Unfortunately, Crack and Crevice III has been discontinued by the manufacturer. As an alternative, we recommend Cy-Kick Aerosol which is also a residual crack and crevice aerosol spray.
We have not had any complaints from folks that have had to make the switch from Crack and Crevice III to Cy-Kick. Cy-Kick contains Cyfluthrin, an active ingredient that is known to be effective for even those hard to kill insects such as scorpions, spiders and roaches.
