Araneidae; tetragnthidae

Orb weavers are small to large spiders. Generally they have a large, bulbs abdomen and make classic orb-shaped webs.

Orb weaving spiders are often found around buildings and homes in late summer and early fall, especially around overhanging structures such as porches or entryways, or in ornamental plants.

These spiders die out every year and leave an egg sac behind which hatch in the spring and spiderlings disperse. Orb weavers are common near exterior lighting.

How To Keep Spiders Away
Pest control experts
  • Change exterior lighting to sodium vapor or yellow bulbs. These spiders like to build their webs where there are lots of flying insects.
  • Minimize their harborage around the property.
  • Seal exterior cracks and crevices to reduce hiding places.
  • Install tight-fitting door sweeps and window screens.
  • Regularly vacuum individuals and webs.
When They Enter A Building
Pest control experts

Orb weavers do not commonly enter homes but instead build their webs on the outside of homes and structures especially where large numbers of flying insects can be captured.

  • Step on, or smash individual spiders that enter buildings.
  • Vacuum them up.
  • Catch and release (with a glass jar) spiders found indoors.
