Mosquito activity is inextricably linked to temperature and moisture, leading to significant variations in seasonality across different geographic regions of the United States.
When a mosquito bites a dog or cat, the immediate physical irritation is only the surface of the problem. Mosquitoes serve as vectors for serious, sometimes fatal, health conditions in animals.
Heartworm disease is the most critical mosquito-borne threat to pets in North Carolina. It is transmitted exclusively through the bite of an infected mosquito. When the insect feeds, it deposits microscopic larvae into the animal’s bloodstream, which eventually mature into foot-long worms that lodge in the heart, lungs, and associated blood vessels. Veterinary data indicates that the incidence rate of heartworm exposure is exceptionally high for unprotected pets in the state.
While more commonly associated with human and equine health, viruses such as West Nile and Eastern Equine Encephalitis (EEE) can affect domestic dogs and cats. Though clinical disease in pets is rare, bites from infected mosquitoes can compromise an animal’s immune system.
Pets frequently suffer from mosquito bite hypersensitivity an allergic reaction to the proteins in mosquito saliva. This causes intense pruritus (itching) and localized swelling. Because animals cannot effectively soothe the itch, they often bite or scratch the area raw, creating open wounds that are highly susceptible to secondary bacterial infections.
The foundation of pet safety is consistent, year-round heartworm medication prescribed by a veterinarian. Because of Wake County’s prolonged mosquito season and mild winters, stopping preventatives during the cooler months leaves pets highly vulnerable to unseasonably warm breeding spikes.
Because mosquitoes require stagnant water for their larval stage, eliminating standing water is the most effective way to reduce local populations. Homeowners should regularly audit their property to:
While the Asian Tiger Mosquito bites during the day, many other species are crepuscular, meaning they are most active at dawn and dusk. Limiting a pet’s outdoor exposure during these peak hours can significantly reduce bite frequency.
