Anytime I have standing water, as in the rain barrel when its not raining, I want to use mosquito dunks or something similar to kill larvae. I don't think screening alone will keep all adult mosquitos out and we know what they do when they're together, if you catch my drift. But maybe it's overkill. I just always keep a lot of the dunks around so it's easy to throw one in. A lot easier than putting the bungee cord around it to keep the screen on. Maybe I could look into using liquid Bti. Might be cheaper in the long run. Don't know. Nevertheless, the screen helps keep debris out. Would it keep mosquitos out? Hard to say. Maybe I'm just doing a 'belt and suspenders' trip.
Occasionally there have been classes in which participants learn to make their own rain barrels. I always think that I'll go. But the timing never seems to work out for me.
Anyway, it's been a quick and easy and inexpensive way to save at least some rainwater. I'm sure it could be improved on.
