Barn funnel weavers are small house spiders, females 7.5-11.5 mm and males 6-9 mm long, with dark orange-brown bodies, striped legs and two faint black stripes on the cephalothorax. They live worldwide in homes, barns and sheds, building large, undisturbed funnel webs that can persist for years.

Is it a pest in the house?

Their webs can become large if left undisturbed, and indoor females may live one to two years on the same web. They are common in U.S. sheds, barns, door crevices, under rocks and boards throughout the year.

Does it bite or sting?

Barn funnel weavers rarely bite; when they do, it is in self-defense and usually does not break the skin. Penn State knows of no documented bites from barn funnel weavers and expects any bite to be no worse than a grass spider's.

How to get rid of it

To capture one, place a container in front of the spider and gently push it from behind so it walks into the opening. Spiders instinctively move forward when disturbed from behind, making this method effective.

Where it lives

In Europe they occur from Scandinavia down to Greece and the Mediterranean, and they are listed in Denmark’s spider checklist. In North America they are found from maritime Canada to the southern United States.

What it eats

They are active hunters that rely on vision, speed and their webs to capture prey. They respond to light, moving toward or away from it depending on the situation.

Life cycle

Spiderlings hatch from egg sacs and reach maturity within a year. Females usually survive the winter in sheltered spots and can produce multiple egg sacs.

Lookalikes

They were once thought to be close relatives of the Giant House Spider, now placed in the genus Eratigena. Like grass spiders, they are extremely fast and shy.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
