Which Ant Are You Dealing With?

Short answer: Big black ants, a quarter inch or more, especially at night and especially near a window, door, or roofline that has ever leaked, are carpenter ants and they deserve attention. Small ants trailing along a counter or patio edge are a nuisance problem: annoying, but not structural.

The distinction changes everything about the plan, which is why we will not quote an ant job over the phone without at least a photo. Treating a carpenter ant problem as a trail-and-bait nuisance job leaves the nest and the wet wood exactly where they were.

Carpenter Ants Are Really a Moisture Story

Carpenter ants do not eat wood; they excavate it to make galleries, and they strongly prefer wood that is already softened by moisture. That single fact is why a carpenter ant call is worth taking seriously, and why treating the ants alone is only ever half the job.

The nest sites we find most often in South Jersey homes tell the same story every time: a sill plate under a long-term window leak, a rim joist behind a failed gutter, fascia and roof sheathing under an ice-dam or flashing leak, a porch column standing in water, and the wall below a bathroom or kitchen that has been weeping quietly for years. Wherever the ants are, water got there first.

This is the same diagnostic we run for crawl space wildlife and for every exclusion job: the animal or the insect is the symptom, and the building condition is the problem. We would rather tell you about the leak than sell you an annual contract that treats the ants over and over.

How Acorn Handles an Ant Problem

Identify the Species

First, because everything downstream depends on it. Carpenter ant, nuisance ant, and the occasional termite mistaken for an ant all get sorted at the inspection. Termites are not our work, and if that is what you have we will tell you plainly and point you to a termite contractor.

Find the Nest, Not Just the Trail

Ants you see are foragers, and they may be a long way from the nest. We trace trails back, check the moisture-damaged wood, and use the sawdust and swarmer evidence to work out whether the nest is inside the structure or outside in a tree or stump with the house as a feeding ground. The answer changes the treatment entirely.

Treat the Colony

Treatment is directed at the colony and the galleries rather than sprayed along the visible trail, because killing foragers does nothing to a nest that keeps producing them.

Fix the Wood and Seal the Way In

This is the half that lasts and the half we are actually specialists in. Damaged wood gets identified, the moisture source gets called out, and the entry points get sealed: gaps at the sill, utility penetrations, failed caulk lines, and the roofline and soffit gaps we already close for wildlife exclusion. Repairs carry the Seal-Tight Warranty.

The Honest Notes

We are not a general pest control company and do not sell quarterly spray programs, so if what you want is a recurring contract we are the wrong call. What we do is find the nest, deal with it, and fix the conditions that produced it. We also do not treat termites, bed bugs, or cockroaches, and we will say so on the phone rather than at your kitchen table.
