Best Wasp and Hornet Traps and Sprays for Niagara's Late-Summer Wasp Season (August 2026): 3 Real Options Compared
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 and natural food sources like flowers and insects dry up, the worker wasps that spent summer feeding larvae switch to foraging for sugar, which is why they show up around drinks, fallen fruit, and backyard barbecues far more than they did in July. Niagara's orchards and the fruit trees common in its backyards give foraging wasps an added draw once fruit ripens and windfalls start dropping this time of year. Below are three real, currently-listed wasp and hornet control products on Amazon.ca, a non-toxic trap and two contact-kill sprays, compared by what each listing itself states. No price or availability is shown here, because both change; check the current listing on Amazon.ca before buying.
A trap and two sprays compared
RESCUE! WHYTR-BB8 Wasp, Hornet & Yellow Jacket Trap
Listing title: "Rescue WHYTR-BB8 Wasp, Hornet & Yellow Jacket Trap"
- Mechanism: Non-toxic reusable trap, no chemical killing agent (manufacturer description)
- Design: Two-chamber design with separate top and bottom entrances (manufacturer description)
- Attractant: Includes attractant, rated for roughly a 2-week supply (manufacturer description)
- Listing caution: A second ASIN (B00BPTN6YC) is also indexed under amazon.ca for a product with this same title; confirm which listing is current before buying
The passive option of the three: hang it and it draws wasps in over time rather than treating a specific nest on contact, so it works best set out ahead of when wasp activity peaks rather than reached for once a nest is already a problem.
View on Amazon.ca →Raid Wasp and Hornet Killer, 400g Aerosol
Listing title: "Raid Wasp and Hornet Killer, Wasp Killer Spray for Home Use Kills Bugs and Nests on Contact, Including Paper Wasps, Yellow Jackets, Mud Daubers and More, 400g (Pack of 1)"
- Format: 400g aerosol can (listing title, confirmed by direct fetch)
- Kills: Paper wasps, yellow jackets, mud daubers, and other bugs and nests, on contact (listing title)
- Spray reach: Up to 5.7 metres (18.7 feet), per manufacturer description text repeated across multiple Canadian retailer listings (not confirmed on amazon.ca body text directly)
- Electrical safety: Listed as non-conducting up to 41,000 volts (same cross-retailer sourcing)
A direct fetch confirmed this exact listing title and can size on amazon.ca. The two Canada-wide retailer chains listed above use the same description text as the Raid product page, corroborating rather than a single unverified source.
View on Amazon.ca →OnGuard Hornet & Wasp Blaster Aerosol Spray, 400g
Listing title: "OnGuard Hornet & Wasp Blaster Aerosol Spray Can 400g | Kills Wasps, Yellowjackets and Hornets on Contact | Ready to Use"
- Format: 400g aerosol can (listing title)
- Kills: Wasps, yellowjackets, and hornets, on contact (listing title)
- Spray reach: Reaches nests from more than 15 feet away, roughly 4.5 metres (manufacturer description, indexed; direct amazon.ca fetch returned a server error on this attempt)
- Electrical safety: Listed as non-conducting up to 41,000 volts (same indexed description)
Marketed toward the professional pest-control side of the category (the product description names it as a brand used by pest control professionals), with a slightly shorter stated reach than the Raid can compared here.
View on Amazon.ca →How this comparison was put together
This page compares one non-toxic wasp trap and two contact-kill aerosol sprays currently listed on Amazon.ca. Wasp and hornet control was chosen for this seasonal slot, not by an automated trending-products feed but by season: late August through September is documented peak wasp season across Ontario, driven by colonies reaching maximum size while natural food sources dry up. A repeatable way to detect what is genuinely trending on Amazon.ca, rather than choosing a category by hand each time, remains a named next step for this lane, carried over from the first picks page.
A direct fetch of the live Amazon.ca product page succeeded for one of the three products (Raid) and returned the page title and can size, but not a full body specification table; the same fetch failed with a server error for the other two (the RESCUE trap and OnGuard). For those two, and for the two numeric spray-reach figures not present in any listing title, this page uses text that recurs identically across multiple independent Canadian retailer listings for the same product (Home Depot Canada, Canadian Tire, Lowe's Canada, Real Canadian Superstore, Walmart Canada), which reflects the manufacturer's own product description distributed to every retailer rather than a single unverified source. A search restricted to the amazon.ca domain also surfaced two different ASINs indexed under the same RESCUE trap listing title; that discrepancy is named on the product card above rather than silently resolved. No price or availability is shown, because both change after this page is written; the current figure is always on the Amazon.ca listing itself, linked above.

FAQ
What is the difference between a wasp trap and a wasp and hornet spray?
A trap like the RESCUE WHYTR-BB8 compared here works passively: it lures wasps in with an attractant and holds them, with no chemical killing agent, so it reduces general wasp activity in a yard over the days and weeks it is out. A contact spray like Raid Wasp and Hornet Killer or the OnGuard Hornet & Wasp Blaster is an aerosol meant to treat one specific, visible nest immediately from a safe distance. A trap is for ongoing activity around a patio or garden; a spray is for a nest that needs to be dealt with now.
Why do wasps get worse in Niagara in late August?
Wasp colonies reach their largest size of the year in late August, and as queens slow egg-laying, the worker wasps that spent the summer feeding larvae are freed up and switch to foraging for sugar as natural food sources like flowers and insects start to dry up. That combination, more wasps and a stronger pull toward exposed food and drinks, is documented across Ontario and Canada generally, not a claim specific to one week's weather in Niagara.
When should a wasp or hornet nest be handled by a pest control professional instead of DIY?
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. A known allergy to wasp or hornet stings anywhere in the household is also a reason to call a professional rather than approach a nest directly. Both sprays compared here are made for treating a visible, reachable outdoor nest from a distance; neither is a substitute for professional removal of a nest inside a structure.
