All spiders need to inject venom in order to survive, it is in the nature of their species and one of the life mechanisms they have been endowed with; what really differs from one species to another and gives rise to the classification into poisonous and non-poisonous is the amount of venom and its toxicity. Quality photos or drawings as well as proper descriptions of the species are necessary when trying to distinguish between the various spiders that live so very close to us. Homemade traps and low toxicity plant-extract pesticides are often used against the poisonous inhabitants of our houses that can give us some very nasty bites. Sometimes a spider bite can have very few local marks and it is only identified by the symptoms. The physical reactions to a spider bite are usually classified into local and systemic; the former can be treated at home right after the occurrence of the accident, whereas the latter often require professional medical treatment in order to reduce the reaction of the body to the venom. It is actually very likely to take a skin infection with a staphylococcus for a brown recluse spider bite, hence it is good to know that such injuries are rare and accidental. Brown recluse spiders are small, with an overall adult size that does not go beyond twelve millimeters; males are small then females, but they have slightly larger feet. 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 bites of these spiders are not dangerous, though sometimes nasty symptoms may appear: itching, swelling and even pain are among the most frequently encountered. 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.
