A test has been created to identify the wound and the venom type, but the practice is not part of the medical routine yet. Lots of doctors recommend a minor surgical intervention in the tissue area affected by the venom, yet the excision could impair the recovery as such and may increase the risk of scarring. For such cases spider identification is not necessary; but we cannot say the same thing about the widow spiders that require the immediate use of an anti-venom. Therefore, spider identification can be crucial when you need to be able to apply the right treatment without any further delay. Spiders that live outdoors are more difficult to identify due to the large number of species both harmful and venomous. The greatest risk of a spider bite is anaphylaxis: the allergic reaction to spider venom that is sometimes encountered with very sensitive people. Hives, wheezing, shortness of breath and weakness are the general symptoms associated with anaphylaxis, therefore call 911 right away if you notice any such symptoms. The black widow spider is not capable of killing a bird that would eat it, but the digestive sickness that would follow, will be definitely enough to make it avoid attacking the black widow again. The female black widow spider is more venomous than the male, and it is she the biggest threat to predators. Sometimes, even vision problems have been reported, but under such circumstances you should contact the doctor right away and receive professional help. Nevertheless, it is a good idea to stay calm since anxiety adds up to the severity of the symptoms and that is surely the last thing you'd like to do. However, the bite is not as serious as that of a tarantula for instance, since the camel spider has no venom to inject. The only venomous species variety grows in India and it is not such a real threat to humans at all; moreover, the camel spider will not attack a prey that is larger than itself, hence the myths and rumors are definitely far-fetched and unworthy of consideration.
