I need a product that works for fleas.
Gentrol Aerosol is not labeled for fleas. We recommend using Ultracide. Ultracide Spray contains Permethrin and Phenothrin to kill adult fleas fast. It also contains Methoprene (an insect growth regulator) to prevent reinfestation for up to seven months. It is our recommendation and industry standard that you vacuum immediately before the application of Ultracide and every day or every other day after the application for the next two weeks. Most folks need to do a follow up application after two weeks to get rid of any stragglers. You should also treat all pets that may have fleas with a product that is labeled for use on animals.
