Termite control in Round Rock, TX.

Two kinds of ground meet in Round Rock: Edwards limestone west of I-35 and blackland clay to the east. Subterranean termites will work either one. Our answer is in-ground bait stations that the colony ends up feeding on itself, plus official WDI reports when you sell. Stations are quoted on inspection, and the WDI report is quoted when you book.

Termite control in Round Rock, the short version

I-35 splits Round Rock into limestone to the west and blackland clay to the east. Termites work the soil on both sides, so what matters is where the damp ground meets your slab.

In Round Rock, termite work is quoted on inspection.

A Forest Creek ranch on a slab from the late 80s and a Teravista two-story on new concrete are not the same job, so we see the house before we name a price. Foundation type, the length of wall and where termites are working set the number, and you have it in hand before we start. Termite work sits outside the monthly general pest plan, and a WDI report for a sale is quoted when you book.

Our approach

How we treat termites in Round Rock.

No sprayer in this one. Subterranean termites feed inside wood and soil you cannot see, so the work comes in three steps: find them, put bait where they forage, and keep checking until the feeding stops.

Inspect

Before a single station goes in, we find the activity. Flashlight, probe and moisture meter along the garage slab joint, the slab edge and each plumbing opening. On the older Forest Creek and Stone Oak slabs near Brushy Creek, the settled cracks get extra attention.

Install stations

Stations are set into the soil around the house, mostly in the mulch beds along the foundation, where the workers already forage. Workers feed on the bait and take it back to the colony. The active ingredient works slowly by design, so everyone gets a share. Free labor, courtesy of the termites.

Monitor

Every station gets checked on a schedule, and we add bait wherever termites are feeding. Complete control can take several weeks, per Texas A&M. We leave the stations in after the colony is gone, since a new one can move into the yard later, on either side of I-35.

What brings termites to Round Rock houses.

Termite control in Round Rock changes with the ground. West of I-35, the soil is thin over limestone, so the damp pockets termites need sit right at the slab edge, the garage joint and the sprinkler valve boxes. East through Teravista, Paloma Lake and Chandler Creek, blackland clay holds rainwater, and wet soil against a foundation is exactly what a subterranean colony is looking for. Heavily irrigated lawns on both sides keep the strip along the house damp. From that soil the workers run pencil-width mud tubes up over the concrete, and most owners never see more of the colony than that.

Round Rock sits right on the geological seam, and I-35 roughly marks it: Edwards limestone on the west side through Behrens Ranch, Mayfield Ranch, Vista Oaks and Cat Hollow, heavier blackland clay to the east through Teravista, Paloma Lake and Chandler Creek. Brushy Creek crosses town west to east and carries damp ground through the middle of it, past the older streets of Forest Creek and Stone Oak, where mature canopy shades slabs poured in the late 80s. Damp soil with wood in reach is the whole termite recipe.

Here's the thing about the wings on the windowsill. The insects that left them are swarmers. They cannot damage wood, and they only live about a day. Swatting them is housekeeping, not termite control, and the colony will never know. The ones eating your trim are workers, and workers stay sealed inside the soil, the wood and their mud tubes, out of reach of anything you could spray. So we go the other way. A bait station puts food where workers already forage. They eat it, haul it home and share it with the rest of the colony, and because the active ingredient acts slowly, it travels through the colony before it kills. Texas A&M counts that in weeks, so we keep checking stations on a schedule rather than calling it done after the first visit. Clay east of I-35 or limestone west of it, the stations go wherever the workers are already digging.

Limestone west, clay east

I-35 roughly marks the line. Thin soil on one side, wet clay on the other.

Seasonal pattern

When termites swarm in Round Rock.

Spring is when termites show themselves. Texas A&M puts swarms mostly between February and May, with March and April the usual months. Underneath, the colony never takes a month off, so a slow swarm season says nothing about your baseboards.

