My yard and house have fleas and german roaches. After the first treatment how long until I should treat again?
Permethring SFR 36.8% gives you up to a 30 day residual outdoors, and up to a 90 day residual indoors. We would also recommend using an Insect Growth Regulator (IGR) as well for both these pest applications, such as Nyguard IGR Concentrate. This will help stop the reproductive cycle in both the roaches and fleas.
