Trucks are fascinating because they can serve a variety of specialized functions. This often involves unique equipment like snow plows and dump beds. However, one essential function only requires a reasonable amount of bed space and a nocturnal driver.
Across municipalities in the country, trucks equipped with large foggers patrol the streets to control mosquito populations. This task is especially crucial in coastal regions where these pests proliferate, and some specialized vehicles have been performing this function for decades. Miami-Dade County has been using spraying trucks since 1935, while Massachusetts' Bristol County Mosquito Control Project has been monitoring and managing these insects since 1959.
The trucks designated for this purpose are standard pickups fitted with large pesticide tanks and automated sprayers in the truck beds. They drive slowly through affected areas to release the pesticide, typically at night when most mosquito species are most active. According to the county website, Escambia County, Florida, typically operates its fogging trucks from dusk until 10 p.m. In New Bedford, Massachusetts, spraying occurs between 2 a.m. and 10 a.m., as reported by The New Bedford Light.
If you encounter one of these trucks, the clouds of insecticide emerging from the bed will be quite noticeable. Local officials informed The New Bedford Light that the spray is harmless to humans and other mammals; however, drivers do their best to avoid proximity to people. In Escambia County, spray operations are also canceled if wind speeds are below 2 mph or exceed 10 mph, or if temperatures fall below 60 degrees Fahrenheit.
Municipalities determine when to dispatch spray trucks based on calls from residents (Miami-Dade County advises residents to call 311 to request spraying) and data collected from mosquito traps. These traps are essential for monitoring mosquito populations and checking for disease-carrying mosquitoes, the latter evaluated through testing of individual insects captured in the traps. Both Massachusetts and Florida offer opt-out options for those who, for instance, keep bees on their property and wish to avoid unintended harm.
While this may not be pushing these trucks to their limits, it is indeed meaningful work, and that’s what trucks are designed for.
