Vectobac 12AS

None of these larvicides are bioaccumulate in the environment. They kill the mosquito larvae present at the time of application and then rapidly decompose. If a heavy rain occurs a few days after treating with these larvicides there is no alternative but to treat once again. 

The larvicides are used in liquid form by ground and granular form by air.  Ground treatments are typically conducted using ATVs, which are equipped with a tank of larvicide and a GPS monitoring system to document where the chemical was applied.  Aerial treatments are performed by a local subcontractor using a turboprop crop-dusting plane.

 

Adulticides

Dibrom

Permanone 30-30

Delta-Guard

Adulticides are used in liquid form by ground and air.  Ground treatments are typically conducted using spray trucks or hand held foggers.  Aerial treatments are performed by a subcontractor during widespread mosquito outbreaks or during a medical emergency when there is a threat to the public of a mosquito transmitted pathogen (e.g. St. Louis encephalitis or West Nile). "Dibrom" is reserved for broad-scale aerial applications in case of disease threat or massive infestations ; "Permanone" is what we normally use in our ULV spray trucks; "DeltaGuard" is used for spot applications if there is suspicion of Zika virus in an area.
