Last summer bore beetles wiped out half the pines in my yard. (1 acre.).Since the Florida drought is over and steady rains are back, and the pines are not as stressed as last year, will my remaining loblolly pines fight off the bore beetles naturally or do I have to spray with something. And if I spray is it true the beetles are only on the trunk of the tree. Last but not least, what do I spray with? Thanks from Central Florida, Roger
Like many living forms, insects reach a peak population, do major damage, and then suddenly die back to a small population which takes seasons to grow large again. The stress on the trees due to the drought combined with the population explosion of the beetles contributed to the tree loss. That population was increasing, doing hidden damage for years. The best control is to rid the area of tainted wood from the dead trees which is harboring the pest. Chec
k with local exterminators regarding a pesticide control.
