Archer IGR should be used every 10-14 days when treating for fleas. We would also recommend that you use an insecticide in combination with this product for fleas, such as Temprid SC. Both of the products will be used every 10-14 days. Be sure to vacuum daily in between treatments as well. Please see our Flea Treatment Guide for more tips and information.
