When treating for bed bugs we do recommend that you treat every 7-10 days until you see no more live bed bug activity in the area. Per the product label on Crossfore Beg Bug Concentrate, you can have residual control and/or kill for up to 4 weeks or 30 days. This begins working within minutes o9f exposure or application.
