About the brown recluse

Brown recluses are reclusive nocturnal hunters that bite humans only when accidentally pressed against skin — putting on a shoe they crawled into, slipping into bedding, reaching into a stored box. Their venom is necrotic, which means a bite can develop into an open ulcer requiring medical treatment. They have a distinctive dark violin shape on the back of the body and six eyes arranged in pairs (most spiders have eight). Always shake out shoes and clothes from storage, and declutter.
