Help! there are holes on the top soil of almost all of my houseplants in my first floor living areas. The openings are about the size of a quarter and looks as though something has burrowed down into them. Have tried digging through to find out what, soaked with water, etc. but they eventually appear again. Any idea what this could be? Do mice do this?

I want to know when you find out becasue I have the same problem

they have been known to do this.eat leaves and dig holes in flower pots.

well I have lived here for 4 years and had the same plants for the same amount of time but never have I seen this until this year. We get field mice all the time and have to put traps out but had not seen any in my plants.
