I might suggest that you sign up for a subscription to First Saturday Lime. It’s a product I have been using for probably close to 10 years and there are no bugs on my chickens or in my coop. Every time I clean my coop, I’ll take their a bag and sprinkle it all over the floor and throw a whole bunch in nest boxes. In between cleaning the coop, I’ll throw a couple handfuls of First Saturday Line in the nest boxes. The stuff really works. I might also mention that I have asthma, and First Saturday Lime does not bother my breathing at all.
