UMaine Cooperative Extension: 'black widows and brown recluse spiders are not native to Maine and are not known to survive our winter temperatures,' and 'there are no Maine-native spiders whatsoever that are considered particularly dangerous to humans.' The northern black widow is listed only as a possible infrequent inhabitant as far north as central Maine.
