Wyoming is home to several species of poisonous spiders, including the black widow and the hobo spider. These spiders can be found throughout the state, particularly in dark, secluded areas such as basements, attics, and woodpiles. While encounters with poisonous spiders are rare in Wyoming, it is still important to be cautious and take preventive measures to avoid being bitten.

How do poisonous spiders in Wyoming hunt for prey?
Poisonous spiders in Wyoming, such as black widow spiders, typically rely on their webs to hunt for prey. They will spin intricate webs in dark, sheltered areas like under rocks or in crevices.

Some spiders, like wolf spiders, are active hunters and will actively pursue and capture prey.
