What are my options for controlling black turpentine beetle infestations?
The black turpentine beetle is the only pine bark beetle that is confined to the lower six to ten feet of tree trunk. Except in extreme situations, the beetles do not mass attack trees as do the Ips and southern pine beetles. Rather, they tend to build up over a period of weeks thus allowing time for control by homeowners and landowners. Spraying the lower ten feet of trunk with a recommended insecticide can effectively control black turpentine beetles. Do I need to remove trees that are already dead? (Those with brown needles or no needles.) Dead trees from which bark beetles have emerged may harbor beneficial insects such as the checkered beetle. If dead trees are no threat to property, humans, or pets, they can be left standing to provide homes for checkered beetles and cavity nesting birds. Be sure dead trees are away from property lines, powerlines, houses, cars and children’s play areas. Stay away from dead trees on windy days as they often lose branches and upper trunk sections
