Crab Spider Facts

  • Female crab spiders can be white, yellow or pale green and are much larger than their darker patterned, longer legged male counterparts.
  • Crab spiders prefer gardens, grassy areas and urban parks rather than indoor environments.
  • Crab spider bites leave two puncture wounds caused by the hollow fangs used to inject venom into their prey.

How to Get Rid of Crab Spiders

Indoors, treating crab spiders can be a tricky affair, as most commercial sprays don’t contain residual materials to deter future crab spiders from entering greenhouses. When you suspect crab spiders are turning your greenhouse experience into an unpleasant horticultural environment, contact Truly Nolen to inspect your greenhouse and determine the culprit of your workplace or leisure time discomfort.

In your garden, encourage songbirds to visit your yard, as they like crab spiders for dinner. Unless you are dealing with an extreme infestation, which is unlikely, crab spiders are harmless to humans and actually help control mosquitoes, flies and other pests in your backyard.

But if you really feel the need to eradicate crab spiders from your patio, porch or pergola, you can consider:

  • From time to time, remove crab spider nests with water from your garden hose or a broom. Remove plant debris, such as piles of kindling, grass clippings and mulch.
  • Keep grass near your outdoor entertainment area cut short.
  • Plant non-pollen-producing plants such as yarrow, dianthus, echinacea, hypericum, Russian sage, daylilies, cone flowers, veronica, salvia, hosta, roses, viburnum, hibiscus, rose of Sharon, coleus, caladiums and hydrangea.
