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. A bite exposes the victim to a whole series of unpleasant symptoms that require immediate medical intervention. Nevertheless, extreme attitudes towards poisonous spiders give rise to phobias and the urge to destroy their nests even in the wild. Keep in mind the fact that these creatures will not attack unless they feel threatened, as a human is no prey for their match. 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 consequences of the exposure to the venom of hobo spiders are less serious than the bites of the brown recluse spider for instance. However, people who have been bitten may expect to experience headaches and a general feeling of malaise. Sometimes, even vision problems have been reported, but under such circumstances you should contact the doctor right away and receive professional help. House species are the first to require proper spider identification since they are the first we come into contact with, and, on certain occasions, it is pretty difficulty to tell them apart. This is the case with the house spider, the giant house spider and the hobo spider; they all live indoors, but only the latter is a real threat to humans, since its bite can cause necrosis. In the majority of cases medical assistance is not necessary and a bag of ice placed on the bite will do. If discomfort does not cease, you should not postpone seeing a doctor. Although trapdoor spiders are not generally dangerous, some people may experience very strong reactions to the venom, like nausea, vomiting and headaches.
