The next thirty six hours are crucial for the evolution of the condition, since it is now that a deterioration or an improvement may occur; generally speaking, the ulcer and the necrosis will only appear within a few days if the health status does not improve. Once the venom has got into the system, there is a whole range of symptoms that accompany the brown recluse spider bite: vomiting, nausea, fever and muscular or joint pain have been among the most frequently reported. Even if hobo spiders live both on the American and the European continents, there is no difference in terms of physical specificity or venom composition. The treatment of the hobo spider bite is common with any other procedure applied to puncture wounds; let the bite bleed so as to eliminate as much venom as possible and then clean it with some topical antiseptic. As their very name suggests they enjoy very retreated corners where they are not bothered by light or intruders: cellars, garages, hallways or any other dark house area. Moreover, brown recluse spiders are very likely to be found behind paintings or under desks and tables. Brown recluse spiders are also very special by the way they have the eyes located on the body. Typically hairy, the wolf spider can be brown or gray with all sorts of markings and lines on the back and the abdomen. The special thing about these creatures is the way the females carry the egg sacs with them, and once the eggs hatch, the siblings remain attached to their mothers' back until they are large enough to detach and start a life on their own. This species likes to live undisturbed in quiet places like the cellar, the garage, sheds and other locations that are neither too humid nor too bright. 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 bite of the same poisonous spiders may trigger different reactions in separate individuals, since personal sensitivity to the toxins in the venom matters a lot. In geographical areas where poisonous spiders are known to live, people often learn how to differentiate them from the non-toxic species that are frequently encountered around the house.
