I added a fistful of dead leaves. A rotting egg isn't something I want next to the back door. I've never had this problem before. Do the adults really look for food sources in the water before laying eggs?
a PhD in mosquito control told me the easiest thing to do was to put four or five pieces of dry dog food (like Kibbles) in a 5-gal bucket. That brings on a crowd of bacteria etc, which makes it attractive to mosquitoes. Of course, he know I have dogs. Cat food probably would do the same. It's worked pretty well for me. I said "Thanks Dad!"
Depending on where you live, it can be helpful to know the schedule of the local mosquito control truck. Or keep the wiggler buckets in the garage after they're started.
And once the first wiggler morphs into a pupae (bullhead aka "bouncing comma"), you have about 24 hours before critters start going airborne. But if you've kept mosquitoes before you possibly had already figured that out.
