Spiders found in Puget Sound and throughout Washington State.
There are various species of spiders found throughout Washington and the Puget Sound region. While spiders in general can be beneficial in the sense of eliminating other various pests such as mites and other insects, their bites should be avoided. How the venom from a spider bite affects an individual will largely depend on multiple factors such as age of the victim, general health and sensitivity.
This web page covers some general information on one of the most common spiders found here in the Northwest: the hobo spider. In addition, information on the black widow spider as well as the brown recluse is provided for better identification of this more toxic species.
The hobo spider (Tegenaria agrestis)
The hobo spider, or also known as the “aggressive house spider” is among the most common house spiders found here in western Washington. They like to build funnel webs in moist, dark areas to ensnare their prey, and can often be found in a home’s window wells and basements. Hobo spiders can be identified by their long, hairy legs, dark brown color and unique yellow pattern located on its abdomen. They can appear somewhat large in size (7/16 – 10/16 body length inches), and are known to be swift runners, but poor wall climbers.
The bite from a hobo spider has been described as a slight prickling sensation, followed by an insensitive, small hard area that reveals itself within 30 min, surrounded by a reddened area 2″- 6″ in diameter.
The black widow spider (Latrodoctus hesperus).
The black widow spider, which is more common to eastern Washington, can be easily identified by its dark black bulbous body and red hourglass marking located beneath its abdomen. The immature and males are smaller in size than mature females, and will in general have white, yellow, and red spots/bands over the back.
Typically found in dark outdoor places such as sheds, privies, garages, beneath homes and littered areas, the shy black widow spins amorphous webs. Its venom is a nerve toxin, and has been described as a burning sensation that can last for a few minutes after the initial pinprick of the bite. The pain typically then progresses through the bitten limb and localizes to a certain degree in the back and abdomen, causing the muscles to stiffen and become rigid. This is usually accompanied by abdominal cramping along with other symptoms that may include tremors, nausea, speech defects, insomnia, depression, and a rise in temperature. These symptoms may manifest within minutes or hours of the bite, and while it can be painful, it is not often fatal.
The brown recluse (Loxosceles reclusa).
The brown recluse, or otherwise known as the violin or fiddleback spider, spins irregular webs and prefers to hide in crevices, cracks and beneath furniture. They can be identified by their long legs, their color, which varies from a light fawn to a darker chocolate brown, but mostly by the distinguishing dark brown fiddle shape located on its back. Overall, they are somewhat smaller than the black widow, and while the females are slightly larger than the males, both sexes deliver a venomous bite.
Since the brown recluse spider has not yet established itself in the Pacific Northwest, its bite is often times confused with that of the more common hobo spider which produces similar skin injuries/lesions. The typical reaction followed by a bite is delayed tissue death. For more information on the brown recluse, please visit: https://en.wikipedia.org/wiki/Brown_recluse_spider
Tips on how to avoid spider bites and make your home pest free.
There are many things that you can do to prevent spiders from taking over your home or business, and ways to go about it that well help protect you better from getting bitten:
- Eliminate small cracks and openings to your house with the use of sealants (ie. Caulk) and snug fitting screens and doors.
- Get rid of clutter (boxes, furniture, etc) and keep a clean living environment in and around your house.
- Wear pants, a long-sleeved shirt and protective gloves when removing webs around the inside and outside of your home, or when moving stored wood, boxes, etc.
- If there is a spider on you, be sure to brush it away. Crushing it increases the risk of a bite!
