I would be a tad unhappy!!
Seriously, I would place a few slices of potatoes or apples ( they both work equally well) right on top of the medium/next to the leaves and nearby, but leave room for a snail or slug to get underneath. You will be surprised what you find on the underside in the morning, especially if you grow outside.
In two weeks or so I will start carrying my plants back inside - it will be a chirp-fest for a couple of days!! I always move Crickets along with my plants inside!
