Funnel Web Spiders

General Description
Though they occasionally wander into structures, funnel web spiders are typically found around the foundation of homes, in grasses and bushes. They remain hidden deep inside funnel-shaped webs that are quite noticeable on dewy mornings. Unlike many other web-building spiders, funnel web spiders are fast runners. When an insect or another spider comes near, the funnel web spider dashes out to subdue its prey. This group includes medium-sized species such as the grass spiders (Agelenopsis spp.), usually found outdoors, and house spiders (Tegenaria spp.) which often occur indoors. grass spiders are often brown with dark stripes on their backs. This and their “creepy” appearance may be why they are sometimes mistaken for brown recluse spiders.

General Control
Funnel web spiders are prone to enter structures in the fall. To help prevent this, check the foundation for cracks and holes. Also check vents, around window and door frames, and for gaps around utility and cable lines. Seal these potential entry points with caulk, expandable foam, concrete or similar materials. Inspect around a structure’s foundation for the presence of the spiders and their webs. Applications of residual pesticides, such as wettable powders or encapsulates, around foundations in late summer or early fall can help prevent these spiders from entering as temperatures fall.
