Spider Bite Symptoms, Treatment & Venomous Species in New York

Spider Bites in New York: What You Need to Know

New York is home to several species of spiders that occasionally bite humans. While most spider bites are harmless, some can cause mild to severe reactions. Knowing how to identify venomous spiders, prevent bites, and treat symptoms can help New York residents stay safe.

Venomous Spiders in New York

The main spiders in New York that are capable of biting humans include:

• Brown recluse spider
• Black widow spider
• Yellow sac spider
• Hobo spider

Of these spiders, the brown recluse and black widow are the only two spiders in New York that are considered dangerous. Their bites can cause severe reactions in some cases.

Brown Recluse Spiders

The brown recluse spider is usually between 6-20 mm (0.2-0.8 inches) in body length and has a trademark violin-shaped pattern on its back. They are not aggressive spiders but may bite if pressed against the skin accidentally, such as when getting dressed or rolling over in bed.

Brown recluse spiders build irregular webs in garages, basements, closets, and sheds. In New York, they are most common in the western and central parts of the state.

The bite of a brown recluse spider can cause mild to severe symptoms depending on the amount of venom injected. Most bites cause mild reactions like itching, redness, and swelling. In rare cases, the bite site can develop into an ulcerous sore that takes weeks or months to heal.

Seek immediate medical care if you suspect a brown recluse spider bite. Though rare, severe reactions can cause fever, chills, nausea, and a systemic reaction throughout the body.

Black Widow Spiders

The black widow spider has a distinctive spherical abdomen with a red hourglass marking on the underside. Adult female black widows are around 1.5 cm (0.6 inches) in body length, while males are much smaller. They build tangled, web-like nests in protected areas like woodpiles, debris, and the exterior of buildings.

In New York, the northern black widow is found across the state while the southern black widow resides in the southeastern region. Black widows are not aggressive unless protecting an egg sac and most bites occur when humans come into direct contact with the spider.

Black widow bites can cause moderate to severe pain, as well as swelling and redness at the bite site. Other symptoms may include nausea, vomiting, headache, and muscle aches. Though extremely rare, severe envenomation can result in coma, respiratory failure, and death without medical treatment.

If bitten by a black widow, clean the bite area and ice it to reduce swelling. Safe home treatment is often possible for mild to moderate reactions but medical evaluation is still recommended. Seek emergency care if you experience severe pain, swelling, or systemic reaction after a suspected black widow bite.

Yellow Sac Spiders

Yellow sac spiders have pale yellow bodies around 0.5 cm (0.2 inches) long. They get their name from the yellow sac-like nests they construct in corners, crevices,ledges, or vegetation. Yellow sac spiders enjoy habitats indoors and outdoors, including sheds, garages, basements, gardens, and lawns.

The venom of a yellow sac spider is mild but may cause a stinging sensation, redness, itching, and swelling around the bite site. The reaction is rarely medically significant but can be painful. The elderly and young children may experience stronger reactions than healthy adults.

The bite of a yellow sac spider can be treated safely at home in most cases. Apply antiseptic cream, ice the area, and take OTC painkillers as needed for relief. See a doctor if you experience spreading redness, swelling, or ulceration around the bite.

Hobo Spider

The hobo spider resembles other common house spiders but has distinctive markings on its abdomen. Adults are around 1.5-2 cm (0.6-0.8 inches) in body length. Hobo spiders construct funnel-shaped webs in dark, moist areas like crawlspaces, basements, sheds, and woodpiles.

The venom of the hobo spider was once thought capable of causing severe skin injuries. However, newer research disproves this and shows the bites are not seriously harmful to humans. Some bites may result in mild itching, redness, and localized pain lasting up to 48 hours.

Apply antiseptic and bandage the bite site if bitten by a hobo spider. Taking OTC painkillers and using ice can help relieve symptoms. Seek medical care if you experience expanding redness, swelling, or have other concerning symptoms.

Preventing Spider Bites

You can take various precautions to avoid spider bites when living in or visiting New York:

• Wear gloves, long sleeves, pants, and closed-toe shoes when cleaning garages and basements.
• Clear clutter and debris from around the home where spiders may nest.
• Inspect or shake out clothes, shoes, towels, and linens before use.
• Install screens on windows and doors and seal cracks and crevices.
• Use insecticides or repellants labeled for spiders and their nests.
• Avoid putting limbs or appendages into areas you cannot see clearly.
• Be vigilant and look before grabbing or stepping as you enter sheds, garages, etc.

Teaching children about safe behavior around spiders can also help prevent bites. Supervise young children closely outdoors where spiders may inhabit play areas.

