Tick and Mosquito Control - Chemicals

What are some of the insecticides used for Mosquito and Tick Control? 

Pyrethroid insecticides, synthetic compounds derived from natural pesticides found in chrysanthemum flowers, are widely used to control insect populations, particularly mosquitoes, and mitigate the spread of diseases such as West Nile virus. Common pyrethroids include permethrin, resmethrin, and sumithrin, found in various commercial products ranging from household insecticides to lice treatments and mosquito repellents. These chemicals are generally considered safe when used correctly and pose minimal risk to human health and the environment.

In adult mosquito control, pyrethroids are applied as ultra low-volume (ULV) sprays by public health officials and trained personnel. These sprays release fine aerosol droplets that linger in the air, effectively targeting adult mosquitoes upon contact. Approved by the U.S. Environmental Protection Agency (EPA), pyrethroids are applied at extremely low concentrations, typically less than 1/100th of a pound of active ingredient per acre, ensuring effective mosquito control with minimal environmental impact.

Following application, pyrethroids settle onto surfaces but break down rapidly under sunlight and atmospheric conditions. Due to their binding properties, they do not easily penetrate the soil or contaminate groundwater, reducing the risk of environmental pollution. While exposure to pyrethroid spray may cause irritation in sensitive individuals or exacerbate respiratory conditions, adverse health effects are rare when used as directed. Accidental exposure to large amounts may result in temporary symptoms such as dizziness or nausea, but pyrethroids do not pose long-term health risks, including birth defects or cancer, when applied according to label instructions.
