Redwood City Spider Infestation — Identifying the Risk Level
The majority of spiders found in US homes are harmless. However, Black Widow and Brown Recluse spiders — both present across much of the US — deliver medically significant bites. Properties with high spider populations also indicate an underlying insect population sustaining them.
The harborage zones we treat most frequently in Redwood City are garages, basements, crawlspaces, and exterior perimeter areas with vegetation, wood piles, or debris close to the structure — conditions that support both spiders and the insects they feed on.
Recognising Black Widow and Brown Recluse Spiders
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.
How We Treat Spider Infestations in Redwood City
Before treatment begins, our Redwood City technician identifies every spider species present, assesses harborage zone distribution, and determines appropriate treatment intensity — with specific attention to whether venomous species are confirmed.
