I am going to try building a little pool in back by my garden to encourage my little bug eating friends to multiply.

I checked at the local farm store and they have small heavy plastic rubbermade black 50 gal tubs for a about $30, same size as those mini pond inserts, but half the cost. I am also going to add a little solar sprinkler pump to keep water moving. the whole thing should cost less than $50.00.

Any suggestions?
