Hello! How good to see a homemade remedy instead of a horrible pesticide. When I moved into my house there were roaches! Ugh! I spent a year squeezing boric acid into every crack nook and cranny. Sealing up after with calk. Dusted shelves with boric acid, working into the seams with a paint brush. A lot of work. But it did work! Haven't seen a live Roach in the house probably for 20 some years! These baits will help anyone fighting an insect battle as the boric acid drys the bug like a mummy, without the dreadful pesticide dangers.
