Wolf Spiders
HarmlessWhat it is
A robust hunting spider that does not rely on a capture web. Wolf spiders usually live at ground level, are fast-moving, and may enter buildings accidentally; they are generally not dangerous to people.
How to recognize it
Large, hairy brown spiders that run fast on the ground at night. Females carry egg sacs or young on their backs.
Where you will find it
Ground-level areas: lawns, garages, basements, and doorways.
Why it matters
They wander indoors by accident and are generally not dangerous, though a bite can hurt.
What to do
- Do not handle spiders or reach into stored items with bare hands. Wear gloves when moving boxes, wood, or equipment in garages and sheds.
- Reduce clutter and vacuum webs and egg sacs from corners and storage areas.
- Note where you see them and take a photo if you can do so safely.
- Contact a licensed pest professional if you are unsure what kind it is or you see many.
When to call a professional
- You see many spiders or repeated sightings of the same kind.
- You think it could be a black widow or another medically important spider.
- Someone was bitten (seek medical care for a bite with spreading redness, pain, or illness).
