What Romex Seals

Romex Pest Control has over 15 years of experience in rodent exclusion and control across Texas, Louisiana, Oklahoma, and Mississippi. Our technicians are trained in advanced pest exclusion techniques, certified by the National Pest Management Association (NPMA), and equipped with commercial-grade materials that rodents can’t chew through. Here’s what we seal during a professional service:

AC Line Penetrations

The copper refrigerant lines connecting your outdoor condenser to the indoor air handler pass through the exterior wall. This gap is one of the most common rodent entry points in Southern homes. Romex technicians seal these penetrations using a combination of steel wool (which rodents can’t gnaw through) and professional-grade sealant.

Plumbing and Electrical Penetrations

Every pipe, cable, and conduit entering your home creates a potential gap. Romex inspects all exterior penetrations and seals them with appropriate materials, such as expanding foam for larger voids and steel mesh with caulk for smaller gaps. These materials are tested and approved for long-term durability.

Garage Door Seals

The garage door sealant service addresses the bottom rubber, side tracks, and top rail of your garage door. Garages are the number-one rodent entry point in Southern homes, and even a barely visible gap can serve as an open invitation for mice.

Weep Holes

Weep hole screens installed in brick veneer block rodent entry while preserving the drainage function intended by the builder. Unscreened weep holes are essentially open doors into your wall cavities.

Foundation Gaps and Slab Cracks

Where the slab meets the brick veneer, seasonal soil movement—especially in North Texas clay soils—can create gaps large enough for rodents. Romex seals these with durable materials rated for ground contact, ensuring long-lasting protection.

What You Need to Maintain

Once professional exclusion work is complete, maintaining rodent-proof conditions is essential. Here’s what you can do:

Food and Storage

• Store all pet food in sealed containers. A bag of kibble on the garage floor is a rodent buffet. Use rigid plastic or metal containers with tight-fitting lids.
• Keep bird seed in sealed bins. If you use bird feeders, store seed in the house or garage in a sealed container—not in the original bag.
• Don’t leave fruit on counters overnight. Rodents forage at night, and ripe fruit is a high-value target.
• Take kitchen trash out nightly. Especially in warmer months when odors intensify.

Garage Hygiene

• Keep the garage floor clear of clutter. Rodents nest in undisturbed boxes, seasonal decorations, and stored fabric.
• Elevate stored items on shelving—not on the floor against walls.
• Close the garage door fully every night. Even a two-inch gap at the bottom defeats the seal.

Exterior Maintenance

• Keep tree branches trimmed at least 6 feet from the roofline. Roof rats use overhanging branches as highways to your attic.
• Remove ivy or climbing vines from exterior walls—they give rodents hidden pathways to upper-floor entry points.
• Report gnaw marks, droppings, or greasy rub marks to your technician immediately. These signs mean a rodent has found a path we need to investigate.

The Ongoing Partnership

Rodent exclusion isn’t a one-time fix. Homes shift, seals wear, and new construction or landscaping changes can create entry points that didn’t exist six months ago. Your Romex technician checks exclusion work during every recurring visit—verifying seals, inspecting for new gaps, and adjusting as your property changes.

Your part is maintaining the habits that make your home unattractive to rodents. Together, exclusion plus maintenance is far more effective than either approach alone.

FAQs

How often should I schedule rodent exclusion inspections?

We recommend scheduling inspections at least twice a year, especially before and after the colder months when rodent activity peaks.

Are the materials used by Romex safe for pets and children?

All materials used by Romex are tested and approved for residential use. However, we recommend keeping pets and children away from sealed areas during the curing process.

Professional Tip from Romex Technicians

“Rodents are opportunistic. Even if you’ve sealed your home, they’ll test weak points over time. Regular maintenance and vigilance are key to staying rodent-free.”
