A Spider bite can be referred to as a puncture to the skin, inflicted by a spider, or other members of the arachnid group. Concern about a spider bite, is usually due to the properties of its venom. A spider transmits its venom through the puncture in the skin, this puncture may raise concerns about the transmission of an infection, however not all spiders will transmit their venom through a bite. A Spider’s venom may be either neurotoxic or necrotoxic. Neurotoxic venom will attack the nervous system, while necrotoxic venom attacks any tissue that surrounds the bite, and sometimes organs.

In reality, there are approximately 20,000 species of spiders, all of which are different, and only sixty (60) of them are able to bite a human being, four of which are unsafe for human beings. They are, the brown recluse, the famous black widow, the hobo, sometimes called aggressive house spider, and the yellow sac spider. Of this four, only two have been known to cause disease and death, the brown recluse, and the black widow.

They are normally equipped with toxins, that are strong enough to cause the nerve cell function improperly, as well as, cause muscle cells to twitch.
A brown recluse does not have to be brown; its color ranges from tan to dark brown, and it has legs that are about one inch in length. A brown recluse, can usually be spotted with a violin-shaped mark on its chest. They are mostly found in the southern central areas of the US.
