Despite its diversity, all the huntsman spider specimens have eight eyes disposed on various parts of the body, and a good vision for the close and distant potential pray. Unlike the general opinion that associates spiders with webs, this is not the case with the huntsman spider: this species goes out to hunt its pray as it doesn't wait for it to get caught in a web. In the United States, hobo spiders are considered a real danger since their bite can cause severe necrosis; nevertheless, the reported cases are pretty rare, as the most likely symptoms to appear include local pain, itching and swelling of the bitten area. Aloe vera, ice chips and antibiotics applied on the bite are thought to reduce the discomfort and speed up healing; yet, none of them is considered a 100% reliable remedy for hobo spider bites. The immediate drug treatment of risky spider bites usually includes the administration of an anti-venom based on corticosteroids. The administration of specific medication can only be done by authorized medical personal and when the circumstances indicate a toxic venom exposure. Contact a health care provider immediately if you've been bitten by a spider and you experience fever, nausea, swelling of the tissues and severe pain. All spiders depend on their venom for survival: venom is the way to hunt and defend themselves, but from the many thousands species only about two hundred actually represent a threat for human health. The great thing about these creatures is that they have adapted to the harshest of environments from the desert and the tropics to the Arctic areas where they can live underwater. Reactions to spider venom vary from one person to another, and the same rule stays valid for the treatment, which is why a remedy that has worked for a person is not necessarily going to be the perfect choice for another. The doctor's advice is therefore crucial under such circumstances since the worst scenario of a spider bite is possibly death when the action of the venom is taken to the extreme, and help can only be found in a professional medical facility. The Brown Recluse Spider Brown recluse spiders, also known as the fiddle-back spiders or the violin spiders are America's most widely-spread and harmless arachnid species. They are found almost everywhere on the North American continent except the area at the west of the Rocky Mountains; what seems even more interesting is the fact that a variety of brown recluse spiders is also found in Hawaii.
