The Brown Recluse Spider in New Jersey - Identification, Bites, and Prevention

The Brown Recluse Spider in New Jersey

The brown recluse spider, also known as the violin spider or Loxosceles reclusa, is one of the most feared spiders in the United States. This is due to its venomous bite, which can cause severe skin lesions and other harmful reactions in humans. But how common are brown recluse spiders really in New Jersey?

Overview of the Brown Recluse Spider

The brown recluse is a small spider, usually measuring between 6-20 mm (0.25-0.8 inches). They have a violin-shaped marking on their cephalothorax (the fused head and thorax area), which is how they got their violin nickname. Their bodies are a brown or tan color, and they have six equal-sized eyes arranged in pairs.

Brown recluse spiders build irregular webs that are almost always spun in quiet, secluded locations like attics, closets, sheds, and garages. They prefer to live in dry, abandoned areas and only venture out at night to hunt.

These spiders get their name from their shy, reclusive behavior. They are not aggressive insects and will only bite when threatened or pressed up against the skin. However, their venom contains a cytotoxic agent that breaks down skin tissues, so their bites can cause slow-healing wounds.

Are Brown Recluse Spiders Common in New Jersey?

Although the brown recluse spider has a wide range across the southern, central, and midwestern United States, established populations are rare in the Northeast. New Jersey lies far outside of the brown recluse's native region.

That said, a few brown recluse spiders have been spotted and documented within the state. Most of these sightings likely stem from hitchhikers - spiders accidentally transported into the state in boxes, furniture, or vehicles coming from endemic areas down South.

So while isolated brown recluse spiders may exist in New Jersey, there are no known established breeding populations. The chances of running into one of these spiders is very low compared to states like Oklahoma, Arkansas, and Missouri where they thrive.

Identifying a Brown Recluse Spider

If you do spot a spider that you suspect could be a brown recluse, there are a few key identification points to look for:

• Violin-shaped marking on the cephalothorax - This is the most distinct feature and how the brown recluse gets its nickname. The violin marking may appear slightly different among individual spiders but it will always be present.
• Uniform brown/tan color - Brown recluse spiders have a solid brown or tan color. They lack stripes, spots, or other distinctive markings on their legs and abdomen.
• Six equal-sized eyes - Their eyes are arranged in three pairs, unlike spiders that have large prominent anterior median eyes (like orb weavers).
• Long, thin legs - Their legs are uniformly colored and do not have bands or stripes.
• Body size - Brown recluses typically measure 6-20 mm (0.25-0.8 inches) in body length as adults. Their legs span about the size of a quarter.

If the spider you find matches this description, it's best to exercise caution while handling and capturing it. The brown recluse has a venomous bite, so it's wise to keep your distance.

Preventing Brown Recluse Spider Infestations

While brown recluse populations are minimal in New Jersey, you can take some basic precautions to help discourage them from taking up residence in your home:

• Eliminate clutter - Brown recluses like to hide away in dark, enclosed spaces with lots of stuff stacked up. Keep closets, basements, attics, and sheds organized and free of excess clutter.
• Seal cracks and crevices - Seal any cracks, crevices, or holes that could allow the spiders to sneak inside. Pay attention to windows, doors, attic entrances, and exterior walls.
• Reduce moisture - Fix water leaks and humidity issues that could attract the moist-loving spiders. They like damp, humid areas.
• Keep vegetation trimmed - Prune back bushes, plants, and mulch several feet away from the home's foundation. This discourages spiders from crawling up to the structure.
• Install lighting - Add motion-sensor exterior lighting and leave some interior lights on at night. The nocturnal spiders will avoid brightly lit areas.
• Vacuum regularly - Use a vacuum to eliminate webs and potential spider hideouts inside. This also removes food sources like dead insects.

In addition, be very cautious when bringing home second-hand furniture, storage boxes, or other used items, especially if they're from known recluse states. Thoroughly inspect and clean all surfaces first.

