Spider Control in NYC — Remove Webs, Nests, and the Spiders Themselves
Most spiders in New York City apartments and homes are nuisance pests — house spiders, cellar spiders (the long-legged "daddy longlegs" variety), and jumping spiders are all harmless to humans and actually beneficial because they prey on other insects. But that doesn't mean you have to live with them, and a significant spider presence is often an indicator that other insects they're feeding on are present in the structure. The exception to "nuisance pest" status: northern black widow spiders are found in NYC, particularly in undisturbed basement and garage areas, and their bite is medically significant.

About Spider Control in NYC
Spider control is fundamentally about two things: reducing the insect prey population that's feeding the spiders, and eliminating the harborage areas where spiders build webs and lay egg sacs. Spiders don't respond to bait products — they have to walk through or contact residual insecticide directly. Treatment focuses on crack-and-crevice applications in basement areas, along window frames and door frames, in attic spaces, and in storage areas where spiders concentrate. Cobweb removal is part of every treatment — undisturbed cobwebs attract more spiders to the same location.
In NYC multi-unit buildings, spiders often enter from exterior landscaping, through window screens, and via the same structural gaps that allow other pests in. Caulking gaps around window frames, door frames, and utility penetrations reduces spider entry significantly. Exterior perimeter treatment targeting foundation entry points is part of our standard spider control service.
Signs of Infestation
- ⚠Multiple active cobwebs, particularly in undisturbed corners, basement areas, window frames, and storage spaces
- ⚠Egg sacs (silky white or papery sacs) attached to webs or in protected corners — each sac can contain 100–400 eggs
- ⚠Spider sightings concentrated in one area — indicates a population, not just a wandering individual
- ⚠Black, glossy, button-shaped spider with red hourglass marking — black widow (medically significant, treat immediately)
- ⚠Brown spider with violin-shaped marking on head — brown recluse (rare in NYC but confirm before assuming)
- ⚠Large numbers of other insects present — spiders follow their food source

Our Treatment Approach
Spider treatment includes complete manual cobweb removal throughout the treatment area, followed by residual insecticide application via crack-and-crevice technique in all concentrated areas: basement perimeter, window frames, door frames, utility entry points, and attic spaces if accessible. Exterior perimeter treatment targets foundation areas, eaves, and exterior light fixtures (which attract the flying insects that feed spiders). Glue board monitoring is placed in basement and garage areas to track population. For black widow infestations, treatment is prioritized with direct contact application and confirmed elimination at the follow-up visit.
Which Spiders in NYC Are Actually Dangerous?
Most spiders found in NYC apartments — cellar spiders, common house spiders, sac spiders — are harmless and primarily a nuisance. However, black widow spiders have been documented in New York, particularly in basements and undisturbed storage areas, and their bite requires medical attention. If you're seeing unusual spiders with a red hourglass marking or an aggressive posture, call a professional rather than attempting removal.
Why Spiders Come Indoors in Fall and How to Stop Them
As outdoor temperatures drop in September and October, spiders seek warm harborage inside buildings — gaps around windows, unsealed utility penetrations, and weep holes in brick are common entry points in NYC buildings. A perimeter treatment in late summer combined with web removal disrupts established harborage before the fall migration begins. Inside, treating high-traffic corners, basement ceilings, and storage areas eliminates the prey insects spiders follow indoors.
Why Spiders Mean You Have Another Pest Problem
Spiders don't enter homes for food storage or warmth alone — they follow prey. A significant spider population indoors almost always indicates an underlying infestation of flies, roaches, gnats, or other insects that are sustaining them. Our inspection process identifies both the spiders and their food source, so treatment addresses the root cause rather than just the visible symptom.
Frequently Asked Questions
Do I have a black widow? Should I be worried?▾
Northern black widows are present in NYC, particularly in undisturbed garage, basement, and woodpile areas. Identifying features: shiny black body about 1/2 inch long, red hourglass pattern on the underside of the abdomen. If you suspect a black widow, don't handle it — contact us for a same-day or next-day inspection. Black widow bites are medically significant and require treatment, though fatalities are extremely rare in healthy adults.
Why do I keep getting spiders no matter how many I kill?▾
Because you're addressing the symptom, not the cause. Spiders are following their food supply — if your home has a consistent spider population, you likely have a consistent population of smaller insects they're feeding on. Treating the broader pest population and sealing structural entry points is more effective than targeting spiders directly.
Are daddy longlegs spiders poisonous?▾
No — the myth that cellar spiders (daddy longlegs) are extremely venomous but can't bite humans is false on both counts. They're minimally venomous and their venom has no significant effect on humans. They're entirely harmless nuisance pests.
How long does spider treatment last?▾
Residual treatments remain active for 60–90 days in interior crack-and-crevice applications. Exterior perimeter treatments can degrade faster due to weather exposure. We recommend seasonal re-treatment (spring and fall) for ongoing prevention.
How much does spider control cost in NYC?▾
Spider control starts at $350–$550 for a standard apartment or single-family home. We provide a written estimate before starting. The initial treatment includes cobweb removal and the follow-up inspection.
