Spiders vary on the types of venom they produce to help them hunt their prey. Only a few species of spiders have venom that will affect a human being. Other than those with more sensitive immune systems, there are only a few species of spiders that can cause a deadly reaction. In the state of Pennsylvania there are three of our local species that are considered to be some of the most dangerous. Pest Control Technicians, Inc would like to share a little bit about these top three spider species that all local residents should be mindful of.
A wolf spider is one of the less dangerous species on the Pennsylvania spider list. However, they are definitely considered a threat. Wolf spiders don’t have deadly venom. However, what they do have is one of the most painful bites among all spiders. A wolf spider bite is quite painful and can cause major swelling and redness. There are some that might require medical aid to help them manage the pain. Wolf spiders prefer to spend their days outside and hide in wood or in yard debris. Their coloring helps camouflage them and most encounters are accidental. When they feel threatened, the wolf spider will bite. Keep in mind that some can have a serious allergic reaction to the bite. Wolf spiders are a larger species, measuring over an inch in length. They are covered with fine hair, much like a tarantula. They are mostly brown in color with darker marking on their body and legs.
Sac spiders are a common family group that is found throughout Pennsylvania. Sac spiders are found hiding in plants and around flowers, but will also invade homes and buildings. Inside, they will nest near window seals or along the corner of walls. Sac spiders vary in size and color. Most are smaller than an inch in length and they are yellow in color. When threatened, Sac Spiders will bite humans and again, their venomous bite can be painful. It can cause edema and severe itching. Some people have had a more severe reaction to the sac spider bite where they developed a fever, malaise, muscle cramping and nausea. Often accompanied with their painful bites comes nasty necrotic lesion around the site of the bite.
Southern Black Widow Spider
Another spider residence of Pennsylvania is the Southern Black Widow spider. There are many species of black widow spiders that can be found throughout America. Pennsylvania has the Southern Black Widow spider. Like all black widow species, the female carries the neurotoxin venom that can cause fever, chills, increased blood pressure, burning pain, muscle pain and shortness of breath. There have been cases of death due to a black widow spider bite, especially in the young and elderly. Most people know a black widow spider when they see one. However, most black widow spiders hide during the day and come out at night. A common sign of their presence are their spider webs. Black widow spiders will build webs near dark holes where they hide. The webs are typically messy with no distinct pattern.
