Hurricane Response Guide for Environmental Public Health Professionals
Before implementing biological control methods, it is essential to check with STLT authorities to ensure compliance with regulations and prevent unauthorized species introductions. Chemical Control Adulticide application is an effective mosquito control strategy that involves applying insecticides in ultra-low volumes (ULV) using aircraft or ground equipment to quickly reduce mosquito populations and interrupt disease transmission. Proper application requires careful calibration of spray equipment and appropriate timing to minimize the impact on non-target insects. Application methods include handheld units, small vehicles, and trucks. Implementing weather-tracking policies and local monitoring is necessary to determine how weather conditions influence control decisions. Regular calibration of application equipment, checking flow rates, and measuring droplet size and deposition are essential. Continuous testing for insecticide resistance using bottle bioassays and cage tests is crucial, and appropriate changes should be made if resistance is detected. Larviciding, which involves targeting mosquito breeding sites with various formulations, can reduce the reliance on and expense of adulticides. However, after a disaster, larviciding may be limited to small areas due to the large, affected area, damaged infrastructure, and shortage of trained personnel, unless applied aerially. Note: Understand the requirements of the licensing agency and the product’s label. Know the water discharge pesticides permit requirements of your state. The state, tribe, or territorial required forms and other operational records produced must be reviewed for accuracy and to ensure that sufficient information is collected and recorded. Data generated by spray units mounted to the spray trucks must be kept and reviewed in addition to all other operational documents to determine compliance to STLT and federal laws.
