How to recognize a black widow
Females are shiny black, about half an inch long, and have a red hourglass shape on the underside of the abdomen. Males are smaller and tan. Their webs look messy and irregular, and they are strong.
Where they hide around homes
- Garage and shed corners
- Woodpiles, stacked lumber and rock piles
- Meter boxes, irrigation boxes and block wall gaps
- Under patio furniture, planters and play equipment
- Window wells and dark, undisturbed spaces
How serious is a bite?
Only female black widows have venom that can affect people. A bite can cause pain, nausea, sweating, swelling and goosebumps. Serious problems are rare but are more of a concern for young children, older adults and people with health conditions. Get medical advice after a suspected bite, and call Poison Control at 1-800-222-1222. Try to capture the spider for identification.
How to stay safe
- Wear gloves when you handle firewood, boxes, hay or debris.
- Shake out outdoor gloves, shoes and towels.
- Clear webs from around play areas and entryways.
- Keep woodpiles and stacked items away from the house.
- Seal gaps and reduce clutter in garages and sheds.
