Like black widows, the female S. grossa is 6-10.5 mm in length, and dark colored, with a round, bulbous abdomen. Typical coloration ranges from purplish-brown to black, with light-colored markings. Unlike black widows, redbacks, and other Latrodectus species, S. grossa does not have a bright red hourglass pattern or any other bright markings. Like many spiders, the male is sometimes smaller; But can many times be nearly as long as the females.

The bite of S. grossa is known to be medically significant in humans, but minor, without any long-lasting effects. Symptoms of bites include blistering at the site of the bite, and/or a general malaise lasting for several days.

Amco’s Commercial Wildlife Control Department specializes in the control and prevention of wildlife pests for commercial properties. Our wildlife technicians provide customized solutions that are effective, humane and long term.

Wildlife Exclusion and Prevention Is Key

Here at Amco, our Wildlife solutions focus heavily on prevention of unwanted wildlife after exclusion is complete. Without proper prevention, wildlife pests are likely to re-enter a structure causing the property owner to find themselves with the same problem. Our goal is to eliminate and prevent the problem from happening again.
