The Brown Recluse Spider In New Mexico

This species is only found in the eastern region of New Mexico near the Pecos River Valley and the Texas border. The brown recluse has a rather undeserved reputation for being more dangerous than it is! This is often mistaken for another spider, its cousin, the desert recluse. While the brown recluse has a painful bite and necrotic venom as well, the bite is far less serious and often doesn’t require medical care.

1. Brown Widow Spider

The Brown Widow In New Mexico

Brown widow spiders are common throughout the state of New Mexico. As one of 32 species commonly referred to as widow spiders, it has a fearsome reputation! However, this is largely undeserved. The brown widow is far less venomous, and its bite lacks the ability to cause lasting harm or death. This species is not originally native to the United States and is believed to be indigenous to Africa. Due to its high likelihood of choosing areas close to humans, it was most probably shipped in by accident!

Summary:

Fortunately, none of the Five Largest Spiders in New Mexico has a bite lethal to humans. In fact two are not even venomous! Nonetheless, a bite from one of these spiders can be painful. It is also fortunate that these spiders/tarantulas are all reclusive or docile. Also, they all prefer the climate and terrain found in New Mexico and the southwest of the United States.
