This is what I bought last year:

You mix three liquid insecticides together with 4 gallons of water in a backpack sprayer.
The other one Altosid you sprinkle into bird baths, the dogs pool, any type of standing water. It kills the larve in the water.
We’re looking more at tick control.
We do have a pond nearby but there is constant water flow through it. It is not stagnant and we have very little trouble with mosquitoes.