Typical termite swarm activity in Central Texas by month Native subterranean termite swarms start in February, peak in March and April and taper off through May. A smaller rise in late May and June comes from Formosan subterranean termites, which swarm at night. Swarms are rare the rest of the year, but the colony in the soil keeps feeding in every month. January: low swarm activity February: swarms starting March: very high swarm activity, peak month April: very high swarm activity, peak month May: high swarm activity June: moderate, Formosan swarms at night July: low swarm activity August: low swarm activity September: low swarm activity October: low swarm activity November: low swarm activity December: low swarm activity PEAK SWARMS the colony still feeds all year JanFebMarAprMayJunJulAugSepOctNovDec lowhigh

Relative pattern for swarms, not a measured local count. Texas A&M says termite swarms can happen in any month but are most common from February to May in Texas, with native subterranean swarmers usually seen in March and April, by day.

Native swarms
March and April

Native subterranean termites swarm in daylight, often after a spring rain. Equal-size wings on a Round Rock sill in these weeks mean it is time to call.

Formosan swarms
Late May and June

After dark, drawn to porch lights and windows. Texas A&M records them mostly on the upper Gulf Coast, so one this far inland would be unusual. Send us a photo anyway.

The rest of the year
Every month

Clay side or limestone side, the colony keeps eating through every month. Swarms are just the part that shows.

From real jobs

Every photo below came off a real Round Rock service call. Mud tubes, discarded wings and hollowed wood are the three things that tell you it is termites and not ants.

Tubes up the slab Foundation edge, mulch bed

Three tubes of soil climb out of the mulch and over the slab onto the brick. The broken one shows the inside is hollow, a covered road for workers between the ground and the wood.

Shed wings indoors Inside windowsill

Every wing in the pile is the same size, which is the termite tell. Swarmers shed them right after landing, so a pile on an inside sill means they emerged indoors.

The grain has been eaten out into galleries and packed with dried mud, and the pale workers are still at it. Carpenter ant galleries would be clean and smooth.

Know your pest

The termites we find in Round Rock.

Every termite in a Round Rock yard lives in the soil and comes up to the wood. These are the four you are most likely to meet, and the swarmer is the one most people actually see. Workers do the damage, soldiers guard the tunnels, and swarmers start new colonies.

Reticulitermes spp.

Workers do all the eating. They are wingless, creamy white and 1/4 to 3/8 inch long, and they live sealed inside soil, wood and mud tubes, so you usually see one only when a board gets broken open. Whether the slab sits on limestone west of I-35 or clay east of it, they reach the wood through tubes at the foundation edge, and they are the caste that carries bait home to the colony.

Reticulitermes spp.

Soldiers defend the colony with long, rectangular brownish heads and strong jaws. Find one in broken wood or a damaged mud tube and you have confirmed subterranean termites. That rectangular head also marks a native colony, which is what nearly every termite job around Austin and Round Rock turns out to be, rather than a Formosan one.

Reticulitermes spp.

This is the caste people actually spot. Swarmers run from coal black to pale yellow-brown, about 1/4 to 3/8 inch long, with four pale or smoky wings all the same size. Texas swarms come by day, mostly February to May and usually March and April, so a Round Rock spring is when they show up. One indoors means a colony is feeding in that wall.

Coptotermes formosanus

Watch the head. A Formosan soldier's is shaped like a teardrop or an egg, not the native rectangle, and it releases a white defensive drop when disturbed. Texas A&M records this termite mostly on the upper Gulf Coast, so finding one in Round Rock would be unusual. Its yellowish-brown swarmers fly toward lights at night in late May and early June.

Warning signs

Signs termites are already in the house.

Most termite jobs start with something left behind, not a live termite. West of I-35 the thin soil over limestone puts the evidence right at the slab, and east of it the wet clay keeps the tubes coming, so tell us your side of the highway when you call. Bag a few swarmers or freeze them, remember where they came out, and send a sharp photo. That often answers termite or flying ant before a truck rolls.

