Wolf spiders are commonly mistaken for many spiders appearing large and brown and fur-covered. However, numerous spiders could answer this description without being actual wolf spiders.
This is why it is critical to ask a professional to identify spider species. Getting the identification right is the first step toward using the correct control measures. Additionally, controlling the spider population is difficult. They are not threatened by ordinary bug sprays the way that insect species are. Controlling wolf and other spiders that gain entry in homes and businesses around the Philadelphia area typically requires specialized methods that may include eliminating their food source and making repairs that keep these pests outdoors where they belong.
WHAT DO WOLF SPIDERS LOOK LIKE? In North America, the easiest way to identify a wolf spider from other species is their eyes. Wolf spiders are equipped with eight eyes that are arranged in a row of four on the bottom with two large eyes above them. Two medium eyes are placed at the top and sides of the head.
Otherwise, identifying wolf spiders is made complicated by the fact that there are about 240 species of wolf spiders worldwide. Not all of them are found in North America. The ones that are generally have fuzzy bodies and legs and broad backs. Colors may include black, brown, gray and tan. Their cephalothorax and abdomen are approximately the same size.
Wolf spiders also may be identified by the three minuscule hooks located on the ends of their legs. These are used to help the spider maintain its grip while climbing and running. The two front legs are especially sturdy to help them hold onto prey. WHERE DO WOLF SPIDERS LIVE?
Wolf spiders prefer brushy areas, and they also like to hide beneath rocks and stones. It is not uncommon to find them lurking around yard debris piles or woodpiles. Coming indoors is not unusual, especially if they find a space that is dark, dusty and cluttered. Accordingly, people may encounter wolf spiders in garages, sheds, attics, basements and crawlspaces. Even inhabited spaces may be invaded if there is sufficient clutter offering good places for concealment.
WHAT DO WOLF SPIDERS EAT?
Wolf spiders may eat a wide array of insects and invertebrates. Some especially large females of the species also may eat small reptiles and amphibians. It is not unusual for wolf spiders to attack insects that are bigger than they are.
Wolf spiders generally do not spin webs in which to catch prey. They hunt instead, and the methods they use vary according to species. For instance, some build a tunnel in which to hide, then ambush prey that wanders by. Others may walk along the ground surface seeking prey. When an insect happens by, they jump on the insect and take a quick bite.
DAMAGE CAUSED BY WOLF SPIDERS
This is not a destructive species, but many people experience distress whenever encountering a wolf spider. Given the arachnid's size and rather fearsome appearance, this is completely understandable. People who have discovered a wolf spider may feel uneasy until they know the problem has been resolved.
ARE WOLF SPIDERS AGGRESSIVE?
Although they are aggressive hunters, wolf spiders tend to be shy around people. Avoidance is their preferred method of dealing with humans, but they will bite if they are cornered or threatened.
A mild venom that is not overly toxic is released with the bite, but this usually is not harmful to people.
DO WOLF SPIDERS CARRY DISEASE?

However, medical treatment may be needed when the bite victim exhibits symptoms such as persistent headaches and dizziness, cramping around the site of the bite, sweating, a rash, nausea, trouble breathing or a fever. Antihistamines and antibiotics may be needed to reverse this reaction.
