New York’s Ant Problem Peaks in June. Here’s How to Keep Them Out for Good

June is when ant colonies hit full stride across New York. The weather is warm, the soil is soft, and queens that overwintered underground are pushing workers out in huge numbers to find food, water, and new nesting sites. If you noticed a single ant on the counter in May and a steady trail by mid-June, that timing is not a coincidence.

For homeowners in Long Island, Queens, Brooklyn, and Westchester County, this is when a small ant problem turns into a full kitchen invasion. A few targeted moves can break the cycle before the colony decides your pantry is the new headquarters.

Why June Is Peak Ant Season

Ants are cold-blooded, so their activity rises with the temperature. By early June, soil temperatures across Nassau County, Suffolk County, and the five boroughs hit the sweet spot for foraging and reproduction. Colonies that spent winter dormant are now hunting protein and sugar to feed brand new larvae. Your house, with its crumbs, leaky pipes, and steady indoor climate, looks like prime real estate.

The most common offenders we see this time of year:

• Pavement ants crawling out of sidewalk cracks and driveway seams
• Carpenter ants chewing through damp wood around windows, decks, and roof lines
• Odorous house ants trailing across counters (you will know them by the rotten coconut smell when crushed)
• Pharaoh ants in apartments and commercial buildings, especially in Manhattan and the Bronx

How to Keep Ants Out of Your Home

Most ant invasions start with a single scout. Stop the scout, and you usually stop the colony. A few habits go a long way:

• Wipe counters nightly and store sugar, honey, and pet food in sealed containers
• Take trash out before it sits overnight, especially in summer heat
• Caulk gaps around windows, doors, dryer vents, and pipe penetrations
• Trim shrubs and tree limbs that touch the house (ants use them as bridges)
• Fix slow leaks under sinks and around outdoor spigots

If you spot a trail, do not spray it on sight. That kills the visible workers but scatters the colony, which often makes the problem worse. Bait works better because foragers carry it back to the queen.

When to Call an Ant Exterminator

If trails keep coming back, you see winged ants indoors, or you hear faint rustling inside wall voids (a classic carpenter ant sign), it is time for a professional inspection. Our ant control service targets the colony, not just the workers you can see. The KO-12 Annual Program covers ants along with most common pests on a year-round schedule, so they stay down for the count.
