"Due to the unseasonably warm winter temperatures, the SCHD Vector Control Program began treating areas within all ZIP codes by applying larvicides to standing bodies of water in February. These actions, which will continue until the first frost of the year, are consistent with its efforts to be proactive in decreasing the adult mosquito population. Larviciding is the practice of applying an Environmental Protection Agency (EPA)- registered insecticide to areas where mosquito breeding has been confirmed and is the most effective way of eliminating mosquito populations."
