Thanks Gary, I heard that on the ABC News Radio this morning, the vaccine can't come soon enough

As is well known Mossies like water troughs and the like, Is there any stuff

that can be put in water containers that are lying around that stops mossies breeding?
I have a 200ltr drum and an old bath which catches rain water for the garden which gets plenty of mossie tidlers in them.
I know that you can put Kero in the water but then the birds can't have a bath in the water.

Any other suggestions.
