What's the best way to keep...

Sprinkle boric acid powder under appliances, behind the refrigerator, under counters, and in any other places that are out of the reach of children and pets. The roaches will step in the boric acid and ingest it when they groom themselves (yes, they do groom). Roaches love the area under the refrigerator — especially the drip pan and motor — so vacuum up dirt and dust and wash the drip pan often. You can also make a trap with a glass jar about four inches high. Put some bacon grease and a small chunk of banana at the bottom. Smear a band of petroleum jelly about three-quarters inch wide around the inside of the jar, about one-half inch from the top. Stand it in an area where roaches are a problem. The bugs can crawl in but not out. A common passageway for roaches is through the holes for the plumbing under the kitchen sink. Plug these tightly with rags, and you’ll stop the roach traffic there.
