How to Get Rid of Roaches Naturally

When you see roaches in your house, your first thought might be to grab a bottle of insecticide or to call an exterminator. But not only would you be exposing your family to toxic chemicals, they might not do much good.

A study by published in the journal Scientific Reports finds that German cockroaches — the most common roach species found around the world — are becoming harder to eliminate. These disease-carrying insects are developing resistance to many different insecticides, making them nearly impossible to kill with chemicals alone.

Because cockroaches are becoming so close to invincibility, researchers suggest combining chemical treatments with other methods — like traps and better sanitation — when fighting a roach problem. Or you can forego chemicals and try just natural methods.

Getting rid of roaches naturally can be a slow process. But getting rid of them naturally can also prevent the problem from recurring. So how do you do it?

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 counters each night, never leaving dirty dishes in the sink, making sure the stovetop 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 (unless you have a party — or kids — and then cleanup will take a little longer).

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, especially if you live in an apartment and have neighbors who don’t maintain the same standards of cleanliness as you do. You can use a tube of caulk and a caulking gun to do the job.

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.

Make Your Own Natural Cockroach Bait

Mix three parts boric acid with one part powdered sugar. The sugar lures the roaches, while the boric acid 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 and pantries.

Bring in the Experts

If you want to get rid of roaches naturally and you’ve got a big infestation, try contacting a natural pest control company. My pest control company uses a substance called diatomaceous earth in the walls of my home (inserted through the holes around the wall outlets). Diatomaceous earth is a soft sedimentary rock that is easily crushed into a fine powder. It is used in many things (including some medicines and skin care products) but is often used as a mechanical insecticide because it causes an insect to die without the use of chemicals. Look for a pest control company in your area that uses the substance — it’s not harmful for you and your family and best of all, it’s effective.

Keep Your Space As Cool As Possible

The American cockroach is one of the most common cockroaches in New York City. And when temperatures heat up there during the summer, many of these cold-blooded insects also warm up, says Live Science. They increase their activity level and even spread their wings and fly. (Shudder.) "With more heat they have more use of their muscles," the American Museum of Natural History's resident bug expert, Louis Sorkin, told NYC blog DNAInfo.com. While you cannot control the weather, of course, keeping your apartment or home as cool as possible will at least confine cockroaches to the ground.

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. (I keep this stuff around to clean my countertops, by the way.) Because roaches, like most insects, breathe through their skin, the soap essentially suffocates them. Of course, you could just step on it!
