Hi Ajmartin
Good news that you have hedgehogs in the garden! I imagine that if they were involved in courtship activities under the tarp that they won’t be there any longer.
Brilliant that you are getting a hog house. If the hogs, or one hog, is still under the tarp, I would place the hog house fairly near and hope that it moves into it (as you suggested). As long as there is a suitable location nearby. But give them a chance to move without removing the tarp. If a hog has built a nest under the tarp, you shouldn’t remove it. If you put a small amount of bedding into the house it might give a hog the idea to move in, but place more suitable materials nearby – i.e. long grasses, medium sized leaves, etc. Many hogs like to do their own interior decorations!
I wouldn’t put food into the hog house, if you are hoping for it to be used for nesting. (Some people use hog houses only for placing supplementary food in, but that’s a bit different).
Good luck. Hope it all ends up well.
