Quick answer
Wild brown recluse spiders typically live around 3 years, though predation, disease, and habitat quality shift the average.
Lifespan in the wild
Most brown recluse spiders reach roughly 3 years under natural conditions. 2–4 years; slow-growing and long-lived for a spider
Factors affecting longevity
Predators, disease, food scarcity, and human pressures all shape survival. Males and females may differ in average lifespan.
In captivity or as pets
With veterinary care and steady nutrition, brown recluse spiders sometimes live longer than wild averages — though wild longevity reflects natural ecology.
Oldest recorded individuals
Long-lived brown recluse spiders are rare in the wild; research and zoo records help set upper limits for the species.
