In this article, we will explore the top five largest and most dangerous spiders in New Mexico, providing information on their physical characteristics and potential risks.

Top 5 Largest Most Dangerous Spiders In New Mexico

Brown Widow Spider

The brown widow spider is one of the most dangerous spiders in New Mexico. Although it is considered one of the least dangerous species of widow spiders in the United States, its venom is still potent and can cause burning, swelling, and muscle spasms if a person is bitten.

Brown widow spiders can be identified by their black or dark brown color and orange or yellow hourglass marking on the underside of the abdomen. They build webs in secluded, protected sites such as under rocks, in woodpiles, and in other sheltered areas. Female brown widows are not aggressive and will usually withdraw to their retreats rather than attack when their web is disturbed.

Brown widow spiders are not native to the United States and are considered invasive. They are common in Florida and are becoming more common in the southern states of the U.S., especially Texas, and now appear to be spreading north through California.
