The Harmless Domestic Spider The hobo spider, also known as the funnel web spider, the hobo spider is a harmless species that lives both in Europe and on the North American continent. The specificity of the hobo spider is related to the way it weaves its web: the funnel-shaped nest is the perfect structure to wait for prey in. 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. Nevertheless, besides this self-treatment you should also seek professional medical health since brown recluse spider bites are not to be taken lightly. Other measures meant to improve the victim's condition include the elevation or the immobilization of the body part if the bite has been made on one of the limbs. Brown Recluse Spider Belonging to a small-sized arachnid species, the brown recluse spider is the one to be found in shady corners both indoors and outdoors. Unlike most other spiders that grow in our homes, the brown recluse spider does not weave a web, but creates an apparently disordered thread shelter. Spider Bites Though most people fear spider bites because of the nasty symptoms associated with them, sometimes there is nothing to worry about, as a small skin wound is no threat for one's health. Not all spider bites are dangerous, since the majority of spider species are totally harmless for humans; with the exception of a few venomous ones, the rest are pretty safe. There are several other varieties related to the black widow spider; they live in South Africa and Australia, and the major difference from the North American black one is of color: they are red and brown. 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.
