Title: Wasps on live oaks from Sinton TX
Answered by: Barbara Medford

QUESTION:

Wasps on my live oak trees. What is attracting them? Does this hurt the tree?

ANSWER:

Believe it or not, wasps are considered beneficial insects. Anyone who has ever blundered into a wasp nest and paid for the mistake is not going to believe that. No doubt what you have in your live oaks are aphids. Here are a couple of previous questions about them; they have been a terrific problem in Texas this summer.

Now, read these two university websites on the aphid problem. Remember, the aphids can damage your tree, and insecticides will kill beneficials like wasps and ladybugs and leave aphid eggs safe to hatch again.
