How to treat termites in the ceiling

"There's some damage to my ceiling, and I think it might be termites. How can I tell, and should I be worried?"

If you're seeing signs of termite damage to your ceiling, it usually means the infestation has been active for a while. Termites don't typically start at the ceiling; they work their way up from the ground or through wall voids.

Common signs of termites in your ceiling include sagging or discolored patches, small holes, or piles of frass (droppings) resembling sawdust on the floor below. Ceiling damage suggests the colony has had time to spread, and the structural wood may be compromised.

However, some of these signs can be caused by other issues, so it’s best to get a professional to check.

What should I do if I find termites in my ceiling?

If you see signs of termites in or around your ceiling, avoid disturbing the area. Try to document what you're seeing with photos if possible. Don't attempt to remove damaged wood or spray anything until a termite control professional has assessed the situation.

Why are termites in my ceiling?

Subterranean termites build mud tubes to travel from the soil to wood sources above ground. They may move through wall voids, attic spaces, or along plumbing and electrical lines to reach ceiling joists.

Drywood termites can infest wood directly and don't need contact with soil. They may enter through roof vents, eaves, or cracks in the attic and work their way into ceiling beams.

Both types can cause serious damage if left untreated.
