Purchased a 7X7 Rubbermaid shed to go over/around the tank to my well. When I opened the box there were several brown recluse spiders in it. I just finished putting the shed together and took a shower about an hour ago. I noticed a burning itch in my armpit. I’m not sure if a spider bit me or what but it’s the worst burning itch I’ve ever had. Does anyone know what a brown recluse spider bit look like?
