HARRIS FOOD GRADE DIATOMACEOUS EARTH
Harris Food Grade Diatomaceous Earth (DE) is composed of 100% ground freshwater DE, with no additives. The product is made of the naturally occurring fossilized remains of diatoms, a type of algae that forms in freshwater.
Our DE is mined in northwestern Nevada, near the California border. The DE deposits came from the western side of the Pleistocene era Lake Lahontan.
WHAT IS DIATOMACEOUS EARTH?
A diatom is a one-celled plant, so tiny that it must be magnified thousands of times to be seen. Diatoms take the minerals out of the water and build a protective shell. As they die, the shells drift to the bottom of the ocean or lake bed and form thick layers of Diatomaceous Earth (DE).
P.F. Harris Manufacturing, Inc. relies on nothing but the best supplier for Diatomaceous Earth. Their mining operations have more than 40 years of experience and is known worldwide for using a grade and quality of Diatomaceous Earth that is extremely pure.
It was important to have a consistent shaped diatom and no unwanted sediment. The shape of the diatom must be tubular with holes on the walls. It must be fresh water because the diatoms form a harder shell and are less fragile that those in salt water. Salt water deposits contain a mix of diatom species. These deposits shapes and sediments are inconsistent, making them unusable for our products.
How to Use Diatomaceous Earth for Fleas
Diatomaceous earth (DE) is an excellent insect killer that is both nontoxic and long-lasting. It has long been used in the control of fleas, bed bugs, ants, and other household pests.
Diatomaceous earth is a naturally occurring powder that is made from the microscopic remains of a type of algae, known as diatoms. The shells of diatoms are made out of silica, which is mined from ancient freshwater lakes and then crushed into a fine powder. This powder is soft to the touch of humans, but has microscopic razor-sharp edges that will kill insects, such as fleas.
Instead of poisoning the fleas, diatomaceous earth cuts their hard exoskeleton (outer shell) leaving them vulnerable for moisture loss. DE is highly absorbent and will then suck the moisture away from the pest until it dies of dehydration. After coming in contact with the diatomaceous earth, fleas may die in as little as 4 hours, though it is recommended to leave the DE for up to 48 hours to ensure its effectiveness.
Application Tips for Flea Control
Diatomaceous earth can be used indoors or outdoors, and will remain effective as long as it stays dry. It is safe to use around pets and humans, but since it is a dust, you should still try to avoid having it blow around, as it may be slightly irritating.
Start by locating the areas in your home or yard where you have seen fleas or your pets spend a great deal of time. Places to consider may include: furniture, pet beds, floors, cracks and crevices, under sinks, and even in gardens. If infested areas consist of carpeting, bedding, or other textiles, you may want to give it a good vacuum first to get the fleas moving.
Next, sprinkle the DE powder over the surfaces you want to treat. You want to apply it in a thin, uniform coating. If you are applying it to carpet, work it into the carpet using a broom to ensure that it gets deep into the fibers. If the areas are hard to reach, you can use diatomaceous earth in a duster or puffer bottle.
Leave the powder for a day or two so that it can do its job. Then thoroughly vacuum up the powder and dead fleas. If the treated area is out of the way, it can be left there as a preventive measure, and it will be effective as long as it stays dry.
Repeat this process once a week for 3 or 4 weeks to ensure that all eggs have hatched and adults and nymphs have been exterminated.
Diatomaceous earth is great for flea control because it is safe and easy to use. Also, since it is a mechanical killer, fleas will not develop immunity to it. Use a quality diatomaceous earth for best results, and avoid using DE that is labeled for pool and aquarium use, as it has been chemically treated and can be dangerous if inhaled or ingested. If you are struggling with fleas, give diatomaceous earth a chance. Trust Harris products for all of your pest control needs.
