Oil for mosquito control
I'm setting up a gravity fed drip system in a location without city or well water or electricity.
I have 4 55-gallon drums with closed tops. We can use cheese cloth to exclude mosquitos out of these drums. I also have a very large 100-200 gallon container that will be the main source for the irrigation. It has a large open top that will be expensive/difficult to cover.
I was thinking of putting a layer of oil on top of the water in the large tank. What type of oil is best?
Also since it is possible that all of the water could be drained sending the oil through the drip lines and onto the plants will vegetable on the soil be a problem?
Will the oil even work?
I'd also like to know about how long it will take before the oil degrades.
Thank you for yor help. If you need any more information let me know.
