Providing Full Service or Supplemental Application Services...
Chemical control of adult mosquitoes is used whenever and wherever staff biologists have determined mosquito populations have reached unacceptable levels. Surveillance, source reduction, larviciding, and public education should all be used to reduce the amount, frequency, and areas that adulticides are needed. However, the end result of organized mosquito management is often the application of adulticides. Chemical adulticides should be as safe and as environmentally friendly as possible. Additionally, caution should be used to avoid developing resistance to pesticides in local mosquito populations. VDCI will apply only EPA and locally registered public health pesticides labeled for mosquito control such as resmethrin, permethrin, and natural pyrethrin.
Ground Applications
Pesticides are mixed and spray equipment calibrated so that the proper pounds of active ingredient per acre are applied. All hand-held, ATV-mounted, truck-mounted and aerial adulticide equipment is calibrated and droplet size (MMD) tests conducted routinely to insure the most efficient kill rates with each application.
VDCI uses only the most up-to-date truck-mounted ULV application equipment. All vehicles are equipped with GPS
tracking units capable of delineating the spray routes of each vehicle. These units record at ten (10) second
intervals the date, time, latitude, longitude, and sprayer status (on or off) for each vehicle.

Hand-held and ATV-mounted adulticide equipment can be used to supplement truck-mounted equipment. Service requests, golf courses, parks, recreation areas, and special events can be handled with this equipment.
