A type of powder made from the sediment of fossilized algae found in bodies of water, diatomaceous earth (DE) is used in multiple ways:
Indoor Pest Control. DE removes the waxy outer layer of insects’ exoskeleton which helps them maintain moisture, thus causing them to dehydrate. Use it on carpets, upholstery, or anywhere else you think bugs or pests may be lurking. Brush or vacuum the area first, then spread a light film of DE over the whole surface. Leave it for 4-12 hours and then vacuum. Repeat weekly for 3-4 weeks.
Natural Garden Pest Control. DE is best used dry. Lightly sprinkle it where slugs, Japenese beetles, or other unwanted pests will come in contact with it.
Food Preservation. Mix a small amount of DE in with dry grains, legumes (about 1 tablespoon in a 5-gallon bucket of grain) to prevent weevils. If you've ever had weevils you know how frustrating they can be to get rid of!
Skin Exfoliation. DE can be a great exfoliator every once in a while. Use it as part of a facial scrub or mask by mixing 1 tablespoon with water, milk, or diluted honey to make a thick paste. Massage it into your face in circular motions and let it set for 1-2 minutes before removing with a warm washcloth, again in small, circular motions.
Animal Health. DE is helpful for keeping unwanted pests away from your animals. Include DE in your chickens’ dust bath to prevent lice or in your animals’ feed as a natural way to fight off fleas, worms, and other parasites. You can also give your indoor pets (or their beds) a light dusting to help fight against fleas and allergies.
