Pest control in Round Rock.
Round Rock has an old-house problem and a new-house problem. Along Brushy Creek, the canopy over Forest Creek and Stone Oak walks roof rats to the roofline. Out in Teravista and Behrens Ranch, fresh slabs on cleared limestone collect displaced scorpions, and the sod arrives with fire ants included.

Why pests behave differently here.
The established neighborhoods along Brushy Creek: Forest Creek, Stone Oak, the older streets near Old Settlers Park, have mature canopy and decades-old slab penetrations. That means roof rats moving along branches into attics, and ants finding their way through settled foundation cracks.
The newer build-out north and east: Teravista, Behrens Ranch, Mayfield Ranch, Paloma Lake, has the opposite problem. Fresh construction on cleared limestone pushes displaced scorpions and fire ants toward the nearest foundation, and new sod often arrives with fire ant colonies already in it.

A relative pattern, not a count, built from Texas A&M AgriLife Extension seasonal guidance and our own service calls around Round Rock. The $66/mo general pest plan covers ants, roaches, scorpions, spiders, wasps and rodents; mosquitoes, fleas, ticks and moles are add-ons. Honey bee swarms are never exterminated: we refer them to a local beekeeper. Carpenter bees we treat directly.

Every Round Rock visit
The full TriBarrier™, every time.
Three overlapping layers, from the foundation out to the property line. Not a hurried spray along the baseboards. Two of the three are the layers your cheaper quote is quietly leaving out.
Foundation barrier
Three feet up the wall and three feet out from it, the whole way around the house, plus windows, doors, garage and roofline. That band is the route pests actually take to get inside.
Measured with a tape, not eyeballed
Granular yard moat
A ring of granular treatment across the lawn that wakes back up every time you water or it rains. Your sprinklers are on our payroll now.
Skipped by most companies. Granular costs money.
Property line
A full 360-degree spray along the property line, so pests get turned back at the border instead of at your back door.
Skipped by most companies. Nobody audits a lawn.
Everybody in this business says three feet up and three feet out. We are the ones who actually bring a tape measure, and every Round Rock visit gets all three layers. There is no cheaper Bastion tier where we quietly drop a layer, because free re-treatments only work if the treatment was real the first time. That is the difference you are paying for.
They come back? So do we, free.
Free re-treatments between scheduled visits on any recurring plan. We keep our routes tight around Round Rock, so when you call we can actually get back out.

Round Rock pest questions, answered.
What month are pests worst in Round Rock?
Two spikes. April and May bring fire ant mounds, bee swarms and the first wasp nests, then August and September stack peak mosquitoes, wasps and fleas on top of scorpion season. If you only prepare for one stretch, prepare for late summer. The calendar above shows both waves.
When do fire ants show up in new Round Rock sod?
Often the first spring after it is laid. New sod frequently arrives with fire ant colonies already in it, and cleared limestone in Teravista, Behrens Ranch and the other new sections pushes displaced colonies toward fresh lawns. Mounds surface after rain, with peaks in April and May and again in September and October.
When is mosquito season in Round Rock?
Brushy Creek keeps breeding water through town all summer, so figure May through October with the worst of it in August and September. The mosquito add-on brings the general plan to $166 per month and is built around exactly that window.
When do roof rats move into Round Rock attics?
October through January, as soon as nights turn cold. The mature canopy along Brushy Creek in Forest Creek and Stone Oak gives roof rats a highway to the roofline. If you heard scratching last winter, the sealing work should happen in early fall, before they move back in.
