We have a lettuce bed that recives no pestisides of any kind. Neither does our yard.
I have one kid of lettuce that attracts lettuce aphids. A few times a week I'll pick two small leaves with 10-15 aphids , the aphids are about as big as ( , ) that comma, on the underside and float them in my two little guys tanks. They just love them and clean the leaf off in a few minutes. As soon as I started to do that they now greet me everytime I go hear their thank with expressions of "OK Mom, where's the buffet?".
They never look bloated and seem to perk up when their done with their snack is done. Does anyone forsee a problem with that?
