Bananas? I've never tried that. I have caught them by using traps with two doors and leaving both doors open - They walk through the trap because it looks easier than walking around.
I baited it with a piece of fish, two shrimp tails and a pluot pit. Wonder if I should have added a starch?
I've had the koi for 3 years - my daughter points out that they probably came to the surface and said eat me (hand fed fish). It didn't get my turtle - I've had him for 15 years. I do worry he will be back to try again and, as this was a daytime raid, I also worry about my dog. A raccoon would probably out weigh him but he's a terrier and thinks he's really big.
