Mosquito larvae can survive in as little as one half inch of standing water.  During optimal weather conditions, the mosquito lifecycle is complete (from egg to adult)  in as little as 3-5 days. Because mosquitoes have the potential to emerge so quickly, it is important to eliminate any water where larvae will survive. A few examples of places you may find larvae are potted plants with the dish underneath, dog water bowls, empty trash cans, bird baths, bromeliads, rain gutters cluttered with leaves, stagnant kiddy pools, buckets, old tires, yard toys, and boats. By doing your part in reducing the mosquito population, you will be helping contribute to the mission of AMCD: protecting our residents from mosquito-borne viruses. The viruses of most concern in St. Johns County are Eastern Equine Encephalitis Virus and West Nile Virus. Click here for information on signs and symptoms of these conditions.
