Reminds me of the time we had ants in the house and they decided to try to build a nest in my hood. Needless to say I knocked it down into the water and found out that my stock likes the new crunchy floating pellets.
If it's free and varied from what they normally eat you can't go wrong. I don't spray my house b/c I usually don't get bugs and when one appears it is food. Even my wife has gotten good at throwing whatever in.
