Yard insects don’t just randomly show up—they’re triggered by environmental conditions that make your property ideal for nesting and feeding.
Moisture buildup (after snow melt or rain)
Decaying organic matter (leaves, wood, mulch)
Warm temperatures (perfect breeding conditions)
Food sources (garbage, pet food, plants)
👉 In Alberta, the snowmelt season is a major trigger, waking up dormant insect colonies underground.
