Nevertheless, extreme attitudes towards poisonous spiders give rise to phobias and the urge to destroy their nests even in the wild. Keep in mind the fact that these creatures will not attack unless they feel threatened, as a human is no prey for their match. The harm the spider venom can inflict depends on the fierceness with which the spider will defend itself. Though the generic name of the funnel web spider is used most of the time, it includes no less than thirty-six species that live both on land and in trees. The favorite habitat of the funnel web spider consists of the moist area under rocks, crevices, rotten trees, holes and tree bark. For the funnel web spider varieties that live in gardens, shrubs are the perfect place to make their nests. You may even find brown widow nests in buckets, mail boxes, entry corners, closets, garages and even in vegetation like shrubs and tree branches. 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 next thirty six hours are crucial for the evolution of the condition, since it is now that a deterioration or an improvement may occur; generally speaking, the ulcer and the necrosis will only appear within a few days if the health status does not improve. 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. One of the natural enemies of the camel spiders, the scorpions are very likely to lose a fight against this giant arachnid. Due to the extended size, the camel spiders are able to cut down the sting of the scorpion and make it harmless. The male camel spiders are smaller than the females, particularly since the latter will eat a lot before hatching. Hence, the ability to correctly identify spider bites is vital for the right treatment of necrosis. Experts in the field often say that spider identification is tricky since very many species resemble each other, and the venomous and the non-venomous ones are found in a complex who's who relationship.
