Lawn insects

Asked June 16, 2016, 12:45 PM EDT

A gentleman came into our office today with this lawn problem. He has white spots all around his lawn, about 10 all together. The spots range from 6" in diameter to roughly 12" in diameter. He "knows" it's not white grubs. When he walks by the spots little white moths fly up and around. Would you have any idea what type of moth is doing this and what he can used to get rid of them. I've attached two pictures of the lawn damage. He said the moths are too tiny to try and catch one to have it identified.
