How to treat for German roaches in tricky places...

The German roaches seem to like doors best. I find them collected along the top or sides of the shut door and when I open it they scatter in all directions. This is especially bad in the entry doors but also in interior doors that are not opened regularly. Any suggestions on how to treat these areas with pesticides? I do have on hand Demon WP and Suspend SC. I have tried spraying Cy Kick which will kill on contact but is supposed to have residual effect but I'll find roaches in the same place happy and alive a week later.


Demon WP and Cy-Kick Aerosol will treat roaches but we do not recommend that these products be used as the sole treatment for this species of roaches. We recommend that you use our Roach Control Kit #1 in addition to a residual spray like Demon WP for indoor treatment of german roaches.

For around the door frames you can spray either the Demon WP or Suspend SC, the roaches can still be seen there but they will die after contacting the area that either product was applied to.
