MRSA and Spider Bites: No Link—Debunking the Myth

MRSA spreads through human-to-human contact or contaminated surfaces—not spider bites. Spiders inject venom, not bacteria, and no scientific evidence links spider bites to antibiotic-resistant bacterial transmission.

If a Bite Looks Infected

Redness, swelling, warmth, or pus suggests secondary infection from skin flora or environmental microbes—not the spider itself.

Care Steps

• Wash the area.
• Apply antiseptic.
• Cover with clean dressing.
• Seek medical attention if symptoms worsen.
