Do rattlesnakes live in Minnesota?
The majority of Minnesota snakes are harmless. Of the 17 snake species in the state, only two are venomous -- the Timber Rattlesnake and the Eastern Massasauga. Both are found only in the southeastern counties and are rarely encountered. It is, however, very uncommon for rattlesnakes to be found around human dwellings.
Brown recluse spider bite. The brown recluse spider, Loxosceles reclusa, is common outdoors and indoors in the southern and central United States. It is uncommon to extremely rare in the Upper Midwest. Only one specimen has been recorded in Minnesota (1953, Lake County).
- Wolf spiders are solitary creatures that roam alone in the night, stalking prey. According to Sewlal, they are “mostly nocturnal and often mistaken for tarantulas.” Wolf spiders often jump on their prey, hold it between their legs and roll over on their backs, trapping their prey with their limbs before biting it.
- According to the University of Minnesota Extension, only two brown recluse spiders have been found and recorded in Wisconsin over the past 25 years. Officials say while the spiders are not considered extremely dangerous, they do bite.
- The Long-Legged Sac Spider is a fast runner because it is an ambush predator. The silk shelters are not for ensnaring prey, but for resting. Its non-lethal venomous bite is painful humans and can be slow to heal. Its thorax is darker than its abdomen.

- Although the Northern Black Widow is slightly smaller and not "quite as venomous/dangerous" (definitely still not to be messed with), it is similar to the Southern Black Widow (L. mactans) in general behaviors. Please refer to L. mactans info page and the Latrodectus genus info page for more information.
- A few wasps can sting and paralyze, before eating the Black Widow. She is also a favorite food of the Praying Mantis. Some birds will eat these spiders but could end up with an upset stomach from her poisons. The bright red markings on her belly will warn possible predators that she is a nasty meal.
- Not all adult black widows exhibit the red hourglass on the ventrum underside or top of the abdomen — some may have a pair of red spots or have no marking at all. Female black widows often exhibit various red markings on the dorsal or top side of the abdomen, commonly two red spots.
