Wolf Spiders in New York: Behavior, Bites, and Control

Wolf Spiders in New York: What You Need to Know

Wolf spiders are common throughout New York state, with several different species found across the region. While the thought of coming across a wolf spider may seem alarming, these spiders are generally not considered dangerous or aggressive towards humans. By learning more about their behavior, habitat, and life cycle, New Yorkers can coexist peacefully with these fascinating creatures.

Appearance and Identification

Wolf spiders are medium to large in size, with a legspan around 1-2 inches on average. They have a distinct appearance, with a brown, tan, grey, or black elongated body and legs. One of the most identifiable traits is their eyes - wolf spiders have large eyes arranged in three rows on the front of their cephalothorax (head region).

Some common wolf spider species found in New York include the Rabid Wolf Spider, Carolina Wolf Spider, and Tigrosa Wolf Spider. Each species has slight variations in markings, hair patterns, and coloring that can aid in telling them apart. For example, the Rabid Wolf Spider has chevron patterns on its abdomen, while the Tigrosa Wolf Spider has stripes and spots.

Habits and Behavior

Wolf spiders are unique among web-building spiders in that they do not spin traps to catch prey. Instead, they actively hunt and chase down their food source on foot. Their excellent eyesight gives them an advantage when seeking out small insects, their primary prey.

These spiders do not build permanent webs or nests. Female wolf spiders carry their egg sacs with them, attached to their spinnerets until the spiderlings hatch. Once hatched, the young spiders will climb onto their mother's back and ride around with her for a week or two before dispersing.

Wolf spiders exhibit interesting courtship behaviors. When a male is interested in a female, he will approach her slowly and begin an elaborate ritual dance. This involves careful touches, vibrations, and movements to signal his intentions. If the female is receptive, mating will occur.

Habitat and Distribution

Wolf spiders can adapt to a wide range of habitats. They are common in grasslands, forests, deserts, mountains, and even suburban or urban areas. In New York, wolf spiders are found throughout the state in fields, meadows, woodlands, wetlands, and backyards.

These spiders spend much of their time on the ground surface hunting and foraging. But they will also climb trees, hide under bark or rocks, and burrow into leaf litter or underground burrows. Some species prefer specific micro-habitat conditions - for example, the Carolina Wolf Spider lives in sandy soil habitats.

Threats and Prevention

Wolf spiders play an important role in controlling insect pest populations. And despite their imposing size and speed, they do not pose a major threat to people, pets, or property. Wolf spider bites are extremely rare and typically cause only mild reactions.

Like all spiders, wolf spiders will only bite if carelessly handled, injured/trapped against skin, or defending their egg sacs. Their venom is not considered medically significant, about the same as a bee sting for most individuals.

To prevent surprise encounters, keep woodpiles, rock walls, and other prime spider habitat well away from the home. Check shoes, gloves, and clothing when entering sheds or basements where spiders may hide. Use insect-proof screens on windows and doors.

Signs of Infestation

Seeing the occasional wolf spider in a field or basement corner is normal. But a large number concentrated inside the home may indicate an infestation. Signs to look for include:

• Multiple large spiders seen over a short time period
• Egg sacs or spiderlings present
• Webbing in corners or crawl spaces
• Insect prey such as crickets or flies caught in webs
• Spider droppings that resemble small black specks

An infestation may be the result of prey insects around the home, access to interior living spaces, insufficient sealing, or movement indoors during cold weather.targeted exclusion and sealing any cracks or gaps can help block their entry points.

Control and Removal

Wolf spiders are rarely an indoor pest requiring extensive control. But if they do become problematic, there are some effective and safe ways to reduce their numbers or remove them from the home:

• Remove and reduce clutter such as piles of wood, rocks, debris, or other items that can become harborage sites.
• Install weather stripping around doors and door sweeps to block access.
• Use screens on windows, vents, and floor drains.
• Apply insecticides or repellents such as diatomaceous earth in problem areas - follow label directions closely.
• Remove individual spiders through gentle sweeping or vacuuming.
• Use glue boards or spider traps for monitoring and removal.
• Trim plants, bushes, and vegetation touching the home's exterior.

In most cases, wolf spider invasions will be temporary and they will retreat to outdoor habitats after some exclusion and sanitation. But a recurring infestation may require help from a professional pest control expert who can assess the situation, identify entry points, and apply targeted treatments if necessary.

Wolf Spider Bites: Symptoms and Treatment

While wolf spiders are not aggressive and rarely bite people, some bites do occur if someone accidentally presses up against one or unintentionally threatens them. Their venom is not considered medically significant, but wolf spider bites can still be painful and cause mild reactions.

Signs of a Bite

Wolf spider bites typically feel like a pinprick or sting at first. Within 10-30 minutes, there is often pain and itching at the bite site along with:

• Redness
• Swelling
• Mild bruising or discoloration

Some people may also experience:

• Nausea
• Headache
• Dizziness
• Mild fever or chills

The bite area can remain irritated, tender, or itchy for up to a week as the venom runs its course. Severe reactions are very rare, but seek medical attention if bite symptoms seem abnormal or worsen rapidly.

First Aid and Treatment

Follow these steps for a suspected wolf spider bite:

1. Wash the area thoroughly with soap and water to reduce risk of infection
2. Apply a cold pack or compress to relieve swelling
3. Keep the bite elevated if possible
4. Take over-the-counter pain medication as needed for discomfort
5. Avoid scratching or irritating the bite to prevent infection
6. Monitor for signs of infection like increasing redness, pain, swelling, heat, or pus
7. See a doctor if symptoms do not improve within a few days

Allergic individuals may require prescription medication like antibiotics or epinephrine. But most wolf spider bites can be treated at home with rest and good wound care. The bite should completely heal within 1-2 weeks.

Prevention Tips

Use these preventive measures to avoid surprise wolf spider bites:

• Carefully inspect or shake out clothing, shoes, towels, and bedding before use
• Wear gloves and protective clothing when cleaning sheds, garages, basements
• Seal cracks, gaps, and openings throughout the home
• Install insect screens on windows and doors
• Keep the home free of clutter
• Get rid of insect and pest infestations

Being aware of your surroundings and wolf spider habits can help avoid accidental bites. Leave them alone if spotted, and contact a professional if they become an indoor nuisance or bite risk.
