You can fill the solution tank with both oil or water based solutions. Inside the solution tank there is a pump, which is used to pump the fogging liquid from the tank to the heating assembly where it gets heated to a high temperature and vaporizes when released from a nozzle. Under the handle there is a fogging trigger. On the left side of the fogger is an auto ignite switch that lights a spark to the heat assembly when pressed. The heat assembly part of the fogger consists of multiple parts such as a burner, coil, safety basket, solution supply tube and a nozzle.

hi I bought the vector by100 fogger and I was wondering what is the best solution to put in the top tank for killing mosquitos. diesel goes on the bottom only it looks like. I was thinking of using a mixture of pyrethrin permethrin diluted with deodorized oil or just some diesel in the top tank. do you think this would work well?


    A mixture of pyrethrin, permethrin diluted with deodorized oil might work, yes, but I would suggest you to go for one of the store-bought fogging insecticides, because these products are specifically manufactured to be used with a fogger and to kill mosquitoes and other insects.
