If you're concerned about using chemicals around children or pets, we cover low-toxicity options too.
The Problem
Ant infestations are not just a nuisance. In New York, the most destructive species is the carpenter ant, which tunnels through wood to create nests, potentially weakening structural beams over time. Unlike termites, they don't eat wood, but their excavations can still cause costly damage. According to the National Pest Management Association, carpenter ants are the most common wood-destroying pest in the Northeast. Meanwhile, fire ants—established on Long Island and spreading—deliver painful stings that can cause allergic reactions. Their colonies can contain 100,000–500,000 workers, making eradication challenging without professional help.
Warning Signs
- •Live ants indoors, especially in kitchens or bathrooms.
- •Trails of ants moving along baseboards, countertops, or outdoor pathways.
- •Small piles of wood shavings (frass) near baseboards or window sills—a sign of carpenter ants.
- •Rustling sounds inside walls, especially at night (carpenter ants are nocturnal).
- •Winged ants (swarmers) indoors in spring—often mistaken for termites.
- •Visible ant nests in soil, under mulch, or in wall voids.
- •Unexplained damage to wooden structures, like hollow-sounding beams.
Risks of Waiting
- ⚠Carpenter ant colonies can expand into multiple satellite nests, causing extensive structural damage.
- ⚠Fire ant stings can cause severe allergic reactions, including anaphylaxis in sensitive individuals.
- ⚠ants can contaminate food and surfaces, spreading bacteria like Salmonella.
- ⚠Delaying treatment allows colonies to grow, making elimination more expensive and time-consuming.

Treatment Options
Bait Stations
$15-$30 per station (DIY); $150-$250 for professional installationGel or granular baits placed along ant trails. Workers carry poison back to colony, killing the queen and brood.
Perimeter Spray & Dust
$200-$400 for standard homeProfessional-grade liquid sprays applied around foundation, windows, and doors, combined with dust in wall voids for carpenter ants.
Fumigation
$1,500-$4,000Tenting the entire structure and releasing gas to kill all ants inside. Rarely used for ants alone, but effective for severe, widespread infestations.
How to Identify the Ant Species in Your New York Home
Once you've identified the species, you can tailor your approach. For pavement ants, seal cracks and use bait stations along the foundation. For odorous house ants, eliminate moisture sources and use gel baits indoors. For carpenter ants, locate and treat the parent nest (often in a tree stump or damp wood) and any satellite nests in walls. Fire ants require mound treatments or broadcast baits. Remember: using the wrong product can scatter the colony and make things worse.
The Science Behind Ant Baits: Why They Work (and When They Don't)
Another common mistake is using too much bait. ants are sensitive to strong odors; a pea-sized dab is enough. Replace baits every few days to keep them fresh. Store baits away from children and pets, but note that modern baits are formulated in child-resistant stations. If you have a severe infestation, consider a professional baiting program that rotates formulas seasonally.
Carpenter ants vs. Termites: How to Tell the Difference in New York Homes
Both carpenter ants and termites cause wood damage, but they are very different pests. Carpenter ants excavate wood to create smooth tunnels for nesting, but they do not eat the wood. Termites eat the wood itself, leaving a honeycomb pattern. In New York, the most common wood-destroying insect is the carpenter ant, not the termite, because the climate is cooler. However, subterranean termites do exist, especially in the Hudson Valley and Long Island. How to tell them apart: Carpenter ant swarmers are black or dark red, have elbowed antennae, and their front wings are longer than their back wings. Termite swarmers are pale or dark brown, have straight, bead-like antennae, and both pairs of wings are equal length. Carpenter ants leave behind coarse, sawdust-like frass (wood shavings mixed with insect parts). Termite frass is more like tiny, six-sided pellets. If you tap on a hollow-sounding beam, carpenter ants may produce a rustling sound, while termites do not. If you suspect either, call a professional for an inspection. Misidentification can lead to the wrong treatment and further damage.
Ant Inspection: Four Evidence-Based Checks
A short visual guide to ant trails, carpenter-ant evidence, indoor food and moisture conditions, and exterior entry points.
