1. Clean, clean and clean again. As with most household pests, an ounce of prevention is worth a pound of cure. What do I mean? You’ve got to make sure your house is spic-and-span, because cockroaches are attracted to food residue, particularly grease. That means wiping down the sink each night, never leaving dirty dishes in the sink, making sure the stove-top is clean and sweeping the floors before you go to bed. This may seem like a lot to do every day, but if you start doing this stuff on a regular basis, a 15-minute cleanup should be plenty at the end of each night to eliminate most residues.
2. Seal up cracks and holes. That means inside your pantry, between the countertop and the wall, and in the baseboards. Roaches (and other insects) can crawl through even the smallest of spaces, so it’s important to seal the entries into your home. This may take time, but in the end, it’s worth the effort.
3. Fix any water leaks. Roaches are attracted to moisture and water from leaks in pipes. That’s why you often find them scurrying under your sink. Some cockroaches can survive for months without food, but only days without water. Close off their water sources by repairing even the tiniest of leaks. Don’t let water stand in your sink and don’t overwater indoor plants.
3. Kill it with kindness … or just kill it. If you have a cockroach in the house right now and you don’t want to spray harmful insecticides inside your home, try spraying a little solution of soap and water on it because roaches, like most insects, breathe through their skin, the soap essentially suffocates them. Of course, you could just step on it!
4. Make your own, natural cockroach bait. Mix locally made cockroach killer with powdered sugar. The sugar lures the roaches, while the boric acid in the cockroach killer kills them. Although the boric acid isn’t toxic to people or pets, it can be irritating so keep it away from counters and places where little fingers and noses can reach. Sprinkle it under and behind the refrigerator, stove and dishwasher, under the sink, and into cracks along the edges of cabinets.
