Contrary to popular belief, moles prefer earthworm to grubs. Grubs are mainly food that skunks search for during the evening and nighttime. For moles, use Talperid. This spring we had such a problem with them. Use about 120 of the bait over a month or so. Moles have huge colonies but you've got to stay with them. An application of Merit in the spring is good, but if already a problem then Dylox would be your best defense. It may take a couple of application but does work. For you Talperid, check online. Homedepot has a product called Tomcat with the same AI in it, but it is something like $19/6 worms. Talperid from domyownpestcontrol.com is $40/20 baits.
We all are merely gleaners from the masters who were here before us.
