Last summer I was having a problem with ants in my garage - mostly in the walk-in door. I tried the ant traps first. The ones I placed inside helped but the squirrels or something stole the ones I had outside. (I found them all over the yard chewed up.) I then tried some expensive spray which smelled amazing but only worked for a few days per application. Then I started playing mad scientist and trying everything in my garage: Simple Green, Windex, ATF, gasoline, etc. I finally got around to trying PB Blaster. Eureka! No ants since. Last fall I built a 6' wood privacy fence. When the weather broke this year, I started seeing ants on the bottom rail. I PB blasted it; no more ants. That was a couple months ago. Yesterday I spotted a convoy of them along the middle rail. They figured out how to climb the neighbor's shrub to bypass the bottom of the fence. Another round of PB Blaster! Anyway, if any of you are able, feel free to help me test this new application for a basic penetrating oil.
