READY TO PROTECT YOUR HOUSE FROM PESTS THIS SPRING?
If you’ve lived in Edmonton for any length of time, you know the feeling — the snow starts to pull back, the air gets that first real hint of warmth, and suddenly you’re noticing things in your home that weren’t there a few weeks ago. A line of tiny ants near the kitchen sink. A cluster of sluggish flies buzzing against the attic window. Droppings in the garage you’re pretty sure didn’t come from the dog.
Welcome to spring pest season in Edmonton.
After more than 21 years of treating homes across Edmonton, St. Albert, Sherwood Park, Spruce Grove, and the surrounding communities, we can tell you this with confidence: spring is the single most important time of year to get ahead of pests. The good news? A little knowledge and a few smart steps right now can save you a lot of stress — and money — later in the season.
In this guide, we’ll walk you through exactly which pests wake up during Edmonton’s spring thaw, what to watch for, what you can do on your own, and when it’s time to call in a professional. Let’s get your home ready.
Why Spring Is Peak Pest Season in Edmonton
Edmonton’s spring doesn’t arrive gently. We get weeks of freeze-thaw cycles — cold snaps at night, warming days that melt snow and open up gaps in foundations, siding, and rooflines. That pattern creates the perfect conditions for pest activity.
Here’s what’s actually happening. Pests that spent the winter hiding inside your walls, attic, or crawlspace start moving again as temperatures rise. Mice that have been breeding quietly since November start venturing out. Cluster flies that tucked themselves into wall voids back in September wake up and head toward your windows. And outside, the ground thaws enough for ants and early wasp queens to begin foraging and scouting for nest sites.
Edmonton’s river valley and extensive green spaces are a big part of what makes this city beautiful — but they also support a thriving ecosystem of insects and rodents that naturally move toward homes when conditions shift. Add in the typical suburban landscape of attached garages, deck structures, and mature trees close to rooflines, and you’ve got a recipe for spring pest pressure.
None of this is cause for panic. It’s just the reality of living in Alberta. And when you understand what’s happening, you’re already a step ahead.
The Most Common Spring Pests in Edmonton (and What to Watch For)
Every spring, our phones start ringing with the same handful of concerns. Here are the pests we treat most often between late March and early June — and the signs that tell you they’ve moved in.
Ants — Especially Carpenter Ants
Ants are one of the first pests to show up in Edmonton homes each spring. As soon as the ground thaws enough for foraging, they start looking for food and moisture — which is why you’ll often spot them first in kitchens, bathrooms, and laundry rooms.
The ones to pay closest attention to are carpenter ants in Edmonton. Unlike regular house ants, carpenter ants tunnel into wood to build their nests. They don’t eat the wood — they excavate it — but over time, the structural damage can be serious. If you’re noticing small piles of fine sawdust near baseboards, window frames, or door casings, that’s a sign carpenter ants may already be at work.
A few ants trailing across your counter in spring is normal. A steady stream of large black ants emerging from a wall? That’s worth getting checked. Our team provides thorough insect control in Edmonton and we can identify the species and recommend the right approach — before the colony gets established.
Cluster Flies
If you’ve ever walked into your attic or a sunny upstairs room in March and found dozens of large, sluggish flies bumping against the window, you’ve met cluster flies. They’re one of the most common — and most misunderstood — spring pests in Alberta.
Cluster flies aren’t like house flies. They don’t breed indoors or feed on garbage. What happens is they enter your home in the fall, tuck themselves into wall voids and attic spaces to overwinter, and then wake up as spring temperatures rise. They’re drawn to warmth and light, which is why they congregate near windows.
The good news: cluster flies in Alberta don’t bite, don’t spread disease, and they’re not a sign of a dirty home. The bad news: they can show up in large numbers, and if they found their way in last fall, they’ll likely do it again next year unless you seal the entry points.
We’ve written a detailed guide on cluster fly removal in Alberta that covers exactly how to handle them — including long-term prevention so they don’t come back.
Mice and Rats
Here’s something a lot of Edmonton homeowners don’t realize: if mice got into your home last fall or winter, they’ve been breeding the whole time. A single pair of mice can produce up to 60 offspring in a year. By the time spring arrives, what started as one or two mice in November can be a much bigger problem.
Spring is often when people discover the extent of a rodent issue. You’re cleaning out the garage, moving stored boxes, or opening up the shed for the first time — and you find droppings, gnaw marks on wiring or cardboard, shredded insulation, or the unmistakable smell of a nest.
Don’t wait on this one. Mice cause real damage — chewed wires are a fire hazard, and droppings can carry harmful bacteria. If you’re seeing signs, it’s worth getting a professional assessment. We deal with rodent problems across Edmonton every single day, and our approach focuses on removal, sanitation, and sealing the entry points so they can’t come back.
If you dealt with mice over the winter, our guide on winter mice control in Edmonton covers what to look for and how the problem typically develops. Or see our rodent service details get started with our Mice and rodent control in Edmonton.
Wasps — The Queens Are Already Scouting
Most people think of wasps as a summer problem, and that’s fair — the big nests and aggressive behaviour usually peak in July and August. But the foundation for every summer wasp nest is laid right now, in early spring.
Here’s how it works. Wasp queens that survived the winter emerge as temperatures warm up and start scouting for nest sites. They’re looking for sheltered spots — under eaves, inside soffits, behind shutters, in sheds, along deck railings, and under steps. At this stage, the queen is alone and building a small starter nest. If you catch and remove it now, you prevent a colony of hundreds (or thousands) from establishing over the summer.
This is one area where a spring inspection makes a huge difference. A quick walk around your home’s exterior — checking eaves, roofline edges, and any sheltered nooks — can save you from a much bigger wasp removal Edmonton job in July. And if you spot early nest activity in a hard-to-reach area, that’s exactly the kind of situation where our drone inspections come in. We can survey rooflines, soffits, and upper stories safely and thoroughly without missing a thing. Trust our team of Edmonton wasp removal experts to get the job right the first time!
Spiders
Spiders tend to follow their food source. As insects become more active in spring, spiders move with them — which is why you might notice more cobwebs in corners, window frames, and garages this time of year.
The vast majority of spiders in Edmonton are completely harmless. They’re actually helpful — they eat the insects you don’t want around. That said, we understand that a lot of people simply aren’t comfortable sharing their home with them, and that’s perfectly okay.
If you’re seeing a sudden increase in spider activity, it often means there’s a larger insect population nearby drawing them in. Addressing the underlying insect issue usually takes care of the spider problem too.
Your Spring Pest Prevention Checklist for Edmonton Homes
You don’t need to be a pest control expert to make your home a lot less inviting to unwanted guests. Here are the steps we recommend to every Edmonton homeowner this time of year — the same advice we’d give a neighbour.
- SEAL THE GAPS - Walk your home's exterior and look for cracks in the foundation, gaps around utility pipes, and spaces where siding meets trim. Remember the pencil rule: if a pencil fits through a gap, a mouse can squeeze through it. Caulk, steel wool, or expanding foam can close most of these entry points.
- CHECK YOUR SCREENS - Inspect every window and door screen for tears, holes, or loose frames. This is your first line of defence against flies, mosquitoes, wasps, and spiders.
- TRIM VEGETATION BACK - Shrubs, branches, and vines touching your siding or roofline create natural bridges for ants, spiders, and rodents. Keep a clear gap of at least 30 centimetres between plants and your home's exterior.
- INSPECT YOUR ROOF AND VENTS - Check soffits, fascia, and roofline edges for gaps or damage. Make sure roof vents, bathroom exhaust vents, dryer vents, and your chimney cap all have intact screening. This is where cluster flies, birds, and wasps typically find their way in.
- CLEAN UP STORAGE AREAS - Garages, sheds, and basements with cluttered cardboard boxes are prime nesting habitat for mice. Switch to sealed plastic bins where possible, and keep items off the floor.
- SECURE YOUR GARBAGE - Tight-fitting lids on garbage and recycling bins go a long way. Rinse out containers that held food, and clean your BBQ grease tray — it's a magnet for ants, wasps, and rodents.
- MOVE FIREWOOD AWAY FROM THE HOUSE - Store it at least a few metres from your foundation and off the ground. Firewood stacked against the house is a welcome mat for carpenter ants, spiders, and mice.

