What kind of spiders are in Maryland?

The most naturally occurring venomous spider in Maryland is the black widow spider. This spider has been in Maryland for a long time, but many claim that it was brought to the state via other people’s stuff and personal items. We will delve deeper into the most common species, behavior, characteristics, and habitats of poisonous and non-poisonous spiders in Maryland.

The Crab Spider

The crab spider is widely seen on flowers outdoors. They are colored white, yellow, and red and the spider legs are found protruding from the sides that make them look like crabs. They cannot live indoor and are not poisonous. These spiders cannot survive indoors. They are also not poisonous.

The Jumping Spider

You will often see the jumping spiders on the ceiling in late fall. They are hairy and have a black color and a lot of people often mistake them as black widows. These jumping spiders do not have the hourglass shape similar to those of the black widow spider. These spiders are so-called because they often jump and run very fast. They can have a span a span of one–inch and have white or red dots surrounding them.

The Cobweb Spider

The cobweb spiders enter any house or structure as a small creature and establish a home by spinning webs to catch insects to prey on. If you happen to see their web, you can clean them up and smack the spider down. If you can keep your home free from spider webs, you will not have any problem with any species later on. The cobweb spiders are not poisonous.

The Yellow House Spider

Yellow house spiders are approximately a quarter of an inch in length and they come with a yellow-green body and a much darker color around the legs. The yellow spiders move very fast. They would enter any house around fall where they will hide and create homes until springtime. They would spin webs in very dark and confined locations in the house.

The Cellar Spider

The cellar spider is more commonly found indoors rather than outdoors. Cellar spiders have long thin legs, and a relatively small body. These are harmless creatures with venom which is as poisonous as other Maryland spiders. When disturbed or threatened, cellar spiders vibrate their bodies to make it look like its a larger object, while at the same time this makes it tougher to hit. Humans are not immune to the venom but since these cannot bite deep, these are not threats to humans.

The Wolf Spider

Wolf spiders have leg length of approximately 2 inches. This species is often found outdoors and rarely indoors and they can go inside log cabin homes that are surrounded by many trees. They have brown and a dark grey spots all over its back. Wolf spiders are mildly poisonous and the bites from these spiders can lead to very mild itching or burning sensation. But, many individuals experience some allergies when bitten and if you are one of the unlucky few, you have to immediately seek medical help at the first sign of a spider bite. The Maryland wolf spider can come inside a home in the late fall where they can feel it’s getting rather chilly outside. Wolf spiders can invade your basements at home. Care should be taken with wolf spiders.

The Brown Recluse Spider

Maryland is home to a variety of spider species but not all of them are natives. The brown recluse spider is another species which is not native to the place, but it is often seen all around the state. Brown recluses are not native to Maryland, but came to the state via people transporting to and from the place. They may have come with the people’s luggage and clothes as they moved all over Maryland. If someone has been badly bitten by brown recluses, they should catch it in a jar, and cover it safely with a tight lid. Bring it with you to a medical professional, and seek immediate assistance.

What is the largest spider in Maryland?

Many spiders are huge with amazing leg span, girth, and length that can only be found in Maryland. In the US, especially the mid-eastern portion, many spiders can reach their full size around late summer or early autumn. The largest of spiders in Maryland are often seen late in the year. But, many spiders such as the fishing and the wolf spiders may be found at amazingly large sizes throughout the year.

The largest spider found in Maryland is the Dark Fishing Spider otherwise known as the ‘Dolomites Tenebrosus.’ Fishing spiders can span the length of 1.5”. Next in size is the Carolina Hogna spider at 1.4” in length. The Orb Weaver is known as the heaviest spider of all, although it is not the largest.

Does Maryland have poisonous spiders?

A lot of the spiders that are found in the Maryland area have venom, however, it is the black widow spider that is regarded as a native spider that is very dangerous to humans. All other poisonous spiders found in Maryland have little to no venom at all and they can cause very little harm to their unsuspecting human prey.

The brown recluse spiders are not native to the place, however on very rare occasions they can hide in some things that are shipped to the area from the southwest and the midwest, hence the name recluse. About ten percent of the brown recluse spider bites can lead to cellular death or tissue necrosis. Researchers are realizing that those who were previously bitten by the brown recluse spider were, in fact, MRSA infections (methicillin-resistant Staphylococcus aureus). The treatment for this sort of infection and other spider bites are the same. The brown recluse is often known for its distinct characteristics like the dark violin-like shape on the head, 6 pairs of eyes, uniform, and light-colored legs with no stripe, they have no spines around its legs, and the body spans 3/8-inch in length. If you don’t know how to eradicate these spiders, you should seek pest control.

The spider bites are not uncommon to people in Maryland and many spiders would only bite humans in self-defense to protect themselves or their habitats. Although these insects come with fangs, they are very tiny to even leave some puncture wounds. Oftentimes, the spider bite will result in redness, itch, swelling, or pain that can last anywhere from one to three days. The spiders do not bite more than once, and so when you see several bites, these bites may be caused by other insects such as bedbugs, fleas, mites, chiggers, flies, and or ticks.

Even though spider bites from the brown recluse or black widow are considered very rare, care and extra precaution must be taken to easily spot and help cure the wound fast. Adults can experience very mild symptoms, however elderly and young children can have their immune system and overall health compromised and they have to be very careful getting these spider bites. If your house has these types of spiders, call for assistance with pest control.

Avoid the black widow’s common hiding places like the following:

  • Tool sheds
  • Trash pile
  • Lumber pile
  • Water meter box
  • Old shed
  • Woodpile
  • Flower pots
  • Cardboard box
  • Basket
  • Mailboxes
  • Window wells in the basement
  • Under porch and yard bench

Are wolf spiders dangerous?

Generally, the wolf spider is regarded as a venomous spider but its bite is not lethal. Wolf spiders are not aggressive and will only bite when they are provoked and they are rendered dangerous to people. The bite of the wolf spider is very painful.

The Maryland spiders are a crucial predator of many other noxious pests and they are on top of the hierarchy of invertebrate predators in various ecosystems. Although your home or yard can be home to many spiders, the probability of a spider bite that is poisonous is very low as long as you respect their space and they are not handled roughly. They only attack whenever they feel that their life and safety is at stake.
