The composite insecticide composition may further contain at least one of a solvent and a propellant. The weight percentage of each of the active ingredients may be about 0.05% to 0.5%. ## Claims ### Claim 1 A composition for killing insects, the composition comprising: between 0.05% to 0.5% by weight of transfluthrin;
