Bees, Wasps & Hornets: A Toronto Pest Control Guide

Recently, a concerned homeowner in Toronto’s GTA called us: a young boy had spotted a swarm of wasps under the porch eaves. As an Insectica technician, I geared up, ready to handle a busy summer nest. Carefully peeking, I identified paper wasps clustered on their nest. The mom was anxious, young children and pets played nearby, and nobody wanted surprise stings.

Here’s a full guide

This is a typical day in the life of a Toronto pest control professional: assess, reassure, and protect. Here’s a full guide to bees, wasps, and hornets, their differences, risks, DIY tips, and when to call professionals. (wasps-hornets)

  • Key Takeaways
  • Know your stinger: Bees are pollinators, usually gentle; wasps and hornets are aggressive predators.
  • Risks vary: Wasps and hornets can sting repeatedly; bees sting only once but still cause pain.
  • DIY limits: Small nests may be manageable with caution, but active or large nests require trained pros.
  • Professional removal: Safely removes nests, protects children/pets, and prevents re-infestation.
  • Prevention matters: Sealing gaps, removing food attractants, and early inspections reduce risks.

Bees, Wasps & Hornets: What’s the Difference?

Bees (honeybees & bumblebees)

  • Hairy, round bodies, golden-yellow and black
  • Pollinators feeding on nectar; sting only once when threatened
  • Beneficial to gardens and crops
  • Fun fact: honeybees have five eyes, two large compound eyes and three tiny ocelli

Wasps (yellowjackets & paper wasps)

  • Sleek, smooth bodies with narrow waists; shiny black and yellow
  • Predators and scavengers (eat insects or sweets)
  • Can sting multiple times, aggressive if disturbed

Hornets

  • Large wasps, aggressive defenders of their paper nests
  • European hornets & bald-faced hornets can measure over an inch
  • Will vigorously defend their colony if approached

Summary: Bees = fuzzy pollinators, mostly gentle. Wasps/Hornets = lean predators, aggressive, and can sting repeatedly. (ontario.ca) 

Risks to Humans and Pets

  • Wasps & hornets: Repeated stings, venom injection, potential for severe reactions
  • Bees: Single sting, usually only if crushed or provoked
  • Pets: Sensitive areas like noses or eyes are at risk
  • DIY removal risk: Swarming and multiple stings; professional removal is safest

DIY Tips (Small Nests Only)

  • Soap Spray at Night: Mix 2 tbsp dish soap with water, spray small nests at dusk
  • Natural Repellents: Peppermint, lemongrass, clove oils diluted in water deter wasps
  • Traps: Soda bottle traps with vinegar + sugar attract and trap scouts

Only attempt DIY on small nests in low-traffic areas. Large, high, or active nests require professional help.

When to Call the Professionals

Call Insectica Pest Control if you notice:

  • Large nests or swarms
  • Nests in high or hard-to-reach areas (roof, attic, wall voids)
  • Allergic individuals at risk
  • Repeated sightings or indoor activity

Professional removal benefits:

  • Full nest and queen removal
  • Eco-friendly bee relocation (if applicable)
  • Targeted, child- and pet-safe treatments
  • Quick, one-visit solutions

Typical professional removal costs a few hundred dollars depending on nest size and type.

After Removal: Will They Return?

  • Fully treated nests are abandoned; wasps usually don’t reuse treated nests
  • New nests may appear if attractants remain
  • Prevention is key:

Action Steps:

  • Seal garbage cans and compost bins
  • Remove fallen fruit promptly
  • Seal entry points around walls, eaves, and foundations

Bees are pollinators; local regulations often encourage relocation over extermination.

What to Do If Stung

Bee stings:
  • Scrape stinger out gently, wash area, apply ice, and use antihistamine cream
Wasp/Hornet stings:
  • Clean area, cold compress, pain relief or antihistamines as needed
Emergency:
  • Multiple stings, allergic reactions, or nests near children/pets require immediate professional assistance
