Thus, if you get a huntsman spider on your clothes, you'll find it pretty difficult to shake it off. Far from being seen as a threat to humans, the huntsman spider is pretty useful since it mainly feeds on insects. Nevertheless, the Australian variety of the species has been reported to inflict serious bites that cause not just pain and inflammation, but vomiting episodes, fever, headaches and even changes in the heart rate. 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. The largest wolf spider will not be more than two inches in length, but on a common basis their size is variable and lower. Typically hairy, the wolf spider can be brown or gray with all sorts of markings and lines on the back and the abdomen. The special thing about these creatures is the way the females carry the egg sacs with them, and once the eggs hatch, the siblings remain attached to their mothers' back until they are large enough to detach and start a life on their own. 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. Aloe vera, ice chips and antibiotics applied on the bite are thought to reduce the discomfort and speed up healing; yet, none of them is considered a 100% reliable remedy for hobo spider bites. The consequences of the exposure to the venom of hobo spiders are less serious than the bites of the brown recluse spider for instance. Trapdoor Spiders Coastal and highland Australia is the favorite habitat of trapdoor spiders, a spider species that perfectly suits the description of the multi-legged predator. The favorite pray of trapdoor spiders includes grasshoppers, moths, crickets, but they don't back off when it comes to having small birds and scorpions for their meals too.
