in the coop? It's fab for bugs, parasites etc. I use a mix of dish soap, TTO, another essential oil (sweet orange, grapefruit, lavendar etc), a bit of borax (fab for mold, fungus etc) and hot water when I clean my house. It's easy, inexpensive and leaves everything disenfected and smelling great. So, today I cleaned the gross chick house I'm borrowing. It was given to a friend and they dropped it at my house....free delivery. The coop was so nasty I couldn't stand 5 feet from it. So, I took the hoe and scraped it out, used a grout brush and a broom. Then a mild bleach solution to wash followed by a TTO/Grapefruit wash. The coop actually smells Good! My 13 y/o DD said she couldn't believe she could see the floor and that it didn't stink...a high compliment.
