Thanks for the info!

I've used the Ortho products like this very successfully around my yard but I'm really spooked about using them so close to my water. Of course, there's no need for me to let any of the chemical actually touch my water but...it's still so close that any kind of accidental spill would get into the water before I could react.

If you're too scared to throw that bait where the fish are, why did you tie it on?
