The mission of the East Flagler Mosquito Control District is the suppression of those mosquito species that may cause illness or significant discomfort, within a specific control area and with minimal environmental impact.

For mosquito control pesticides to be effective at reducing the mosquito population, the mosquitoes must be actively flying so they can contact the suspended droplets produced by the fog truck. A very small amount of pesticide, less than 1 ounce per acre, is aerosolized using a blast of air. The term for this is “ULV” or ultra-low volume.

Mosquito Control monitors the population of adult mosquitoes daily utilizing a network of traps placed around the district and are counted and identified to species. Once the population of mosquitoes exceeds the baseline, treatments can be applied to reduce the mosquito population. This is a required strategy as federal and state law requires the presence of mosquitoes to be verified before any application of these products.

Most species of mosquitoes are active from sunset to sunrise and this is when mosquito control conducts spray operations. Since the mosquitoes must be actively flying to come in contact with the sprayed pesticides, we cannot spray when conditions are too windy, it’s raining, and also when temperatures are too low for mosquitoes to be active.

The district is working with the County EOC to arrange for aerial spraying of mosquitoes over large areas of Flagler County. This will be necessary because widespread flooding will produce a high number of mosquitoes. These mosquitoes can migrate up to ten miles, so large areas will have to be treated to prevent infiltration. The larger the mass of mosquitoes, the greater the area that needs to be treated to keep the number of mosquitoes coming into populated areas at acceptable levels.

The District routinely treats by air using a helicopter and has done so for over thirty years. The state assistance through FEMA will allow for several planes to spray large parts of the County over a couple of nights.
