Pest control in Georgetown, Texas
Williamson County's mix of suburban subdivisions, exurban lots, and proximity to the Balcones Escarpment means your pest pressure is whatever the surrounding ecosystem decides — fire ants from a neighbor's untreated yard, scorpions from rocky terrain on the west side of Sun City, subterranean termites that swarm every March or April, and rodents that move in from greenbelt edges in Berry Creek and the rural-edge lots northeast of town. A good pest control program for Georgetown is built around the specific pests in your specific neighborhood, not a generic spray-everything package. This guide pairs with our Best Pest Control directory.
Licensing and what to verify
Texas regulates structural pest control through the Texas Department of Agriculture (TDA) via the Texas Pesticide License (TPCL). Companies that apply pesticides commercially must hold a current TPCL and employ certified applicators. Verify at texasagriculture.gov. Termite work specifically requires a separate certification category (Category 7B). A general pest control TPCL does not authorize termite treatment unless that category is current.
Ask for the certified applicator's name and license number on the contract — not just the company's. Liability insurance and workers' compensation certificates should also be on hand.
Common Williamson County pests
- Fire ants. Best treated in spring (March–April) and fall (September–October) when colonies are active near the surface. Two-step program: a yard-wide bait (Amdro or similar) followed by individual mound treatments. Prevention is far cheaper than allergic-reaction emergencies.
- Subterranean termites. The dominant species in Central Texas. Annual or semi-annual inspections with a termite-certified company are inexpensive insurance. Treatment options: liquid-soil termiticide (Termidor SC, Premise) for active infestations, or bait stations (Sentricon, Trelona) for monitoring and prevention. Texas-typical swarms occur March–May after warm rain.
- Scorpions. The Striped Bark Scorpion is the common Central Texas species. Sun City lots on the rocky west side, foundation-perimeter rock landscaping, and homes with poor door sweeps are at higher risk. Treatment is residual perimeter spray (bifenthrin, lambda-cyhalothrin) plus exclusion work (door sweeps, weep-hole covers, foundation-crack sealing).
- Brown recluse and black widow spiders. Found in attics, garages, and outbuildings — especially in older central Georgetown homes with cluttered storage. Glue boards plus targeted residual spray.
- Rodents. Most common at the rural-suburban interface (Berry Creek, the northeast edge, and rural lots). Roof rats and house mice both occur; field-mouse pressure spikes after major rain events. Proper exclusion work (sealing roofline gaps, weatherstrip, garage door bottoms) is more durable than recurring trapping.
- Wasps and hornets. Paper wasps, mud daubers, and (occasionally) yellowjackets. Spring treatment of eaves and porch ceilings prevents most of the summer pressure.
What a real treatment plan includes
A serious pest control company starts with an inspection, identifies the specific target pests, documents the conducive conditions (entry points, harborage, moisture, food sources), and recommends a multi-pronged approach: residual product applied where it's likely to intercept pests (perimeter, weep holes, around penetrations), targeted treatments for known harborage, and exclusion work to reduce re-entry. Integrated Pest Management (IPM) is the umbrella term for this approach — it costs more than spray-everything but works substantially better and uses far less product.
Treatment intervals vary by program. Most Georgetown homes do well on a quarterly schedule, with separate annual termite inspections and monthly visits during peak pressure (summer ant or fall scorpion season).
Local considerations by neighborhood
Sun City's rocky west side has the highest scorpion pressure in Georgetown — foundation-perimeter rock landscaping, while attractive, is also ideal scorpion habitat. Wolf Ranch and Santa Rita Ranch homes (post-2014) typically have fewer entry points but high fire-ant pressure due to the disturbed soil from recent construction. Berry Creek's mature canopy puts more rodent and squirrel pressure on rooflines. Older central Georgetown homes near the Square often need wasp work in spring and rodent exclusion in fall.
FAQ
How often should I have my home treated?
Quarterly perimeter treatment plus an annual termite inspection covers most Georgetown homes. Monthly is appropriate during peak ant or scorpion pressure or for an active infestation. Indoor treatment is rarely needed if the perimeter and exclusion work is done well.
Are pest control products safe for pets and children?
Modern pyrethroid products (bifenthrin, lambda-cyhalothrin, deltamethrin) have low mammalian toxicity once dry. Drying time is typically 30–60 minutes outdoors, longer indoors. Ask your applicator for the SDS on whatever product is being applied and follow the re-entry interval listed.
What is the difference between a real estate WDI inspection and a regular termite inspection?
A WDI (wood-destroying insect) inspection on a Texas form 25 is the standardized inspection used in real estate transactions, performed by a Category 7B-certified inspector. A regular termite inspection is similar in scope but produces a different documentation form — verify with your lender which form they require.
