I had a minor mole problem in the front of my yard. I live in a sub development with kids and pets so not wanting to use toxic chemicals or lethal force unless absolutely necessary I gave this a try. I applied a heavy soaking to a 6' perimeter around my property and we have had no activity since, before using this stuff I was seeing new mole hills every few days. It was very easy to apply with the hose and made no mess. I expected an odor but it wasn't noticeable and was completely gone in 10 mins. I have no idea where the mole(s) went but I haven't seen them on my property. This would certainly be my first attempt to remove a future infestation. My experience was with moles only, I don't know how gophers respond to this stuff.
