I normally spray my yard perimeter and house perimeter with a product called Eco Smart that is made only of oils of rosemary, clove, thyme and some citrus oil. It works wonders to keep the scorpions, black widows, stinging centepedes and other creepy crawlers out of my home and it smells awesome. I don't use anything with chemicals around my home because of my dogs. Just wondering if this would be safe to use around the chicken yard and coop? I will not spray INSIDE, but just the outside perimeter. I'm reading that some essential oils are BAD for the chickens. I plan to use food grade DE inside their area.
