Abstract: A process for eradicating termite infestations in a structure and preventing the reinfestation thereof includes the steps of identifying infested wood members, impregnating the infested wood members with a borate solution, and injecting an amorphous silica gel dust into structural voids adjacent to the exterior of the structure. The borate solution, which is applied to surfaces of the infested wood members, kills existing infestations of kaloterme. The amorphous silica gel dust is electrostatically charged as it is injected into the structural voids so as to cling to the surfaces of exposed wood members. This forms a shield against future infestations. Termite barricades impregnated with the borate solution are also inserted into selected wood members of the structure.
