In spring Toronto GTA comes with it some tiny invaders – ants! Imagine walking into your kitchen in early May and seeing a line of little ants trekking across the counter toward your jam. It’s a classic springtime scene.
Ants are usually the first pests to wake up after winter, and if you’re not careful, they can quickly turn into a colony in your home or business. At Insectica Pest Control, we hear this story every year. From houses and apartments to restaurants, offices, and even factories, ants can find their way inside through cracks and crevices. Knowing when to spray or treat is key to stopping an infestation before it starts.
Meet Toronto’s Ant Invaders
In the GTA, a few ant species are widespread. Carpenter ants are the big ones (up to 25 mm long!) that chew through wood – think window frames, door jams or even furniture. They’re usually black or red-black, and a surprising sight when spotted indoors. Then there are pavement ants – small brown or black ants often nesting under sidewalk cracks or driveways. Pavement ants “typically find their home on the sidewalk in gaps between slabs” and can invade basements and garages, especially in winter. Don’t forget pharaoh ants: tiny reddish-brown ants only a few millimetres long, but dangerous in their way. Pharaoh ants love kitchens, pantries and hospitals – anywhere with sugar or grease. They scurry along baseboards and counters, contaminating food with bacteria such as Salmonella.
No matter the species, these ants have one thing in common: they follow food and water into our homes. Carpenter ants forage in trees and logs then wander inside in spring; pavement ants come indoors as it cools; pharaoh ants stay inside year-round if they can. “Ants emerge in spring in response to warmer temperatures and longer days. As summer heats up, they search for food and reproduce”. In short, when it gets warm, ants get busy.
Seasonal Timing for Ant Treatments
So, when should you spray for ants? Pest pros agree: early spring is prime time. That’s when most ant colonies are small and new, and sprays or baits can wipe them out before they explode in population. One expert note that “the best time to start spraying insecticides around the house is typically during spring when temperatures are mild, and pests start to become more active.”. By treating in April or May (as soon as the snow melts), you hit ants as soon as they wake up for the year.
Local technicians in Toronto have seen this pattern too. They observe that as spring arrives, “ants… become more active, searching for food and breeding grounds”. Summer then brings the peak of ant activity – all the ants you missed in spring are now swarming, nesting and foraging. For example, backyard picnics and moist gardens in July can become ant hotspots. That’s why Insectica often recommends two treatments per year: one in early spring, and a follow-up in late summer or early fall. The spring spray nips new colonies in the bud, and the fall service catches any survivors before they march indoors for winter.
There is indeed no single “ant season” – you might see ants any warm day. But by planning around the seasons, you prevent the worst. We’ve seen houses that never had a single ant after a preventive spring treatment! And if you do catch sight of ants in midsummer or even fall, don’t panic – it’s never too late. The longer you wait, the bigger the colony. Even a few ants can mean thousands more in the attic or under your house. If in doubt, call Insectica and we’ll inspect. We tailor our ant control solutions to each situation – some homes need extra focus on cracks and woodwork, others on kitchens and landscapes. We’ll advise the best timing and method for you.
(Quick Tip: In summer, ants usually forage in the early morning or late afternoon when it’s cooler. If you’re applying a spot spray yourself, catching them then helps. But professional baits and barriers are still best.)

Common Questions (and Friendly Answers!)
Q: When exactly should I schedule ant treatments? We recommend early spring, around April–May, to break up colonies as they start. A follow-up in late summer or early fall is wise, too, especially if you had problems last year. Think of it like weed prevention: pull them before they bloom. If ants pop up any time, give us a call – better safe than sorry!
Q: I saw only one ant – is that a big deal? One ant can quickly be a thousand. Ants leave scent trails, so whenever you see even one, there may be many you don’t see. We advise an inspection at the first sign, to find and treat the source nest. (Remember: Insectica’s inspections and quotes are free, so you’ve got nothing to lose by checking.)
Q: What does ant control cost in Toronto? Costs vary by infestation size and location, but for perspective a standard home treatment in the GTA might run a few hundred dollars. In fact, local sources note typical single treatments can be $250–$300 up to $500–$800 for very large or difficult cases. We focus on affordable pricing and will give you an exact quote up front. Plus, our repeat discounts and occasional coupons make our costs very competitive.
Q: Can I DIY ant sprays instead of calling? Store sprays seem cheap, but they usually only kill the ants you hit – not the hidden nest. Worse, misused products can harm children, pets or your plants. Our pros use specialized baiting and targeted treatments that kill the entire colony, including the queen. Plus, we follow all safety rules so you won’t have to worry about toxicity. When you factor in warranty and time saved, professional service is often cheaper in the long run.
Q: How long do treatments last? Many treatments keep ants at bay for months. We stand behind our work with a 3-month warranty. After that, we recommend seasonal check-ups. Think of it as annual maintenance – ants are always out there! We’ll remind you when it’s time for a tune-up.
