We have the same problem at Burlington. What we do is have a mixture of seeds and sand ready at all times and fill the holes as they occur and fill the holes level to the playing surface. I don’t believe that you could get rid of them that easily. I know it a problem but it is against the law to trap them. So we have to co-exist.
Hope this helps.
Thank you Charlie. I hope you know how much I appreciate your continued support on all matters "green "
