How often should PT 221L Residual Aerosol be applied?

Once it dries, I'm wondering how long it is effective before it needs to be re-applied. Also, how long does it take to dry indoors so I know how long to keep kids and pets out of the house?


Reapplication of PT 221L Residual Aerosol may be made at 7 day intervals. Pets and children can return to the treated areas once the application is dry, which may be around an hour.
