Hornets in southern Ontario

Two kinds of hornet are common in Waterloo Region and Guelph.

Bald-faced hornets are black with white markings on the face and the tip of the abdomen. They’re technically a kind of yellowjacket, but everyone calls them hornets. They build the large, grey, football- or teardrop-shaped paper nests you see hanging in trees, hedges, shrubs and under eaves. A mature nest can hold several hundred hornets by late summer.

European hornets are larger, brown and yellow, and are often mistaken for very big yellowjackets. They usually nest in hollow trees, wall voids, attics and sheds, and unlike most wasps they fly at night and are drawn to porch lights and lit windows.

You may have heard about the northern giant hornet, sometimes called the “murder hornet”. It has only been reported on the West Coast, in British Columbia and Washington State, and it isn’t the hornet you have in your Kitchener backyard.

Why hornets are dangerous to remove yourself

Bald-faced hornets defend their nest aggressively. Bumping a hedge, mowing under a tree or shaking a branch can bring dozens of them out at once, and each one can sting more than once. Nests are often hidden in thick foliage until you’re right on top of them, and many are high enough to need a ladder, which is the worst place to be when hornets come out.

Store-bought sprays don’t reach the centre of a large paper nest, where the queen and young are. Knocking a nest down with a stick or hose just releases an angry colony. For anyone with a sting allergy, any hornet nest near the house is a job for a professional.

Our hornet nest removal process

Free phone estimate.Tell us where the nest is, how high and roughly how big. A photo from a safe distance helps.
Assessment.A technician confirms the species, finds the nest entrance and checks for any other nests on the property.
Treatment.We apply a Health Canada-registered insecticide into the nest entrance, reaching the queen and the colony inside.
Removal.Once the colony is dead, exposed nests in trees, hedges and eaves are taken down and bagged. Nests inside walls are treated and left to dry out.
Aftercare.We’ll tell you how long to keep kids and pets away and when it’s safe to seal any gaps.

You may see a few hornets around the spot for a day or two. These are workers that were away when the nest was treated.

How much does hornet nest removal cost?

Typical prices before HST:

Your technician confirms the price before starting. See the pest control cost guide.

Exposed hornet nest in a tree, hedge or under eaves: from about $200
Nest inside a wall, soffit or attic: from about $250
Each additional nest at the same visit: about $50 to $75

When hornets are most active

Queens come out of hibernation in spring and start nests in May. Nests grow quickly through June and July, and hornets are most numerous and most defensive from August into September. The colony dies off after the first hard frost. Old nests aren’t reused, but new queens may build nearby next year, so it’s worth checking trees and eaves each spring.

How to reduce hornet nests around your home

Walk the yard in May and June and look up into trees, hedges and under eaves.
Trim dense hedges and shrubs near doors and walkways so nests are easier to spot.
Keep garbage and green bins sealed and away from patios.
Turn off or switch to yellow porch lights if European hornets keep coming to windows at night.
Seal gaps in siding, soffits and attic vents in late fall, after nests are dead.

Hornet nest removal: FAQ

How much does hornet nest removal cost?

Hornet nest removal starts at about $200 before HST for an exposed nest in a tree, hedge or under the eaves. Nests inside walls, soffits or attics start at about $250. Each additional nest at the same visit is about $50 to $75. Your technician confirms the price before starting.

Should I leave a hornet nest alone?

If a nest is high in a tree at the back of a large yard, away from doors, play areas and paths, leaving it until frost is often fine, because hornets also eat other insects. If it’s near a door, deck, hedge you trim, window or anyone with a sting allergy, it should be treated.

Will hornets come back to the same nest next year?

No. Hornet colonies die off in late fall, and only new queens survive the winter, hiding under bark, in woodpiles or in sheltered spots. Queens don’t reuse old nests. They may build a new nest nearby the following spring, so check trees, hedges and eaves in May and June.

Do you remove hornet nests from trees?

Yes. Most bald-faced hornet nests we remove are in trees, hedges and shrubs. We treat the nest first so the colony dies, then take it down and bag it where it’s reachable. Nests very high in large trees may be treated and left in place to dry out.

Are European hornets dangerous?

European hornets are large and their sting is painful, but they’re usually less defensive than bald-faced hornets unless the nest is disturbed. They nest in hollow trees, walls and attics and are active at night, so they often show up at lit windows. A nest inside the house should be treated by a professional.
