Termite foraging during the summer can include tunneling in the soil close to the surface - especially in favorable locations, such as under bark mulch and stone and gravel ground covers. Soil temperatures and moisture under these materials can be favorable for termite foragers, which require moist conditions.

Termites might feed a little on the mulches we use around our homes but mulch has no nutritional value to them and they will quickly look for something else. However, mulch around homes (including bark mulch) can provide termites a bridge over termiticide-treated soil and access to structural wood. Research suggests that gravel mulch can also create a favorable environment during the summer. Under this material, termites can spend time feeding on roots and construction debris. While gravel provides some ideal conditions, it has been found to be more effective than bare soil in keeping termites away from homes.
