Hornets can be aggressive, and their stings may lead to serious allergic reactions in some individuals. Their nests, often constructed in sheltered areas, can grow rapidly, leading to larger infestations. Here are some key reasons why addressing hornet issues promptly is vital:

• Health Risks: Stings can be dangerous, particularly for those with allergies.
• Property Damage: Nests can cause structural damage to homes and buildings.
• Peace of Mind: Eliminating hornets allows for safer outdoor activities and enjoyment of your property.

Understanding Hornets and Their Behaviour in Toronto

Hornets are more than a backyard nuisance — they’re a threat to safety, especially during the warmer months in Toronto. With aggressive nesting habits and the potential to cause serious allergic reactions, hornets have become a growing concern for homeowners and businesses alike.

Whether you’ve spotted a hornet nest under your eaves, seen wasps flying around your deck, or are worried about your family’s safety during outdoor activities, this guide is designed to give you expert, practical advice. We’ll also break down services available in Toronto, costs, prevention tips, and how to safely remove them.

Hornets are a type of stinging insect closely related to wasps and yellowjackets. The bald-faced hornet, commonly found in Ontario, is black with white markings and builds large, papery nests. These nests can be found in trees, on homes, in attics, behind siding, under soffits, or even in shrubs and sheds.

Key Characteristics:

• Aggressive when threatened

• Can sting multiple times

• Nests contain hundreds to thousands

• Most active during spring and summer

• Often confused with wasps or bees

Hornets are especially dangerous for people who are allergic to their stings. A single sting can result in swelling, pain, and — in extreme cases — life-threatening reactions.

Where Hornets Nest: Common Infestation Sites

Hornets prefer sheltered spaces that are close to food and water sources. In the GTA, nests are frequently found in:

• Soffits and eaves

• Behind shutters and siding

• Under decks or porches

• Inside sheds, garages, or attic vents

• In trees or dense bushes

• Wall voids or outdoor furniture

• Near garbage bins or compost piles

Identifying the location and size of the nest is the first step in choosing the right removal approach. Attempting to treat a nest without proper tools or protective gear can lead to serious injury.

How to Safely Remove Hornets and Related Costs

What Professionals Use:

• Long-reach sprayers

Prevention Tips: How to Keep Hornets from Returning

Once a nest is removed, it’s important to take steps to stop them from rebuilding.

Preventative Measures:

• Seal gaps in siding, soffits, chimneys, and attic vents

• Remove food sources like fallen fruit, sugary drinks, or open garbage

• Keep eaves and gutters clean

• Use essential oil deterrents like peppermint or lemongrass

• Install fake nests (hornets avoid areas where other colonies are present)

Regular property inspections can help identify early signs of nesting and reduce the need for emergency treatments.

When to Book a Service

Hornets are most active between May and September, but the best time for treatment is early morning or evening when activity is lowest.

Book removal immediately if:

• Hornets are stinging people or pets

• The nest is near entrances, decks, or outdoor seating

• Children or allergic individuals are present

• You see activity inside vents, walls, or attics

Delaying removal increases the size of the colony, the cost, and the risk of harm.

Hornets vs. Wasps vs. Bees: Know the Difference

With the right support, expert help, and proven techniques, you can safely eliminate hornets — and take back your yard.
