Kate - Thanks for the info about removing slug slime.
Maybe I should consider getting a few pet ducks!
I already have the rodent (roof rat) problem. Knocked down a nest today that had babies in it. I put them in the vacant lot next door. They won't survive without mom. The mother rat climbed up even higher in the tree to another nest which I couldn't reach. Darn rats!!!
Cindy - I wished I had garter snakes here. I do have larger indigo snakes. I like snakes. They only bother me (and I them) when we unexpectedly bump into each other. Then we both freeze and head in the opposite direction! But they do eat the younger (smaller) rats. Which is A-OK by me!
We have tree frogs, but they are not the good kind to have. These are huge Cuban Tree Frogs that are non-natives and very invasive. They have eaten all the native tree frogs and toads.
