Mosquito Control of Iowa uses TUG (Thermal ULV Generator) units (1.5 to 3 micron droplet size)
and can stay in the air for longer periods of time. The TUG units have became the primary ground
fogging equipment that we use in the cities. It has been determined that we achieve much better
results than "normal" ULV's. We have the TUG units mounted on all our trucks and ATVs

Adulticiding

ULV (Ultra Low Volume)

     The other method of control is the ULV (Ultra Low Volume) cold fogging which places an extremely fine aerosol in the air that floats with the breeze contacting and controlling the mosquito. This is commonly referred to as "spraying" or "fogging". The most common method is called ULV (Ultra Low Volume) cold fogging.
     We still have these units available on all our truck mounted sprayers. There are some weather conditions that the ULV's still work better (higher wind or inversion conditions)
     Our goal is to create a cloud of product that remains in the air for as long as possible. This allows active mosquitoes the opportunity to pass through it, before the cloud dissapates. The mosquito must come in contact with a droplet in order for it to work succesfully. After the cloud settles, it is no longer active and breaks down in the enviroment quickly and safely.
     Becuase of cruciality of this process, our machines are droplet tested and calibrated on site often to ensure proper application rates as per label, EPA and State regulations.
     Mosquito Control of iowa is also certified by the state of Florida in droplet analysis and sprayer calibration.

Basic Information

     Iowa Department of Ag definition of aerosol generators or "fogging machines" range from small handheld / backpack units to units that fit onto all terrain vehicles to large truck mounted units. The machines should be pre-calibrated to insure the correct droplet size and flow rate, thus insuring a correct application. Mosquito sampling, such as taking a "biting count", is usually done to be sure that an application is required. The "fogging truck" then drives at 90 degrees to, and upwind of, the area to be treated, letting the natural air currents assist the application. In large areas, such as cities or towns, this is typically repeated about every 300 feet. With small hand held type machines, a swath width of 50 feet is typical.
     Because of the extremely small amounts of material used for "fogging", once it has drifted through and area and controlled the mosquitoes, basically there is no residual material left in the area. Repeat applications can be made as often as the label allows.

Evoluer 4-4

     At MCI we "fog" using Evoluer 4-4 ULV Adulticide. It is a traditional oil-dilutable mosquito adulticide containing the proven chemistry combination of Permethrin and the synergist piperonyl butoxide (PBO). Permethrin is a pyrethroid insecticide, a synthetic form of natural permethrum.
