When spiders are busiest around Livingston
Western black widows are present throughout Montana and shelter in woodpiles, burrowing sites and low-traffic areas around homes; MSU Extension emphasizes habitat modification near entrances (MSU Urban IPM).
MSU Extension Urban IPM: 'The brown recluse is not native to Montana' and no specimen has ever been positively identified in the state by a trained arachnologist or entomologist; 'it is extremely unlikely that any diagnosed spider bite from this area is from a brown recluse.' A recluse could only arrive as a hitchhiker in shipments or boxes.
