Mulch and method for killing termites

摘要

A mulch for poisoning termites without poisoning the soil includes wood chips and/or tree bark impregnated with a borate salt. The mulch is placed in contact with the soil near a termite infestation or near a termite-attracting feature. The mulch is impregnated preferably with a sodium borate salt, such as disodium octaborate tetrahydrate or disodium tetraborate decahydrate.
