. It doesn't confirm that the swarm came from under this particular house, but it's a reasonable trigger to have the slab and foundation checked before summer.
Hollow-sounding or blistered trim near a slab edge means wood has already been fed on, possibly for a while, since damage builds slowly and quietly behind paint or veneer. This is a sign to have both the damage and the surrounding foundation checked, since the wood alone won't show how far the colony has spread.
A widening gap between the clay soil and the slab edge after a dry summer isn't termite damage itself, but it's a conducive condition — an open route to the foundation that termites, ants, and scorpions all use. Worth mentioning to a licensed pro doing an inspection, especially after a summer like 2023's drought across Williamson County.
Georgetown sits on slab-on-grade construction over expansive clay, and that clay is exactly the kind of ground a subterranean colony can work through without ever coming up for air. The termites live in the soil, not in the wood, and they only need a way up through or around the slab to reach the framing above.
Neighborhoods built over the last couple decades, from Teravista out to Wolf Ranch and Cimarron Hills, sit on the same clay as the older streets around Old Town, and a slab is a slab regardless of the build date. Any wood-to-soil contact at a porch step, a deck post, or a stack of firewood against the house gives the colony a shortcut in that skips the slab edge entirely.
Late summer brings the fall field cricket flood, and Georgetown's lit storefronts along Austin Avenue and the pump islands near I-35 draw them by the thousands once the weather turns. A porch light left burning past dark pulls in more crickets than a whole can of spray keeps out. Swapping a white bulb for a warmer one, or just shutting outdoor lights off earlier, thins the swarm more than most homeowners expect.
Flying ants after rain. Winged termites and winged ants get mixed up on a windowsill after a swarm. A termite has four wings of equal length and a thick waist with no pinch; an ant's wings are unequal and its waist narrows sharply. Termite antennae run straight, an ant's bend at an angle. If the wings left behind are all one size, treat it as a termite entry point until a licensed pro confirms it.
Control starts with an inspection that traces where the mud tubes actually run, not just where they are easiest to see, since the visible tube on a pier or slab edge is rarely the only entry point into the structure. The licensed pros we connect you with map the foundation, the porch attachments, and any exterior wood-to-soil contact before deciding where to treat.
From there the usual approach is a liquid termiticide applied around and under the slab perimeter, or a bait system placed in the soil where activity is confirmed, sometimes both on the same house. Either way it is a job for a technician licensed in the termite category, since the goal is to cut the colony off from the structure, not just to spray where the wings turned up.
A scorpion under the bathroom door in July gets a same-day call. A rat scratching in the attic over Wolf Ranch or Teravista in January gets put off for a week, then two. Both are worth acting on quickly, just for different reasons — one is a safety question for anyone with kids or pets in the house, the other is a structural one that gets more expensive the longer a roof line stays open.

A homeowner can knock down a mud tube or clear firewood and mulch off the foundation, and both are worth doing. Neither one kills a colony living in the soil under the slab, and store-bought sprays on a mud tube just push the workers to rebuild a few inches over. Once tubes, hollow trim, or swarmers indoors are confirmed, this stops being a project for around-the-house products.
Eastern subterranean termites do not bite people, sting, or spread disease, and they are not a health hazard to anyone living in the house. The cost is to the structure, not to the occupants, and it runs quietly for a long time before anyone notices, which is why the early signs matter more than the damage itself.
A scorpion under the door or a fire ant mound that showed up overnight after rain is not something to sit on in Georgetown. The licensed pros we connect you with know that the west side of I-35, from Sun City down through Cimarron Hills and Water Oak, is limestone ground where these things move differently than they do east of the highway. Call and describe what you're seeing — a phone call costs nothing and gets you talking to someone who can actually place the problem.Scorpion visits usually come with an entry point already at fault — a slab crack, a loose weep screen, a gap around a laundry line. Fixing that spot is often folded into the same visit rather than billed as extra, since it's a few minutes of caulk and screen versus a repeat call in July. Roof rat exclusion works the same way: the estimate covers sealing the fascia gap or gable vent that let them into the attic in the first place, not just clearing what's already up there. pricing guide, and the service that handles this is Termite Inspection.
Pest Identification. Red imported fire ants build loose dirt mounds with no visible entry hole, sting in a group when disturbed, and can appear across a Georgetown lawn within a day or two of rain.
Pest Identification. Striped bark scorpions are common in Georgetown from April through October, peaking June through August.
Identification & Treatment. House mice get into Georgetown homes through gaps as small as a pencil width along the slab foundation, garage door corners and utility penetrations.
In Georgetown they swarm in daylight after a rain, most often between February and May, though the exact week shifts year to year with the weather. A yard full of discarded wings on a windowsill or a patio slab after a warm, wet spring afternoon is the usual first sign. Swarming doesn't mean an active infestation in that spot, but it does mean a colony is nearby and worth having a licensed local pro check the slab edges and piers before summer.
No. Formosan subterranean termites are established one county south, in Travis County, but they aren't confirmed in Williamson County. What shows up on a slab in Georgetown is the eastern subterranean termite, a slower-building, native species. The two look similar to an untrained eye, so if there's real concern about which one is present, that's a call for a licensed inspection rather than a guess based on what's swarming in Austin.
Treatment doesn't stop after one visit and be done with it, especially after a dry summer. The clay under a Georgetown slab pulls away from the foundation edge in a drought, leaving a gap that the colony can follow back in once the rain returns. That's why a termite program here is usually framed as ongoing monitoring and re-treatment rather than a single application, particularly for houses on Blackland Prairie clay rather than caliche or limestone.
Mud tubes on a pier, foundation crack, or slab edge are the most reliable sign, along with wings shed near a windowsill after a spring swarm and wood trim that sounds hollow or papery when tapped. None of those confirm how far the colony has gotten under the slab. A licensed local inspection is the only way to know whether it's a new tube or years of established activity, and whether nearby wood is structurally sound or just cosmetically intact.
West toward Sun City and Cimarron Hills, the limestone under Water Oak and the DB Wood Road corridor is full of cracks scorpions and ants use to move underground unseen.