Spider Bite Symptoms

The symptoms caused by a spider bite depend on the type of spider, toxicity of the venom, and amount injected. Here are some common signs and symptoms:

• Immediate pain, swelling, redness at the bite site
• Itching, tingling sensation
• Small puncture marks or raised bump
• Muscle cramps, spasms near bite area
• Headache, fever, chills, nausea, vomiting
• Skin ulcers, blue-black lesion (brown recluse bite)

In severe reactions to venomous spiders, symptoms may progress to abdominal pain, difficulty breathing, chest pain, seizures, and loss of consciousness. Seek emergency medical care if you experience any severe or worsening reaction after a known or suspected spider bite.

Treating Spider Bites

Most mild spider bites can be treated at home using the following methods:

• Clean bite area with soap and water.
• Apply cold compress or ice wrapped in cloth to reduce swelling and pain.
• Keep bite area elevated above the heart if possible.
• Take OTC pain medication like acetaminophen, ibuprofen, or naproxen.
• Avoid scratching or irritating the bite since it can lead to infection.
• Watch for signs of infection like increasing redness/swelling, red streaks, pus, fever.

See a doctor for any of the following situations:

• Severe pain and swelling at the bite site
• Blistering or ulceration of the skin
• Difficulty breathing or swallowing
• Prolonged muscle cramps or spasms
• Fever, chills, sweating, nausea
• Red streaking leading from the bite area

People with weakened immune systems and those showing anaphylactic symptoms after a bite also need urgent medical care. Treatment may include antibiotics, steroids, antihistamines, antivenom, or other therapies as needed.

Professional Spider Removal

Eliminating food sources and hiding spots for spiders is the best prevention. But if you have an infestation of venomous spiders like black widows or brown recluses, consider professional pest control.

Spider exterminators have the tools and expertise to:

• Inspect your property and identify problem areas
• Safely remove spider egg sacs and nests
• Apply targeted insecticides to destroy the spiders
• Seal entry points so spiders cannot re-enter
• Offer advice to make your home less inviting to spiders

Professional control is especially helpful if spider bites have occurred frequently on your property or you have a widespread infestation inside or outside the home.

Choosing a Pest Control Company in New York

When hiring a pest control company, find one that:

• Is licensed and experienced with spider removal
• Performs thorough inspections to identify nests
• Uses the least toxic spider treatment methods when possible
• Explains their plan, products, and costs upfront
• Provides effective, long-lasting spider control
• Has good reviews and satisfied customers

Avoid companies that use scare tactics or pressure you to sign an expensive ongoing contract for regular service. A qualified exterminator should be able to eliminate your spider problem with one or two targeted treatments.

Protecting Your Home from Spiders

You can make your home less inviting to spiders by taking these steps:

• Install tight-fitting screens on windows and doors.
• Seal cracks and openings throughout the home.
• Reduce clutter like piles of debris, wood, and rocks near the foundation.
• Keep tree branches and shrubs trimmed back from the house.
• Move woodpiles and compost bins far from your home’s exterior.
• Clean gutters and direct drainage away from your home’s perimeter.
• Use lighting at entrances to discourage spiders that avoid bright areas.

Inside your home, regularly vacuum and dust to remove webs and food sources like insects. Store items like clothes, linens, and shoes inside plastic bins rather than cardboard boxes. Eliminate moisture sources like leaks and standing water as much as possible.

Spider-Proofing Your Home’s Exterior

Focus on sealing these key exterior entry points to keep spiders out:

• Openings where cables, wires, pipes, and vents enter your home
• Gaps where siding, rooflines, decks meet the structure
• Cracks in foundations, walls, ceilings
• Spaces around exhaust vents, attic vents, and lights
• Holes in window and door screens

Caulk, seal foam, copper mesh, and weather stripping can be used to plug exterior holes and gaps. Make sure crawl space vents are properly screened as well. Keep vegetation, debris, and mulch at least 2 feet away from your home's perimeter.

Keeping Spiders Out of Your Home

To prevent indoor spider infestations:

• Install door sweeps, thresholds, and screens on windows/vents.
• Seal cracks and openings in floors, walls, and ceilings.
• Eliminate moisture sources by fixing leaky pipes, condensation issues, etc.
• Clean kitchens thoroughly and store food in sealed containers.
• Vacuum and sweep away webs frequently.
• Remove stacks of materials like newspapers, magazines, and cardboard.
• Use dehumidifiers to keep humidity levels below 50%.

Diatomaceous earth sprinkled in entry areas can also deter crawling insects that spiders feed on. Be sure to properly identify and control any spider infestations rather than just removing individual spiders as they appear.
