PURPOSE:The titled transpiring agent to expel cockroaches through growth inhibition or sterilization, obtained by supporting ethyl (2E,4E)-3,7,11-trimethyl-2,4- dodecadienoate on a carrier. CONSTITUTION:Ethyl(2E,4E)-3,7,11-trimethyl-2,4-dodecadienoate(hydro-pr ene) as a active component is optionally blended with an insecticide, a fungicide, a stabilizer, a solvent a volatility adjustor, perfume, a hyestuff, etc., and supported on a carrier, to give the titled transpiring agent. Hydroprene has no immediate effect which an insecticide has, but it inhibits growth of larvae, so cockroaches show appearance of crimping and shortening of feathers, etc., when they become imagoes.
