I really like it...Useful for anything just about. Got all the mites off my rosebush, and killed the ants climbing to my hummingbird feeder...Sprinkle under shavings in coop and nests, and around ground. Used in 6 mo. old pups food for deworming. Use food grade DE only, and can use for a BUNCH of things. You can even take it in water or juice to cleanse out parasites. Used it to dust chickens each month. Only one time did I find any mites on one of my chickens and they were from an outside perch under the leanto that she sat on a lot...Put DE on the bird and the perch and within a week and a couple of treatments no more mites.
