Brown recluse spider (suspected source of lesion)

Dark, undisturbed areas such as woodpiles, sheds, basements, closets, and under furniture.

Insects like crickets, cockroaches, and silverfish.

Nocturnal and non-aggressive hunters that only bite humans defensively when pressed against skin (e.g., inside clothing or bedding).

Risks: Venom contains sphingomyelinase D, which can cause necrotic skin lesions (loxoscelism), systemic symptoms, or secondary infection. Benefits: Provide natural pest control by eating common household insects. Note: This image shows a significant lesion and you should seek medical attention immediately. Do not attempt to self-diagnose skin wounds.
