I live in Florida & have several large long needle pine trees in the yard. Just moved here in October 2014....
Area was totally woods. they cleared the land to build my house. The remaining pine trees have the holes bored thru the pine bark, with lose pine bark falling off. Can I have any success in treating with an insecticide?
Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations. Healthy trees can be protected before the beetles attack by topically spraying them with a product calledPermethrin SFR. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations.