Read the video transcript
Follow visible ant trails to likely entry gaps and photograph the route before cleaning or sealing. Coarse frass near wood can be evidence of carpenter-ant activity, but identification requires closer inspection. Reduce accessible food and moisture, and inspect plumbing and wall penetrations instead of relying only on surface spray. Check mulch, vegetation, siding clearances, and utility entries. Treatment scope should follow confirmed evidence.
Ant Control Options Comparison
| Method | Best For | Cost Range | Duration |
|---|---|---|---|
| DIY Baits | Small infestations of common ants | $10–$50 | 1–2 weeks |
| Perimeter Spray (Professional) | Moderate to heavy infestations | $200–$400 | 1–3 months |
| Carpenter Ant Treatment | Carpenter ants in wood | $300–$600 | 1 day + follow-up |
| Fire Ant Mound Treatment | Fire ants in lawns | $150–$300 | 1–2 weeks |
What Affects Cost
- ✓Ant species: Carpenter ant treatments cost more due to drilling and dusting.
- ✓Infestation size: Multiple colonies or large nests increase time and materials.
- ✓Home size and construction: Crawlspaces, slab foundations, or multi-story homes require more labor.
- ✓Accessibility: Nests in walls or attics may need drilling or opening walls.
- ✓Location: Urban areas like NYC have higher labor rates than upstate regions.
- ✓Service guarantee: Plans that include retreats cost more upfront but save money long-term.
- ✓Season: Spring and summer demand is higher, sometimes leading to premium pricing.

When to Call a Professional
Call a professional if you see carpenter ant frass, hear rustling in walls, find winged ants indoors, or have a large or recurring infestation that DIY baits haven't resolved. Also call if anyone in your household is allergic to ant stings, or if you own a restaurant or food business where ants pose a health code violation. inspection and quote terms vary by provider statewide—call +1 888 546 7983.
DIY vs Professional
DIY ant control works well for small, localized infestations of common household ants like pavement ants or odorous house ants. Over-the-counter baits and sprays can eliminate a colony if used correctly—place baits along trails, avoid sprays near baits, and keep surfaces clean. However, for carpenter ants, fire ants, or large multi-colony infestations, professional treatment is almost always necessary. Professionals have access to stronger insecticides, can locate hidden nests using moisture meters or borescopes, and provide a service guarantee. The average one-time professional treatment costs $150–$600, which often saves money compared to repeated failed DIY attempts.
Local Context
New York State's diverse geography and climate mean ant problems vary widely. In New York City and its suburbs, pavement ants and odorous house ants are the top complaints, thriving in the dense urban environment. Infestations often originate from cracks in sidewalks and building foundations. In upstate areas like the Adirondacks and Catskills, carpenter ants are predominant due to abundant forests and older wooden homes. Spring swarms of carpenter ants are common in April and May. On Long Island, red imported fire ants have become established since the 1990s, with active colonies reported in Nassau and Suffolk counties. Their mounds can be hidden in lawns and parks, posing a sting hazard to children and pets. Climate plays a role: wet springs and summers (like 2023's rainy season) drive ants indoors seeking dry shelter. Conversely, drought conditions can push ants to search for moisture inside homes. In Buffalo and Rochester, lake-effect snow and humidity contribute to moisture issues that attract carpenter ants. Across the state, the peak season is March through October, but indoor sightings can occur year-round if a nest is established in a heated structure. If you live in a region with known fire ants, be extra vigilant during warm months and consider professional mound treatments.
Species and regulation must be checked before treatment
An address alone cannot establish the ant species, nest location, or treatment. Around this property, follow trails, document entry points, and distinguish coarse carpenter-ant frass, soil mounds, and ordinary foraging before choosing a control method.
Carpenter-ant evidence boundary
University of Minnesota Extension notes that carpenter-ant parent nests are commonly associated with moist or decayed wood, while satellite nests may occur in drier voids. Correct moisture problems and identify the nest rather than treating every large ant as proof of structural damage.
