Spider Removal

Even after living in the Northwest for decades, you may see a spider and think to yourself, “I’ve never seen that before.” According to the Oregon Department of Agriculture there may be as many as 500 species of spiders found in the Northwest. With the warmer weather comes an increase in stinging insects as well as other flying insects.

These are a great food source for spiders, as are crawling insects. These favorable conditions cause spider hatch-lings to leave their egg sacs, and you will likely see many more around.
Spiders typically hatch in the winter and fall, but stay in their egg sacs until spring. Keeping your eyes peeled for spiders is only useful if you know what to look for. Below are some of the most common poisonous spiders in the Northwest, and how to identify them. If you believe you are in the presence of a poisonous spider, call a professional exterminator for immediate spider removal in Portland.

Poisonous Spiders in the Northwest

Hobo Spider

  • Though their bites are not fatal, and scientific studies have shed new light on whether or not hobo spider bites cause necrosis, they should be avoided. This species is often found in fields. There are some traits to look for when identifying one. Since positive identification only comes with a microscope, a cautious approach is always better. Look for:
  • Size: 1.75 – 5cm
  • No bands on the leg joints
  • A distinct V pattern on the abdomen
  • A light stripe down the center of the sternum

Brown Recluse

  • These tiny spiders have wide habitats that span from woodpiles and sheds, to closets, garages, and cellars. If it’s dry and quiet, a brown recluse will like it. Though brown recluses typically bite when pressed against the skin, their hemotoxic venom can cause dermonecrotic lesions. If you see one, call us for spider removal in Portland. Look for:
  • Size: 6 – 20mm
  • Three pairs of two eyes each
  • Slightly lighter leg joints
  • Short hairs on the abdomen

Black Widow

  • These spiders are often found under stones, in sheds, garages, and woodpiles. They like cluttered areas that don’t see much traffic. Black widows are very venomous, and a bite can be fatal for those with heart problems, the elderly, or children. With distinct markers they are fairly easy to identify, so seek professional spider removal in Portland to avoid danger. Look for:
  • Size: 1.25cm long
  • Shiny black body
  • Red hourglass-shaped marker beneath female abodmen
  • Marker may be a dot, or the color may be orange
