George from Merritt, North Carolina writes
There are hundreds of these mounds of loose dirt about an inch in diameter. These are mostly along a stone retaining wall but some are elsewhere in the yard. We had these several years ago and you recommended something we had already purchased from you for mosquito control. This is a much larger infestation however. If I remember correctly, it looks like a cricket.
We would recommend contacting your local extension office. They will be able to properly identify a pest that is destroying your lawn. We would be happy to assist you with any kind of products once we know exactly what the pest is.
