Bark Beetle Prevention: Pine and Fir Trees may be protected starting in the Spring with a one time, season long preventative spray application on the trunks of trees. Government research supports a “97% control for one year”. Some variables that work against the trees are: drought conditions, inhibition or diversion of water from structures and cuts in grade from septic systems and driveways, or soil compaction from vehicles. We are the most experienced and best equipped Bark Beetle Prevention company in the Sierras! We also provide foliar sprays to control Cedar Bark Beetles, Cypress Tip Boring Beetles, and other target pests associated with different trees. Please feel free to call us for a free estimate!
