What management techniques are used to control beetles?
In addition to harvesting at the leading edges of what is known as “green attack,” a variety of other techniques can be used to manage infestations on a smaller scale. These techniques include: • Pheromone baiting – luring beetles into trees that have been ‘baited’ with a synthetic hormone that mimics the scent of a female beetle. Beetles can then be contained in a single area, where they can more easily be destroyed. • Sanitation harvesting – removing single infested trees to control the spread of beetle populations to other areas. • Snip and skid – removing groups of infested trees that are scattered over a large area. • Controlled, or mosaic, burns – burning an area where infested trees are concentrated, to reduce high beetle infestations in the area or to help reduce the fire hazard in an area. • Fall and burn – cutting (felling) and burning beetle-infested trees to prevent the spread of beetle populations to other areas. This is usually done in winter, to reduce the risk of starti
