Brown Recluse Spider
Brown recluse spiders are highly toxic. All it takes is one bite and their venom will start to eat away cell membranes, skin, fat, and blood vessels. This will lead to necrosis, which is the process where infected tissue starts to die. It’s why the brown recluse spider is considered one of the six most poisonous spiders in the United States alone. Besides necrotic tissue, other symptoms of a bite include chills, fever, nausea and joint pain.
