Precor IGR Concentrate is a great IGR labeled for fleas, but it is not for use outdoors as it is not photo-stable. If you are treating for fleas outdoors you can use our Outdoor Flea and Tick Kit. This kit contains professional products to help prevent and treat infestations of fleas. Cyzmic CS is a versatile insecticide concentrate with two active ingredients, providing both a quick initial kill and long-term residual control of adult fleas. Archer Insect Growth Regulator prohibits the development of immature stages of fleas, effectively interrupting the breeding cycle of target insects. These concentrates can be diluted and applied together to save time and energy. Most of your flea control will come from the initial application, but it may take several treatments to fully eradicate a or flea population. For heavy infestations, you would want to reapply after 14 days to catch new adults that have emerged or insects that animals have carried into the treatment area.
