Types of Spider Bites
Black Widow Spider Bite
- A shiny, jet-black spider with long legs (total size 1 inch).
- A red (or orange) hourglass-shaped marking on its under-side.
- Causes immediate local pain and swelling.
- Sometimes, you can see 2 fang marks at the bite site.
- Severe muscle cramps (especially stomach cramps) occur within 1 to 6 hours. These last 24 to 48 hours.
- Rarely causes death. (EXCEPTION: bitten by several spiders or small child is bitten)
- Note: Many are dry bites because the fangs are small.
- The brown widow spider is related to the black widow. It is found in southern US.
