A topical insecticide preparation is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. The topical insecticide contains a combination of a first pyrethroid insecticide effective for killing fleas, a second pyrethroid insecticide effective for killing ticks, and an insect growth regulator (IGR). The topical insecticide preparation can be packaged together or packaged so that the first and second pyrethroid insecticides are stored separately prior to administration of the insecticide preparation to the animal. The combination of the first and second pyrethroid insecticides with an insect growth regulator results in an insecticide preparation formulated to have enhanced insecticidal activity against fleas and ticks compared to the effectiveness of the first and second insecticides used alone. Further, the combination of the first and second pyrethroid insecticides with an insect growth regulator produces an insecticide preparation having enhanced insecticidal activity against fleas and ticks while advantageously minimizing the total amount of insecticide needed for its effectiveness.

The present invention discloses one kind of water-based foamed ant repelling and killing spray and its preparation process. The spray is prepared with pyrethroid 0.2-0.5 wt%, foaming agent 5-15 wt%, foam stabilizer 0.5-2 wt%, cosolvent 5-20 wt%, water soluble adhesive polymer 0.1-1 wt%, preservative 0.1-0.5 wt% and water for the rest. Its preparation process includes the steps of: dissolving pyrethroid in the cosolvent to form organic solution A, dissolving the water soluble adhesive polymer and the preservative in water to form solution B, mixing the foam stabilizer separately with the solution A and the solution B, mixing the solution A and the solution B, canning and filling the foaming agent. The ant repelling and killing spray as one kind of active preparation has no toxic organic solvent, simple production process, high use safety, high ant killing effect, environment friendship and other advantages.
