San Diego County's Vector Control Program plans to conduct its initial aerial larvicide drops of the year next week. The operation aims to minimize the spread of diseases such as West Nile virus by targeting mosquito breeding sites in up to 52 water channels.

The aerial larvicide applications are scheduled for Wednesday, April 23, extending to April 24 if necessary, aiming to cover nearly 1,400 acres of remote breeding locations.

Since the early 2000s, the County has used helicopters to disperse larvicide over difficult-to-reach stagnant water areas where mosquitoes can potentially breed. The method has been a part of the County's efforts to combat the spread of the West Nile virus, which mosquitoes can transmit from infected birds to people.

Although the West Nile virus has had a mild impact in recent years, with three or fewer cases annually since 2017, County officials maintain a vigilant approach to control mosquito populations. The monthly larvicide drops form part of an Integrated Vector Management Strategy that includes surveillance of potential breeding areas, different larvicide application techniques, and offering free mosquito-eating fish.

County officials encourage residents to take proactive steps in minimizing mosquito habitats around their homes. This includes eliminating standing water and using mosquito-eating fish in backyard water sources like ponds and neglected swimming pools.

Due to the presence of invasive Aedes mosquitoes, which can transmit diseases such as Zika and dengue, public cooperation has become increasingly essential. The County recommends following the "Prevent, Protect, Report" guidelines to safeguard against mosquito bites, such as wearing long clothing or using insect repellent and ensuring screens are intact.

For mosquito-related concerns, including the reporting of increased activity or dead birds, residents can reach out to the County's Vector Control Program.
