I had chinch bugs. my neighbor (Howard) MR YARD to us folks showed me how to check for them. Cut out both ends of a coffee can, stomp it into the effected area, fill with water, and watch those lil things swim. Then get BUSY treating, they move yard to yard.Winter fertilized early this spring and our yard has made a come back from last year. YOU LIL CHINCH BUGS GOT TO GO. Bye Bye.
