Karen,
Add frogs. I'm serious. I accidently brought Pacific tree frogs from my greenhouse in California when we moved a couple years ago. I had 3 but only one was croaking so I assume one male and two females. They laid eggs. I brought some more eggs from California last spring for genetic diversity. Tree frogs eat aphids and ants and anything else they can get their little mouths around, even crickets. They do not eat mealy bugs.
I never see them unless I accidently wash one out of a pot and they only croak in the spring when looking for love. I don't know how many are in there but the insect problem is a non-problem so a few at least. I suspect some go out the windows in the summer but as Pacific tree frogs live in Reno also, I don't worry about them. They lay their eggs in saucers and the tadpoles live in the saucers until they turn into little tiny frogs. I will let you know how many croakers are out there in March.
This guy was sitting on the wall of my house (inside the greenhouse) in November.
