Sow Bug Killer
This spider, Dysdera crocota, is also known as the pill bug spider or the sow bug spider. This spider is not a web-weaving spider, but hunts crustaceans such as pill bugs and sow bugs in the cracks and crevices of wood and rocks. The sow bug killer makes a habitat beneath debris and rocks on the ground and relies on powerful fangs to feed on its prey. Dysdera crocota is found in the southwest region of the United States but is also found in the northwest, along the eastern coast and on several other continents as well.
Funnel Weaver
Also known as the funnel-web spider, Tegenaria agrestis is the aggressive house spider or hobo spider, a member of the Agelenidae family. These spiders primarily build their webs in moist and dark areas such as basements. This spider creates a funnel-shaped web and waits in the bottom for prey to come in. The spider rushes out of the web to bite and subdue captured insects before drawing them deeper into the funnel.
Tarantula
Tarantulas are plentiful in New Mexico, and it is not unusual to see them traveling out in the open looking for prey or a new place to live. These spiders are large and covered in a fine hair. There are several species of tarantulas in New Mexico, and some are more aggressive than others. If disturbed, a tarantula can inflict a painful bite, although its venom is not deadly.
Black Widow
Commonly found in New Mexico, the black widow spider harbors a powerful toxin in its venom. Black widows are actually leading in spider-related deaths, and they create a bite that is both unpleasant and painful. Black widows cannot typically inject enough venom to kill a human, but five percent of those who receive bites do die from them. Get help immediately if you are bitten.
