Diatomaceous Earth (often referred to as "DE") is an off white talc-like powder that is the fossilized remains of marine phytoplankton. When sprinkled on a bug that has an exoskeleton (such as bed bugs, ants or fleas) it compromises their waxy coating so that their innards turn into teeny tiny bug jerky. But it doesn't hurt mammals. We can eat it. We do eat it! It's in lots of grain based foods because lots of grains are stored with diatomaceous earth to keep the bugs from eating the grain! Diatomaceous earth kills all bugs. It has been reported to be the most effective solution when fighting pests like fleas, ants and bed bugs.
Lightly sprinkle dust around the perimeter of the yard or fence. Sparingly apply Diatomaceous Earth around the outside of any kennels or areas where pets rest/sleep. Diatomaceous Earth dust will need to be re-applied after any precipitation. Remember it does not take much dust to be effective and too much dust can be ineffective if it causes a barrier that pests will not walk through.
Internal Parasites can be controlled by giving Diatomaceous Earth internally. It is very important to note that it must be food grade – the earth used in gardens and pool filters can damage your dog. Diatomaceous Earth can eliminate roundworms, whipworms, pinworms, tapeworms and hookworms within seven days of being fed daily. To be most effective, Diatomaceous Earth should be fed for at least 30 days, to catch all newly hatching eggs or the cycling of the worms through the lungs and back to the stomach.
Feed 1 – 15 lbs. ½ teaspoon daily - 16lbs. – 35 lbs. 1 teaspoon – 40 lbs. and over 1 table spoon
In a typical room, 5 percent of the fleas will be found on pets, 10 percent flea cocoons in the carpets, 35 percent flea larvae and 50 percent flea eggs, again in the carpets. Fleas feed on blood, and a flea can live without a blood meal for 100 days.
A female has to have a blood meal to lay eggs. In addition, it lays
eggs within 36-48 hours of having the first blood meal. A female flea can
lay 2,000 eggs in her lifetime. Temperature changes and humidity do effect the flea population. Optimal flea production occurs when the humidity is between 70% and 80% and when the temperature is between 70 and 85 degrees. Understandably, this is why fleas are always a nuisance in warmer climates
