Question
wet truck
one of the 13 Maples i planted 2 years ago had water running down the truck today and the others did not. what is causing these small holes..
AnswerLooks like wood pecker holes. Maples have a thin bark so it does not take much damage for them to exude sap. The bird is either going after an insect in the bark OR is one of the sap suckers woodpeckers that makes hole and when the tree exudes sap insects feed on the sap and the bird returns to eat the insects. I would spray the areas with Merit insecticide. This will kill any insect in the bark and also kill or prevent any insect attracted to the sap and the woodpecker will not return since it has nothing to eat.
