If you have noticed flat, dense, webbing around your garage, eaves, doors or even in your basement, with a funnel-like area near the back you might be looking at an invasion of hobo spiders. There is a lot of debate about the hobo spider, and whether or not they are a risk to people. What is known is that they are fairly large, create quite a mess with their webs and often come into close contact with people during the summer months.
Although the debate continues as to whether or not the hobo spider bite is dangerous, the fact is that, like most spiders, they will bite if their webs are disturbed. Avoid hobo spider bites by calling Rentokil Steritech spider specialists to take care of any spider problems you might have on your property.
Hobo spiders are, many times, confused with the brown recluse spider. However, they are different in many aspects. They tend to build webs in very different locations and their appearance is notably different than the brown recluse.
Although there are many species of hobo spider and their appearances vary widely, some of the most common aspects to look for are:
The hobo spider is part of a species known as "funnel weavers." They are not to be confused with funnel web spiders, which are an entirely different species. However, they share a common trait in that their webs usually contain a kind of habitat or funnel area where the spider itself rests and spends most of its time.
In North America, hobo spiders create very visible, milky-colored webs in corners, cracks, bushes and even in the grass. They can grow quite large, sometimes covered in debris from falling leaves and other vegetation. Hidden within the large flat part are trip lines that lets the spider know that potential prey has entered the web.
The hobo spider is notorious for being very fast. Once prey hits the trip lines, they will move quickly to grab the prey, bite it, envenom it and then eat it.
Currently the hobo spider is labeled as a spider of medical significance. This means that it is thought that their bites could be harmful to people. There is some dispute about that among arachnologists, however.
The debate is whether or not hobo spider bites are "necrotic" meaning that they might cause lesions similar to that of the brown recluse. This was due to tests reportedly done by the CDC on rabbits where necrotic lesions appeared in animals injected with the venom. The problem is that other scientists have failed to reproduce these results and some say the supposed lesions were not necrotic at all.
Regardless of this, it is known that hobo spiders will bite. It can cause pain to humans, but they are not known to be fatal. The necrotic lesions that were seen were less severe than those seen with the brown recluse. Symptoms include headaches, dizziness, feelings of malaise, and vision problems.
Anyone who is sensitive to insect stings and bites, or who are unsure of what kind of spider bit them, should seek immediate medical attention. If it is possible, capture the spider that did the biting so medical staff can determine the correct course of treatment.
