How can we adoid leaf miner damage on tomato plants?
Re: garden pests
If it is only a little damage to the plant remove the leaf or squish the bug inside the leaf. It is difficult to treat the plant once it is infested the leaf will protect the insect. There are some pheromone traps to attract the mature egg-laying leaf miners. Beneficial insects, like ladybugs or parasitic wasps with attack leaf miners. Remove any debris around the plants for the leaf miner to hid in. If you need to spray contact you county extension service for recommendations and timing for your area.
