A routine morning walk turned into a frightening ordeal when a Summerlin woman and her 25-pound dog were chased and repeatedly stung by a swarm of aggressive bees at Cottonwood Canyon Park. The dog needed emergency veterinary care after suffering multiple stings, and the owner was treated for several stings to her head and neck. She said the two sprinted up park stairs and made it to their car only after being pursued for roughly a quarter mile. The woman said she suspects the insects were Africanized bees and is now warning other walkers to be especially mindful of pets and children.
What happened at Cottonwood Canyon Park
Anne Wayman told KTNV that she and her dogs were heading back to their car when the swarm hit and that one of her pets, Alfie, "was literally covered with bees." According to the report, Alfie suffered about 20 stings and Wayman about eight. Alfie later had to return to an emergency clinic, where he received an injection of Kenalog and was put on steroids. Wayman said she sprayed mace into the air in an effort to stop the insects as they chased the pair along the trail.
Why entomologists watch for Africanized bees
Africanized honey bees are the same species as European honey bees but behave much more defensively. UC Agriculture and Natural Resources notes they can pursue intruders for up to a quarter mile. The National Park Service also warns that aggressive colonies can send out hundreds of bees to defend a wide area and that swarming becomes dangerous when a nest is disturbed. That kind of defensive behavior helps explain how an ordinary encounter on a trail can suddenly become hazardous for small pets, children, and anyone who cannot get away quickly.
Protecting pets and yourself
If a pet is stung multiple times, owners are advised to seek veterinary care immediately. Basic first aid includes removing visible stingers, applying cold compresses, and following a veterinarian's guidance on antihistamines such as diphenhydramine at roughly 1 mg per pound for dogs, according to PreventiveVet. Emergency treatment may include injectable antihistamines, steroids, and pain control, and Trupanion notes that severe reactions can require hospitalization. If you hear loud buzzing or spot a cluster of bees, experts advise moving to a closed car or building and contacting park staff or a licensed removals service rather than trying to handle a swarm on your own.
Park response and local resources
In a statement to KTNV, the Summerlin Council said it follows a "pro-active and balanced approach to bee management" that includes traps, routine inspections, and signage when hives are identified. Residents are urged to report swarms to park staff and to call licensed removers. Local rescuers such as Vegas Bees often relocate temporary swarms in the valley. Officials remind visitors not to swat at bees and to get to shelter quickly if a swarm turns aggressive.
Wayman said she is grateful both dogs survived and hopes the episode raises awareness about swarm season. She urges visitors to keep dogs leashed, avoid lingering near likely nesting spots such as brush piles or tree cavities, and have a plan to get to a closed vehicle if buzzing intensifies or a bee lands on you.
