non-porous perimeter

Don't spray on the soil/ground, spray on the hard surface around windows/doors as well as concrete foundation above the soil line.   The goal is to stop bugs from entering the home, not to kill them. 

You've got nothing to lose by doing it this way.

• What they do is to power spay from foundation to 10 feet out. -colorpurple- ♀ (0 bytes) () 09/03/2020 postreply 15:02:30
