Spider Control Seattle — When to Call a Professional
Most spiders in Seattle homes cause no harm and need no intervention. The exceptions — Black Widow and Brown Recluse — are present across much of the US and deliver bites that require prompt medical treatment. Beyond the venom risk, a high spider count in any property is a reliable indicator that an insect population is supporting them.
In Seattle, the highest spider activity consistently occurs in areas with low disturbance and available prey: garages, basements, crawlspaces, seldom-accessed storage, and exterior foundation zones with leaf litter or dense vegetation.
Black Widow & Brown Recluse Identification
Black Widow: shiny black body, red hourglass on underside of abdomen. Found in dark, undisturbed areas. Brown Recluse: light to medium brown, violin-shaped marking on cephalothorax. Found in boxes, closets, and basements. Do not attempt to handle either species without professional assistance.
