Spider identification

Barn funnel weaver in Ontario

The big brown long legged spider sitting in a flat web in the corner of the basement, the window well or the garage is the barn funnel weaver. It is the spider people photograph and ask about, wanting to know whether it is a hobo spider. It is not; the hobo spider does not occur in Ontario, and this one is harmless.

How to recognize it

Brown with a striped head, a mottled or chevroned abdomen and long banded legs, about 1 cm in the body and up to 4 cm across the legs. The web is the tell: a flat sheet of silk in a corner or along a wall with a funnel at one end leading into a crack, where the spider waits. It runs out across the sheet when something lands and back into the funnel when disturbed. It is very fast but does not jump and does not wander far.

Where it lives on your house

Basement corners, window wells, behind the furnace and water heater, under stairs, in garages, sheds, crawl spaces and the bottom of exterior walls under the siding. It likes undisturbed corners near the floor and can occupy the same web for years.

Scientific name
Tegenaria domestica
Also called
domestic house spider, giant house spider (in error), hobo spider (in error)
Bite
Not a concern.

When you see it

Year round indoors, with males wandering in late summer and fall looking for females, which is when they are found in bathtubs and on floors. Outdoors it is active from spring to fall at the base of walls.

Does it bite?

Not a concern. It retreats into the funnel at the first disturbance, and a bite would need the spider to be trapped against skin. The hobo spider reputation it gets blamed for has been dropped by health agencies even where that spider lives. Most "spider bites" in Ontario are never confirmed; see the bite section of our guide to common spiders in Ontario for what a real one looks like.

What Spider Pros does about it

Indoors, vacuuming the web, the funnel and the spider is the fix, and we quote indoor work separately for existing customers. Outdoors it builds the same funnel web in window wells, the gap under the bottom course of siding and the foundation line, and those are areas we clear and, where they keep refilling, treat on every visit. Keeping window wells clear of leaves and sealing the gap under the siding removes most of its habitat. Every visit ends with a written summary of what we found and where product was applied, if any. Our spider control service and 60 day guarantee pages have the details and pricing.

Often confused with

Grass spider, Wolf spider, Dark fishing spider. The grass spider is its outdoor relative with the same funnel web but on the lawn and in the foundation plantings. Wolf spiders are hairier and stouter, build no web and wander the floor. The dark fishing spider is much larger and found on docks and boathouses. The full list with photos is in the common spiders in Ontario guide.

Good to know

Questions people ask

Is this a hobo spider?

No. The hobo spider does not live in Ontario. The big brown spider in a funnel web in the basement is the barn funnel weaver, which is harmless.

Is it a giant house spider?

Not the one from the news stories, which is a European relative found in the Pacific Northwest. The barn funnel weaver is the same family and the same shape, and equally harmless.

Why does the web in my window well come back every year?

Window wells are ideal habitat: dry, undisturbed and full of insects. Clear them of leaves and debris each spring and fall. We clear and treat them on our visits.
