Bees Near AC Units and Outdoor Fixtures

AC covers, pipes and sheltered fixtures make attractive nest sites.

The short answer

Bees and wasps nest in AC outdoor units, covers, ducts and pipes. Switching the unit on can provoke an attack. Check before use, keep distance if you see activity, and call a professional. Protect openings with mesh to prevent nesting.

Why there

• Sheltered, warm spaces.
• Quiet, undisturbed during off-seasons.

What to do

1. Inspect before using the AC.
2. Don't run the unit if insects are inside.
3. Call a professional.
4. Install mesh over openings.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
