pine beetles,about trees natural defense


Question
How long will it take after a drought for pine trees to start producing enough sap to defend against beetles.   Please help me!

Answer
Toni,

Pine trees produce sap throughout their life times, even droughts.  Droughts weaken trees and allow invasion of insects pests.  Once a weakened tree has bark beetle there is not much to do.  A certified arborist may be able to suggest remedies.
