If you’re hearing scratching in the attic, finding torn soffits, or seeing droppings in the garage, you’re likely dealing with one of Houston’s big three nuisance mammals: raccoons, opossums, or squirrels. The right response is professional wildlife management — humane removal combined with exclusion that seals how they got in — not poison or a hardware-store trap. Here’s how to tell which animal you have, the damage each causes, and why sealing the entry points matters far more than removing a single animal.
How Do I Know Which Animal I Have?
Each of these animals leaves a different signature. Narrowing it down helps you understand the risk and the fix:
- Squirrels are active during the day, and you’ll usually hear fast scampering and gnawing in the attic or walls in the early morning and late afternoon. They leave small gnaw marks, chewed wires, and acorn or nut debris. Entry points are often high — roofline gaps, gable vents, and chewed fascia.
- Raccoons are nocturnal and heavy — you’ll hear louder thumping, dragging, and vocalizations at night. They’re strong and dexterous enough to tear open soffits, vents, and shingles, and they leave large droppings and a lot of damage. A female may be denning to raise young.
- Opossums are also nocturnal, slower, and less destructive, but they den under decks, sheds, porches, and in crawl spaces, leaving droppings and a musky mess. They’re not aggressive, but they can carry parasites and fleas.
What Signs Point to a Wildlife Problem?
Beyond the animal itself, look and listen for the evidence they leave behind:
- Noises in the attic, walls, or crawl space — scratching, thumping, scampering, or vocal sounds, with the timing hinting at the species.
- Entry damage — torn soffits or fascia, damaged vents, lifted shingles, chewed holes, or crushed roof edges.
- Droppings and odor in the attic, garage, or crawl space — and staining on ceilings from urine.
- Chewed wiring, ducts, or insulation, which is both a repair issue and a fire risk with squirrels and raccoons.
- Nesting signs — shredded insulation, gathered debris, or a matted den area, often meaning young are present.
- Fleas or other parasites appearing indoors, dropped by wildlife denning in or under the home.
What Damage Do These Animals Cause?
A wild animal in your home is not just unsettling — it’s expensive. Squirrels and raccoons chew wiring, which causes outages and creates a genuine fire hazard. Raccoons can tear open roofs and soffits, letting in rain and further pests. All three foul insulation with droppings and urine, which then has to be removed and replaced, and their waste raises health concerns. Opossums and raccoons denning under a deck or in a crawl space bring fleas and other parasites right up against the house. And a female raising young means more animals, more noise, and more damage until the whole situation is resolved and sealed.
Why Shouldn’t I Just Trap and Remove the Animal Myself?
DIY wildlife removal backfires more often than it works, for several reasons. First, if you remove one animal but leave the entry hole open, you’ve simply created a vacancy — another raccoon, opossum, or squirrel moves into the same attractive, accessible spot. Second, if there’s a mother with young in the attic and you remove or exclude only the adult, the babies are left behind to die in your walls, which creates an odor problem and a far worse cleanup. Third, cornered wildlife can bite or scratch and may carry disease and parasites, so handling them is genuinely risky. And finally, Texas has regulations governing how nuisance wildlife may be handled and relocated, so this isn’t a free-for-all. Professional management addresses the animal, the young, the entry points, and the cleanup as one complete job.
How Does Professional Wildlife Management Work?
The lasting fix is never just “remove the animal” — it’s remove, seal, and restore. At Sasquatch, the process looks like this:
- Inspection. We identify the species, locate every entry point, and determine whether young are present — which changes the timing and approach.
- Humane removal or exclusion. We remove the animals humanely, accounting for any young, often using one-way exclusion methods that let animals out but not back in.
- Sealing the entry points. This is the step that actually solves the problem. We seal and reinforce the roofline gaps, vents, soffits, and structural openings the animals used, so nothing else moves in.
- Cleanup and restoration. We clean up droppings, remove and replace fouled insulation where needed, and decontaminate the affected area to deal with parasites and odor.
- Prevention advice. We point out the yard and structural conditions attracting wildlife — overhanging limbs, open crawl spaces, accessible food — so the problem doesn’t return.
How Do I Keep Wildlife Away in the First Place?
Prevention comes down to removing access and attraction. Trim tree limbs back from the roof so squirrels and raccoons can’t jump onto it. Cap chimneys and screen vents and gable openings. Seal gaps along the roofline, soffits, and fascia before animals find them. Keep decks, sheds, and crawl spaces closed off so opossums and raccoons can’t den underneath. Secure garbage and pet food, which draw raccoons and opossums in the first place. Most of this is straightforward exclusion — the same work that keeps rodents out — and it’s far cheaper than repairing a full-blown wildlife invasion.
When Should You Call Sasquatch?
Call as soon as you suspect an animal in the attic, walls, or crawl space — especially if you hear it at night, see structural damage, or think young may be present. The longer wildlife stays, the more damage it does and the more likely you are dealing with a growing family rather than a single animal. We handle raccoon, opossum, and squirrel management across Greater Houston, from removal through sealing and cleanup.

Frequently Asked Questions
How do I know if it’s a squirrel, raccoon, or opossum in my attic?
Timing and sound are the best clues. Squirrels are active in daylight, especially early morning and late afternoon, with fast scampering and gnawing. Raccoons are nocturnal, heavy, and loud, with thumping and dragging at night plus significant tearing damage. Opossums are also nocturnal but slower and quieter, and tend to den under decks, porches, and crawl spaces rather than high in the attic. A professional inspection confirms the species and finds how it’s getting in.
Why is removing the animal myself a bad idea?
Because removal without sealing the entry points just invites the next animal into the same accessible spot, and if a mother with young is present, removing only the adult leaves babies behind to die in your walls — creating odor and a worse cleanup. Cornered wildlife can also bite, scratch, and carry disease and parasites, and Texas regulates how nuisance wildlife may be handled and relocated. Professional management handles the animal, the young, the entry points, and the cleanup together.
Are raccoons, opossums, and squirrels dangerous?
They’re generally not aggressive unless cornered or protecting young, but they carry real risks. They can bite and scratch if handled, harbor fleas and other parasites, and their droppings raise health concerns. Squirrels and raccoons also chew wiring, creating a fire hazard, and raccoons can cause significant structural damage. The bigger danger is usually the damage and contamination they cause rather than the animal itself.
What damage can these animals do to my home?
Quite a lot. Squirrels and raccoons chew wiring and can start electrical fires; raccoons tear open roofs, soffits, and vents, letting in rain and other pests; all three foul insulation with droppings and urine that must be removed and replaced; and denning animals bring fleas and parasites against the house. A female raising young multiplies the noise, mess, and damage until the situation is fully resolved and sealed.
How do I keep wildlife from getting into my house?
Remove access and attraction: trim tree limbs back from the roof, cap chimneys, screen vents and gable openings, and seal gaps along the roofline, soffits, and fascia. Close off decks, sheds, and crawl spaces so animals can’t den underneath, and secure garbage and pet food. This exclusion work is the same approach that keeps rodents out and is far cheaper than repairing an established invasion.
What happens to the animals after removal?
We handle wildlife humanely and in line with Texas regulations governing nuisance animals, accounting for any young so nothing is left behind in your walls. Our focus is removing the animals, sealing the entry points so they can’t return, and cleaning up the mess — a complete resolution rather than just relocating one animal and leaving the door open.
