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. In the open air, the brown recluse spider is to be found in rotten tree bark which they inhabit naturally without being disturbed. There is one thing that definitely sets the brown recluse spider apart from other fellow-spiders: the way it hunts. The whole purpose of weaving a web or creating a maze of threads is to make the perfect trap for catching prey; yet, the brown recluse spider does not consider that enough. The shape of the web woven by the hobo spider is truly unique, it consists of a very dense silk sheet which is usually curved upwards so that insects that come from above the structure may fall into it. The hobo spider waits in a tubular retreat until the prey is tangled in the threads and only then it comes out and injects the insect with the paralyzing venom. Th color of the brown recluse spiders goes from tan to dark brown, and sometimes there may be an intense yellow pattern on the body too. The bite of the brown recluse spiders is likely to cause a whole range of symptoms at the skin level known as loxocelism, and the greatest risk they involve is that of necrosis. 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. A Bite from a Brown Recluse Spider Like other insect injuries, brown recluse spider bites are likely to cause lots of discomfort as they are behind the majority of necrotic wounds reported in the United States on a yearly basis. Though the spider species in question is pretty common and not aggressive, sometimes, their venom has a great impact on the system triggering a very violent response not only at the skin level but in the deep body structures as well.
