Rodent seals can help close small gaps around garage doors that might otherwise allow mice, insects and other unwanted pests to enter. By creating a closer barrier between the door and the surrounding surface, they can reduce potential entry points. Seals can also help reduce the amount of rainwater, leaves, dirt and draughts entering the garage.
But which type of seal should you choose, and how can you check whether your garage door needs one? Here’s what to look for and how rodent seals can help.
HOW DO PESTS GET INTO YOUR GARAGE?
Garages can provide shelter for pests, particularly when there are accessible gaps around doors and other openings. Even if a garage door looks closed, uneven flooring or a worn seal can leave spaces underneath.
COMMON AREAS TO CHECK INCLUDE:
- Gaps beneath the garage door: Spaces between the bottom of the door and the floor can provide an entry point for small pests.
- Worn or damaged seals: Older seals can deteriorate or become damaged over time, leaving gaps and openings that were previously covered.
- Uneven garage floors: An uneven floor surface can make it difficult for the garage door to close tightly along its full width.
- Gaps around the door frame: Small openings around the sides or top of the garage door may also provide potential entry points for pests.
HOW CAN RODENT SEALS HELP PREVENT PEST ENTRY?
Garage door seals work by reducing the open spaces between the garage door and the surfaces around it. These gaps can sometimes be difficult to notice, particularly along the bottom of the door where the floor may not be completely level. Even a relatively small opening can create a potential access point for insects and other small pests.
A suitable seal creates closer contact along these areas, making it more difficult for pests to enter through the garage door. Depending on where the gap is located, this could include a rubber garage door seal, a floor threshold seal or a brush strip. Flexible brush strips can be particularly useful where the surface varies, as the bristles can follow small changes in the surface.
Rodent seals should not be considered a complete pest-control solution, but they can form an important part of reducing potential access points around the garage.
HOW TO CHECK YOUR GARAGE FOR GAPS:
Checking your garage door can help you identify potential entry points before they become a bigger problem. If you’re looking to rodent proof your garage door, checking for gaps is an important first step.
- Close the garage door: Look along the bottom edge to see whether there are visible gaps or daylight coming through.
- Inspect the existing seal: Check for cracks, wear or sections that have come loose.
- Check the floor: Look for uneven areas that may prevent the seal from making consistent contact.
- Inspect the door frame: Check around the sides and top for other openings that may need sealing.
If you find evidence of an existing infestation, sealing gaps should be part of the solution rather than the only action you take.
WHAT ELSE CAN YOU DO TO REDUCE PESTS IN YOUR GARAGE?
Door seals can help close potential entry points, but a few additional measures can make your garage less attractive to pests.
- Store food securely: Keep bird seed, pet food and other food items in sealed containers.
- Keep the garage tidy: Reduce clutter where pests could shelter or nest.
- Remove rubbish regularly: Avoid leaving waste or food scraps accessible.
- Check other openings: Inspect vents, pipe openings and gaps around windows or other doors.
