Hornets build large, enclosed paper nests and defend them ferociously. A single disturbed hornet nest can mobilize hundreds of workers in seconds. This is not a DIY situation — and Zona has the equipment and training to handle it safely.
Hornets release alarm pheromones when disturbed, triggering nearby workers to attack in unison. A single hornet can sting multiple times. Their venom is more potent per sting than most wasp species, and encounters with large nests can be medically serious.
The bald-faced hornet (Dolichovespula maculata) is the most commonly encountered hornet species in Arizona. Despite the name, it is technically a yellowjacket species — but its behavior, size, and nest structure are distinctly hornet-like. It builds large, enclosed, papery football-shaped nests up to 24 inches in diameter, typically hanging from tree branches, eaves, or under decks.
Bald-faced hornets are highly defensive and will attack in large numbers if the nest is approached or disturbed. Unlike some insects that deliver a single sting, hornets can sting repeatedly. Their venom is potent enough to cause significant pain, swelling, and in sensitized individuals, anaphylactic shock requiring emergency treatment.
Hornet colonies reach maximum size and maximum aggression in late summer. By August and September, a single nest may house 700+ workers, all ready to mobilize if they perceive a threat. The good news: hornet colonies don't reuse nests year to year — but without removal, last year's nest is a prime location for a new queen to build next spring.
We assess the nest size, species, and location before approaching — always from a safe distance. Night or early morning treatment is far safer when most workers are inside the nest.
Our technicians wear full bee suits and use extension equipment to apply fast-acting professional products directly into the nest entry point from a safe distance. The colony is eliminated before any approach to the nest itself.
After the colony is confirmed eliminated (typically 24–48 hours after treatment), we physically remove and dispose of the nest. This removes the pheromone attractants that would draw new queens to the same location next season.
We evaluate why hornets chose that specific location and advise on any structural or landscaping changes that reduce future nesting risk.
We use direct nest treatment rather than broad landscape applications — keeping chemical use as targeted as possible while ensuring complete colony elimination. We never use unnecessary products in areas away from the nest itself.
Hornet removal requires proper equipment, products, and technique that are simply not available to homeowners. Our technicians are trained specifically for stinging insect scenarios and carry the protective equipment needed to work safely. We've handled hundreds of hornet removals across the Valley — we know exactly what we're doing, and we prioritize your safety and ours.
Don't risk it. Zona's trained technicians eliminate hornet colonies safely, every time.
No pressure. No obligation. Just straight answers.
