How to Eliminate the Gall Wasp From Our Lemon Tree
Gall wasps won't directly kill a lemon tree, but they can weaken it and make it less productive over time. Their galls look like large seed pods, or cancerous growths on your tree. The wasps lay their eggs inside. If you see these formations on your lemon tree, you should get rid of them as quickly as possible. Does this Spark an idea?

Hang bird feeders in your lemon tree to attract birds to your property. Birds are natural predators of gall wasps and will cut down on the population of adult wasps. If you think they're gone, though, keep in mind that gall wasps may overwinter in other areas and return in spring.

Tips & Warnings
Gall wasp larvae can take up to two years to mature.
Always handle wasp nests with care, as these are stinging insects.
Do not use pesticide directly on your tree, as it will not kill the wasp larvae and might damage your tree.
