One of the more common spider pests in the United States is the wolf spider, also in Las Vegas. These spiders garnered their nickname not because of their large, hairy, wolf like appearance, but because they were once thought to hunt in packs like wolves. Wolf spiders are excellent hunters. They do not build webs, but patiently wait in underground burrows for an unsuspecting cricket or cockroach.
Wolf spiders are brown in color, and can reach lengths of well over an inch. Their appearance is well known because of the Union Jack (British flag) impression on their backs. Although intimidating in appearance, wolf spiders don’t usually bite unless they are in danger or provoked. Wolf spiders are venomous.
Homeowners will frequently see these wolf spiders in their homes during the cooler months of the year. They enter homes looking for other insects to eat, and refuge from the elements. Even though the wolf spider’s venom is not lethal, their bites can cause health concerns.
