Efficacy of propoxur insecticide strip use in a laboratory animal facility.

A non-fumigant, controlled-release, impregnated strip (insecticide strip) was evaluated for effectiveness against cockroaches (Blatella germanica) in a conventional animal facility. A substantial initial roach mortality was observed in treated rooms. Continued use of the insecticide strip assisted in the control of the cockroach population and did not affect plasma cholinesterase levels of exposed laboratory animals.
