For the past few weeks, some animal has been repeatedly digging up my raised garden beds. I have not seen it as it happens in the middle of the night. I wake up to big holes in the dirt and dirt outside the raised beds. I think it could be a squirrel, skunk, opossum, or a rat? Perhaps this animal is digging up and eating those big white grubs. I left the backyard light on but it doesn't seem to help. What has worked for you?
