Sac Spiders in Albuquerque NM

Referred to as the “yellow sac spider,” these arachnids in Albuquerque, NM, are frequently characterized by their pale yellow hue, sometimes exhibiting a subtle greenish tint. Like many spider species, sac spiders generally avoid human interaction and usually enter indoor spaces unintentionally. Their diet mainly consists of various spiders and other garden insects. Although infrequent, bites from sac spiders can cause discomfort to the victim.

Sac Spider Behaviors

Sac spiders are primarily nocturnal, engaging in hunting activities during the night. Unlike some spider species that use webs for trapping prey, sac spiders are hunters, directly catching their prey. In the fall, it is common to find these spiders indoors as they seek warmth during decreasing outdoor temperatures. When outdoors, sac spiders often reside in gardens and under vegetation in yards.

Dangers of Sac Spiders

While sac spider bites are infrequent, they can happen when the spider feels threatened. Unintentional threats, such as reaching into a box or a shoe, may lead to a defensive bite.
