Rain Barrels and Mosquitos

1 Material
2 Minutes
If you have a plain ol' barrel you are using for the collection of rain water..... do what we do.... throw a couple of .10 cent gold fish in there to eat any mosquito larvae.
These guys were put in there last summer. We brought them in over the winter and today they get to go back to their swimming hole. I must say.... our mosquito count was definitely down last summer, and.... they are an amusing conversation piece when people notice them swimming around.
The only thing you need to do is make sure to float your fish in whatever container they come in when you buy them to make sure the temperature differences don't shock them to death. I floated these guys for half the day.... only because I got busy in the garden.
Also, grab a little thing of flakes for the days there are no larvae for them.
I typically just feed them a pinch every morning when I have my coffee and walk the gardens.

    I would think the raccoons would eat the fish. I do have a rain barrel and it gets loaded with larva that likely turns into mosquitos. I have been covering it with plastic landscaping cover that has tiny holes in it. I figure the skeeters can get in but can't get back out. Has anyone had trouble with raccoons?

    These type of goldfish are carp. Mine came 10 for a dollar so I used them as 'test fish' intending to get nice ones later. In about 3 years later they were about 8-10 inches and wintered well in my iced over frozen outdoor garden ponds. Fed goldfish food maybe once a week.
