TIL a really cool, safe method for GROUNDHOG DETECTION!
If you have a hole that you think a groundhog might be living in (and we have several at the new house), place a light object over it.
Something that a groundhog could move and something you'll notice if it's been moved.
We trimmings from a tree that was scraping the house.
And now? WE WAIT.
