How do you treat for something that is making tunnels under the lawn? Maybe moles? Im pretty sure I have zoysia. One side of my lawn has been almost destroyed.
You have a difficult problem if you have moles, an insectivore which is among the most primitive of mammals with a voracious appetite and high metabolism. The eastern mole has one litter of 2 to 5 young, born in early springtime, per year. Moles live about three years, and 1 acre of turf will support two or three moles at a time. They search among plant roots (preferring the upper 12 inches of loose, well-drained soil) for earthworms, mole crickets, beetle larvae (white grubs) and ants. The damage to they do is almost entirely cosmetic. Moles don’t eat roots. However, excessive drying of roots as a result of their foraging may kill grass. The simple control is to eliminate the food source (insects and earthworms). But insecticide treatment of an area may cause moles to tunnel more to seek out a diminishing food supply.
