As the snow melts and Edmonton begins to thaw, many homeowners are already thinking ahead to spring yardwork, gardening, and—unfortunately—pest activity. Every year, the weather plays a major role in shaping which pests will thrive and when. Based on current forecasts, Edmonton is heading for a hot, dry summer in 2025, and that means some pests will be more active than usual—while others may take a back seat.
Understanding how seasonal patterns affect pest populations can help you take proactive steps now to prevent infestations before they start. Here’s what to expect and how to prepare.
Hot and Dry? Expect More Wasps Than Mosquitoes
In years with hotter, drier weather, wasp activity tends to spike—especially by mid to late summer. With fewer rainy days to disrupt their nesting and more opportunities to forage, wasps become more aggressive and more likely to establish colonies around homes and yards.
The key to controlling wasps is early action. In the spring, only the queens are active, scouting for nest locations and beginning the process of colony building. If wasp queens are caught and removed during April and May, you can drastically reduce the number of wasps around your home by summer.
What you can do:
-
Check eaves, sheds, and attics for early nest activity
-
Contact a professional for early wasp inspections and targeted treatments
-
Keep garbage bins sealed and outdoor food covered
Mosquitoes May Be Less of a Concern
Mosquito populations typically surge during cool, wet summers when there’s plenty of standing water for breeding. With a dry season ahead, we expect lower-than-average mosquito activity, especially in areas without natural water sources.
However, if your property has shaded, damp areas or garden irrigation systems, mosquitoes can still become a problem.
Prevention tips:
-
Drain any standing water early in the season (e.g., birdbaths, planters, gutters)
-
Trim back heavy vegetation to reduce resting areas
-
Schedule mosquito treatments in high-risk zones if needed
Ant Activity Likely to Increase
Warm, dry conditions can also lead to earlier and more aggressive ant foraging. Carpenter ants and pavement ants are particularly active in dry soil, where they can build expansive colonies around homes and driveways.
Once they find access to food or moisture inside your home, they can quickly become a recurring issue. That’s why sealing up entry points and maintaining cleanliness in spring is crucial.
Watch for:
-
Ant trails around windowsills, baseboards, and outdoor foundations
-
Sawdust-like material near walls (a sign of carpenter ants)
-
Nests in garden beds or along patios
Rodents May Move Indoors for Water
While rodents like mice and voles are usually more of a winter concern, they can remain active in spring—especially if dry conditions limit their outdoor access to food and water. In these cases, they may move indoors looking for shelter and hydration.
Spring is the perfect time to:
-
Inspect and seal small openings around foundations and vents
-
Clean out garages and sheds
-
Watch for signs of nesting (droppings, gnawed packaging, or shredded insulation)
Spiders and Cluster Flies Are Waking Up Indoors
As the weather warms, overwintering pests like spiders and cluster flies start to emerge from attics, basements, and wall voids. While these pests are typically harmless, their presence can be unsettling and may point to other insect activity in your home.
Reduce indoor pest sightings by:
-
Vacuuming corners, window sills, and basement spaces
-
Replacing or repairing window screens
-
Scheduling an interior spring pest inspection
