What causes oak gall?
Galls on trees are caused by insects laying eggs inside or feeding on the branches of leaves of trees and other plants. This usually occurs in the spring. The galls, or tumor-like growths, are produced by the tree in response to chemicals injected into it by an adult or larval gall-making insect.
Why are wasps attracted to my oak tree?
These wasps lay their eggs in the terminal growths of dormant buds of oak trees, which is the resulting gall you see on the branches of your oak tree. However, the gall exudes honeydew, and this is what attracts other wasps, which are a nuisance to us.
How can gallbladder wasps be prevented?
