The focus of the mosquito control program is on the larval stages of mosquito development. Mosquito Control will conduct adult mosquito control operations when there is evidence of elevated risk for the transmission of mosquito-borne disease to humans. The decision to implement adulticiding operations is based on a number of factors including evidence of disease in mosquitoes that bite mammals, relative population of adult mosquitoes in the local area, types of mosquitoes in the local area, human population density, and weather conditions.
When all other modalities have not brought about satisfactory control of nuisance mosquitoes the staff uses ground based adulticiding equipment. Mosquito Control has a Becomist® 1500 truck mounted ULV machine and two Electramist® truck mounted ULV machines. This state of the art adulticiding equipment is professionally calibrated during each spray season. The MCMC uses Scourge® (resmethrin) or Fyfanon® (malathion) based upon field determinations made by the assistant superintendent. The MCMC also has a truck mounted thermal fogger, two hand held foggers and two hand held ULV generators. This equipment is used only for the purpose of controlling large populations of nuisance mosquitoes as determined by our surveillance and potential vector-borne diseases.
Recognizing that source reduction is not achieved by the use of pesticides, the staff is continually exploring alternate approaches to achieve more permanent methods of controlling mosquitoes.
The Mosquito Control Division is statutorily eligible for participation in the NJ State Mosquito Control Commission Airspray Program. For the last 15 years we have not had the necessity to rely on aerial adulticiding. We will continue to properly advertise the possibility that there may be a time when aerial adulticiding is needed. The same products and equivalent ULV equipment are mounted and used on the helicopter.
