Prevention, Most spiders are not poisonous (although they can inflict a painful bite). The most common poisonous spiders are the Black Widow and the Brown Recluse. Both are shy and tend to hide out in woodpiles,

quiet nooks and crannies, and other out-of-the-way places – perfect for unsuspecting fingers to find them (surprise!) while reaching into the woodpile.

Always wear gloves when handling stacked wood or other stored materials. Keep corners and debris piles cleared out and swept up (good housekeeping!).

Treatment, Apply cold (ice or cold water). If possible, take an antihistamine, and use a topical antihistamine or hydrocortisone cream.

If you didn’t see they type of spider that bit you, watch for pronounced swelling (Black Widow), or a small ulcerated spot at the bite location (Brown Recluse). Seek medical treatment right away in either case. Source: USFWS Outdoor Safety

Black widow spider From Wikipedia, the free encyclopedia, The black widow spider (Latrodectus mactans) is a spider notorious for its neurotoxic venom.

It is a large widow spider found throughout the world and commonly associated with urban habitats or agricultural areas. Although the common name 'black widow spider' is used to refer specifically to L. mactans it is occasionally also applied to several members of the Latrodectus (widow spider) genus in which there are 31 recognized species including the Australian red-back and brown widow spider. In South Africa, the black widow is also known as the button spider.
