Diatomaceous earth is composed of the fossilized remains of tiny organisms known as diatoms. The edges of these fossilized diatoms are extremely sharp and will lacerate the exoskeleton of nearly any crawling insect that comes in contact with them. Once their outer shell has been lacerated, the powdery DE dehydrates the insect, killing it, although not instantaneously.

While Last Crawl Diatomaceous Earth Insecticides work well to kill most crawling insects, there are a few species that DE is known to be especially effective against. These include:

• Ants

• Bedbugs

• Fleas

• Cockroaches

• Silverfish

• Flour Beetles

• Darkling Beetles

• Grain Beetles

• Centipedes

Is the insect you are looking to exterminate not mentioned above? If the pest is a crawling insect, DE will most likely kill it. Apply food grade diatomaceous earth in the cracks and crevices around your home as well as in other areas where the insects may be hiding. Leave the DE down for a few days to a week and monitor the infestation in order to judge the DE’s effectiveness.
