            Can I use this product with a dog in my house
            ByJul 6, 2024
            1 Answer | 
            Answer This Question

            Thank you for your inquiry. You can use the product with your dog in the house, just remove him/her to a room that is not being treated and do not allow reentry until the product is dry. That takes 2-3 hours.

              Ok to stay inside house while spraing, and it dries?
              ByNov 2, 2022
              1 Answer | 
              Answer This Question

              Have other people and pets out of the room while spraying. All may return when completely dry (approximately 2 hours). Use as a crack and crevice treatment, applied lightly and uniformly until damp, not puddling or dripping. If you intend to spray every room in the house, you may choose to then leave until the spray dries. Thank you. P.F. Harris

                  Thank you for contacting us regarding your experience with Harris® Roach products.
                  The length of time it takes to eliminate a roach infestation can vary depending on how long the roaches have been present and the severity of the problem. In many cases, it may take 3–8 months to fully eradicate them. During this process, you should begin to notice changes such as the roaches becoming smaller in size, which indicates the population is being reduced and progress is being made.
                  We appreciate your patience during the treatment period and remain confident in the effectiveness of our products when used as directed.

                  Didn't have very much in the way of knockdown power. Not sure if it is doing residual killing.
