The Mountain Pine Beetle is the most important pine killing insect in western North America. Outbreaks of infestation destroy Lodgepole and Ponderosa pines. The life-cycle of the beetle is one year. To kill these beetles, there would have to be a severe freeze in early fall or spring while the insect was in the larval or pupal stage.

Is a pine beetle bite harmful?
When the bite happens, the beetle releases a chemical substance that can cause the skin to blister. The blister usually heals within a few days and causes no permanent damage. A bite from this type of beetle may cause considerable pain that could last up to a day or two.
Do pine beetles have a predator?
The mountain pine beetle (MPB) has many natural predators including insects, parasitoids and woodpeckers. However, these enemies do not have sufficient impact to effectively control new or outbreak populations. When a beetle population is low, healthy trees are able to defend and suppress an attack by producing a toxic resin.
How do you get rid of pine beetles?
The only treatment that can be applied to the tree is preventative. This will protect the tree by killing the beetles before they infest the tree. Insecticides containing the active ingredients permethrin or carbaryl and labeled for bark beetle control, should be done by early June to protect trees from MPB.
What causes pine beetle infestation?
A number of factors—drought, tree diseases, and overcrowding—can make trees more vulnerable to beetle attacks, and in some cases bark beetles may infest weak- ened trees already doomed to die.
How long does it take pine beetles to kill a tree?
Bark beetles tunnel under bark, cutting off the tree's supply of food and water needed to survive. Bark beetles can kill a tree in as little as two to four weeks during warmer months.

Sanitation. Removing and destroying infested trees help protect neighboring trees that are still healthy. Burning, or chipping and burying the trees with borers inside, will kill the borers before they become adults and can walk, crawl, or fly to nearby healthy trees. Sanitation is most effective between Oct.
What do you spray pine beetles with?
Carbaryl (Sevin SL and XLR and others) and Permethrin (Astro, Dragnet and others) and bifenthrin (Onyx) are registered for use for preventatively spraying for pine beetle. Use only formulations of insecticides that are labeled for use to protect trees from bark beetle attack.
Can a pine beetle hurt a tree?
Large populations of mountain pine beetles can be determined by the presence of woodpeckers, which feed on developing larvae under the bark, punching holes into thin-barked trees like the whitebark pine. Within eight to 10 months of a successful attack, the tree will fade and eventually die.
Does cold weather kill pine beetles?
Cold weather can kill the mountain pine beetle. The beetle's eggs and larvae are the most susceptible to freezing temperatures. Windchill affects mountain pine beetles, but usually is not sustained enough to increase winter mortality significantly.
What do you do with a beetle infested tree?
We recommend first using a contact insecticide such as Sylo Insecticide to the tree trunk, limbs, and bark to prevent any adult Bark Beetles from penetrating the tree bark. This is a pyrethroid that delivers a quick knockdown of insects on trees.
What do you do if a beetle kills a tree?
After a tree has been felled, make sure to cut the stump as close to the ground as possible or have it ground down as this material can also serve as spruce beetle habitat. If you do not intend to keep or use the infested material, several communities have woodlots associated with solid waste disposal.
Can you save a tree with borers?
Most tree borers are the larval stages of certain beetles and moths, others do damage as adults such as the bark beetle. No matter the type, tree borers need to be eliminated quickly to save your infested tree or else you may have to remove the tree entirely.

How to treat mountain pine beetles?
Solar treatments can be used to reduce mountain pine beetle populations in small infested stands. These treatments involve felling infested trees and stacking cut logs in an area with full sun before covering them with clear plastic.

How to treat southern pine beetles?
Spraying after a tree is infested with southern pine beetles has little practical effect. Little can be done as rescue treatments. Pines should be kept vigorous by mulching and watering in extremely dry weather (but NO fertilizer!). Don't injure the bark and avoid excessive grading around the roots or compaction of soil. Cut infested trees down just as soon as southern pine beetles are detected and debark or remove the the trees immediately. The application of protective sprays of pyrethroid insecticides for living trees is expensive but may be considered for valuable specimen trees.

Can beetles find sap?
A normal healthy tree will emit or release some sap that can attract beetles. When a tree is injured and sap runs freely and the odds that beetles find the tree are greatly increased. Once found, beetles will penetrate the bark and then begin excavating tunnels between the bark and the wood of the tree.
