Are Brown Recluse Spiders Moving To The North?

Recently a man freaked out after finding a brown recluse spider in his garage. Most people may not have been so alarmed to find a spider in their garage, but brown recluse spiders were not thought to inhabit the state of Michigan, so seeing one in his Michigan garage took him by surprise. Researchers are beginning to wonder why the brown recluse is moving farther north than usual, and is the venomous spider moving to the north for good?

Based on what is already known about the brown recluse, it seems unlikely that the spider just made a permanent move to the north. According to the guy who wrote the book on brown recluse spiders, spiders like the brown recluse do not disperse easily. These spiders are not big movers. Once they find an environment that meets their needs they are not likely to abandon that environment. If you find a brown recluse in your garage, and your house is twenty feet away, you are still not likely to ever find them in your house because the environment in the garage is all they needed for several months during the winter. One women in Kansas spent a period of eleven years trapping brown recluse spiders that she had found in her home. Over the years she collected over two thousand brown recluse spiders, and during that time, only one person in her home sustained a brown recluse bite. So it is safe to say that these spiders, although venomous, are reluctant biters.

Nine out of ten times a bite from a brown recluse will heal on its own with no problems, but ten percent of the time this is not the case. When a recluse bite begins to necrotize the skin around the bite then you need to visit the ER as quickly as possible. If you do see a brown recluse spider, stay away from it, and call your pest control authorities if you don't feel comfortable with these spiders in or near your home.

Have you ever spotted a brown recluse spider in your home? If you have then how did you handle its presence?
