Mosquitoes: A Typical Service Visit in Ottawa

What I Walked Into

A common call we receive during Ottawa’s warmer months comes from homeowners who can no longer enjoy their backyard without being bothered by mosquitoes.

The activity is usually most noticeable around a deck, patio or shaded part of the yard. The homeowner may notice that mosquitoes become worse around dusk, particularly after rain or during warm, humid weather.

Before recommending service, I walk through the outdoor areas and look for the conditions that may be contributing to the problem.

The Problem

Mosquito problems do not always begin with a large pond or an obvious pool of water. Small amounts of standing water around a property may be enough to support breeding.

Common areas I check include:

Outdoor containers that collect rainwater

Clogged or poorly draining gutters

Uncovered rain barrels

Plant saucers and garden items

Low areas where water remains after rain

Dense, shaded vegetation

Protected spaces beneath decks or around patios

When several of these conditions are present, mosquito pressure may continue even when the homeowner regularly maintains the yard.

The Process

I begin by asking where and when mosquito activity is most noticeable. This helps narrow the inspection to the areas where people are being affected most often.

Next, I check accessible outdoor spaces for standing water, drainage concerns, shade and sheltered resting areas. I also look at how the yard is used, including seating areas, walkways and places where family members or guests spend time.

Based on the findings, I recommend a mosquito-control plan suited to the property. The goal is to address active areas while helping the homeowner reduce the conditions that support continued activity.

The Outcome

A professional mosquito service should also give the homeowner a clearer understanding of what is contributing to the problem.

After the visit, the homeowner knows which areas require ongoing attention, which outdoor items should be emptied after rain and where mosquito activity is most likely to develop.

Because mosquitoes can travel from neighbouring properties and surrounding areas, no outdoor service can prevent every mosquito from entering a yard. However, addressing activity areas and breeding conditions can help reduce mosquito pressure.

DIY Advice I Shared

Here are practical steps Ottawa homeowners can take:

Empty outdoor containers after rainfall

Keep gutters clear and draining properly

Cover rain barrels with secure screening

Refresh birdbath water regularly

Avoid leaving water in buckets or garden equipment

Maintain drainage around patios and foundations

Trim excessive vegetation around gathering areas

Repair damaged window and door screens

Wear suitable insect repellent when mosquitoes are active

Professional Insight

Mosquito activity usually involves more than one contributing condition. Removing one container of water may help, but other breeding or resting areas may remain elsewhere around the property.

Ottawa Public Health advises residents to remove standing water because mosquitoes require water to breed. Professional service works best when it is combined with consistent property maintenance and personal protection from bites.
