Ticks in Toronto: The Real Risk

Toronto Public Health conducts annual tick surveillance and has confirmed established blacklegged tick populations in High Park, the Don Valley, and other ravine-adjacent areas. Lyme disease is a reportable illness in Ontario, and confirmed case numbers have increased steadily as tick populations expand across Southern Ontario.

The key insight for Toronto homeowners: ticks don't need a forest. They're found at the edge of any lawn that backs onto naturalized green space — including the thin strip of vegetation between a backyard fence and a ravine trail. If your property has any wooded edge, ravine view, or backs onto a park, seasonal tick treatment is a reasonable precaution.

Toronto Tick Season: When Is the Risk Highest?

Ticks don't disappear in winter — they go dormant and become active again whenever temperatures rise above 4°C. In Toronto's climate, that means tick pressure runs from the first spring thaw right through to late autumn — here is how the risk shifts across the season:

The May–July nymph window is the most dangerous period for Lyme disease transmission in Ontario. Nymphs are the size of a poppy seed — often found and removed only after they've been attached long enough to transmit Lyme disease. A late May treatment gets ahead of this window, and the monthly visits that follow keep the treated zones renewed through June and July while nymph activity is at its height.

What Should Children and Pets Do During a Tick Treatment?

This is the most common question we get from Toronto parents, and the answer starts with one simple rule: keep children and pets off the treated area until the spray has dried, as the product label directs.

The product we use is a synthetic pyrethroid — a class of insecticides modelled on natural compounds found in chrysanthemum flowers. Our licensed technician applies it according to its label directions, to vegetation (leaves, shrubs, fence lines, leaf litter) where ticks rest, rather than broadcasting it across open lawn where children and pets play.

At BuzzSkito, we also observe buffer zones around vegetable gardens and avoid direct application to any water features, bird baths, or aquatic areas on your property. Our technician reviews these specifics before every treatment visit.

For full details, see our guide to mosquito and tick spray safety for kids and pets.

Toronto Tick Treatment Schedule

Our seasonal tick program is five treatments — roughly one a month from May through September. The residual on treated vegetation wears down over a few weeks, so monthly visits keep the treated zones renewed during the months blacklegged ticks are active in Toronto:

The acaricide residual is temporary — deer, mice, and birds moving in from the ravines reintroduce ticks continuously, which is why the barrier has to be renewed rather than set once. The full five-visit season is $597 standalone, or $497 added to any BuzzSkito mosquito plan, plus HST. Many Toronto homeowners bundle tick and mosquito treatments — both can be done on the same visit, though ticks and mosquitoes are treated in different zones of the yard. See our Toronto mosquito control service for bundle pricing details.

Professional Tick Spray vs. DIY in Toronto

• Store-bought repellents protect people, not yards. DEET applied to clothing protects during a walk. Professional yard spray treats the zones where ticks wait for a passing host.
• Tick tubes target one pathway, not the whole problem. Permethrin-treated cotton tubes work via mice — useful as a supplement but don't address ticks already on your property or arriving via deer.
• Precision targeting is what makes it work. Ticks live in specific micro-habitats — the lawn-to-ravine transition, leaf litter, garden edges. Professional treatment targets these zones. Consumer products miss them.
• Toronto's ravine system is beyond your control. The Don Valley, Humber River, and Highland Creek will produce ticks every year. A treated barrier on your property is one layer of residential defence, alongside tick checks after time outdoors.

What to Expect on Tick Treatment Day

1. Visit window — We book a visit window, never an exact arrival time. You don't need to be home.
2. Property tick assessment — your technician identifies ravine edges, transition zones, and high-risk perimeters.
3. Targeted barrier application — precision spray to tick habitat: lawn-to-woods edges, garden borders, fence lines, woodpiles, under decks. 20–30 minutes.
4. Dry time — keep kids and pets off treated areas until the spray has dried, as the product label directs.
5. Email confirmation — treatment log with areas treated and next visit date.
