Wolf spiders are aggressive when it comes to chasing down their prey, but not when it comes to humans. Even though they are large and hairy and look quite intimidating, wolf spiders actually pose little danger to humans and are more likely to retreat when they feel threatened.
Most of the time, wolf spiders are found running outside on the ground where they are likely to find prey. This includes under wood piles, rocks, leaves, decks, and the like.
Just as mosquito bites and bee stings don't cause severe reactions in most people, they can be toxic to those who allergic. The same can be said about bites from a wolf spider.
At the bite location, a victim may notice pain, swelling, or redness. For those who have allergic reactions, they may experience fever, pain, itching, or body aches. The skin may even turn blackish where the bite occurs.
If a wolf spider, or any other type of spider, bites you, it is important to get the appropriate medical treatment, especially if you generally have allergic reactions to insect bites. It is best to take the spider along for identification if possible.
The best way to avoid wolf spider bites is to control the spiders. A key part of control is eliminating what the spiders need to survive, particularly their food. Keep firewood piles and trash cans away from the house, as these things will attract pests, which in turn, attract spiders. Also clean up piles of outdoor debris that may harbor insects or spiders. Consider moving outdoor lighting away from the house or using yellow or sodium-vapor bulbs, which are much less attractive to many pests.
