Hobo Spiders are very common in and around structures of Western Washington.
Cellar Spiders (also known as Daddy Long-Legs Spiders) can be large in size, but are completely harmless to humans.
Brown Recluse Spiders are not established in Western Washington, but they can be quite harmful if found.
Black Widow Spiders have only a small population in Western Washington, but can pose a significant health risk.
SPIDER CONTROL INFORMATION
Spiders come in many sizes and colors, but we all recognize one when we see one. They all have eight legs, and two body regions – cephalothorax and abdomen. They can be beneficial, as they consume 400 to 800 million tons of insects (and other spiders) each year.
Spiders can be very intimidating, but they rarely attack people; most spider bites are the result of a person’s accidental contact with a spider, or out of self-defense. Some spider bites can be very painful (even harmful), but spiders do not feed off of people, like mosquitoes, fleas, or bed bugs do. Most suspicious itchy/painful bumps are not the results of spider activity. While many species of spiders exist in Western Washington, only a few are very common or present a health risk to humans.
SPIDER CONTROL PROCESS
Spider control techniques can vary depending on the conditions around your property. Most spider services will include a brushing of the exterior of your building using a Webster brush on the end of an extension pole; this helps to stir up the population of spiders so they will be more exposed to the perimeter treatment that follows. We also remove as much of the established webbing and egg sac material as possible from the perimeter of the structure.
The perimeter application to the exterior of the building uses a residual insecticide, focusing on the foundation, underneath reachable eaves, around exterior lighting, around doors, and other harborage areas. Inside the structure, we can customize the control to fit your needs, with chemical or non-chemical techniques.
After the initial control has been established, we strongly recommend a recurring preventative service to keep the exterior populations from reestablishing at your house or building.
