Another idea that may have its uses: once you are carrying a super bright tactical light in your left pocket all the time, you can take it out anytime you like, it’s just a light, about 6” by 1” diameter. See some dark areas up a 100’? Light it up. Cockroaches hate the light. They thing the cops are out patrolling. It makes them fade. Or it shows them at a distance that works for you and not for them. All they see is the bright light, they can’t see you. You could be a pair of cops. They don’t like lights, and there is no law against shining bright lights into dark places at night.
EXCELLENT
