Penetration of Termiticide Treatments into Gravel Used as a Construction Fill Material

Abstract

The penetration of five termiticidal suspensions (Termidor, Premise, Talstar, Phantom, and Transport) was examined in packed columns in the laboratory, in which each column incorporated a top gravel layer and a lower soil layer. This simulates common building practices in some parts of the United States. The highest doses were usually found at the top of the soil layer beneath the gravel, indicating that the applied suspension (at either the normal labeled volume or a higher volume allowed for treating gravel) penetrated to the soil below at levels sufficient to kill termites (Isoptera: Rhinotermitidae). The active ingredients were retained by the gravel in lower amounts, with the highest concentrations usually detected in the top 2.5 cm of the gravel.
