Wood Spiders in Connecticut: Bites, Identification & Treatment

Wood Spiders Commonly Found in Connecticut

Connecticut's wooded areas and suburban neighborhoods provide ideal habitats for many species of spiders. While the majority of spiders in the state are not dangerous to humans, there are a few wood spider species that can deliver a painful bite. This article will discuss some of the most common wood spiders found in Connecticut and provide tips on avoiding and identifying them.

Brown Recluse Spider

The brown recluse spider is one of the most feared spiders in North America due to its potentially dangerous venom. This spider is native to the south-central United States but over the years, isolated populations have been found in parts of New England, including Connecticut. The brown recluse prefers warm, dry, abandoned areas such as woodpiles, barns, and sheds. Its name comes from its tendency to be reclusive and avoid contact with humans.

Brown recluse spiders have a violin-shaped pattern on their body and range in color from tan to dark brown. They have six equal-sized eyes arranged in three pairs. Adult brown recluse spiders are about 6-20 mm in body length. Their bites contain cytotoxic venom that can destroy skin tissue and leave deep, painful wounds that take a long time to heal.

While rare, brown recluse bites have occurred in Connecticut. If you find this spider, it's best to avoid contact and have the spider safely removed by a professional.

Black Widow Spider

The black widow spider is another venomous spider that occurs rarely in Connecticut. It gets its name from the female's distinctive black body with a reddish hourglass marking on the underside of the abdomen. Male black widows are smaller and lighter in color. This species prefers warm environments and is most active at night when hunting for prey.

Black widow spiders construct irregular, tangled webs in protected spaces like woodpiles, tree hollows, and crawl spaces. The bite of a female black widow contains neurotoxic venom that can cause muscle spasms, abdominal cramping, and breathing difficulties in humans. Fortunately, antivenom is available to treat black widow bites.

While native to warmer regions, occasional black widow sightings do occur in Connecticut, especially in the southwestern and coastal areas. Caution should be taken around piles of undisturbed wood or debris that black widows may inhabit.

Yellow Sac Spider

The yellow sac spider is a clubionid spider found throughout most of North America. In Connecticut, it is one of the most commonly encountered wood spiders. Yellow sac spiders are Huntress sac spiders pale yellow to light brown, with a body size around 10 mm.

Yellow sac spiders do not build webs for catching prey. They are wandering hunters that live in silken retreats in crevices or holes, which gives them their "sac" name. In the wild, they inhabit spaces under bark or rocks. In residential settings, they can reside in vents, storage areas, window casings and indoor nooks.

The bite of a yellow sac spider can be painful but is generally not medically significant. Redness, mild swelling and irritation may occur. On rare occasions, a necrotic skin lesion may develop. Proper wound care and hygiene prevents infection.

Fishing Spiders

Several species of fishing spiders in the Dolomedes genus reside in Connecticut. Most fishing spiders have dark brown or grey bodies with white, brown and black markings. They get their name from their habit of waiting motionless at the water's edge and then rapidly skimming across the surface to grab insect prey like fishing lures.

Fishing spiders do not build webs for catching prey. Some make silk retreats for egg protection. Their legspan can reach up to 15 cm but they are not considered dangerous to humans. Bites may cause mild pain and swelling but have no long-lasting effects.

Wolf Spiders

Wolf spiders comprise over 100 species found throughout Connecticut and the United States. They are agile hunters with excellent eyesight. Wolf spiders have a variety of brown/grey colors and patterns that can camouflage them well on tree bark. Large species can reach 30 mm in body size.

Wolf spiders do not use webs or snares to capture prey. They actively chase down their quarry once detected. During the day, they reside in burrows under logs, rocks or leaf litter. At night, the spiders leave the burrows and hunt.

Female wolf spiders carry egg sacs with them until the spiderlings hatch. While intimidating, wolf spider bites are comparable to bee stings in pain level and effects. The bite may cause mild swelling and redness but is not dangerous.

Avoiding Bites from Wood Spiders

Most wood spiders typically avoid contact with humans and bites rarely occur unless the spider is unintentionally provoked or trapped. Here are some tips to avoid inadvertent bites when around wood spiders:

• Wear gloves and cover arms/legs when working in areas spiders may inhabit like basements, shed interiors, woodpiles, etc.
• Check areas before sticking hands in unseen spots to avoid surprises.
• Use caution when lifting debris, wood, rocks, yard items, etc.
• Keep living spaces decluttered and vacuum/sweep regularly.
• Inspect items thoroughly before grasping.
• Install screens on windows and doors and seal cracks in the home's exterior.
• Keep bedsheets/linens from touching the floor and shake them out before use.

