I've had my coop for three years now. It's a 10x16 thing up on skids with wood decking floor. The floor is about a foot off the ground and we put a stone underpinning all around it to make it look nice, like it has a stone foundation. This set up is apparently crazy attractive to brown recluse spiders. In three days I caught 10 on a sticky trap. My guess is that they are living under the floor and mass producing. I'm honestly considering getting out of my favorite hobby ever. Im tired of being fearful and having nightmares. What can I do?? We only use organic/natural practices. Insecticides don't work against recluses anyway.
