Bug Season 2026: What Alberta's Forecast Means for Your Truck's Radiator

You don't get to pick the day the bugs show up. One dry week in July the ditches along the highway start to move, and by the time you've noticed, the front of your truck is already wearing them. The only real choice you get is whether you're covered before that week arrives — and heading into the summer of 2026, the early signs are worth a look.

Every year the Government of Alberta runs a province-wide grasshopper survey and publishes a forecast for the season ahead. This year's outlook describes a setup that favours the pests. The winter was mild, so very few overwintering eggs were killed off. The previous fall came in warm and dry — close to ideal for the egg-laying that sets up the next year's hatch.

And the province still flags outbreak potential across southern Alberta and along the eastern border with Saskatchewan, the same stretches that have carried the heaviest activity in recent years. Layer that on a population entomologists say has been climbing across the Prairies for several years, and the ingredients are on the table. The province counts them as grasshoppers; out on the highway, they're just bugs — and your grille doesn't care what we call them.

The weather is the wild card

Here's the honest part: a forecast is not a guarantee, and the weather still gets the final say. The bugs are at their most fragile right after they hatch, and a cool, wet stretch in late spring can knock them back hard — that's exactly what spared much of the province from a feared outbreak a couple of summers ago. But the reverse is just as true. When it turns hot and dry, the young insects can tear through an entire growth stage in about four days instead of sitting around for weeks. A few hot weeks at the wrong time is all it takes to turn a "moderate risk" map into a windshield you need a scraper for in July.

The broader 2026 summer outlook leans toward heat with interruptions rather than one locked-in heat dome, and across most of Alberta the spring arrived wetter than the brutally dry recent years — good news on balance, though the far south remains the driest corner and the one most primed for trouble. The takeaway isn't panic. It's that the risk is genuine, uneven from region to region, and impossible to time precisely from the seat of your truck.

What that means for your radiator

When the swarm does hit, your radiator is the first thing to pay for it. Bugs pack into the cooling fins, choke off the airflow your engine depends on, and on a hot day that's how a temperature gauge starts to climb. We've already laid out the full case — and the repair-bill math behind it — in Why Your Truck Needs a Bugscreen, so there's no need to walk through all of it again here. The short version: a bugscreen stops the insects at the grille before they ever reach the radiator, and the little that lands on it rinses off with a hose.

Beat the swarm, not the calendar

The catch with prevention is that it only works if it's already on the truck. Once the ditches are alive and you're driving through them at highway speed, the damage is happening in real time — there's no getting ahead of it then. Because nobody can call the exact week the bugs peak, the safe move is simply to be covered before the season gets rolling. And we're already into it.

That part is easy. Every bugscreen we build is hand-made right here in Edmonton and cut to your truck's exact grille, with popular makes and models already on patterns we keep on file. Bring the truck by the shop on 154 Street, or send clear photos and measurements, and we'll have you covered before the next hot stretch does its worst.
