Best Garage Door Seals to Block Rodents & Pests

Nothing is more irritating than discovering rodents have become cozy up inside your garage or shed. Pests like rats and mice are naturally drawn to shelter, which means it’s up to you to protect your property from the persistence of furry invaders. Weather seals for garage doors, sheds, and similar applications are a crucial defense against pests, but not all seal materials can withstand gnawing teeth and claws. That’s why our experts have compiled a list of weather stripping to avoid, and which ones will hold up against rodents and other pests. 

How Do Weather Seals Stop Pests?

Even when closed, garage doors have small openings that pests like rodents can slip through along with debris, rain, water, and other harmful infiltrators. Weather seals provide an inexpensive solution that close these gaps by creating a tight seal between your garage or similar structure and the outside world. Weather seals are an affordable form of pest control in addition to bait stations around problem areas, but only if you install the right kind of seal.

Avoid Installing Cheap Material and Poorly Rated Products 

While any weather seal will provide substantially more protection for an entry point than nothing at all, rodents are able to chew through cheaper seals made from rubber, vinyl, and plastic. Check product reviews for indication that a weather seal material is easy for pests to chew through. If rodents smell food or detect warmth inside of your garage or shed, they’ll be sure to make an entrance and launch a full-on infestation. 

What Are the Best Garage Door Seals for Rodents and Pests?

Steel wool is one of the few materials pests can’t chew through, and RodentBLOCK is a premium yet economically-priced weather seal that exploits this vulnerability. RodentBLOCK is designed with Xcluder®-- a proprietary blend of stainless-steel mesh and strong poly fibers that rodents can't breach. The seal also has an EPDM fin that protects against stormwater, debris, and other containments. 

We carry RodentBLOCK weather seals that are pre-installed with Xcluder® fill fabric, as well as complete kits that include a bottom seal retainer, RodentBLOCK, and a brush seal for additional protection.

Signs Rodents Have Infiltrated Your Space 

Unsure if rodents have already moved into your garage by chewing through your seal? Check around your seal for gnaw or scratch marks around cracks, crevices, and gaps. Fecal droppings and wood shavings can also indicate that rodents have gnawed their way inside of your space, along with gaps and holes as small as 1/4-inch (.635 cm) in diameter, which mice can squeeze through. Call a pest control specialist to get rid of rodents before they cause extensive damage to your property, and be sure to take preventative measures to keep pests out of your garage and vanquish vermin for good! 

RodentBLOCK Life Expectancy and Upkeep

Like all weather seals, RodentBLOCK’s efficiency can dwindle overtime. RodentBLOCK seals can last around 10 years, and potentially more in favorable environments. If you notice light through the seal or any cracks, visible damage or water leakage, it is a good idea to invest in a replacement. Be sure to inspect your RodentBLOCK weather seal at least once a year to check for any issues so you can ensure you have maximum protection.
