Scientists say the majority of the spiders are 10-year-old males looking to mate with females hidden in Colorado's grasslands.

Officials say tarantulas are mostly harmless to humans, but have bites that can cause injury or allergic reaction and hairs that can be irritating to the eyes, mouth and nose.
