Why do wasps nest in garage door seals?
The gaps in garage door weather seals and along the bottom threshold make an appealing nesting spot for wasps and other insects every GTA summer. Left alone, a nest can damage the seal and make it harder for the door to close properly. Weather seal replacement typically runs $120–260.
Why do wasps like garage door seals specifically?
The narrow gaps along a weather seal or bottom threshold offer a sheltered, protected space — exactly what wasps and similar insects look for when choosing a nest site.

Why garage door seals attract insects every summer
The rubber or vinyl weather seal along a garage door's bottom edge and sides is designed to compress and flex — which also means it has small gaps and pockets that make an attractive, sheltered nesting spot for wasps and other insects during the warmer months. It's a common, seasonal issue across the GTA, not a sign of anything wrong with the door or seal quality.
What a nest actually does to the seal
| Stage | Effect on the door |
|---|---|
| Early nest activity | Minimal effect yet, but worth addressing before it grows |
| Established nest | Seal may not compress evenly, leaving gaps for drafts and debris |
| Nest removed, seal damaged | Section may need patching or full seal replacement |
Safety first
A small, freshly started nest may be manageable to remove yourself with appropriate precautions, but an established or clearly active wasp nest near a door your household uses daily is worth having a pest control professional handle. Once the nest is safely cleared, the seal itself can be assessed and repaired or replaced.
Signs to watch for
- Visible insect activity around the bottom or side seals, especially in early-to-mid summer.
- A gap along the bottom of the door that wasn't there before.
- Draft, light, or debris getting in along one section of the seal.
Royal Garage Doors recommendation
Once any pest issue is safely resolved, a proper weather seal replacement restores a clean, even seal along the full door. See our full pricing page or book a free assessment.
Frequently Asked Questions
Why do wasps like garage door seals specifically?
The narrow gaps along a weather seal or bottom threshold offer a sheltered, protected space — exactly what wasps and similar insects look for when choosing a nest site.
Is it safe to remove a wasp nest near my garage door myself?
For a small, newly started nest it may be manageable, but an established or active nest is safer left to a pest control professional, especially near a door you and your family use daily.
Can a nest actually stop my door from closing properly?
Yes — a nest built into the seal can prevent it from compressing evenly, which sometimes shows up as a gap along the bottom of the door or the door not seating fully.
Does a damaged seal need full replacement or can it be repaired?
It depends on the extent of the damage — a small section can sometimes be patched, but a full weather seal replacement is often the more lasting fix once a seal has been compromised.
How can I prevent this next summer?
Regular visual checks along the seal during summer, and prompt removal of any early-stage nest activity, are the most effective prevention.
