Rodent Removal in Houston and San Antonio

Hearing scratching in your attic or spotting droppings in the kitchen? Rodents are more than just a nuisance—they pose serious health and safety risks. At Critter One, we provide safe, humane, and effective rodent removal in Houston and San Antonio, and surrounding Texas communities.

With over 25 years of experience, our team knows how to stop rodents at the source and keep them out for good.

Common Signs of a Rodent Problem

If you live in Houston or San Antonio, here are signs that rats or mice may have invaded your home:

• Scratching, scurrying, or squeaking noises in walls or attic
• Droppings in pantries, closets, or along baseboards
• Chewed wires, furniture, or insulation
• Nests made from shredded paper or fabric
• Unusual pet behavior or foul odors

Rodents like rats and mice can spread disease, contaminate food, and cause electrical fires by chewing through wiring. If you’ve noticed any of these signs, don’t wait—contact us today for a free inspection.

How We Permanently Solve Rodent Problems

Finding a rat or mouse in your home is only part of the problem. Simply trapping the rodents that are inside today doesn't prevent new ones from entering tomorrow.

At Critter One, we focus on solving the entire problem—not just removing the animals you can see. Every rodent inspection is designed to identify how rodents entered your home, where they're nesting, and what it will take to keep them from returning.

Whether you've heard scratching in the attic, found droppings in the pantry, or noticed chewed wiring, our process addresses both the immediate infestation and the conditions that allowed it to happen.

• Thorough Inspection – Every project begins with a comprehensive inspection of your property, including the attic, roofline, crawlspace, garage, and exterior. Our technicians identify active rodent activity, nesting areas, contamination, and every potential entry point.
• Rodent Removal – Once the inspection is complete, we safely remove rats or mice using professional trapping and removal techniques appropriate for your home. Our goal is to eliminate the active infestation as efficiently as possible.
• Rodent Exclusion – Removing rodents without sealing the home often leads to repeat infestations. After removal, we seal vulnerable entry points using durable materials designed to prevent rodents from getting back inside.
• Sanitation & Attic Restoration – Rodents leave behind droppings, urine, nesting materials, and contaminated insulation. When needed, we sanitize affected areas and provide attic restoration services to help return your home to a clean, healthy condition.
• 15-Month Guarantee – Our full home exclusion service is backed by a 15-month warranty.

Common Places Rodents Invade Your Home

FindRodents can enter homes through surprisingly small openings and often remain hidden for weeks before homeowners realize there's a problem. Knowing where rodents commonly live can help identify an infestation early.

• Rats or Mice in the Attic – The attic is one of the most common locations for rodent activity. Homeowners often hear scratching or running noises after sunset as rodents search for food or build nests. Left untreated, rodents can damage insulation, chew electrical wiring, and contaminate attic spaces.‍
• Rodents Inside Walls – Scratching, squeaking, or movement inside walls often indicates rodents traveling between nesting areas and food sources. Because wall voids are difficult to access, professional inspection is usually necessary to determine where they're entering the home.‍
• Rodents in Garages and Storage Areas – Garages provide shelter, stored food, pet food, cardboard boxes, and clutter that rodents use for nesting. Small openings around garage doors or utility penetrations frequently become entry points.‍
• Rodents in Crawlspaces – Crawlspaces offer warmth, protection, and easy access to plumbing and utility lines. Moisture and limited human activity make these areas attractive nesting locations if openings are left unsealed.

Frequently Asked Questions About Rodent Removal

How do I know if I have rats or mice in my home?

Common signs of a rodent problem include scratching or scampering sounds in the attic or walls, droppings, gnaw marks on wood or wiring, nests made from insulation or paper, and unusual odors. If you notice any of these signs, it's best to schedule a professional inspection before the infestation grows.

Will trapping the rodents solve the problem permanently?

Not usually. Trapping removes the rodents currently inside your home, but it doesn't address how they got inside. Without identifying and sealing entry points, new rodents can enter and create the same problem again. That's why we combine removal with professional rodent exclusion whenever possible.

How do rodents get into homes?

Rats and mice can squeeze through surprisingly small openings around rooflines, vents, utility penetrations, garage doors, foundation gaps, and damaged siding. During our inspection, we identify potential entry points and recommend the best long-term solutions to help keep rodents out.

Do I need to replace my attic insulation after a rodent infestation?

Not every home requires new insulation. However, if rodents have contaminated the insulation with droppings, urine, or nesting material, replacement may be recommended to restore a clean and healthy attic environment. Our team will explain your options after completing the inspection.

How long does rodent removal take?

Every infestation is different. The timeline depends on the severity of the problem, where rodents are nesting, and whether exclusion work is needed. After inspecting your home, we'll provide a clear treatment plan and explain what to expect throughout the process.

Do you offer a warranty on rodent services?

Yes. Our full-home rodent exclusion service is backed by a 15-month guarantee, giving homeowners confidence that the problem has been addressed correctly. During your inspection, we'll explain which services qualify for our guarantee and answer any questions about coverage.