Being observant and practicing caution outdoors and in infrequently used areas of the home can help prevent most spider bites. Having a general knowledge of venomous species in your region allows for wise actions if these spiders are encountered. Most Connecticut wood spiders play important roles as insect population regulators and are not aggressive unless accidentally threatened.

Identifying and Treating Spider Bites

Many spider bites look similar initially. The wound may appear as a small red mark resembling a mosquito bite or minor bee sting. Bites can also feel itchy or tingly. Here are some signs and symptoms that indicate a potential spider bite:

• Mild burning pain at the bite site
• Redness and mild swelling
• Small puncture wound visible
• Mild itching, tingling, or numbness

More severe spider bites may exhibit the following:

• Intense, radiating pain
• Extensive swelling and redness
• Nausea, vomiting, dizziness, fever
• Muscle cramps or spasms
• Skin lesions, ulceration, blackening tissue
• Difficulty breathing

If you suspect a serious spider bite, seek medical attention promptly for assessment and treatment options. Be sure to provide details on the spider's appearance and circumstances of the bite if possible.

For less severe bites, basic first aid includes:

• Washing the bite area thoroughly with soap and water
• Applying a cool compress to reduce pain and swelling
• Elevating the bitten limb if possible
• Avoiding scratching as this can spread venom
• Using an antibiotic cream if needed to prevent infection
• Taking an antihistamine for itching
• Seeing a doctor if pain worsens or other concerning symptoms arise

Most mild spider bites resolve on their own within a few days up to a week. Avoid scratching as this can cause infection. Consult a doctor if the wound shows signs of infection like increased swelling/redness, skin lesions, oozing pus, streaking redness, fever or flu-like illness.

Spider Bite Identification Tips

It can be challenging to identify the spider responsible for a bite without actually witnessing the event or capturing the spider. Here are some tips that may aid identification:

• Know venomous species found in your geographic area
• Compare bite marks and symptoms to reference photos online
• Note circumstances like if indoors vs outdoors, hiding place (woodpile, corner of home, etc)
• Examine spider's web design if present
• Note body shape and markings
• Observe eye arrangement and count
• Have an expert such as an entomologist analyze the remains of crushed spider

Spider bite treatment focuses on symptom management, not necessarily identifying the exact species. However, knowing the type of spider may guide expectations on symptoms and recovery time. Capture the spider safely after a bite if this can be done without endangering yourself.

When to Seek Medical Care for Spider Bites

Most spider bites do not require formal medical treatment. Home first aid of cleaning, ice, elevation, and over-the-counter analgesics is adequate for minor reactions. However, consult a doctor promptly if you experience:

• Diffuse rash or spotty rash spreading from bite
• Dizziness, blurred vision, difficulty breathing
• Excessive swelling, redness, pain
• Fever, chills, or headache
• Muscle cramps, involuntary contractions
• Nausea, vomiting, stomach or joint pain
• Oozing, ulceration, dark discoloration around bite
• Suspected bite from venomous spider like black widow

Children, older adults, pregnant women, and those with chronic health conditions may also want to see a doctor to assess spider bite severity. Most bites cause mild effects easily treatable at home. But the venom of some dangerous spider species requires prompt medical intervention.

Preventing Spider Bites

Many spider bites are defensive actions when a spider feels threatened or trapped against bare skin. Follow these proactive spider bite prevention measures:

• Reduce clutter in living spaces where spiders may nest
• Wear gloves, long sleeves and pants when working in crawl spaces, basements, attics
• Check bedding, linens, shoes, clothing before use
• Install window/door screens and seal cracks in the home's exterior
• Vacuum and sweep regularly to remove webs
• Apply pesticides if needed in heavily infested areas
• Use caution when reaching into unseen spaces where spiders may reside

Practicing good hygiene and being observant in areas where spiders live can help decrease the chances of inadvertent bites. Some spider bites may still occur despite best efforts. Knowing proper first aid and when to seek medical care allows for the best outcome when dealing with spider bites.