When DIY Isn't Enough and How We Can Help
Prevention goes a long way. But sometimes, despite your best efforts, pests find a way in — or they were already there before you had a chance to seal things up. That’s when it’s time to call in a professional, and here’s what sets our approach apart.
- We inspect thoroughly — including places you can’t easily reach. Our team uses drone inspections to survey rooflines, soffits, upper stories, and other hard-to-access areas that are often missed during a standard walkthrough. We take pest control to new heights — literally — because the entry points you can’t see are usually the ones causing the problem.

We provide quotes within 15 minutes and offer same-day service across Edmonton, St. Albert, Sherwood Park, Spruce Grove, Leduc, Fort Saskatchewan, and the surrounding area.

- We offer ongoing protection. If you want to stay ahead of pests year-round — not just in spring — our Home Shield Protection packages start at $80 per month for homes up to 2,000 square feet. It’s the kind of consistent coverage that prevents problems before they start, so you’re not scrambling every time the season changes.

Frequently Asked Questions About Spring Pest Control in Edmonton
What pests come out in spring in Edmonton?
The most common spring pests in Edmonton are ants (especially carpenter ants), cluster flies, mice and rats, early wasp queens, and spiders. Activity typically ramps up in late March and April as temperatures rise and the spring thaw opens up entry points around homes.
How do I know if I have a pest problem after winter?
Watch for droppings in your garage, basement, or utility room. Look for gnaw marks on cardboard, wiring, or stored items. Listen for scratching sounds in walls, especially at night. Sawdust piles near baseboards may indicate carpenter ants, and sluggish flies at attic windows usually mean cluster flies overwintered in your home.
Is spring pest control safe for kids and pets?
It absolutely can be — and it should be. At All About Pests, we use eco-friendly, family-safe treatments specifically chosen to be effective against pests while being safe for children and pets. We always discuss treatment details with you before we begin so you know exactly what’s being used in your home.
How much does spring pest control cost in Edmonton?
Costs depend on the type of pest and the size of your home. We publish a public price guide so you can see our rates upfront — no surprises. For ongoing protection, our Home Shield Protection packages start at $80 per month for homes up to 2,000 square feet.
Can I do pest prevention myself, or do I need a professional?
Many prevention steps — sealing gaps, trimming vegetation, cleaning storage areas — are things every homeowner can and should do. But if you’re dealing with an active infestation, seeing signs of structural damage (like carpenter ants), or can’t access the areas where pests are entering (rooflines, soffits, attic spaces), a professional inspection is the smart move. Our drone inspections let us check every hard-to-reach spot safely and thoroughly. These same areas — soffits, eaves, and rooflines — are also prime nesting spots for pigeons and starlings in spring, which our team can address at the same time.
