I have a couple of wasp / yellowjacket nests that need to go. I just tried every "off the shelf" poison the Depot carries. These things brushed it off like "you and your horse buddy....get that weak s*** outta' here". Years ago (8-9?) the Depot used to carry a spray that they kept in the roofing supplies section.....loved that stuff...if you hit a wasp with it...down they went....can't find it now at my local D. So ... what poison / spray do I need to get ? Any of you roofing / construction guys have a "go to" spray that works? (Amazon links would be awesome) I just want these things DEAD....especially the one that nailed me.....sting still itches three days later.
