Koala, I read where you should juice the lemons when ripe, put the juice into ice trays and freeze. Then put the frozen cubes in a ziploc bag and keep frozen till needed. Great for lemonaide, margaritas, marinating meats/fish, cleaning cutting-boards, etc.

My Bug-man also suggested mixing lemon juice with water and putting it in a spray bottle. Spray around (not on) houseplants that have been outdoors to kill the little gnats, ants and other bugs that made a home there.

You sure are lucky to have such a productive tree!
