Well, only one thing I am doing in this case which is putting enough
bacteria but not filling the plates by it. I seed the bacteria as a
small spot in the middle. In this case, if the worm is wild type from the
side of smelling the food, it will come back to the food soon. This will
not give it a chance to make a mistake of curiously climp up the very
near wall to its wall.
If it will not work, you might use highly osmotic solution
surrounding the spot of the bacteria to force the worms avoiding crossing
