A little note about those paper bags that you might not know. My son works in a grocery store. If the store has roaches, and most stores do, even if they spray, they still have roach and mice problems. Anyway, roaches love paper bags. They crawl into them or into the folded cracks, and they also like to lay their eggs in those cracks; and BINGO guess who is taking unwanted guess home with them and don't even know it. Before you know it, you have your own roach problem and wondering how the heck did you get them. It is those brown paper bags from grocery stores.
Just though I would let you know. I had to learn the hard way, before my son ever went work at the store. He just confirmed how I had gotten them and kept getting them no matter what I was doing to get rid of them.
No more paper bags for me, and thankfully no more roaches.
