The siblings will not appear for a few months after intercourse, and they will remain protected in the female's burrow until they are old enough to disperse on the ground. Among other species, trapdoor spiders have a pretty long life span from five to twenty years, and only the females make a nest, whereas males go out in the open hunting and looking for a mate. The specificity of their vision organs is the one that ensures the survival of the species since the wolf spider depends on the eyesight to hunt. Furthermore, as they spend most of their time at ground level, these creature also have a very well-developed sense of touch. The wolf spider is not an aggressive species, though it may bite if provoked or threatened. In order to avoid direct contact with spiders indoors, you can use special sticky traps that will drastically lower the risk of being bitten by a venomous species. 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. Webs are the distinct mark of spiders but even these have a particular imprint of their own: thus, some create sheet webs, others spiral webs, not to mention the true mazes that some dangerous species design as deadly traps for their prey. A clear example here is the distinct tangled web the black widow makes; yet, spiders also create webs for the protection of their nests. There is a whole range of symptoms, one nastier than the other that accompany the bite of a dangerous spider: digestive troubles such as nausea and vomiting, headaches and fever, not to mention the local discomfort manifested as pain and itchiness. The bite of the same poisonous spiders may trigger different reactions in separate individuals, since personal sensitivity to the toxins in the venom matters a lot. This precaution measure is only valid in case the spider bite is located at the level of the arms or legs. One other thing you can do is to put some ice or cold water on the bite in order to reduce the discomfort and alleviate the pain. You should be concerned when the symptoms do no improve within 24 hours and there is numbness or increase in pain.
