Brown recluse spider egg sac (discarded remnant)

Dark, undisturbed indoor locations like closets, attics, and crawlspaces, or under debris outdoors.

While the egg sac is non-living, the emerged spiders hunt soft-bodied insects like crickets, cockroaches, and moths.

Females produce one to five egg sacs per year; sacs are off-white to beige with a loose, silken appearance. The remnant pictured appears to be a hatched or damaged silk casing.

The presence of an egg sac indicates a potential infestation. Loxosceles reclusa possesses necrotic venom that can cause significant skin lesions in humans if bitten.
