Title: Oaks emitting substance in Lakeway TX
Answered by: Barbara Medford
QUESTION:
We have two large oak trees in our yard that are emitting a clear, very sticky, non-fragrant substance. The leaves are beginning to be covered as is our deck. Bees are now attracted and I am worried how long this will last and if I should be treating the tree in any way. Do you have any idea what this could be?ANSWER:
One word: Aphids. They are unusually bad this year, and we have answered many questions on them. From the University of California Integrated Pest Management Program, here is an article on managing aphid infestations.
