Technically, all spiders have poison. That’s how they’re able to kill the insects they eat. Only a few have poison strong enough to hurt people.These include:
- Brown recluse spider
These spiders are yellow-orange to brown with a violin-shaped marking on the body. Brown recluse spiders hide in closets, over door frames, in basements and in corners.
- Black widow spider
These have a shiny black body with a red hourglass on the underside. Black widow spiders prefer dark, quiet places like garages, meter boxes or furniture.
- Hobo spider
Hobo spiders are medium-sized and brown. Their abdomens have markings on them. Hobo spiders are not usually found in Kansas or Missouri. Their bite can cause skin reactions.
- Yellow sac spider
These pale spiders are greenish, tan or light brown. Their front legs are longer than the other three pairs. Instead of webs, yellow sac spiders build sac-like tubes in leaves, under logs, in shrubs or in the junction of walls and ceilings. Their bite is painful and can cause skin reactions.

Reactions to spider bites vary widely, depending on the type of spider, the amount of venom released and the person who was bitten. Reactions can include:
