The northern and southern parts of Wisconsin have many spider species of which the northern widow and brown recluse are considered poisonous. The northern yellow sac could also hurt humans, though they are considered as mildly venomous. However, the deadly species do not dwell here in abundance, with the northern black widow being present in just 10 counties. The brown recluse thriving here is also present in minimum numbers.
