@Ferdinand, we know when the foxes might well be poking around in our garden: the scent of mint wafts towards our house: if the dogs also bark, we can be certain.  While appreciating the offer, locally mint is abundant, not to say a weed. Now lemon or apple mint, well that would be nice ... I need a good dose of mint now to calm the nerves: Sketchup has frazzled me all damn day. Trying to squeeze quarts into pint pots, while not fully conversant with the software. Arggghhhh.

 

Cross ventilation and opening windows (tilt and turn) it seems to me will be essential. With wafts of mint on the breeze, hopefully.

 

I find that I don't need enough mint that I can actually smell it.
