Ant Extermination Cost on Long Island

Ant extermination cost on Long Island depends on the species, severity, and whether ongoing prevention is included. Here's a realistic breakdown.

One-Time Treatment

• Pavement ants or odorous house ants (single visit): low to mid three figures
• Carpenter ants (single visit): mid to high three figures, depending on colony locations
• Severe whole-home carpenter ant treatment: low four figures

Quarterly Prevention Plans

Quarterly perimeter programs cost less per visit and dramatically reduce re-invasion. Most Long Island homeowners on quarterly plans pay modest amounts per quarter and almost never see ants indoors.

What Affects the Price

• Species (carpenter ants are more expensive due to the difficulty of finding satellite colonies)
• Number of trails and entry points
• Home size
• Whether exterior treatment is included

Why Over-the-Counter Is False Economy

Spraying ants — especially odorous house ants — causes budding. The colony splits into multiple smaller colonies, multiplying the problem. Professional gel baits avoid this by killing the queen and entire colony.
