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. 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. 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. The local symptoms associated with a spider bite include pain, itching, redness and even swelling of the area; their intensity can be reduced if a tight bandage is applied above the wound. 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. The males are likely to leave their nest and go hunt somewhere else, while the females will not go far from the web. 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. 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.
