Exclusion timing matters most with Mexican free-tailed bats: Texas Parks and Wildlife discourages sealing an attic entry point from about May 1 to August 15, when flightless pups are trapped inside and die.
Mexican free-tailed bats are protected under Texas law and can't be killed, trapped or poisoned. A colony roosting in a Georgetown attic or roofline has to be removed through exclusion, one-way devices that let bats leave and seal the gap once they're gone, and Texas Parks and Wildlife discourages doing that from about May 1 to August 15.

A dropping pile in one spot, directly under a gap in the roofline or soffit, is the most reliable sign of an active roost rather than a bat that wandered in once. If it's building up in the same place night after night, that's a colony using a fixed entry point, and the next step is finding that gap rather than just cleaning up under it.
A dark smudge or rub mark around a gap in the fascia, soffit or roofline is oil and dirt left behind from fur brushing the same edge on every trip in and out. It marks the actual entry point more reliably than droppings alone, and it's usually what a professional looks for first before deciding where the one-way exclusion device goes.
A high chittering or scratching sound around dusk, right as the colony starts leaving to feed, is easy to mistake for birds nesting under the eaves. If it's concentrated at one spot on the roofline and picks up right at sundown rather than through the day, it's the bats moving out, not a bird building a nest.
A sharp ammonia smell in the attic, stronger near one section of the roofline, comes from droppings and urine building up under a roost that's been active for a while. It's usually the sign that pushes a Georgetown homeowner to call, and by the time it's noticeable the colony has likely been there long enough that cleanup, not just exclusion, will be part of the job.
Mexican free-tailed bats naturally roost in the limestone crevices of the Balcones Escarpment, the same fold in the land that runs through Georgetown along I-35. A gap under a roofline or behind a soffit reads to a bat as another crevice, dark, tight, and off the ground, so a house built close to that limestone edge is competing with the terrain the bats already use.
The other driver is how fast Georgetown has built. New rooflines in Wolf Ranch and Sun City go up faster than older ones weather in, and construction along the growth corridors disturbs whatever roosts were already established nearby. A colony that loses one gap in the rock will try the next dark opening it finds, and lately that's been a house.
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.
A general bird or rodent problem in the attic. The test is to crush one: rodent droppings are harder and hold their shape, while bat droppings crumble into a fine powder and often show tiny flecks of insect wings, since bats eat insects and rodents don't. Location matters too — a rodent trail runs along joists and into stored boxes, while bat droppings sit in one pile directly under a single entry point near the roofline.
The licensed pros we connect you with treat a bat colony as an exclusion job, not an extermination. That means finding every entry point around the roofline, soffit and vents, then fitting one-way devices that let the bats leave to feed each night but stop them getting back in.
Once the colony has cleared out through the one-way devices, the remaining gaps get sealed for good, and the accumulated droppings get removed rather than left to sit in the attic. Sealing is what actually stops the problem coming back; a one-way device left in place after the bats are gone is just an open hole.
Ask a Georgetown pest tech which side of I-35 they'd rather work and most pick east without hesitating. West of the highway the ground is thin limestone with cracks running sideways underneath it, which is a different kind of trouble than the dark prairie clay on the east side. Berry Creek and the Serenada area sit right on that seam, and it shapes what shows up at the door more than the calendar does.

Every bat in Texas is protected, Mexican free-tailed bats included, and Parks and Wildlife Code 63.101 covers killing, selling or possessing one. The one exception is a single animal inside a living space, not a colony in the attic, and pesticide, rodenticide or mothballs used against bats is a federal violation. Once the bats are gone, damage and droppings can be cleaned up, but removal stays humane and goes through the licensed pros we connect you with.
Bats don't chew wiring or framing the way rodents do, so a colony doesn't damage a house the same way a rat problem does. The real cost is what a season of droppings leaves behind: soiled insulation, staining that bleeds through a ceiling below the roost, and an odor that doesn't go away until the guano itself is cleared out.
A single bat that's gotten into a living space in Georgetown can be removed without a permit, since Texas law specifically allows dealing with a bat inside a building people live in. Sealing an entire roofline or trying to move a whole colony without knowing where every gap is tends to trap animals inside instead of getting them out, which is where a DIY attempt usually goes wrong.
Bat droppings pile up under a roost and hold moisture, so a colony left in place for a season or more can leave a buildup that needs to be cleaned out, not just covered over. Bats can carry rabies, and anyone who has had direct contact with a bat, or finds one in a room with a sleeping person or a pet, should treat it as worth checking rather than releasing it outside.
Whether it's a roof rat that got into the attic off a tree limb near Berry Creek or crickets piling up under a porch light off Williams Drive, the fix starts with knowing which pest you actually have. The licensed pros we connect you with serve Georgetown and out toward Round Rock and Liberty Hill, and they'll ask the right questions before anyone sets foot on the property. Reach out today and get a straight answer instead of a guess.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.

Texas protects every bat species under Parks and Wildlife Code section 63.101, so nobody may hunt, sell, buy or possess a Mexican free-tailed bat, dead or alive, and that includes a colony living in a Georgetown attic. The one exception covers a single bat that gets inside a home or business people actually occupy — that animal may be removed. A whole colony roosting in a soffit gap near Sun City or Wolf Ranch isn't covered by that exception, which is why the removal method is exclusion, not extermination: sealing the building and letting the bats leave on their own.
Texas Parks and Wildlife discourages excluding a bat colony from about May 1 through August 15, because that's when pups are born and can't fly yet — sealing the entry point during those weeks traps them inside with no way for the adults to feed them, and they die in the attic. If a Georgetown homeowner near Berry Creek or Teravista calls during that stretch, the honest answer is to wait, monitor the entry point, and schedule the exclusion once the pups are flying on their own.
A humane bat exclusion starts with finding every gap the colony is using — usually one main entry point along a roofline, soffit or gable vent — and sealing every other opening on the house first. A one-way device goes over that last gap so bats can drop out and fly off to feed over the San Gabriel River at dusk but can't climb back in. After several nights with no bats returning, that final opening gets sealed too. Nothing is trapped, poisoned or handled directly.
Droppings pile up directly under wherever the colony has been roosting, usually along one edge of the attic near the entry point, and a colony that's been there a while leaves a noticeable ammonia smell along with it. Accumulated guano isn't something to sweep out with a shop vac — it should be cleaned up by someone equipped to do it safely, insulation replaced where it's compacted or stained, and the entry point permanently closed once the bats are confirmed gone.
Georgetown sits on two different soils, split by I-35, and the pest a house attracts depends on which side of that line it's on. That split shapes everything below.
