Beaverhead-Deerlodge NF to Spray for Bark Beetles at Reservoir Lake Campground

Contact(s): Leona Rodreick

     The Forest Service has scheduled the application of insecticide for September 8 and 9 at Reservoir Lake Campground on the Beaverhead-Deerlodge National Forest. The site will be closed to public use from 6 a.m. on Mon., September 8, till 6 a.m. on Wed., September 10. The need for this is driven by the current mountain pine beetle epidemic, which has heavily affected many areas throughout southwest Montana. Depending on weather, the period of closure may be extended. A Forest Service contract crew will be spraying Carbaryl to protect individual pine trees from mountain pine beetles.
     Application of insecticide began in late June with individual tree treatments in campgrounds, day-use areas and trailheads. In order to be effective the green trees must be treated late summer before the beetles fly again next summer. In addition, users may notice packets stapled to trees. These 2”x 2” packets are Verbenone and/or MCH and are used to ward off bark beetles in areas that cannot be sprayed with the Carbaryl pesticide because of being too close to water. Please leave these packets in place to protect the trees.
