Abstract

Combating wood boring insects comprises burying a layer of plastic mesh (1) impregnated or coated with an active substance such as a growth inhibitor when back-filling a trench excavated to lay or service pipes (2) or cables. The active substance is used to impregnate a substrate containing vegetable fibres such as cellulose, attached to the extruded plastic mesh.
