Inevitably, you will get into contact with a spider sooner or later, either indoors or outdoors; the general tendency is to destroy their nests inside of our homes since we associate cob webs with a messy and unclean area. Last but not least, certain spider species are a real threat to humans by the damage their venom can do to us. In North America for instance, poisonous spider identification is a thumb rule for anyone living close to such creatures; there are not too many species of the kind, hence, once you learn how to set them apart you can relax and feel a lot safer. 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. Unlike other spider species that have four pairs of eyes, brown recluse spiders have only three: one medianly located and the other two pairs lateral. If you suspect to have been bitten by such a spider, it is good to keep a close watch on how the condition of the affected area evolves. There should be no pain felt at the beginning, as reactions only appear within two or up to eight hours after the bite. Hives, wheezing, shortness of breath and weakness are the general symptoms associated with anaphylaxis, therefore call 911 right away if you notice any such symptoms. Other systemic reactions to spider bites include leg cramps, leg numbness, headaches, pulse changes, exhaustion and more, they are all serious enough to determine one to call the doctor right away. Tree bark, crevices and even garages and sheds are the favorite places where the huntsman spider would make its home. Because of its high adaptability to the environment, it will cling very easily thanks to its articulate legs. Thus, if you get a huntsman spider on your clothes, you'll find it pretty difficult to shake it off. The easy way to distinguish between males and females is not just body size, but also the length of the articulated feet. One other peculiarity of the camel spiders consists in the presence of several pairs of eyes grouped on various body parts. Thus, they may look more like spiders, but the visual accuracy is considered superior by many researchers.
