Maricopa County Sees Surge in Mosquito Complaints Amidst Increased Rainfall
Residents of Maricopa County are experiencing a significant rise in mosquito-related issues this season, with the Vector Control Division recording over 6,000 complaints. This marks a dramatic increase compared to the previous year, which saw roughly 1,000 such reports.
The uptick in mosquito activity coincides with recent rainy weather, according to the Vector Control Division. John Townsend, the Division Manager, elaborated on the situation during an appearance on PBS’s Arizona Horizon, highlighting the presence of both daytime and nighttime mosquito species in the area.
Townsend pointed out the potential dangers posed by the nighttime mosquitoes, which have the ability to transmit viruses such as West Nile virus and St. Louis encephalitis. “West Nile, which everybody talks about, are the nighttime biting mosquitoes and they pick that virus up from the birds,” he explained.
Interestingly, these nighttime mosquitoes are a relatively recent arrival to the Phoenix area, having been introduced about 25 years ago. Townsend noted, “Those are mosquitoes that were imported here about 25 years ago. We didn’t have them before that and they breed right in people’s backyards. They’re container breeders. They prefer human blood as their bloodmeal.”
Daytime mosquitoes, in contrast, are less of a health concern, and the cooler night temperatures expected soon are likely to inhibit their breeding.
Residents seeking information on managing mosquito populations or wishing to file a complaint can do so via the Vector Control Division’s website.
