I live in a housing estate in the tropics. The "neighbours" tend to call the council in to my property. I got fined once because they found larvae in some 5-gallon bucket I use as a rain barrel despite the net across the mouth preventing mosquitoes from flying out.
In the latest notice for action, they specifically mention trees and bushes that collect water. I examine my banana plants and indeed after a rain, there is water collected at the crown. Bummer. I rectify this by pouring in fine sand to displace even that little bit of water.
BUT nobody addresses the elephant in the room. All our houses have septic tanks. If you go to the WHO website, it is the number one source of mosquitoes.
Anyone know how to deal with this? We can't cap the vent pipe because it is there for some reason - to disperse explosive gases perhaps?
I mentioned this in my letter to the council. Maybe experiment with flushing dry ice chunks down the toilet and suffocate the larvae but they have not gotten back to me.
