Likely brown recluse spider (juvenile)

Dark, dry, undisturbed areas such as closets, boxes, basements, sheds, and wall voids; native mainly to the south-central and Midwestern United States.

A nocturnal predator that captures insects and other small arthropods, often scavenging prey caught in its irregular web.

Shy and nonaggressive, it retreats when disturbed and is most active at night. It may wander indoors, especially during seasonal temperature changes; identification from this blurry image is uncertain.

Its bite is uncommon but can cause localized tissue damage and, rarely, systemic illness; seek medical care for concerning symptoms. It benefits ecosystems by consuming household pests.
