Gardening Woes

Well, many plants in our back yard have "Leaf Miners"...never had 'em before and don't know how to get rid of them.  I sprayed an insecticidal soap on them this evening and I've been picking off the leaves where the pesky critters "made their mark."  If you know how to rid your garden of them, please let me know.  If you've never seem them, they leave squiggly lines where they've burrowed on your leaves.  Bummer ; (
