ULV (Ultra-Low Volume) is a method of applying pesticides that targets which of the following?

• A. A method of pesticide application that uses very small amounts of concentrated spray to target adult mosquitoes.
• B. A device used to measure spray droplet sizes.
• C. Large volumes of dilute spray used for larval habitats.
• D. A certificate for handling toxic materials in storage.

Answer: (A)

Ultra-Low Volume spraying means using very small amounts of concentrated pesticide sprayed as a fine mist to reach adult mosquitoes. The tiny droplets stay suspended in the air long enough to contact flying mosquitoes, making it effective for outdoor adult control while using far less chemical than traditional spraying. This method is specifically about targeting adults, not measuring droplet sizes, larval habitats, or storage/certification concerns. So the description that best fits ULV is the one that emphasizes the small-volume, concentrated spray designed to hit adult mosquitoes.
