Teresa:The squiggly lines and curled leaves are an indication that your citrus trees have had a visit from citrus leafminers. Now... once you see the damage, the moth has laid its eggs, the larvae have hatched and are gone and there's no reason to use a chemical. There are parasitoid biological controls in Florida.
My lemon and grapefruit leaves are curling and it looks like a snake design on the leaves. Could you tell me what this could be. Thank you.

Leafminers like new tender foliage. It doesn't hurt the citrus tree or the fruit but can be a problem for young trees trying to leaf out. As your citrus trees get new leaves, you can spray with Bayer Advanced Fruit, Citrus, and Vegetable Insect Control. It provides from one to three months of protection from the insects. Follow the instruction label to make sure that you have the best effectiveness.
Make sure you're fertilizing your citrus on a consistant basis every three to four months with a balanced fertilizer with micro nutrients.
Leafminers can also attack ornamental plants and vegetables. Make sure that the insecticide you use is certified for home use and edible landscaping.
