To prevent future groundhog infestations, consider implementing exclusion measures, such as wire mesh around the base of the shed and extended underground to stop groundhogs from burrowing back in. Ensure there are no openings in the shed's foundation that could be used as an entry point.
'Ideally, you would move your shed, re-grade the ground under it, and add a layer of heavy stones, about one-inch diameter,' says Ryan Farley, CEO of LawnStarter. 'This will remove any empty spaces under the structure and make it hard to dig out a new one. If you can't manage all this, you can block holes with large stones or chicken wire.'
