Quick Take

• Goal: Reduce stings and nuisance around patios, decks, and play areas—without creating new problems.
• Approach: Combine prevention, a few homemade deterrents/traps for light activity, and purpose-built lures (like the RESCUE! WHY® Trap + Attractant) for sustained control.
• Safety first: Severe infestations or nest removals—especially for hornets—are best handled by pros.
  

Identify What You’re Dealing With

• Yellowjackets (ground or structure-nesting): Short tempers, love proteins in spring/early summer and sweets late summer/fall. Often the “picnic raiders.”
• Paper wasps (umbrella nests under eaves): Less aggressive but will defend nests. Attracted to protein early season, sweets later.
• Bald-faced hornets (aerial paper nests): Large, very defensive; do not DIY nest removal.
  Right ID matters because bait choice and placement change with species and season.
  

Prevention That Actually Works

1. Sanitation & Food Control

• Tighten lids on garbage/recycling; rinse cans/bottles.
• Cover beverages and protein foods outdoors; clean drips/spills promptly.
• Pick up fallen fruit; keep compost secured.
  

2. Seal Access

• Caulk gaps around soffits, siding, meter boxes.
• Screen attic/roof vents; repair tears in window/door screens.
  

3. Landscape Tweaks

• Move flowering plants that draw wasps away from eating areas.
• Mow regularly; reduce ground burrow sites where yellowjackets might nest.
  

Homemade Solutions (Good for Light Activity)

These are deterrents and low-intensity traps—useful for reducing casual traffic. They won’t replace a targeted lure during peak season.

A) Simple DIY Bottle Trap (Sweet Bait, Late Summer/Fall)

• Cut the top off a plastic bottle; invert it as a funnel.
• Bait: 1 cup water + ¼ cup sugar + a squeeze of honey or jam + a splash of apple cider vinegar (discourages honeybees).
• Add a few drops of dish soap to break surface tension.
• Hang 20–30 ft (6–10 m) away from people; 4–6 ft (1.2–1.8 m) high; replace bait every 3–5 days.
  

B) Protein Bait (Spring/Early Summer)

• Use a small piece of canned tuna/sardine in a lidded container with puncture holes (so they can enter for scent but not easily exit).
• Place downwind and away from dining areas.
• Rotate to sweet baits later in the season.
  

C) Peppermint “Keep-Off” Spray (Deterrent for Surfaces, Not Nests)

• Mix 1 cup water + 10–15 drops peppermint oil in a spray bottle; add a few drops of mild dish soap.
• Lightly spray around railings, table bases, and under benches (avoid food prep surfaces).
• Reapply after rain. Effect is modest and short-lived—but helpful as part of a broader plan.

D) Decoy Paper Nests (Mixed Results)

• Hang in early spring to deter new paper-wasp nest starts.
• Ineffective against established nests and most yellowjackets/hornets.
  

Important: Never pour gasoline/chemicals into ground nests; it’s illegal, dangerous, and contaminating. If you find a nest near high-traffic areas, call a professional—especially for hornets.

Why Purpose-Built Traps Help (and Where DIY Falls Short)

Homemade traps catch some foragers, but they don’t optimize species-specific attractants and often sit too close to people. Purpose-built solutions use tuned lures and trap geometry to pull pressure away from living spaces and reduce sting risk during peak season.

The RESCUE!® WHY Trap & Attractants 

The RESCUE! WHY® Trap (Wasp–Hornet–Yellowjacket) is designed to attract multiple species across the full season, using a protein-plus-sweet strategy and a durable, reusable body.

Set-Up & Placement (Canada Best Practices)

• Distance: Hang 20–30 ft (6–10 m) from patios, doors, play spaces to draw insects away from people.
• Height: 4–6 ft (1.2–1.8 m) off the ground; place upwind of the area you’re protecting so scent plume pulls foragers away.
• Sun vs. Shade: Bright shade or partial sun (intense midday heat can dry lures faster).
• Timing:
  • Spring (protein phase): Set traps early to intercept queens/workers (use the protein component).
  • Mid/Late summer–fall (sweet phase): Switch/refresh sweet attractant as diets pivot to sugars.
    

Maintenance

• Check every 2–4 days during hot spells; refresh lure/attractant per label.
• Rinse the trap when changing baits; wear gloves and keep away from children/pets.
• Rotate locations if activity patterns shift (after lawn work, storms, or new food sources).

Safety Notes

• Do not place traps near beehives or pollinator plants in peak bloom.
• Always follow label directions; Canadian pesticide rules apply.
• Traps reduce pressure but do not replace pro removal of active hornet nests or yellowjacket colonies in structures.
  

Seasonal Control Plan (At-a-Glance)

• Early Spring: Prevention + decoys (optional); inspect eaves; deploy WHY trap with protein lure to intercept queens.
• Late Spring–Mid Summer: Keep sanitation tight; maintain protein lure; add DIY traps away from people.
• Late Summer–Fall: Swap to sweet attractants (or combo lures); increase trap density before long weekends.
• Late Fall: Remove inactive nests (paper wasps) only when empty; store traps clean and dry for next season.
  

When to Call a Professional

• Visible aerial nest (especially bald-faced hornet).
• Ground nest near play or pet areas.
• Allergy risk in the household.
• Repeated stings or persistent activity inside walls/structures.
  

FAQs

Will traps attract wasps to my yard?

They attract foragers already in the area and help pull them away from where you sit/eat—if placed 20–30 ft away.

What bait should I use and when?

Protein early (spring/early summer); sweet later (late summer/fall). The WHY trap system is designed to cover both phases.

Can I spray store-bought wasp killer on a nest?

Surface sprays on an active hornet or large yellowjacket nest are risky and often ineffective. In Canada, follow label directions strictly—or hire a pro.

Do decoy nests work?

Sometimes for early-season paper wasps, not for established nests or most yellowjackets/hornets.

Quick Step-By-Step (Some Homes)

1. Clean up attractants (garbage, fruit, grill).
2. Set a WHY trap 20–30 ft away, 4–6 ft high; protein bait now, sweet later.
3. Add one DIY bottle trap farther out as a secondary pull.
4. Refresh attractants regularly; move traps if wind/traffic patterns change.
5. Call a pro for any nest on the house, in the ground near play areas, or any hornet nest.
   

Bottom Line

A smart mix of sanitation, spacing, and species-appropriate lures keeps patios and decks comfortable through the Canadian season. Use DIY traps for light pressure, but rely on a RESCUE! WHY® Trap + Attractants—placed well away from people and maintained regularly—to meaningfully reduce wasp, yellowjacket, and hornet activity. For visible or high-risk nests, bring in a professional and keep your family (and pets) safe.
