Most bites occur when one accidentally stick their hands into such secluded areas and corners or when the spider gets pressed against the skin. Wearing some rubber gloves when cleaning up around the house will help you avoid being exposed to a direct contact with the brown widow spider. The hourglass mark specific to all widow spiders colored in yellow or orange remains a distinguishable characteristic on the bottom of the abdomen. 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. When a spider bites you, the first thing to do is trying to identify the species, if it be possible; knowing what type of spider bit you may be crucial in case an anti-venom has to be used. In terms of toxicity, the black widow spider has one of the most potent venoms in the animal world: it is actually fifteen times stronger than that of the rattlesnake for instance. It also surpasses the cobra and the coral snake in the effectiveness of the poison. Though death is not usually the outcome of a black widow bite, some dozens of cases have been reported over the last decades only in the United States. In North America for instance, poisonous spider identification is a thumb rule for anyone living close to such creatures; there are not too many species of the kind, hence, once you learn how to set them apart you can relax and feel a lot safer. House species are the first to require proper spider identification since they are the first we come into contact with, and, on certain occasions, it is pretty difficulty to tell them apart. The only variety of venomous camel spiders grows in India, but research is pretty scarce in the field. Apparently, the Indian camel spiders can hunt down lizards by injecting them with venom and paralyzing their movements. One of the natural enemies of the camel spiders, the scorpions are very likely to lose a fight against this giant arachnid. Once the venom has got into the system, there is a whole range of symptoms that accompany the brown recluse spider bite: vomiting, nausea, fever and muscular or joint pain have been among the most frequently reported. Though apparently harmless, the brown recluse spider bite is more serious than that of other more venomous and threatening species.
