Professional Hornet Removal Services in Calgary
Discovering a hornet nest on your Calgary property poses an immediate, serious safety risk to your family, pets, and visitors. While technically a aggressive, aerial-nesting species of yellowjacket, the stinging insects Calgary homeowners encounter are almost exclusively bald-faced hornets. Recognizable by their white-and-black markings and large, football-shaped paper nests, hornets build high up in trees, under roof eaves, or along soffits.
Unlike more docile solitary insects, hornets are exceptionally territorial. When a nest is disturbed, whether by a passing lawnmower, low-hanging tree branch, or curious pet, the colony responds with fierce, synchronized defense. Bald-faced hornets mark intruders with alarm pheromones, triggering dozens of hornets to swarm and attack simultaneously. Their smooth stingers allow them to sting repeatedly, injecting potent venom that causes severe pain, localized swelling, and potential anaphylactic reactions in allergic individuals.
Attempting to knock down or spray a hornet nest without professional equipment is highly dangerous. Expert hornet removal requires specialized full-body protective sting suits, Health Canada–approved residual dusts, and professional high-reach application equipment. At Dynasty Pest Control, our licensed technicians safely neutralize the entire colony at the core, extract the nest structure, and apply protective barriers to keep your property safe and sting-free.
How Can We Help?
Common Calgary Hornet Species
Calgary homeowners frequently encounter three primary stinging insects during the warm months: yellowjackets, bald-faced hornets, and paper wasps.
- Yellowjackets: Compact, hairless, and aggressively attracted to sugary foods and proteins late in the season, yellowjackets build large paper nests underground, inside wall cavities, or beneath decks. Read more on wasps in Calgary
- Bald-Faced Hornets: Recognizable by their distinct black-and-white bodies, these aggressive hornets construct large, football-shaped grey paper nests high up in trees, under eaves, or on building soffits.
- Paper Wasps: Slender with long legs that dangle in flight, paper wasps build open, umbrella-like comb nests in sheltered spots like window frames, shed rafters, and fence posts.
While paper wasps are generally docile unless directly threatened, yellowjackets and bald-faced hornets fiercely defend their territory, often swarming and stinging repeatedly when their nests are disturbed. Read more on Calgary Wasp Species.
Nest Locations
Hornets frequently build nests in high-traffic residential areas such as roof eaves, under deck joists, inside the sheds, underground burrows, and behind wall voids. While visible exterior nests are easily spotted, hidden nests inside building cavities pose the greatest threat.
Tackling a wall-void or underground nest with DIY spray often backfires drastically. Over-the-counter insecticides irritate the colony without reaching the core queen, prompting hundreds of defensive wasps to swarm inward through drywall cracks, electrical outlets, or light fixtures directly into your living space. Professional exterminators utilize specialized dusts and pressurized injectors to eliminate hidden colonies safely without trapping insects inside.
Our Hornet Control Process
Our professional wasp removal process ensures safe, permanent colony elimination through the following main steps:
Property Inspection: We offer Comprehensive site assessment. Our certified technicians thoroughly examine your property to locate active flight corridors, assess nest size, and determine potential structural entry points.
Nest Identification: We come and check Species & confirm their location. We pinpoint the exact hornet species and mapping coordinates, whether situated high in a tree canopy, beneath a soffit overhang, or tucked within a shed framing.
Professional Treatment: We offer Targeted knockdown application. Wearing full-body sting suits, our technicians apply Health Canada–approved residual dusts or pressurized formulations directly into the primary nest cavity to neutralize the queen and active colony safely.
Follow-Up & Prevention: Our process includes Extraction & residual barrier. Once activity completely ceases, we physically extract accessible paper nest structures, apply protective exterior deterrents, and seal entry crevices to prevent new queens from rebuilding.
Timing : Spring vs. Late-Summer Nests
Addressing stinging insect nests early in spring yields the safest, most effective results. Spring nests are small, containing only an initial queen and a few developing larvae. By late summer, however, these colonies explode into hundreds of aggressive workers fiercely defending mature paper structures. Treating early prevents exponential population growth, eliminates territorial behavior around outdoor spaces, and ensures a far simpler, safer removal process before nests expand into structural voids or high-traffic areas.
Hornet Problems We Handle
Nests in Trees & Shrubs: Bald-faced hornets frequently construct large, grey paper structures concealed within dense foliage, posing immediate sting risks to anyone pruning branches or mowing lawns.
