What I Walked Into

July is usually when wasp calls start becoming more common around Port Moody & Metro Vancouver. Warm weather, outdoor eating, garbage areas, decks and sheltered exterior spaces can all create the right conditions for wasps to become active.

This recent job was at a home in Port Moody where the homeowner noticed wasps flying around the back deck. At first, they thought the wasps were just passing through, but within a few days, the activity became more frequent.

When I arrived, the homeowner showed me the area where the wasps were gathering. They were most active near the deck edge and around a small opening close to the exterior siding.

That is usually when I slow down and watch the flight pattern. With wasps, the key is not just seeing where they are flying. It is finding where they are entering, where they are gathering and whether there is a nest or active entry point nearby.

After watching the activity for a few minutes, I could see the wasps returning to the same spot again and again. That told me there was likely an active nest or nesting area connected to that opening.

The Problem

The main issue was that the wasps had chosen a sheltered area close to where the family spent time outside.

That made the problem more stressful because the deck was a high-use area. The homeowner had kids, pets and visitors using that space, so leaving the wasps alone was not a comfortable option.

Wasps can become defensive when their nest is disturbed, especially when the activity is close to doors, decks, patios, sheds or outdoor seating areas. Even if the nest is not fully visible, repeated wasp traffic in one spot is usually a strong sign that something is happening behind the surface.

In this case, the wasps were using a small exterior opening. The homeowner had only noticed the flying activity, but the real concern was the hidden nesting area behind it.

That is why I always tell homeowners not to block the opening or spray randomly without knowing where the activity is coming from. If the wasps are active inside a wall void or hidden space, disturbing them the wrong way can make the situation worse.

The Process

I started by inspecting the exterior area and watching the wasp movement closely.

The flight pattern showed that the wasps were returning to the same access point, so I focused the treatment around the active entry area and the surrounding space.

Before treating, I explained to the homeowner what I was seeing and what to expect after the service. With wasp treatments, it is normal to see some activity for a short time as wasps return to the treated area.

Once the treatment was completed, I advised the homeowner to avoid the area for a while and to keep kids and pets away from that side of the deck until the activity had reduced.

I also checked nearby spots where wasps may try to build again, including the eaves, deck edges, fence line, shed area and other sheltered exterior spaces.

The Outcome

After the service, the activity began to slow down.

The homeowner noticed fewer wasps around the deck, and the space started to feel more usable again. That is always the goal with wasp control — not just treating the nest, but helping the homeowner feel safe and comfortable using their outdoor space.

I also gave them a few things to watch for over the next couple of days. If wasps continue entering the same spot heavily after treatment, it may need a follow-up check. But in this case, the activity reduced as expected.

The homeowner was relieved because they finally understood where the wasps were coming from and why they had become so active near the deck.

DIY Advice

Here are a few wasp prevention tips I shared with the homeowner:

Keep outdoor food and drinks covered when eating outside.

Make sure garbage and recycling bins are closed tightly.

Rinse sticky containers before putting them in outdoor bins.

Check eaves, sheds, deck edges and fence lines for early nest activity.

Avoid swatting at wasps, as this can make them more defensive.

Do not block a wasp entry point if wasps are actively going in and out.

Keep kids and pets away from areas with repeated wasp traffic.

Call a professional if wasps are active near doors, decks, patios or walkways.

Small prevention steps can help, but once wasps have an active nest near a high-use area, it is usually safer to have it inspected properly.

Professional Insight

Wasp problems around Port Moody & Metro Vancouver are often connected to sheltered exterior spaces. Decks, sheds, eaves, wall gaps, rooflines, fences and outdoor storage areas can all provide places for wasps to build or hide.

The most important thing is to watch the flight pattern. If wasps are coming and going from the same spot, there is usually a reason.

That reason might be a visible nest, a hidden nest or an entry point leading into a protected space.

Professional wasp control focuses on finding that activity source and treating it safely. It is not just about spraying the wasps you see flying around. It is about understanding where they are returning and why that area is active.

Closing Thoughts

This job was a good reminder that wasps can become a problem quickly when they settle near the spaces people use every day.

If you are seeing wasps around your deck, patio, shed, roofline, fence or doorway, do not wait until the activity gets worse. Wasp issues are usually easier and safer to handle when they are caught early.
