Rumors about Its Bite

Stories of being bitten by Brown Recluse Spiders are greatly exaggerated, perhaps due to incorrect identification. While populations of Brown Recluse Spiders are rare, there are other species of recluse spiders.

When one bites, it is in self-defense. Interestingly, the majority of bite cases involve rolling on the spider while you sleep (38%) or while you are getting dressed (32%), usually in clothes that had been hanging for a long time.