  • Thin brown mud tubes running up the slab from the soil
  • Little piles of same-size wings on a sill in spring
  • Winged termites emerging inside on a March or April day
  • Baseboards or trim that sound hollow, blister or give under a screwdriver
  • Dried soil packed into cracks or along the baseboard
  • Tubes around plumbing openings or the garage slab joint
  • Mud tubes rising from a thin bed over limestone on a west-side lot
  • Mud tubes on the slab where clay stays wet in Teravista or Paloma Lake

Where we do termite work in Round Rock.

West of I-35 in Behrens Ranch, Mayfield Ranch and Cat Hollow, the soil over the limestone is thin, so the damp ground termites need sits right at the slab. East in Teravista, Paloma Lake and Chandler Creek, the clay holds water against the foundation. Forest Creek and Stone Oak add older slabs under mature canopy along Brushy Creek. Tell us your street and we will tell you which of those three we expect to find.

Round Rock termite questions.

What does termite treatment cost in Round Rock?

There is no set price, because a Stone Oak slab from the late 80s and a new Teravista build are different jobs. We inspect first, then quote on slab or pier and beam, the length of the foundation and where termites are active. That inspection is free and carries no obligation. Termite work is not included in the monthly general pest plan, and a WDI report for a sale is quoted when you book.

How do I tell a termite swarmer from a flying ant?

Look at the waist, the antennae and the wings. Termites are thick through the middle, with straight, beadlike antennae and four wings all the same size. Flying ants have a pinched waist, elbowed antennae and a front pair of wings longer than the back. Put one on a white paper towel and zoom in with your phone, or use our termite vs ant swarmer guide. Ants? Then you want ant control in Round Rock.

I found swarmers inside my Round Rock house. Do I have termites?

Almost certainly, if they came out indoors. Swarmers leave from a colony already feeding in that wall, though the swarmers themselves cannot damage wood and only live about a day. Swarmers in the fence or the woodpile are a different story, since that colony may never have reached the house. Walk the slab edge for mud tubes either way.

What months do termites swarm in Round Rock?

Round Rock runs on the same calendar as the rest of the state. Per Texas A&M, swarms are most common February to May, usually March and April, and native subterranean termites fly by day. Formosan termites fly at night in late May and early June, toward lights. Either way, the colony in the soil keeps feeding every month.

Can you do a liquid termite treatment instead of bait?

No. In-ground bait stations are the only termite treatment we offer, alongside WDI reports for home sales. The colony does the distributing: workers eat the bait in the soil and feed it to the rest. We check stations on a schedule and top up bait where termites are feeding, and they stay in the ground afterward in case a new colony moves into the yard.

Should I get a termite inspection before selling in Round Rock?

Often, yes. A WDI (wood destroying insect) inspection is a look at the visible areas for termites, other wood destroying insects and the conditions that invite them, and in Texas it goes on the form the Texas Department of Agriculture prescribes. VA loans require one anywhere in the state, and other lenders and buyers may ask for one too. The report is quoted when you book, and we are licensed in Texas.

Does it matter which side of I-35 my Round Rock house is on?

It changes where we look, not what we use. West of I-35 in Vista Oaks or Cat Hollow, the soil over the limestone is thin, so the damp strip termites need is right against the slab, under the beds and around the valve boxes. East in Teravista or Paloma Lake, blackland clay holds rainwater against the foundation. Either side, it is bait stations in the soil where workers forage, quoted on inspection.

Can termites come up through an older Round Rock slab?

They use whatever gap the slab gives them. A slab poured in the late 80s in Forest Creek or Stone Oak has had decades to settle, and hairline cracks and plumbing penetrations are routes from the soil to the wood. Look for mud tubes at plumbing openings and dried mud packed in cracks or along baseboards. We inspect those first, set stations in the soil outside, and point out any gap worth fixing.
