Rodent-Proofing Your South Houston Home: A Practical Checklist

Mice can squeeze through an opening about the size of a dime, and young rats need little more than a quarter-sized gap. A home that looks tightly built often has dozens of openings that rodents find easily. Walking the property with a flashlight and a handful of repair materials goes a long way toward keeping them out.

Start Outside

Begin at the foundation and work upward. Look for cracks in the slab or stem wall, gaps where utility lines enter, and loose or missing vent screens. Check the garage door seal at both corners, since worn rubber leaves a visible strip of daylight that rodents use as a doorway.

• Seal small gaps with copper mesh or steel wool packed into the opening and covered with exterior-grade sealant.
• Use hardware cloth or metal flashing for larger holes.
• Install door sweeps on all exterior doors.
• Replace damaged weatherstripping around windows and doors.

Watch the Roofline

Roof rats are skilled climbers that travel along power lines, fences, and tree limbs. Trim branches at least four feet from the roof, and inspect the soffits, gable vents, and roof penetrations for chewed edges or loose covers. Regular exterior visits under our residential pest control program put a technician on your roofline and foundation several times a year, and our crew can point out weak spots during any visit.

Landscape and Yard Habits

Dense ground cover, woodpiles, and stacked boxes give rodents shelter close to your walls. Keep firewood off the ground and away from the house, store pet food and birdseed in sealed metal or heavy plastic containers, and pick up fallen fruit from backyard trees. Outdoor trash cans need tight lids.

Inside the Home

1. Store pantry food in glass or hard plastic containers.
2. Seal gaps around plumbing under kitchen and bathroom sinks.
3. Check behind the water heater, washer, and dryer for openings in the wall.
4. Inspect attic access panels and pull-down stairs for a snug fit.
5. Look for droppings, gnaw marks, and greasy rub marks along baseboards.

Signs You Already Have Rodents

Scratching in walls at night, droppings the size of rice grains, shredded insulation, and chewed wiring all indicate activity. Chewed wires deserve special attention because they present a fire hazard. If you notice these signs, avoid sweeping up droppings dry. Wear gloves, dampen the area, and clean with disinfectant.

How We Help

Sealing keeps new rodents out, while a professional program deals with those already inside and monitors for newcomers. Our rodent control service includes inspection, entry-point guidance, and placement of monitoring stations that our technicians check on each visit. Property owners with larger buildings can look at our commercial pest control options.
