Does wood chip mulch in the yard attract termites?
Monday, October 8, 2018
Contrary to what you may have heard, the answer is an emphatic “NO!” Termites are regularly found under wood mulch around Gainesville area homes, especially in yards with dense landscaping and a sprinkler system that keeps the soil moist. But there is no indication that it “attracts” or “causes” a termite infestation in your home.
Research studies by both the University of Florida and the University of Maryland entomology departments found that, while termites will eat most varieties of wood mulch sold at garden centers while in the process of underground foraging around a yard, it is not their favorite diet; and, the incidence of termites under areas of mulch was found to be no higher than under areas of bare soil or pea rock ground cover. In fact, the University of Maryland study found the most termite activity under pea rock.
Wood chip mulch contributes to a stable, moist soil environment that is good for trees and shrubs. So don’t stop using it. But, because mulch in contact with the base of your home can provide a concealed and protected route for their mud tubes to reach the wood framing lumber of the house, which is their favorite meal, it is recommended that you keep the mulch a couple of inches away from the house or, at least, below the level of any siding.
