I think there are other better options...

But what the county told us for soccer fields .... Have the coaches bring bubblaciius bubble gum. The idea is to be as sweet as possible. Chew it a few bites to loosen the sugars. Then put the wad in the hole.

They evidently like the sugars but get the gum stuck in their mouth can can't clear it. Go deep in burrow and evidently starve.
