Many people fear finding wolf spiders in their Ewing homes and offices, but the appearance of this arachnid is more threatening than its personality. In fact, there are a number of spiders that closely resemble the wolf spider in that they are large, dark and covered in dense hair. However, it is usually the wolf spider that has the most fearsome reputation.
This may be attributed to its name. While some people think that wolf spiders get their name from their heavy fur, this is not the case. Long ago, a scientist theorized that this species of spider hunted in packs much like wolves do. He named the spider accordingly, but it turned out that his theory was wrong. Although wolf spiders are adept hunters, they hunt alone rather than in packs.
This may not bring much comfort to people who have an extreme dislike for seeing these large spiders inside their homes. Asking an exterminator to address the issue is the best way to ensure a guaranteed and swift resolution. This is because control of any spider species is more complex than it may appear. Thanks to the multi-pronged approach of integrated pest management, it is possible to reduce the spider's food supply, thus forcing him to look elsewhere for a meal.
Size: Up to 1.5 inches in length
Color: Brown, grey, black, and sometimes orange. Some are striped,spotted, or monochromatic.
Characteristics: Wolf spiders are known for their large size and hair legs. Because of this, they are often confused for brown recluses or tarantulas.
The species are not picky eaters. Practically all insects and invertebrates are on the menu, even when they are far larger than the hunter. Large female wolf spiders have been observed eating amphibians and reptiles.
Unlike other spiders, wolf spiders do not build a web in which to catch a meal. Instead, they are active hunters, but their methods vary according to species. Some will trek across floors or the ground, looking for likely prey. When they spot an insect, they rapidly pounce and bite the prey to immobilize it. Other subspecies will construct a tunnel in which they hide. When an insect walks by, they jump out and grab it.
Unexpectedly shy and retiring, wolf spiders do not go out of their way to bite or even frighten people. They prefer to avoid confrontations, which is why they are inclined to lurk in dark, cluttered spaces. Nonetheless, their size and appearance do make them seem threatening to people, and many families are uneasy when they know a wolf spider infestation is underway.
Not considered poisonous, the wolf spider's bite nonetheless does transmit a mild toxin. Slight pain, itchiness and swelling are common reactions after a bite, but most people tolerate these well and heal within a couple of days.
Some individuals are allergic to the spider's venom, which may cause them to experience more severe reactions. An allergic reaction may be characterized by fever, difficulty breathing, dizziness, cramping, headache and cramps around the area where the bite occurred. Seeking medical advice is wise, and antibiotics and antihistamines usually are sufficient to bring the condition under control.
