During this period, males tend to wander long distances in search of females. Eggs are laid into a spherical silken sack spun by the female, usually in September or October. The sac is then placed within or adjacent to the funnel, usually on the underside of a rock or other object. The sac is then covered with a thin layer of soil, wood chips, or other debris, including prey. The debris-coated sac is then often covered with another layer of silk.
Eggs hatch the following spring.
Most Tegenaria molt about ten times over a span of two years before reaching sexual maturity. Immatures are commonly found wandering in the spring searching for webs. They are also excellent indicators of carpenter ant infestations as their webs are commonly near the house where ants forage, and become trapped. While elimination of some spiders is acceptable when they are an annoyance, wholesale elimination is ecologically unsound and results in more nuisance pests. Cultural The best method of control for Tegenaria is that of prevention.
