Although all spiders are venomous, most venoms do not pose a threat to humans. Moreover, spiders tend to avoid people and bite only when cornered. Despite human avoidance, the spiders most likely to bite, venom, or otherwise be of concern include:
- Northern Widow
- Yellow Sac Spider
- Black & Yellow Garden Spider
- Wolf Spider
- Jumping Spider
- Nursery Web Spider
- Woodlouse Hunter

Despite the daunting list of symptoms, death rarely results from their bite and is typically associated with other conditions. It is essential to keep in mind that the other cobweb spiders mentioned above do not have a venom that is considered dangerous to humans.
Signs inside home
Their webs are irregular in formation and small to medium in size. They are most likely to occupy small enclosures, especially in and around.
- Outbuildings
- Sheds
- Pump enclosures
- Meter enclosures
- Rodent bait stations
- Building perimeters along the foundation
2. THE YELLOW SAC SPIDER
Yellow sac spiders (Cheiracanthium mildei) are more common throughout Minnesota. This spider belongs to the Eutichuridae family and the long-legged sac spider, which is also found in Minnesota.
Bite appearance
Bite reactions vary from person to person and may include:
- Bruising for a short time
- The color red
- The feeling of being sore
- The necrotic wound of small size
- Venom spreads quickly
- Despite mild reactions, venom is not considered dangerous to humans. Regardless of the poison, the primary concern is the possibility of secondary bacterial infections from the bite.
What is its location?
Yellow sac spiders are found throughout Minnesota and can be found indoors throughout the year. They may rest on walls or ceilings, but they usually hide in silken retreats:
- Stones underfoot
- Under the bark
- The following leaves
- Building corners
- Indoor recesses are dark
- Folds in the fabric
Signs they are inside the house.
The spider itself is not uncommon as the first sign, but their tell-tale sign is their sleep sack. They spin a small tube or sac around dawn to sleep in. Despite thickly spun sacs, they don’t spin other webs. You may find these sacs in rolled-up leaves or underneath logs, but they are just as likely to be in a corner.

- Weavers of marbled orbs
- Weavers of Shamrock Orbs
- Weavers of Hentz orbs
- Spiders with cat faces

In Minnesota, where can they be found?
Outdoor spiders are most likely to build their homes in:
- Gardening
- Plants
- Branches of trees
- Plants that grow weeds
- Human-made structures between each other
- They are usually found head down in the center of a sizeable orb-shaped web.
4. THE WOLF SPIDER
Unlike garden spiders that build webs, the Wolf spider of the Lycosidae family is abundant in Minnesota and is an avid hunter. While it is aggressive toward its prey, it has no interest in human beings wandering around – not even the tiniest tots.
Venom & Bite
The bite may be as painful as a pinprick or as painful as a bee sting, but the venom is not harmful to humans. However, secondary bacterial infections from bites are possible.
What is their location?
Under stones and debris, wolf spiders thrive in every corner of Minnesota, but they tend to move indoors as the temperature drops.
Signs of their presence in a house
Wolf spiders are active hunters, so the first sign they are in your house is usually the spider itself.
5. THE JUMPING SPIDER
Jumping Spiders (family Salticidae) is a colorful variety of spiders in Minnesota. Besides color, the movement of the:
- Bold Jumper
- A Zebra jumper is likely to catch your eye.
Venom & Bite

What is their location?
Jumping spiders typically lurch around exterior walls, window screens, tree trunks, logs, rocks, etc.
Signs they are inside the house.
As they often hitchhike into homes on clothing and pets, you may not know that they are present until they come out in short, sharp bursts. Hopping is more common than running or crawling – hence their name.
6. NURSERY WEB SPIDER
In Minnesota, the Pisauriadea family includes the following spiders:
- Spiders in the forest nursery
- Fishing Spider with Stripes
- Fishing spider in the dark
With an impressive leg span, they can jolt even the calmest of nerves when they appear.

7. THE WOODLOUSE HUNTER SPIDER
Woodlouse Hunters of the Dysderidae family have an aggressive appearance, including some threatening fangs.
Venom & Bite
They may bite with their distinctive fangs, but their venom is not dangerous. Secondary bacterial infections from their bites are possible, however.

These spiders hunt at dusk in rural and residential areas such as:
- Subterranean spaces