Under Eaves, Soffits & Siding: Roof overhangs, high eaves, and soffit crevices offer sheltered, prime real estate for expanding hornet colonies right near high-traffic home entrances.
Sheds, Garages & Attics: Sheltered outbuildings and unsealed attic spaces provide ideal protection for hornets to construct massive internal nests uninterrupted.
Large or High-Altitude Nests: Massive, mature aerial nests situated high up in tree canopies or multi-story rooflines require specialized extension equipment, pressurized injectors, and full protective gear for safe extraction.

Frequently Asked Questions: Wasp & Hornet Removal
How much does hornet nest removal cost in Calgary?
Hornet removal cost generally depends on several factors:
Height & Accessibility: Accessible ground-level or low-eave nests start at a lower baseline, while high-altitude nests in tall tree canopies or multi-story rooflines requiring specialized extension ladders and reach equipment are priced accordingly.
Nest Size & Complexity: Larger, mature late-summer colonies require specialized pressurized dust applications and labor.
Service Speed: Standard scheduled visits vs. priority emergency same-day dispatches. Dynasty Pest Control provides clear, upfront pricing before beginning any work.
Are treatment products safe for my children and pets?
Yes. We utilize Health Canada–approved products applied with precision techniques directly into the nest matrix or entry points. For exterior spray applications, we ask that children and pets remain indoors during treatment and stay off treated areas for 1 to 2 hours until sprays dry completely. Once dry, the area is completely safe for normal activity.
Do you physically remove the nest itself?
Yes, whenever the nest is structurally accessible. Once technicians neutralize active stinging insects, we remove accessible exterior paper nests from eaves, decks, sheds, and trees to eliminate unsightly structures and attractive pheromone trails. For hidden nests deep inside wall voids or beneath concrete slabs, we neutralize the interior colony and seal exterior entry gaps.
How quickly does Hornet Removal treatment work?
Our specialized Hornet Removal treatments begin working instantly upon application, with the majority of the colony neutralized within a few hours. Complete colony elimination occurs within 24 hours as returning foraging workers come into contact with the treated nest entrance.
What is the difference between wasps, hornets, and honey bees?
Wasps and hornets (like yellowjackets and bald-faced hornets) have smooth, slender bodies, build grey paper nests, and can sting repeatedly when defending their territory. Honey bees and bumblebees are fuzzy pollinators with stouts bodies. At Dynasty Pest Control, we help identify the species first and offer live relocation options for beneficial honey bee swarms whenever possible.
How do I know if I have a hornet nest?
You can confirm a hornet nest by looking for key physical and behavioral signs around your property:
Distinctive Nest Architecture: Large, grey, papery structures shaped like a football or inverted teardrop, typically suspended high in tree branches, thick shrubs, roof eaves, or soffits.
Focused Flight Paths: A steady stream of large, black-and-white hornets entering and exiting a single hole at the bottom of the papery structure.
Increased Sightings: Frequently spotting bald-faced hornets hovering around outdoor lights, deck railings, or water sources.
Are hornets dangerous?
Yes, hornets pose a significant safety risk. Bald-faced hornets are intensely defensive of their territory. Unlike honey bees, a single hornet can sting repeatedly without dying, injecting potent venom that causes severe pain and intense localized swelling. When a nest is disturbed, even accidentally by a passing lawnmower or wind, hornets release alarm pheromones that trigger a aggressive, synchronized attack from dozens of colony members. These mass-stinging events can lead to severe allergic reactions or life-threatening anaphylactic shock.
Can hornet nests be removed safely?
Yes, when performed by trained professionals. Attempting DIY removal with store-bought sprays is extremely dangerous, as it rarely neutralizes the entire queen-centered colony quickly enough to prevent aggressive swarming. Dynasty Pest Control technicians use heavy-duty protective sting suits, high-reach pressurized equipment, and Health Canada–approved formulations to safely eliminate the internal colony. Once neutralized, accessible nest structures are physically extracted to ensure complete removal.
How long does hornet treatment take?
The primary treatment and nest application takes 30 to 60 minutes. Our knockdown treatments begin working instantly upon application, eliminating the vast majority of active hornets inside the nest within minutes. Returning foraging workers will come into contact with the residual application and be eliminated over the next 12 to 24 hours, resulting in complete colony eradication.