What to Do If Bitten by a Brown Recluse

Brown recluse spider bites are rare in New Jersey, but still possible. Some key steps if you suspect you've been bitten:

• Wash the bite area - Use mild soap and water to gently wash the bite site and remove any lingering venom on the surface of the skin.
• Apply a cool compress - Place an ice pack (wrapped in a towel) or a cool, wet washcloth over the bite to help reduce swelling and inflammation.
• Elevate the wound - If possible, keep the affected limb elevated above heart level to slow venom spread.
• Avoid home remedies - Things like applying tourniquets, sucking out venom, electrical shocks, and freezing can cause further injury.
• Monitor for symptoms - Look for pain, itching, redness, swelling, blisters, ulcers, and purple discoloration around the bite.
• See a doctor promptly - Make an appointment or visit urgent care to have the bite evaluated and treated properly.

Though uncommon, some people can develop severe reactions to a brown recluse bite. Quick medical treatment helps reduce complications like prolonged healing, scarring, infections, and necrosis (tissue death).

With prompt care, most recluse spider bites heal fully within a few weeks. Elevation, rest, topical antibiotics, pain medication, and wound dressings are common treatments.

Other Venomous Spiders in New Jersey

While brown recluse sightings are highly unusual in New Jersey, there are a few other venomous spider species that residents should watch out for:

Northern Black Widow

The northern black widow is spread across the northeastern United States and commonly found throughout New Jersey. The females have a distinctive red hourglass marking on their jet black abdomens. They like to build their web nests in wood piles, tree stumps, and dense vegetation.

Though rare, their neurotoxic venom can cause muscle spasms, abdominal pain, and nausea when they bite humans. Seek medical attention promptly if bitten.

Yellow Sac Spider

Yellow sac spiders are one of the most common house spiders encountered in New Jersey homes. As their name suggests, they have yellow sac-like bodies and build silken tubes or sac webs in crevices and corners.

When they bite people, yellow sacs inject a mild venom that causes redness, swelling, and mild stinging. Their bites are rarely medically significant.

Hobo Spider

The hobo spider is native to the Pacific Northwest but has spread to parts of the Northeast including New Jersey. They are large, fast-moving spiders with a herringbone pattern on their bulbous abdomens.

Though there is still debate, some research suggests the venom of the hobo spider may cause severe skin lesions like the brown recluse. Seek medical help if you suspect a hobo spider bite.

Being aware of spiders that can bite around your home is important for prevention and prompt treatment. Though most spider bites have mild reactions, it's best to avoid contact and handle these species very gently if discovered.

Frequently Asked Questions

Where in New Jersey are brown recluse spiders most often found?

There are no concentrated populations of brown recluse spiders anywhere in New Jersey. The rare spiders that are found in the state are usually individual hitchhikers brought in from endemic areas through vehicles, boxes, or furniture. They do not reproduce and establish colonies in the wild in New Jersey.

What should I do if I find a brown recluse spider in my New Jersey home?

If you find a spider that resembles a brown recluse inside your home, carefully capture it in a jar for identification. If it is confirmed to be a brown recluse, thoroughly inspect the room and use glue boards or other traps to look for additional spiders. Seal any potential entry points they could use to get indoors. Continued sightings may signal a larger underlying issue that requires professional pest control.

How dangerous are brown recluse spider bites?

Most brown recluse bites do not inject enough venom to cause significant effects. In rare cases though, their venom can trigger severe local skin injury, intense pain and itching, fever, nausea, and systemic illness. Prompt medical treatment is vital for serious recluse bites.

What happens if a brown recluse bite goes untreated?

Leaving an untreated brown recluse spider bite can lead to much more extensive damage and complications. The venom destroys skin tissues, causing wounds that enlarge and turn into necrotic ulcers. These deep, rotting wounds often require surgical intervention like debridement and skin grafting.

Do brown recluse spiders live in groups?

No, brown recluse spiders are solitary and do not live in groups or colonies. They build individual retreats in out-of-the-way places and interact with each other very minimally. Multiple recluses may inhabit the same building in search of food, but each constructs its own silk retreat.
