Thanks guys. Our some experts at our local university say to only treat if there are problems. I've really considered offering at least one grub app a year. I see lots of guys advertising the grub app as "grub and mole control." I've always thought that earth worms were the food of choice. Has anyone seed a decrease in mole or vole activity when adding a grub app? How many apps do you do? One in spring at egg hatch time(June here) is a given, but do you do a follow up curative app later in the year? What is the product of choice for that? Dylox or something different?
