Do You Have Questions About Mountain Pine Beetles?

Are the Pine Beetles diminishing?
It would be very nice to think that their cycle is ending. However, we talk to the Forest Service and other people all over the Western US. Montana was particularly hard-hit last year. The Eastern Slope of Colorado is getting worse, and Wyoming is seeing more. It is an unfortunate fact that until the trees are gone or the weather gets colder, the Beetles are happy and flourishing.

It is easy to relax. Don't let up just because you think your little patch of heaven is clear. An ounce of prevention is still worth a TON of cure.

How many Mountain Pine Beetles does it take to kill my tree?
Research shows that it takes about 40 successful beetles to actually kill a tree. The problem is that you can't tell if each of 40 pitch tubes were successful. The second problem is that ANY successful beetles will multiply in the tree, letting loose another horde the next season which will probably be successful in killing the current tree AND attacking adjacent trees. (One beetle can produce up to 60 new beetles next season)

Which trees are most susceptible to Mountain Pine Beetle Attack?
Lodgepole Pine, White Pine, Ponerosa Pine, and Limber Pine are the most common, although several other species are at risk. Given the choice, Mountain Pine Beetles choose the largest diameter trees. When those are gone, they will attack smaller trees.

They also love damaged trees. If you have trees in a construction site or damaged by heavy equipment, the beetles will sense their distress and attack them because they are less able to protect themselves.

How do I tell a pine tree from and Douglas Fir Tree?
There is an old adage that you can shake hands with a fir tree but not a spruce tree. If the needles are very uncomfortable to touch, it is not a Douglas Fir. However, the difference between a pine and a fir is a little more detailed.

You must look at the needles. If the tree is a Douglas Fir tree the needles will be attached to the branch one at a time, and they will be short. If it is a pine tree, the needles will be attached in pods of two or more attached to the branch from one base and much longer needles. Pines are susceptible to Mountain Pine Beetles. Douglas Firs are susceptible to Douglas Fir Beetles. The preventative treatments are different as is the timing of prevention.

Can I save a tree that has been attacked?
Almost never. If the beetles don't get it the blue stain fungus that they introduce into it will eventually kill it. It is best to take it out now and minimize its risk of killing adjacent trees.

Can Mountain Pine Beetles hatch out of dead trees - trees that have been cut down?
YES! If a tree is infested, its chances of survival are minimal at best. You must cut it down. But that is not the end of the story. You must get rid of the downed wood or the beetles will live happily on in the lifeless trunk, using stored nutrients, until the Spring or summer. Then they will develop and fly as usual.

Can I cut Pine Beetle infested trees in the Fall and get rid of them in the Spring?
Yes. When time or labor is short you can cut trees infested this year in the Fall before the snow. They can remain on the ground until Spring. They can frequently be burned during a snowy Spring without risk to the forest. Or they can be bucked and hauled to a burner before the next hatching time in July.

Is BeetleBlock still the best treatment, or are others gaining credibility?
Injecting trees has been tried and rejected. Spraying with poisons is frequently done, but has very bad side affects that often off-set the benefits. Verbenone is STILL the best treatment. It was developed specifically for Mountain Pine Beetles. While it is not 100% effective, it continues to be the treatment of choice to prevent them, and the price has finally become reasonable.

Is BeetleBlock dangerous for the my pets or animals in the forest?
It is very targeted to the specific species it was designed to deter. It will not affect other species - not even other beetles. It doesn't even actually KILL the Mountain Pine Beetles.

What happens to beetles that do not land on MY trees? Do they go to my neighbor's trees?
Don't worry that you are infecting your neighbor's property. While some beetles deterred from your trees may land on others on adjacent property, they have a limited amount of energy to fly in search of a suitable tree. Many will die of exhaustion in unsuccessful transit. During their search, they will also become great meals for birds.

It would, of course, be a good idea for your neighbor to protect his trees as well. Orders of Verbenone can be combined to get more discounts to make it even less expensive for a group than for an individual.

Do high winds blow the beetles away?
Prevailing winds certainly affect the direction the beetles move. Winds also affect the direction of the plume of Verbenone beetle repellent. Use them to your advantage when placing the BeetleBlock pouches. The pouch will protect the trees directly around it and in the direction the wind takes it.

Should I spray with an insecticide AND use Verbenone BeetleBlock?
Of course, only you can decide if you want a toxic chemical on your trees or near your property. Some pesticides have shown success in killing attacking beetles before they reach the egg-laying cavity. However, as satisfying as killing beetles can be, these types of products (even the mildest of them) affect other species. Dead, poisoned beetles are not good fodder for birds or fish. The drainage and run-off from chemicals sprayed on trees affects the water table as well.

Studies show that Verbenone alone is as effective as these sprays without the side effects.

What about Beetle Traps? I see them at the log burners all the time.
Beetle traps are a two edged sword. Because the beetles are attracted to them you would think them the perfect answer: Gather them all into the trap and be done with it. Unfortunately, Mountain Pine Beetles have a very poorly developed sense of direction. Certainly, some hit the trap. But many will miss the trap and hit nearby unprotected trees. If those trees are susceptible pines it could be devastating.

There is some logic to using a pine beetle trap in a large aspen grove. If you have a large grove of trees that are NOT susceptible to beetles but are surrounded by trees that are at risk, the trap might be a good idea. It could pull the beetles from the infested area into an area where they will be unsuccessful.

ALWAYS ask a forest professional if this is a good plan for your particular property before taking the risk.

Will Mountain Pine Beetles damage my Log Cabin?
No, pine beetles need a LIVE tree in order to reproduce. They neither seek out nor reproduce in dead or dried logs. If you happen to bring live pine beetles into your house on stored firewood, vacuum them with the vacuum cleaner and spray the bag with an insect killer before discarding.

Why Verbenone is the treatment of choice.

Verbenone is the treatment of choice for property owners who want to protect their high value trees and acreage but don't want to risk wildlife and run-off of contaminants. It is tried and true - tested for many years in the forests of Idaho, Montana, Wyoming, Colorado, British Columbia - all up and down the Rockies. The US Forest Service and the National Park Services have purchased thousands of treatments and continue to purchase more each year.

The pheromone comes in tiny pouches that you tack to the trunk of the susceptible tree in the early summer. It tricks the beetles into continuing to fly, looking for more fruitful acreage than yours. Many will die before finding suitable habitats.

It's easy and effective. In the past it has cost more than spraying poisons. Not now! Our volume purchasing power has brought the prices down to an all-time low!

Now, Verbenone is easy. Effective. AND less expensive than poison! Buy it Here
