The only way with your house will be to check the entrance for signs of traffic to know if it’s in use or not. I place some straw in the entrance and see if it gets moved. They should have got up in April but there’s no guarantee that they’re not still hibernating, wait til late April/early May depending on the weather.
In checking the entrance for usage be aware that the hogs know you’re doing it and they WILL wind you up! I normally leave the straw in place for at least 3 nights before deciding to clean it out and you can guarantee that they’ll wait til the 3rd night before disturbing it. This year they dragged this out for two whole weeks before I was certain! They’re evil like that.
