All of the permaculturists I visited since I took the PDC earlier this year
have ponds (large and small) and they've told me that the fish they keep
help to control mosquitoes. I am thinking of putting in a few tub ponds
around my house to keep guppies. Before I do this I want to check with my
learned friends on this list if they have had good results at controlling
mosquitoes with fish like guppies, or mosquito fish (gambusia, which are
more common in the southern US)? If this is really effective it would make
life much more comfortable for me here in the tropics.
