Wildlife Problems in San Antonio, TX

San Antonio, TX, is the second most populated city in the state. As such, it attracts a number of wildlife pests that thrive in urban settings. Residents encounter everything from rodents and bats to small mammals and predators in their backyards and attics.

Q&A with Local Franchisees Russ and Lynne Van Hellen:

What are some of the most common wildlife issues that homeowners face in San Antonio?
Raccoons, squirrels, opossums, rats and bats in attics, between floors, in chimneys or vents. Noises between floors, in walls or the attic. Skunks and armadillos digging in yards, flower beds or gardens. Bees in the attic, wall or chimney.

How do the seasons affect wildlife activity in your area?
Hotter seasons generally have less animal activity in the attic. Rodents can be found year-round in the attic. Skunks and armadillos are very active with digging in the yard/flower beds in the summer season. Fall and spring bring baby season, and there is an increase in wildlife moving into attics.

What are some common signs of nuisance wildlife activity?
Digging in the yard or flower beds. Noises and scratching in the attic and walls. Finding droppings, chewed wires in the attic, or torn insulation. Smelling odors inside the house. Vents screens are pulled away or missing from the vent.

Any prevention tips for residents in your area?
Don’t feed wildlife. Keep your pet food in animal-proof containers (not plastic) and don’t leave your pet food unattended outside. Make sure garage doors are closed in the evening. Keep trees and bushes trimmed around your house. Remove any brush or wood piles. Don’t feed the birds. Make sure there are no open holes where an animal can get inside your attic. Call Critter Control to inspect your home for animal entry and have us seal every hole or entry point.

When should homeowners call Critter Control?
As soon as they hear a noise or scratching in the attic, walls or between floors. Also, as soon as they see any droppings inside the house or attic, or if insulation has been removed.

Typical Wildlife Services in San Antonio

Squirrel Damage

As rodents, squirrels have teeth that grow constantly. To manage the length of their incisors, the pests gnaw on hard objects. They climb onto roofs to gain entry to attics. Indoors, a squirrel will target wooden support beams, siding, and even wiring in walls. This behavior causes structural damage and puts San Antonio homes at risk for fires.

The Complexity of Bats

In Texas, state law protects several endangered bat species. However, they still pose a threat to residents when they roost in buildings. In addition to being rabies vectors, bats can spread histoplasmosis. Their urine and droppings also stain surfaces and create strong odors.

Raccoon Versatility

As omnivores, raccoons have a varied diet. They often forage in trash cans, causing headaches for San Antonio homeowners who wake up to garbage strewn across their lawns. A raccoon has no trouble finding a denning site, either. Anywhere warm and secure, like a chimney or an attic, will do. Once inside, raccoons may breed, spread fleas and tear up insulation or wiring.

Rodent & Rat Control

The rapid expansion of San Antonio is the ideal breeding ground for commensal rodents like Norway and Roof Rats. They thrive on human activity, while spreading diseases like leptospirosis, tularemia, Hantavirus and plague. Roof rats are capable of squeezing through holes only ¾” in diameter. Rat infestations can also be heard at night in the attic, making scratching and running sounds. Once inside homes, they gnaw on wooden beams and wiring in walls, causing structural damage and the risk of electrical fire. 

Other Urban Nuisances

Texas residents may also suffer skunk infestations in yards. Like raccoons, the pests seek out safe places to nest and often burrow under porches or decks. Skunks dig cone-shaped holes in lawns to look for grubs, as well.
