We apologize you are having such a time eradicating fleas. Fleas control can take time due to their life cycle. Talstar and Archer would work fantastic outdoors and in the garage. The IGR to break the reproduction cycle sounds like what your treatments have been missing. Please view our
Flea control page. If you have a problem indoors, Talstar and Archer can only be applied to cracks and crevices. We recommend using
Alpine Flea insecticide for indoor control.
