Facts and Information about the Poisonous Spiders Did you know the following facts about Poisonous Spiders? All spiders are venomous and don't attack humans rather they defend them selves from being squashed and when they feel threatened. For example, as we sleep we often move about, and its natural for us to move when something tickles us, such as a spider looking for prey, this results in us moving our arms and legs making the spider think its under attack, so it will bite to defend its self and run away. Some spiders can be aggressive but only if provoked so a case of self defence again. Between 98 and 99% of spider bites are harmless, with some bites resulting in harmful symptoms such as necrosis, being the premature death of cells and living tissue, but in most cases, the most someone will experience is nausea, itching, stinging pain, redness and swelling. Some bites damage our nervous system. The more dangerous spider bites can result in, extreme cases, death if untreated. This rarely happens as bites can be treated.
