The hobo spider refers to a non-native spider species that has its origins in Europe and the United States. They accidentally appeared during the 1920s in overseas crates and packages. Hobo spiders are brown without any special markings, but have bites that are possibly dangerous and come with very distinctive hobo spider bite symptoms.
Almost 50% of the people who get bitten by a hobo spider will not get hobo spider bite symptoms, though, because they get dry bites. This means that the spiders simply were not able to inject their venom into them.
If venom does get injected, the area will turn number in 15 minutes and other body parts, like the tongue, will get numb, too. It will also start to turn swollen, hard and red in 18 hours.
A day later, the bite will begin to blister right in the wound’s center. This is when the victim might start to experience bad headaches, as well, and suffer from auditory or visual hallucinations.
By day two, the blister should break open and fluids should ooze out of it, after which it should scab over after 3 weeks. If the cases are extreme, though, the area could turn black after a few more days and a week later, the bite’s area of flesh might rot and require surgery.
Hobo spider bites always leave scars and in several cases, it could take a few years for the bites to fully heal. However, the hobo spider bite symptoms will be long gone by then.
