How do you protect bark beetle trees? Avoid injuries to roots and trunks. Remove any bark beetle-infested trees to prevent further infestation of other trees and shrubs. Infested trees which are removed should be taken to mills, grinding sites or covered with clear 6 mil plastic for not less than six months to prevent the spread of the beetle.
How do you fight bark beetles? The most common method of protecting individual trees from bark beetle attack is to spray the tree bole with insecticides registered for this use (e.g., with carbaryl, or the pyrethroids bifenthrin or permethrin).
