To better protect our communities and the environment, contractors hired by Camp Pendleton conduct annual Mosquito Control/West Nile Virus mitigation. Mosquitos are more than just a nuisance. They can transmit many serious diseases including West Nile virus and encephalitis to people and animals. Please Click here for general Mosquito information.
As part of the mitigation efforts, Bacillus thuringiensis subspecies israelensis (Bti) pellets are released by helicopter into lakes, ponds, rivers and creeks aboard Camp Pendleton. Bti is a naturally occurring soil bacterium that can effectively kill mosquito larvae present in water. VectoMax FG is used here at Camp Pendleton. Please click here for more information on VectoMax FG or here for information on Bacillus thuringiensis
There is no evidence that exposure to Bti is harmful to human health in the long term. Cases of eye and skin irritation in humans have been reported following direct exposure with some Bti products. Please see the CDC fact sheet for more information.
2022 Mitigation Schedule:
30 Sep-1 October
Pellet drops are conducted in areas where there may be stagnant water. These areas include various ranges and training areas, San Onofre Creek near San Onofre Beach, Lake O'Neill, Santa Margarita River northeast of Camp Del Mar, Case Springs and Cristianitos Creek near the San Mateo Camp Ground.
