American House Spider (Parasteatoda tepidaiorum)
The American house spider (Parasteatoda tepidariorum) is one of the most common spider species found in homes and commercial structures on Long Island, New York. Known for their small size and messy cobwebs, these spiders are often found in dark corners, basements, and garages. Although their appearance may be unsettling, American house spiders are generally harmless to humans.
American House Spider Quick Facts
Adult size: 4-8 mm long.
Color: Light to dark brown with various markings on the abdomen.
Diet: Carnivorous; feeds on insects and other small arthropods.
Behavior: Builds messy cobwebs in undisturbed areas; generally reclusive.
Lifespan: Typically, 1-2 years.
American House Spider Habits & Habitat
American house spiders prefer to live in dark, undisturbed areas where they can build their webs and catch prey. They are commonly found in basements, attics, garages, and in the corners of rooms or ceilings. Their cobwebs are often irregular in shape and can accumulate dust, making them easy to spot.
These spiders are generally reclusive and do not actively seek out human interaction. They are beneficial in that they help control indoor pest populations by feeding on insects, such as flies and ants. Despite their benefits, their webs and presence can be a nuisance, particularly if they are found in large numbers.
American House Spider Threats
American house spiders are not considered dangerous to humans. While they are capable of biting, their venom is not harmful, and bites are rare since they prefer to avoid contact with humans. The primary concern with these spiders is their webs, which can accumulate quickly and create a cluttered appearance in homes and buildings.
American House Spider Prevention
- Keep your home clean by regularly dusting and vacuuming to remove cobwebs and prevent spider infestations.
- Seal cracks, gaps, and openings around doors, windows, and the foundation to prevent spiders from entering your home.
- Reduce clutter in storage areas, such as basements and attics, to eliminate potential hiding places for spiders.
- Make sure window screens and door sweeps are tight and sealed to reduce entry points.
Cellar Spider(Pholcus phalangioides)
The cellar spider (Pholcus phalangioides), also known as the daddy long-legs spider, is another common spider species found indoors on Long Island. Known for their long, thin legs and small body, cellar spiders are often found in dark, damp areas such as basements, crawl spaces, and storage rooms. They are not harmful to humans and can help control insect populations indoors.
Cellar Spider Quick Facts
Adult size: Body length 6-10 mm, with legs up to 50 mm long.
Color: Pale yellow to light brown.
Diet: Carnivorous; feeds on insects and other spiders.
Behavior: Builds loose, tangled webs; prefers dark, damp areas.
Lifespan: Typically, 1-2 years.
Cellar Spider Habits & Habitat
Cellar spiders prefer dark, damp environments, making basements, crawl spaces, and closets ideal habitats. They build loose, tangled webs in corners and other undisturbed areas, where they wait for prey to become ensnared. Unlike some other spiders, cellar spiders do not regularly clean or repair their webs, which can lead to an accumulation of old, dusty webs.
Cellar spiders are known to vibrate their webs when disturbed, a behavior thought to confuse predators. They are also known to prey on other spiders, including those considered more dangerous, making them a somewhat beneficial presence in homes. However, their webs can be unsightly, especially if left undisturbed for long periods.
Cellar Spider Threats
Cellar Spider Prevention
- Reduce moisture levels in basements, crawl spaces, and other areas by using dehumidifiers or ensuring proper ventilation.
- Regularly clean and vacuum to remove webs and prevent spider infestations.
- Seal any cracks, gaps, or openings around doors, windows, and the foundation to prevent spiders from entering your home.
- Reduce clutter in storage areas to eliminate potential hiding places for cellar spiders.
- Use tight-fitting window screens and door sweeps to minimize entry points.
