Large Spiders in New York: Identifying the Harmless from the Harmful
This article aims to provide New York residents with information about large spiders they might encounter, differentiating between harmless species and those that pose a potential threat. The primary focus is on identification, potential dangers, and appropriate actions to take when encountering these creatures.
Identifying Common Large Spiders in New York
Defining "Large"
Before diving into specific species, it's important to define what constitutes a "large spider" in the New York context. Generally, spiders with a body length (excluding legs) of over half an inch are considered large. Leg span can also be a defining factor, with anything over two inches drawing attention.
Common Species
-
Wolf Spiders (Lycosidae): These are among the most frequently observed large spiders in New York.
-
Appearance: Brown and hairy, often with distinctive eye arrangements. They don't build webs to catch prey but actively hunt.
-
Size: Can reach up to 1.5 inches in body length.
-
Habitat: Commonly found outdoors in gardens, lawns, and under debris. They may enter homes in search of food or shelter.
-
-
Fishing Spiders (Dolomedes): Found near water sources, these spiders are skilled hunters of aquatic insects and even small fish.
-
Appearance: Large and often patterned with brown, gray, or black markings. They can be quite intimidating in size.
-
Size: Can grow quite large, with leg spans exceeding 3 inches.
-
Habitat: Usually found near ponds, streams, and other bodies of water. They might occasionally wander into homes located near these areas.
-
-
Barn Funnel Weaver (Tegenaria domestica): While not native, this species is widespread and commonly found indoors.

Size: Body length around 0.5 inches, but leg span can reach 2 inches or more.
-
Habitat: Prefers dark, undisturbed areas such as basements, garages, and sheds.
-
-
Hobo Spider (Eratigena agrestis): Often confused with the Wolf Spider and Funnel Weaver, though it is not common in New York. It warrants inclusion due to its reputation.
-
Appearance: Brown in color with chevron patterns on the abdomen.
-
Size: Grows to about 1/2 to 3/4 inches in body length.
-
Habitat: Usually found outdoors in cracks and crevices, but can enter homes seeking shelter.

Are Large Spiders in New York Harmful?
Understanding Venom
It's crucial to remember that while many spiders possess venom, very few have venom that poses a significant threat to humans. Most spiders in New York are primarily nuisance pests.
Harmless Species
-
Wolf Spiders: Bites from wolf spiders are rare and usually occur only when they are threatened. The bite may be painful, similar to a bee sting, and can cause localized swelling and redness. However, their venom is not medically significant to humans.
-
Fishing Spiders: Like wolf spiders, fishing spiders are not aggressive and will only bite if provoked. Their bites are also painful but pose no serious medical threat.
-
Barn Funnel Weavers: Bites are rare, and the venom is not considered dangerous to humans. Symptoms are usually mild and localized.
Potentially Harmful Species (and Why They're Rare)
- Hobo Spider: While the Hobo Spider has a reputation for necrotic bites, recent research has questioned the severity of their venom's effects on humans. Moreover, their presence in New York is minimal. If bitten, seek medical advice, but panic is unwarranted.
Medical Attention: When to Seek It
While most spider bites in New York are harmless, it's advisable to seek medical attention if:
- You experience severe pain, swelling, or blistering at the bite site.
- You develop systemic symptoms such as fever, chills, nausea, or difficulty breathing.
- You suspect you've been bitten by a potentially dangerous spider (though very rare in NY).
- You have underlying health conditions or a compromised immune system.
What to Do If You Encounter a Large Spider
Remaining Calm
The most important thing is to remain calm. Spiders are generally more afraid of you than you are of them. Avoid sudden movements that might startle the spider.
Safe Removal
- Gentle Guidance: Gently guide the spider into a container (like a jar) using a piece of cardboard.
- Relocation: Release the spider outdoors, away from your home.
- Vacuuming (If Necessary): If you can't capture the spider, vacuuming it up is an option, but be aware this may not kill the spider instantly.
Preventing Spider Infestations
- Seal Entry Points: Seal cracks and crevices in your home's foundation, walls, and around pipes.
- Remove Clutter: Eliminate clutter in basements, garages, and attics to reduce hiding places for spiders.
- Maintain Landscaping: Keep bushes and shrubs trimmed away from your house to prevent spiders from using them as bridges into your home.
- Professional Pest Control: If you have a recurring spider problem, consider contacting a professional pest control service.
