I have been doing a lot of research on Food Grade Diatomaceous Earth and this is what I have found. Did you know that Food Grade Diatomaceous Earth is environmentally friendly?!?! Did you know it will kill all kinds of house pests/insects INCLUDING fire ants?!?! It will kill roaches, ants, beetles, etc... Just sprinkle it into cracks and crevices or apply directly to ant mounds. Did you know that it will kill internal parasites/worms in dogs, animals, and humans?!?! I am going to include a link that will help you determine how much to administer. Did you know that it will repel lice, ticks, fleas, and chiggers?!?! Did you know that it will make your coop smell better?!?! (I figure everyone on here knows that!) Did you know that you can add it to your chicken feed and it will improve your chickens mortality rate?!?! Check this site out! http://www.shadowridgedonkeys.com/perma_food_grade.htm The benefits of using DE are absolutely astounding! The best part is, it is a 100% natural product so it is completely safe to use!
