Moles...How to get rid of them??
I don't think the geese will be harmed by the grub pesticide. Its in granular form and should not leech into the pond.
My neighbors and I have had great success in controlling moles using spear type traps. By success I mean 7 moles last year and 3 this year. If this is the type you have used without success, please check how you are setting them. We didn't catch anything until we got the traps figured out.
