Even in North America there are three different types of the black widow spider and their classification is made according to the geographical area where they live: there is the northern black widow, the southern black widow and the western black widow; thus the species is widely spread from the south of Canada to Mexico. 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. Very seldom would one take a photo or a drawing of a poisonous spider and try to compare it with a specimen identified in open air. Camel Spider Lots of scary stories and myths about the camel spider often give people the creeps: the word goes that this species can eat out flesh portions after injecting a form of anesthetic in the victim's body, not to mention that its dimensions are truly impressive. The truth is somewhere in between: the camel spider lives in the Middle East countries, and it has become known in the United States and the rest of world after US troops have come across some specimens. The result of such a bite is known as loxoscelism, and it may appear in cutaneous and system manifestations. On a regular basis there should be no necrosis associated with a brown recluse spider bite, yet, some people are exposed to systemic reactions. The most risky of situtations have been registered in the case of children under seven, who have been bitten by this insect; an equally high risk is present with people that have a very fragile immune system. Most bites occur when one accidentally stick their hands into such secluded areas and corners or when the spider gets pressed against the skin. Wearing some rubber gloves when cleaning up around the house will help you avoid being exposed to a direct contact with the brown widow spider. The hourglass mark specific to all widow spiders colored in yellow or orange remains a distinguishable characteristic on the bottom of the abdomen. The hobo spider is often found in homes or in their vicinity and though the general reputation of the species is that of high aggressiveness, these creatures are very unlikely to attack a human being. You can only be exposed to a hobo spider bite in case you accidentally crush one; the bite is pretty painful due to the toxicity of the hobo spider venom.
