    Q
    Which product would successfully eliminate American cockroaches?
    We just moved to Texas, and bought our first home. We have these cockroaches INSIDE our home that fly. We were told they are called American cockroaches, but they look like something out of a childhood nightmare. Please recommend a product that we can purchase to use with a sprayer, that would be most effective for central Texas American cockroaches.
