Hornets are the most aggressive stinging insects in Las Vegas. Two species are present in the Las Vegas Valley: the bald-faced hornet (Dolichovespula maculata) and the European hornet (Vespa crabro). Both are larger than yellow jackets and paper wasps, both sting repeatedly without dying, and both release alarm pheromones that trigger mass defensive attacks when a nest is disturbed. Hornet nests are typically aerial — attached to trees, shrubs, eaves, utility poles, and building structures — and grow from softball-size in spring to watermelon-size or larger by late summer. Do not attempt to remove a hornet nest without professional equipment and training. A disturbed nest can result in dozens of stings within seconds.
Both hornet species release alarm pheromones when the nest is disturbed. The chemical signal recruits the entire colony to attack — a single disturbance can result in dozens of stings within seconds. Never approach an active hornet nest.
For anyone with a stinging insect allergy, a single hornet sting can trigger anaphylaxis — a life-threatening reaction. Seek emergency medical attention immediately if the stung person shows difficulty breathing, widespread swelling, dizziness, or hives.
Treatment strategy differs by species. Bald-faced hornets build visible aerial nests — the homeowner usually sees the nest. European hornets nest in voids and hollow trees — the nest is often hidden until the colony is well-established. Both warrant professional treatment; neither should be approached without protective equipment.
Dolichovespula maculata
Despite the name, bald-faced hornets are technically a type of yellow jacket — classified as hornets because of their large size and aerial paper nest. Black with distinctive white markings on the face, thorax, and abdomen. Builds large aerial paper nests — inverted teardrop shape attached to trees, shrubs, eaves, utility poles, and building overhangs. Nests start softball-size in spring and can grow to watermelon-size or larger by late summer if untreated.
Vespa crabro
The largest hornet in North America — large, reddish-brown with yellow markings and a fuzzy thorax. Typically nests in hollow trees, tree cavities, attic voids, and wall voids — nests are often hidden and not discovered until a colony is well-established. By the time most nests are found, they are the size of a basketball. Less aggressive than bald-faced hornets unless nest is directly disturbed. Often seen hovering around garbage and compost areas.
Hornet danger is not a marketing exaggeration. The combination of repeat stinging, alarm pheromones, and large colony size produces a stinging-insect risk substantially higher than yellow jackets or paper wasps. The left column lists the danger factors; the right column lists what to absolutely avoid doing if you find a nest.
Unlike honey bees, hornets do not lose their stinger after stinging. A single hornet can sting multiple times in rapid succession, and a colony can sting dozens of times in seconds.
Both bald-faced hornets and European hornets release alarm pheromones when disturbed. The chemical signal recruits the entire colony to defend the nest — turning one alarmed worker into a full-colony response in seconds.
Of all stinging insects in the Las Vegas Valley, bald-faced hornets respond most quickly and most aggressively to disturbance. Provocation thresholds are far lower than yellow jackets or paper wasps.
A single disturbed nest can result in dozens of stings within seconds. The injury severity is significantly higher than a typical wasp encounter and warrants immediate medical attention for anyone stung multiple times.
For anyone with a stinging insect allergy, a single hornet sting can trigger anaphylaxis — life-threatening without immediate emergency care. Confirmed allergies on the property elevate every hornet call to emergency status.
Bald-faced hornets build visible aerial nests in the open. European hornets nest in voids and hollow spaces that are often invisible from the ground. The six locations below are the patterns PCI technicians inspect first on every hornet call.
The most common bald-faced hornet location in Las Vegas. Inverted teardrop paper nests hang from larger branches and are visible from the ground once the colony develops.
Attached to building structures under eaves and inside soffits, especially on shaded sides of the home. Treatment requires care to avoid driving the colony into the attic during application.
Carports, pergolas, sheds, utility poles, and outdoor playground equipment all serve as aerial nest attachment points and warrant inspection in any visible-nest call.
European hornets often enter the attic through roofline gaps and establish nests inside the void. Discovery typically happens only when a worker is heard or seen indoors.
Wall voids entered through exterior gaps, utility penetrations, and damaged stucco are common European hornet nest sites. Void treatment is required — physical nest removal is rarely safe.
Hollow trees, dead branch cavities, and hollow wood fence posts are classic European hornet nest sites. Easy to miss until activity around the cavity is observed.
Pest Control Inc’s Health Conscious Service Program is an Integrated Pest Management approach designed for Southern Nevada pest conditions. For hornets it means species-specific treatment, professional protective equipment, and night-timed application for maximum effectiveness and minimum risk. Never a quick daytime spray on a fully active colony.
FOUR-STEP HORNET PROCESS
Licensed PCI technician confirms the species (bald-faced hornet or European hornet), locates the nest, assesses nest size and access, and identifies any high-risk factors before treatment is scheduled.
Professional products applied directly to the nest and entry points at night when the colony is less active and most workers are present in the nest. Protective equipment is used; treatment is timed for maximum effectiveness and safety.
Physical nest removal where accessible after the colony is eliminated. Void treatment for European hornet wall and attic nests where physical removal is not safe or practical.
Follow-up confirms no new activity has resumed. Prevention recommendations cover early-season inspection, entry point sealing for void-nesting species, and exterior conditions that attract stinging insects. Every PCI hornet service is backed by the money-back guarantee.
Hornet calls are not a routine spray. They require species ID, risk assessment, protective equipment, and the discipline to wait for the right time of day. Here is what makes Pest Control Inc different on a pest where doing it right matters more than doing it fast.
