One other thing about coffee grounds or dirt--once they're glued down, any bugs, if there were any to begin with, would be glued to death. It's also extremely unlikely that an infestation would occur after your ground cover is permanently affixed. Think about it--where would the bugs come from and why would they be attracted to a solidified mass? Seriously...
The problem is when you wet those coffee grounds with glue on the layout. You get mold with the moisture, not sealed in a container. There's no comparison.
Any microbes in the soil I used on the layout were eaten by the spiders and bugs living in my basement evey day.
