Black Widow Control in Southern Oregon (What Homeowners Should Know)
Black widows are present across Southern Oregon, especially in undisturbed areas such as crawlspaces, garages, storage corners, foundation vents, shop spaces, wood piles, and stored boxes. Because these spiders prefer protected environments, infestations often develop where clutter or long-term storage provides shelter.
According to the Oregon Department of Agriculture, black widows are the primary medically important spider of concern in Oregon, and bites should be treated seriously (ODA, 2016). In addition, research shows that female western black widows can lay roughly 300 eggs per egg sac and may produce multiple sacs over time (University of California Agriculture and Natural Resources, 2019). As a result, visible egg sacs can quickly lead to expanding populations.
