Mites do not give AF about DE...

7 days into removing chickens from the coop, deep cleaning, caulking, painting, drenching coop in Elector PSP, and a thick dusting of DE, mites are back and do not give a flying F about the Diatomaceous Earth. They just happily march right through it and build nests in it like it's a nice comfy winter wonderland.

​

All the gray you see in this picture is DE. At least, all the gray that isn't moving. 3 days of them marching around in this stuff and they could not care less.

​

Just a heads up, since I've seen a lot of comments in this sub recently telling people they just need to throw DE everywhere to solve their mite problems. It does basically nothing.

​

Getting a prescription for Exzolt next. Wish me luck.
