Abstract
The specification discloses an insecticidal bait composition for cockroaches and a related method of its use for the control of cockroach infestations. In general, the composition contains boric acid in an amount of from about 15 to about 40 weight percent together with attractant foodbaits for attracting the roaches to the composition so they will consume it. A preferred composition effective for use by persons such as typical homeowners who are not specially trained in the use of insecticides contains between about 15 and 20 weight percent boric acid along with foodbait attractants. Compositions according to the invention containing unconventionally low amounts of boric acid combined with masking foodbait attractants promote control of cockroach infestation by encouraging direct ingestion of the insecticide, and also have an initial surface-adherent paste or gel-like consistency which enables the material to be applied to cracks and crevices where it hardens and remains for long periods of time for prolonged effectiveness in controlling infestations.
