The big black-and-yellow spider in the large wheel-shaped web with a zigzag of white silk down the middle. Alarming to look at, beneficial, and not a house pest.

How to Identify It
Large black abdomen with bold yellow markings, black legs banded with yellow or red, and a classic orb web up to two feet across with a dense zigzag (stabilimentum) in the center. Usually hangs head-down in the middle.
Size: Females 19–28 mm body
Commonly Confused With
Banded garden spider (Argiope trifasciata, silver with thin stripes) and barn spiders. None are dangerous.
Why It Shows Up
They don't come inside. Webs are built in sunny gardens, between shrubs, on porch railings, and across walkways where flying insects travel.
Where Homeowners Find It
Flower beds, tomato cages, shrubs, fences, and between deck posts from midsummer on. Egg sacs are brown, papery, and pear-shaped.
Seasonal Activity in KC
Adults July through the first hard frost; egg sacs overwinter and spiderlings disperse in spring.
Risk Level
None. A bite would require handling and is comparable to a bee sting. They eat grasshoppers, wasps, and mosquitoes.
What You Can Do Yourself
- • Relocate the web with a stick if it blocks a doorway; the spider rebuilds overnight.
- • Leave egg sacs alone if you can — next year's mosquito control.
Our Take
No treatment. If we spray a garden spider on a service visit, we are doing it wrong.
