I have several clients with a St. Aug problem. The first indication is the areas look like they are drying out, but we've had an abudance of rain lately. Some places appear to have some mole activity, but whole sections will come up, like peeling back a carpet. This is standard grub symptoms, but I haven't found any and thought it would be too early for them now. The dirt underneath is very loose, almost like it has been tilled. There are some sections where I can stick my hand through what seems like a tunnel, but maybe that is where the moles have been. Any thoughts?
