Yellow sac spider

Yellow sac spiders are pale yellow to beige, with a slightly darker stripe running lengthwise on their abdomen. They are relatively small, about 1/4 to 3/8 inch long, with long legs. These spiders are most active at night.

Look for small, silken sacs or tubes in corners of ceilings, walls, or behind furniture – these are their daytime retreats. You may also notice itchy, raised welts from bites, although it's often difficult to confirm a spider bite. Increased spider activity at night can also be a sign.

MBPC offers targeted treatments to eliminate yellow sac spiders and prevent future infestations in your Grand Strand home. Our licensed technicians will identify harborage areas and apply appropriate pesticides, following SC Department of Pesticide Regulation guidelines. Regular pest control services are recommended to manage spider populations effectively.

Seal cracks and crevices in your foundation and around windows and doors to prevent entry. Reduce clutter in your home, especially in corners and storage areas. Regular cleaning and vacuuming can help remove spiders and their webs, especially in humid areas prone to spider activity along the coast.

Yellow sac spiders are commonly found indoors throughout Myrtle Beach, seeking shelter from the elements. They prefer dry, secluded areas such as closets, attics, and wall voids. In coastal SC, they can also be found under siding, in woodpiles, and among foliage near homes.
