Got creepy bugs and crawling insects like ants, centipedes, cockroaches, silverfish or bedbugs trying to take over your home or garden? Need to know how to get rid of them? Don't call an exterminator quite yet. I'm confident this is a problem you can fix yourself with diatomaceous earth — cheaper and faster!


If you want to treat your home to get rid of centipedes, spiders, ants, silverfish, cockroaches, fleas and all other creepy crawlies but you don't want to poison yourself, your pets or the earth, your very best option is to use food-grade diatomaceous earth.


Diatomaceous earth (DE) is an off-white talc-like powder made of the fossilized remains of marine phytoplankton. If you could take a look at it through a microscope, you'd see that it resembles shards of glass. When sprinkled on a bug that has an exoskeleton (centipedes, ants, cockroaches, bedbugs and fleas) or placed strategically so the bug crawls into it, the DE cuts into the exoskeleton, which causes it to dehydrate and die.


Bedbugs are parasitic insects that feed on blood. They're a nightmare. Bedbugs can enter your home undetected through luggage, clothing, used beds and couches, and other items.

Typically, bedbugs hide in mattresses, box springs, bed frames and headboards where they have easy access to people to bite in the night. Fully grown, a bedbug is about the size of Abraham Lincoln's head on a U.S. penny. Foggers are useless against these ugly critters because they are so good at hiding in places the fog can't reach. Bedbugs are even resistant to expensive professional chemical fumigation!

Diatomaceous earth is the only effective option. It is all natural and safe to use around you and your family.


Here's the most amazing thing about DE: It kills bugs but doesn't hurt mammals. You and your pets could eat it without harm. In fact, many people add DE to their daily diet to promote good health.


Using a flour sifter, a fine mesh strainer, a saltshaker or a pest control bulb duster, lightly dust the powdery DE in cracks and crevices; along baseboards, windowsills and door frames; beneath and behind appliances; in the garden and yard — anywhere you see those little pests. This is a nontoxic and environmentally safe treatment for bugs and insects, but please wear a face protector because it is fine as talcum powder.

For flea-infested carpet, dust the carpet well with the DE, and then pound it in with a broom. Leave it to do its job, and then vacuum the carpet very well after 24 to 36 hours, emptying the bag or dust collector often.


Food-grade DE is readily available at garden centers and hardware stores. Just make certain you purchase food-grade DE, not the variety used in swimming pools, which has been chemically altered and will not work as a pesticide.

One last thing: To do its job as the most effective pesticide ever, DE must be dry. If it gets wet, clean it up, and then reapply.
