Lubastic: I'm morally ready for everything in the sense of a puppy, I hope in one puppy's diary read a recipe for the remedy for flies: you need to pour water into a bag transparent on the lightning, put glowing coins, press out lemon juice and add something else there. Close and hang over the door. The coins in the bag blind the flies, and they can’t see where to fly. The lemon juice does not allow the water to melt.
A million words of thanks.
