LAS VEGAS (KLAS) - Mosquito activity in the Las Vegas valley has seen a significant spike during the fall monsoons, leading to a local animal hospital issuing a warning to pet owners about a new variant of mosquitos prevalent in the area.

The specific type of mosquito causing concern is the Aedes aegypti, which is primarily active during the day and is attracted to stagnant water. Dr. Christopher Yach, the hospital director at West Flamingo Animal Hospital, is advising pet owners to consider heartworm disease testing six months after possible exposure to these mosquitoes.

Dr. Yach emphasized the importance of being cautious, stating, "If there is a pet who has come from elsewhere with heartworm, and with more mosquitos, it will be more likely that disease spreads."

The Southern Nevada Health District initially discovered the presence of Aedes aegypti mosquitos in 2017 and determined that they originated from California, Arizona, and Mexico. Since then, the American Heartworm Society has reported an increase in disease cases and identified new hotspots.

The rising concern surrounding heartworm transmission has prompted many pet owners, such as Carol Kutz, to consider heartworm testing for their furry companions, like Marley and Bitsy.

Veterinarians explain that heartworms do not spread directly from one dog to another. Instead, if a mosquito bites an infected dog, it can acquire the disease and subsequently transmit it to another dog.

Dr. Yach mentioned that due to recent rain in August and September, there is an increased risk of heartworm transmission. He recommends getting a heartworm test six months after possible exposure, and for those who were in a heartworm-prone area in August, February would be an appropriate time for testing.

However, prevention methods may vary depending on an individual's lifestyle and environment, and therefore it is advised to consult with a veterinarian for personalized guidance.

Teri Wissinger, a licensed veterinary technician who recently moved to Las Vegas from Washington, shared her experience, stating, "I definitely recommend heartworm prevention if they go to dog parks, camping, hiking, or anywhere they are going to be exposed."

In light of the situation, the Southern Nevada Health District is urging the public to report any noticeable increase in mosquito activity, as such information can help monitor and address the issue effectively.

As pet owners remain vigilant in protecting their beloved companions, the local animal hospital stresses the importance of taking preventative measures against heartworm disease, as the Aedes aegypti mosquito continues to pose a threat in the Las Vegas valley.
