If you’ve seen ants in your home, your first instinct is probably to grab a spray.
And sometimes, that seems to work… for a day or two.
Then they come back. Most people don’t call pest control when they see ants. They call
when they realize they’re not going away.
So the real question becomes: At what point do you stop spraying and start calling a
professional?
Quick Answer: When Should You Call Pest Control?
Call pest control immediately if ants and pests keep returning after cleaning or spraying,
appear in multiple areas of your home, or show up consistently over several days.
At that point, the issue is no longer surface-level. You’re dealing with an active colony
and DIY methods won’t reach it.
The Line Between “A Few Ants” and an Infestation
Not every ant sighting means you have a major problem. But in NYC and Northern NJ
homes, ants rarely show up randomly.
Here’s how to tell the difference:
Occasional Ants (Usually Not a Major Issue)
● One or two ants near a sink or food source
● No consistent pattern day to day
● No visible trails
Active Infestation (Time to Take Action)
● Ants returning daily, even after cleaning
● Visible trails along baseboards, counters, or walls
● Activity in multiple rooms (kitchen, bathroom, living room)
● Ants appearing again after you’ve already sprayed
If you’re seeing these patterns, there’s a colony nearby and it’s growing.
Why Ants Keep Coming Back (Even After You Spray)
Most homeowners try to handle ants themselves first. The problem is, sprays only kill
the ants you see.
They do not:
● Reach the hidden nest
● Eliminate the queen
● Stop reproduction
In fact, spraying can actually make the problem worse. Some ant species, like odorous
house ants or carpenter ants, will split their colony when threatened—creating multiple
new problem areas instead of one.
👉 If you’ve already sprayed and the ants returned within a day or two, that’s a clear sign
the source hasn’t been addressed.
Signs It’s Time to Call Pest Control in NYC & NJ
If you’re experiencing any of the following, it’s time to bring in a professional:
● Ants return within 24–48 hours after DIY treatment
● You see consistent trails along walls, countertops, or baseboards
● Activity increases after rain or humidity (common in spring)
● Ants appear in multiple areas of the home (kitchen, bathroom, basement)
● The problem has lasted more than a few days without stopping
● You notice wood shavings or rustling sounds in walls (potential carpenter ants)
These are all signs of an active, established colony, not a temporary issue.
Other Pests to Watch for This May in NYC & NJ
Spring in the tri-state area doesn’t just bring ants. May is also prime time for:
● Spiders – Emerging from winter hiding spots, often near windows and
basements
● Mice & rats – Seeking food and water after heavy spring rains
● Cockroaches – Thriving in warm, humid conditions and shared building walls
● Stinging insects (wasps, bees) – Beginning to build nests in eaves and attics
Many of the same entry points and moisture issues that attract ants also invite these
pests. A professional inspection addresses the full picture.
What Professional Pest Control Does Differently
At Chelsea Pest Control, we don’t just treat what you see; we find where it’s coming
from.
Our ant control process includes:
● Identifying the exact ant species (different species require different treatments)
● Locating the nest or colony (often inside walls, under slabs, or in crawl spaces)
● Using targeted baiting to reach the queen and colony, not just worker ants
● Eliminating the queen to stop reproduction at the source
● Addressing entry points to prevent return after treatment
This is how the cycle actually gets stopped; not just paused.
What You Should Do Right Now (Before Calling)
If ants keep coming back:
● Avoid repeated spraying – It can scatter the colony and make treatment harder
● Clean up food and moisture sources – Wipe counters, fix leaks, store food in
sealed containers
● Take note of where you’re seeing activity – Photos and locations help the
technician
● Don’t seal entry points yet – You may trap the colony inside your walls
Don’t Wait Until It Gets Worse
In May and early summer, ant colonies grow quickly. Queens lay hundreds of eggs, and
what starts as a small issue can spread into multiple areas of your home within weeks.
Delaying professional treatment can turn a $300 problem into a $1,000+ one, especially
if carpenter ants are involved (they cause structural damage).
If ants aren’t going away, it’s time to address the source; not just the surface.
