What I Walked Into

March is when I start getting the first real ant calls of the year in Ottawa. As soon as the snow starts melting and the ground softens, ants start moving.

A couple weeks ago, a homeowner reached out after noticing a steady line of small black ants along the kitchen counter. At first, they thought it was just a few scouts. By the next morning, there were dozens.

It was a townhouse in Ottawa, a fairly modern, clean home. The ants were mostly around the sink area and trailing toward a small crack near the back door. They had tried wiping them up and using a store-bought spray, but the ants kept coming back.

That’s usually how these jobs start.

The Problem

With ants, what you see is only a small part of the problem. The ones on the counter are just workers. The colony itself is usually hidden somewhere inside the walls, under flooring, or just outside along the foundation.

During my inspection, I followed the trail from the kitchen down to the basement area and then outside. Along the exterior foundation wall, there was a small gap where the concrete had shifted slightly over the winter. That’s likely where they were getting in.

Inside, I found more activity behind the dishwasher and under the sink cabinet. There were tiny entry points around the plumbing lines where the ants were traveling back and forth.

The homeowner was mostly worried about contamination. Ants crawling across food prep areas and into cupboards is stressful. Even if they aren’t dangerous species, nobody wants insects in their kitchen.

In Ottawa, March ant problems are common because the ground outside is still cold and wet. Homes offer warmth and easy access to food.

The Process

The first thing I did was confirm the species. That matters because treatment depends on the type of ant and where they’re nesting.

Next, I traced the full trail. I never just treat where the ants are visible. I follow their movement pattern to understand where the colony is likely located.

Inside the home, I applied targeted bait in specific areas where activity was highest. Bait works better than spraying in most ant situations because it allows worker ants to carry treatment back to the colony.

Outside, I treated the foundation area where they were entering. I sealed visible cracks and advised on closing small gaps around the back door threshold.

The key is not overdoing it. You don’t want to scatter ants or push them deeper into the structure. You want controlled elimination and proper entry point correction.

Everything was handled without disrupting their daily routine. No strong odors, no unnecessary mess.

The Outcome

Within a few days, the activity slowed down noticeably. The ant trail on the counter stopped completely. By the end of the week, there were no new sightings.

I checked back to make sure there was no fresh movement, especially around the sink and back door. Everything stayed quiet.

The homeowner told me the biggest relief was being able to leave food on the counter briefly without worrying about ants showing up. That constant checking and wiping had become stressful.

Once the ants were gone, the house felt normal again. No lines across the kitchen. No surprises when turning on the lights.

DIY Advice I Shared

Before I left, I gave them a few simple things to stay on top of. None of it is complicated, but consistency makes a difference with ants.

• Wipe down kitchen counters daily, especially near sinks. Ants are drawn to moisture as much as food, so even a damp cloth left overnight can attract them.

• Keep the sink dry before bed. Don’t leave standing water or dishes soaking overnight if possible.

• Avoid leaving sugary items, fruit, or crumbs out overnight. Even small amounts can draw a trail quickly.

• Store honey, syrup, sugar, and baking supplies in sealed containers instead of loosely closed packaging.

• Empty garbage regularly and make sure the lid closes tightly. Kitchen trash is a common target in early spring.

• Sweep or vacuum along baseboards where crumbs collect and often go unnoticed.

• Seal small cracks around doors and windows as soon as they’re noticed, especially near kitchens and patios.

• Watch for early scout ants in spring. If you see a few, don’t ignore it. A small trail now can turn into steady traffic within days.

They followed those steps, especially keeping the sink area dry at night and staying on top of food storage. That helped prevent the ants from coming back after treatment.

Professional Insight

Ant problems usually start small. Most people see a handful on the counter and assume it’s random. The problem is, by the time you’re seeing them regularly, they’ve already established a path between your home and the colony.

A single ant trail can mean hundreds or even thousands more nearby. The workers you see are just gathering food. The queen and the main nest are hidden somewhere safe — inside a wall, under flooring, or outside along the foundation.

Store sprays can kill the ants that are visible, and sometimes that gives temporary relief. But spraying often scatters them. When that happens, the colony can split or relocate, which makes the issue harder to control later.

In Ottawa, early spring is actually the best time to handle ants properly. Colonies are just becoming active, and addressing the nest early prevents bigger problems in late spring and summer when populations increase.

When I look at an ant job, I’m not focused on how many ants are on the counter. I’m focused on where they’re coming from and why they chose that spot in the first place. Once you fix that part, the rest usually follows.

Closing

March is usually when Ottawa homeowners start opening windows, cleaning up after winter, and getting ready for spring. It’s also when ants start exploring.

If you notice trails forming inside your home, it’s better to deal with it early rather than waiting for it to grow.

If you’re seeing something similar, feel free to reach out.
