What I Walked Into

During the inspection, it became pretty clear this wasn’t a “one mouse” situation. The signs were spread out, and that usually means the activity has been going on for a bit.

Here’s what we found:

• Droppings behind the fridge and along the baseboard in that area. That spot stays warm, it’s close to food, and people rarely pull the fridge out, so rodents like it.

• Light gnaw marks on a few stored items in the basement. Nothing destroyed, but enough to show they were exploring and testing what they could chew.

• Nesting material tucked behind insulation near a utility line. It looked like bits of shredded paper/fabric type stuff — the kind of thing they drag in once they feel safe enough to settle.

The homeowner’s biggest stress wasn’t even the mess. It was the uncertainty. They didn’t know:

• how many rodents they were dealing with

• where they were coming in

• whether they were getting into food storage

• if they were chewing wiring somewhere out of sight

And once you hear noises at night or find droppings, it’s hard to relax in your own home. In this case they were especially worried about the kitchen, the pantry, and the basement storage — and whether it would keep getting worse.

In winter, it usually does if nothing changes. Rodents don’t head back outside once they’re comfortable. If they’ve found warmth and easy access, they tend to stay.

The Process

We started with a full inspection, inside and out. I don’t like guessing with rodents — the goal is to figure out how they’re getting in, where they’re active, and what they’re using for food/water.

Here’s what that inspection looked like:

• Exterior check: foundation line, siding edges, gaps near vents, and anywhere pipes/cables enter the home

• Doors and garage: looking at the bottom seal, side seals, and any light coming through

• Basement and utility areas: focusing on the spots where rodents commonly travel — along walls, behind storage, near sump/utility lines

• Kitchen: behind and under appliances, inside the pantry, and along baseboards

In this home, we found two main issues:

• a couple small gaps near where cables entered the house

• worn weather stripping on a side door that wasn’t sealing tight

After we confirmed activity and the likely routes they were using, we set up a targeted control plan. That means placing control points where they actually travel — not randomly and not just where it’s convenient. We focused on:

• the pathways (along walls and edges where droppings were showing up)

• the problem zones (kitchen area and basement/utility side)

• areas where we could monitor progress and adjust if needed

At the same time, we worked on exclusion — sealing up the main entry points we found so nothing new could keep coming in while we were dealing with what was already inside.

The Outcome

After everything was in place, the change was noticeable pretty quickly. The scratching noises at night stopped, and there were no new droppings showing up in the kitchen or basement. The areas we were watching stayed clean, which is always a good sign.

The homeowner followed up later and said the biggest difference was being able to relax again. They weren’t listening for sounds after dark or checking the floors every morning. They could use their kitchen and basement without worrying about what might be hiding nearby.

That’s usually how these jobs end when things are done properly. Once the rodents are gone and entry points are dealt with, the house settles back into feeling like a home instead of a problem that needs watching.

DIY Advice I Shared

Before I left, I gave them a few simple things to stay on top of:

• Store food and pet food in sealed containers

• Keep cardboard off basement floors

• Fix small leaks under sinks and near utility areas

• Check door seals and weather stripping once a season

• Keep clutter away from walls where rodents travel

They followed through on those steps, and it made a real difference in keeping the home stable after treatment.

Professional Insight

I’ll always be honest — some rodent issues can be slowed down with DIY work, but winter infestations usually need a professional eye. Rodents don’t just show up randomly. They find warmth, shelter, and entry points most homeowners never notice.

Having someone inspect properly can save a lot of time, stress, and repeated problems.

Closing Thoughts

Every rodent job reminds me how important it is to catch things early. February is cold, quiet, and busy for rodents — even if it doesn’t feel that way to us. If you’re in Southwestern Ontario and hearing noises, finding droppings, or just feeling unsure, it’s worth checking sooner rather than later.

You’re not overreacting. You’re just paying attention.
