Somerville 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.
In Somerville, spider populations tend to be highest in undisturbed areas — garages, basements, crawlspaces, storage areas, and exterior perimeter zones with dense vegetation or debris.
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.
Treatment Methods Used in Somerville
Species identification and harborage mapping are completed before any product is applied. Treatment intensity and method selection in Somerville properties are determined by what species are confirmed present — not by a standard protocol applied to every job.
