As you have found out, getting rid of the grubs doesn’t automatically get rid of the moles since they eat earthworms as well. You should apply MoleMax now and then in September then every September so you don’t have therm every spring. More on Mole control HERE.
Grub treatment should be applied in July followed immediately by getting watered in with 1″ of water…a very heavy watering. If it isn’t watered in, it doesn’t work…this is where most people screw it up. Don’t think rain or walking around spraying the lawn is enough…it isn’t. More on grub control HERE.
