Hey Patty. Thank you for thinking of this as a bird freak. When the water goes, so do the birds. Genetically, many things that harm one, harm both.

What kind of weeds and what are you thinking of doing with the creek bed? I haven't used rodeo before, but will look it up.

Hey there! Thanks for responding! I built the dry creek bed to deal with major storm run off. However, now the weeds want to grow (crabgrass, dandelions, etc.). I want it to look nice so I was hoping to spray something like round up that isn't harmful to fish/wildlife. Rodeo looks like it should work...
