Diatomaceous Earth by Animed
A natural flea and insect repellant for horses, pets and livestock. It also keeps moisture at bay in your horse stall, barn, garden or yard. It's a food additive used for livestock to better convert feed as it works to control worms and internal parasites without dangerous chemicals. The regular use of DE also can contribute to improved egg production by your hens. A dusting of DE around your barns or backyard compost piles will help keep moisture, odor and flies at bay. Please note that this is the granular form rather than the powdered form.
