Commonly Asked Questions How worried should I be about cellar spiders?Ĭellar spiders can live for about two years and produce up to 60 offspring.

Each generation may yield 13 to 60 offspring at a time. Females produce as many as three egg sacs over the course of their lifetime. Life Cycleįrom egg to adult, immature cellar spiders take about one year to fully develop. They target insects, other spiders, and small invertebrates, particularly ants. Like most spiders, cellar spiders are beneficial creatures that prey on other pest species. The long-legged spiders also prefer higher levels of humidity.
