the world's most perfect fertilizer + pesticide is epsom salt. This is so true- every other week- 1 gallon of water, 1 TBSP of miracle grow and 3 TBSP of epsom salt- I promise a great garden all season. Hmmm, I really should try this.
Keep flies AWAY from outdoor parties! Use lavender oil on a sponge & put it inside a can with a lid 24hrs prior the party. Open can & enjoy your food w/out flies flying all over your food. You could make a few and spread them along your food display.
