Where to Put Boric Acid Roach Baits and Recipe Question
I've been trying to make boric acid roach baits with boric acid, flour, grease (can you use used vegetable oil or does it have to be meat drippings?), and recently white sugar. But the roaches don't appear to be interested, I've put them at the outer corners inside the kitchen cabinets because I think that's where they are hiding, do they need to be closer to the wall to be more effective? Also the boric acid baits hopefully will take out any hidden nests.
