Eradicate Flying Cockroaches

There are several methods to exterminate cockroaches. It's wise to employ all methods as it's difficult to get rid of cockroaches once they settle in, especially if you live in a multi-family residence. Unless your neighbors are also exterminating, cockroaches seem to find a way back in.

Determine Where They Are

Find where the roaches hide by performing a survey. This involves leaving sticky traps in drawers, behind appliances, under sinks and in the cabinets. You will also want to do a visual sweep, too. Once you've found the cockroaches' feeding and breeding grounds, you can use chemicals.

Chemical Extermination

Chemical methods use special traps. Baited traps attract cockroaches to feed on poison and are an effective method of eradicating the pests. Sprays and aerosols can be used, but are less effective. Silica aerogel, boric acid and diatomaceous earth are good ways to keep cockroaches away. Apply the dust to cracks and crevices around your home and be sure to include cabinets, closets, baseboards, windowsills, doorframes, and underneath large appliances.

Prevention

Keep your home clean, take out the trash frequently, and store trash receptacles away from your home. Seal cracks and the inside of cabinets and closets with caulk. Repair leaky plumbing and fix structural problems immediately.

Roaches crawl into shopping bags, suitcases, laundry baskets, furniture and boxes. If you have cockroaches when you move, the chances are high you'll bring them to your new location.

Seal opened food in containers. Keep your kitchen and dining areas clean. Sweep up crumbs and clean up spills. Do the dishes daily and wipe down the counters and stove.

If all else fails, contact a professional exterminator to rid your home of the unwanted guests.
