West Indian Subterranean Termite (Heterotermes spp.)

Subterranean termites are by far the most destructive species of termites.

Where do they live?

Mud tubes descending from overhead often reveal the presence of these termites. These tubes are found in crawl spaces, basements, and in the ceiling rafters of homes. The termites also make holes in sheetrock which they cover with dirt and faeces.

They nest in soil, trees and wooden structures and can attack any structure through the mud tubes they build to connect their nests to wood. Since they’re either underground or hidden in wood, they are hard to find and identify.

How do they live?

The average queen produces at least 100 eggs per day and she can live for as long as 25 years. The other members of the colony may live anywhere from 1 to 2 years.

How do they affect us?

Billions of dollars are spent every year to repair the damage they cause.

How do we control them?

It is important to keep structural lumber from direct contact with soil. Keeping the lower foundation walls and siding clear of vegetation makes it easier to inspect for termite shelter tubes. Subterranean termites need moisture for survival.

Leaky plumbing, air conditioning condensate, and any area that has a lot of moisture should be corrected.

Pre-construction treatment can be done before buildings are constructed.
