Wasps Worse Than Usual? Trap or Spray Depends on This
Yard and outdoor · PROBLEM-FIRST
Late August through September is the peak of wasp season across Ontario, including Niagara. Wasp colonies reach their largest size of the year in this window, and as queens slow egg-laying, the worker wasps that spent summer feeding larvae switch to foraging for sugar as natural food sources dry up, which is why they show up around drinks, fallen fruit, and backyard barbecues far more than earlier in summer. Niagara's orchards and backyard fruit trees give foraging wasps an added draw once fruit ripens and windfalls start dropping. What actually helps depends on the situation, and a trap and a spray are not interchangeable: a trap works passively, luring wasps in with an attractant and reducing general activity in a yard over the days it is out, while a contact spray treats one specific, visible nest immediately from a safe distance. A nest that is large, inside a wall cavity or attic, high off the ground, or near a doorway used every day is a safer job for a licensed pest control professional than a DIY spray, and a known wasp or hornet sting allergy anywhere in the household is also a reason to call one rather than approach a nest directly. This section explains that distinction before naming any product.

Who this isn't for
This is not for a nest that is large, inside a wall cavity or attic, high off the ground, or near a doorway used every day; that is a safer job for a licensed pest control professional than a DIY spray or trap. It is also not for any household with a known wasp or hornet sting allergy; approaching a nest directly in that situation is a real safety risk regardless of which product is used, and calling a professional is the right call instead.
