Larvaciding Larvaciding is a general term for the process of killing juvenile mosquitoes while in their aquatic life stages (larvae and pupae - usually lasting between 7-10 days). Larvicide treatments can be applied from either ground or air in accordance with provisions of the Florida Pesticide Law. Contact pesticides, surface control agents, stomach toxins, and natural agents such as target-specific bacterium and natural predators are being used in Sumter County. Larviciding is a safe and effective control measure when breeding habitat remediation is not an option.
