Have never seen any bugs on my chickens or in the coops. Dusting with DE since day one. I keep very clean runs and coops with sand in the runs and under roost bars and scoop every day. We have had a lot of rain lately and the sand in runs is now packed down. When I go to clean up the poop is packed down and LOADED with white mites! Round bodies so I am sure it is mites. I want to super dust with 5% Sevin but we are due to have another week of rain and storms. Not raining now but will be later today. Do I need to wait until the rain is over for a few days? Creepy creepy creepy! Thanks!
