Communities seek to control adult mosquitoes to combat an outbreak of mosquito-borne disease or a very heavy, nuisance infestation of mosquitoes. The pesticides we register for this use are known as adulticides. They are applied either by aircraft or on the ground employing truck-mounted sprayers. State and local agencies commonly use the organophosphate insecticides malathion and naled and the synthetic pyrethroid insecticides prallethrin, etofenprox, pyrethrins, permethrin, resmethrin and sumithrin for adult mosquito control.

Mosquito adulticides are applied as ultra-low volume (ULV) sprays. ULV sprayers dispense very fine aerosol droplets that stay aloft and kill flying mosquitoes on contact. ULV applications involve small quantities of pesticide active ingredient in relation to the size of the area treated, typically less than 3 ounces per acre, which minimizes exposure and risks to people and the environment.

Adulticides can be used for public health mosquito control programs without posing risks of concern to the general population or to the environment when applied according to the pesticide label. Our evaluation of mosquito control products includes assuring that use of such products according to label directions does not pose risks to vulnerable populations, including children and pregnant women.

VectoStar offers a range of features tailored to simplify adulticide treatment reporting, which is crucial in mosquito control and management programs. Here’s how VectoStar can streamline adulticide treatment reporting and ease operations:

  1. Automated Treatment Recording: VectoStar allows for the automated recording of adulticide treatments applied in mosquito control operations. This includes details such as the date, time, location, type of treatment, dosage, and application method. By automating this process, VectoStar reduces the need for manual data entry, saving time and minimizing errors.
  2. Real-time Data Collection: With VectoStar, data on adulticide treatments are collected in real-time, providing immediate visibility into treatment activities. This real-time data collection ensures that reports are based on the most current and accurate information available, enabling timely decision-making and response.
  3. Customizable Reporting Templates: VectoStar offers customizable reporting templates specifically designed for adulticide treatment reporting. Users can create templates tailored to their specific reporting requirements, including parameters such as treatment efficacy, environmental impact, and adverse effects.
  4. GIS Integration: VectoStar integrates with Geographic Information System (GIS) software, allowing users to visualize adulticide treatment data spatially. This integration enables users to map treatment locations, identify hotspots, and analyze treatment coverage, enhancing the effectiveness of treatment reporting and decision-making.
  5. Historical Data Analysis: VectoStar maintains a database of historical data on adulticide treatments, enabling users to analyze trends and patterns over time. This historical data analysis can help identify areas with recurring mosquito problems, assess the effectiveness of treatment strategies, and optimize future treatment plans.
  6. Compliance Tracking: VectoStar facilitates compliance tracking by recording details of regulatory requirements, permits, and restrictions related to adulticide treatments. This ensures that treatments are conducted in accordance with regulatory guidelines and helps demonstrate compliance to stakeholders.
  7. Streamlined Communication: VectoStar enables seamless communication and collaboration among stakeholders involved in mosquito control operations. Users can share treatment reports, updates, and insights within the platform, facilitating efficient communication and coordination.
