Odorous house ants trail indoors year round but surge after rain and through Georgetown's hot, dry summer stretch
Odorous house ants are small, dark brown to black ants that leave a rotten-coconut smell when crushed, common in Georgetown homes when summer drought pulls the clay away from the slab edge. They form large, multi-nest colonies, so bait that travels through the whole trail network works better than spraying what you can see.

A steady line of small dark ants following the same baseboard or counter edge day after day means an established trail, not a one-off wanderer. It's worth tracing the line in both directions before wiping it away, since the direction it runs often leads back toward the entry point and, eventually, the nest feeding it.
A rotten-coconut smell when you crush one of the ants is close to a positive identification for this species, and it rules out most of the other ants that turn up in Georgetown homes. Once that's confirmed, the next useful step is an inspection focused on moisture and mulch near the foundation rather than guessing at bait placement.
Finding ants clustered around a damp spot, like near a slow drain, a sweating pipe under a sink, or the base of a leaking hose bib outside, points to a satellite nest that's moved in for the water. That spot needs drying out as much as it needs treatment, or the ants come right back once the chemical wears off.
A new trail appearing indoors right after a dry stretch breaks or right when a hot spell starts usually means an outdoor colony near the slab is under stress and pushing workers inside. That timing is a sign the infestation is likely coming from just outside the wall it's entering, which is the most useful place to start an inspection before treatment is applied.
Odorous house ants nest shallow — under a slab edge, behind siding, in a mulch bed near Wolf Ranch or Teravista — and a Georgetown summer that pulls the clay away from the foundation gives them a gap straight into the house. They follow that crack in looking for water as much as food.
A wet spring along the San Gabriel River or a irrigated lawn near Berry Creek keeps a colony fed outdoors most of the year, but once the ground dries out the trail moves indoors, usually toward a kitchen sink or a bathroom with a slow drip.
Roof rats outnumber Norway rats in Georgetown, and they get in high rather than low. A limb touching the fascia near Berry Creek or a gap at a soffit line in Teravista does more damage than any crack at ground level, because these rats bridge in from power lines and tree cover and settle into attics and gable vents. Norway rats show up too, but mostly near drainage low down. Checking the roofline first saves a homeowner from chasing the wrong entry point for weeks.
Other small house ants. The clearest way to tell them apart without a magnifying glass is the smell test: crush one, and an odorous house ant gives off that rotten-coconut smell while a carpenter ant doesn't. Location is a second clue, since a trail coming from a damp wall void near plumbing points toward carpenter ants, while a trail coming from a foundation gap or a mulch bed points toward odorous house ants.
The licensed pros we connect you with start by finding where the odorous house ant colony is actually living, since spraying the trail without dealing with the nest just scatters it. Bait formulated for sweet-feeding ants works better here than a contact spray, because the workers carry it back and it spreads through the colony, including any satellite nests hidden under mulch or behind siding around a Georgetown house.
Bait formulated for sweet-feeding ants gets carried back through the whole colony network, including nests a homeowner never finds, and it is paired with a check of slab gaps and siding gaps that a dry Georgetown summer tends to open up.
Drive past a gas station on Williams Drive on a September night and the crickets under the lights tell you the season's turned. It happens on a schedule loose enough to call reliable and tight enough to plan around, and it has nothing to do with anything inside your walls. Cutting the porch light for a few weeks does more good than a can of spray ever will.

Store-bought sprays kill the ants on the counter and leave the nest untouched, and cleaning up a broken trail with soap and water just sends the colony out to build a new route within a day. Sealing an obvious gap under a sink helps, but it will not close every satellite nest a colony can run.
Odorous house ants are not a health risk. They do not bite or sting and carry no known disease risk to people in a Georgetown home. The trouble they cause is contamination of food left uncovered and the sheer persistence of a trail that keeps reappearing.
Scorpions favor the limestone side of town, so a homeowner near Water Oak or backing onto a greenbelt off Williams Drive sees more of them than someone east of I-35. Whichever side you're on, describe what's turning up and where, and a licensed technician working in your part of Georgetown can walk the property and tell you what's actually going on.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 General Pest Control.
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.
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.
Odorous house ants show up in Georgetown kitchens most often in the hot, dry stretch of summer when they come inside chasing water. They trail along counters and baseboards toward anything sweet or greasy. The fastest way to identify them is the smell: crush one and it gives off a rotten coconut odor, which is where the name comes from. That smell test is the surest sign you have this species and not another ant working the same kitchen.
A nest is rarely one nest. Odorous house ants split into many satellite colonies once disturbed, so a colony under a slab edge on Williams Drive or a stack of firewood near Berry Creek can throw off several smaller nests around a foundation. Treating just the trail you can see often misses the rest. An inspection that traces trails back to more than one entry point is usually needed before treatment holds.
Yes, and it happens on both sides of that gap. A dry summer pulls Georgetown's clay soil away from the slab, leaving a gap at the foundation that odorous house ants use to move between mulch beds and the house. That gap tends to reopen after a long drought breaks, which is why a treatment that worked in spring can need repeating once the ground dries out again in July or August.
Not on its own. Odorous house ants nest under mulch, in wall voids, under sinks, and inside potted plants brought in from a porch in Old Town or Sun City, and any of those spots can hold a colony regardless of how the kitchen looks. Sanitation reduces what draws a trail indoors, but the colony itself is outside or in a void, so it takes finding and treating the nest, not just cleaning counters.
Whichever side of Georgetown a house sits on, the licensed pros we connect you with start the inspection at the point that soil actually pushes pests toward the door.
