Verbenone - the Newest Tool in the FightPrecious Pines provide beauty. But they also perform a lot of other duties such as hiding this privy. These Ponderosas are at slightly lower risk than most lodge pole pine forests because this forest is thinned dramatically, a good practice to naturally protect the trees. |

BeetleBlock Verbenone Pine Beetle Pouches  |
Verbenone Pine Beetle Repellent helps protect your high-value pine trees.
The Pine Beetle is the most destructive forest pest in North America. The Canadian Forest Service describes the current pine beetle epidemic as the largest insect infestation in North American history.Mountain Pine Beetles have a one year life cycle. In late summer (usually July-Aug in Rocky Mountain States) the newly hatched adults leave the tree of their metomorphosis, seeking out larger trees (usually over 13" diameter if possible) in the surrounding area. (In areas with heavy infestation, beetle hatchlings may take even smaller trees as pressure to get ANY tree increases). When the adults arrive, they begin tunneling under the bark, lay eggs, which turn to larvae and live through the winter to produce more egg-laying adults to attack more trees.
Colorado State University Extension services estimates that one infested tree will kill at least two and possibly more trees. Thus the exponential devastation occurs.
With the exception of the actual beetle images, all pictures on this site are taken at or near our property near Estes Park, Colorado. It is our pride and joy - our sanctuary.
We, personally, have chosen Verbenone above all other products to protect our own precious trees and the fantastic wildlife that depend on them.
Verbenone and how it works.
Beetles and other insects communicate using pheromones. Verbenone - a synthetic pheromone treatment for high value pine trees - replicates the beetle pheromone, sending a message that the tree is full and that the food supply is insufficient for additional beetles. Arriving beetles receive the "message" that they should look elsewhere for a suitable host.
- Verbenone helps control:
- Mountain Pine Beetle; Dendractonus ponderosae
- Pine Engraver - Ips pini (only partially successful)
- Northern Spruce Engraver - Ips perturbatus (only partially successful)
- California Five-spined Ips - Ips paraconfusus (only partially successful)
- And can be used on:
- Lodgepole Pine
- Ponderosa Pine
- Whitebark Pine
- Western White Pine
- Southwestern White Pine
- Limber Pine and other susceptible pine species.
Does Verbenone really work?
Verbenone has been used as part of integrated pest management programs (IPM) for more than a decade. Many studies show that areas treated with Verbenone, as part of an IPM program, fare significantly better than those that are not. Commercially used in 2007 in MT, WY, ID by Forest Service, State Agencies, Recreation Areas, Home Owner's Asssociatons in high value recreational or private land holdings.
How safe is Verbenone?
Verbenone is environmentally safe and non-toxic to humans, pets, birds, and even the beetles themselves. Registered by EPA and most Rocky Mountain States. All pheromones in controlled release dispensers are approved organic by USDA/NOP. It is user and Eco-Friendly. Unlike the insecticides approved for Mt. Pine Beetle control,Verbenone does not kill bees, beneficial insects, aquatic organisms. Not restricted use. Always follow label instructions.
How to use Verbenone:
Easy to use controlled release dispenser that is hung on individual specimen trees or placed in a grid pattern when wanting to protect acreage. Placed approx 6-7' high on the north face of the tree (where there is more shade) or downwind of prevailing breezes so that the "plume" of pheromone will waft in the direction of the trees being protected. See detailed instructions and ingredients HERE.
How to use Contech Verbenone:
For Mountain Pine Beetles, it is our recommendaton that you staple or nail the first Verbenone pouch 7 - 10 feet high (2m) on the north face of the tree just prior to beetle flight season (April to Aug, depending upon location). Attach the second pouch just prior to PEAK flight (usually July - August in the northern Rockies).
* How to use BeetleBlock Verbenone:
For Mountain Pine Beetles, recommended one application. Nail the BeetleBlock pouch 7 - 10 feet high (2m) on the north face of the tree just prior to beetle flight season (apply June 1 - July 1 in Mountain States).
In a study produced by the USDA Forerst Service in Missoula Montana in 2007, it was found that the effeciiveness longevity for BeetleBlock Verbenone was higher and longer than the Contech Verbenone. Between May 19 and September 2007 at a mean temperature between 75.4 and 76.8 degrees, the BeetleBlock pouches lasted 103 days in sun and 131 days in shade while the Contech product only lasted approximately 75 days.. This duration of effectiveness probably accounts for Contech's instructions to treat the trees twice between April and September while BeetleBlock recommends only one application during peak flight time between end May and end June.
For protecting stands of trees, use at least one pouch every 25 feet in a perimeter surrounding the stand. Also place a Verbenone pouch on the North side of the largest tree. By encircling the stand and boosting the repellent on the most desirable tree, the pouches can be used in more economical fashion and may help to protect more than the one tree per pouch.
If your trees may be attacked from unattended neighboring property, try to create a Verbenone barrier on trees on the windward side of your trees (as described above) in a perimeter no more than 25 feet apart and boosting the protection on your largest trees.
Verbenone is prescribed as part of a multi-faceted approach to mountain pine beetle management. No single treatment can totally prevent attacks. Additionally, preventative measures will need to be repeated each year or each flight season in areas with more than one season annually.
If used for Ips Beetles
the season is longer, as two to four generations of these beetles usually develop per year. Verbenone is only partially effective against ips beetles. The best combination treatment for ips pini is a combination of verbenone and ipsenol. However, no commercially developed application combination has been developed at this time.
Overwintering ips beetles begin emerging in spring as soon as daytime temperatures consistently reach 50 F to 60 F. However, timing can be difficult to determine since ips beetles can have multiple, overlapping generations and life cycles. Use earlier and repeatedly through October.) The ABSOLUTE best practice to prevent ips beetles is to remove all slash, boughs, and limbs, (which attract ips beetles) immediately.
See "Preventative Spraying Techniques to Control Mountain Pine Beetles" Studies have shown that during epidemic conditions, the pressure from beetle populations who must go SOMEWHERE (even if conditions are not optimum for them) may reduce the effectiveness of all treatments. Given the "find a tree of any size or perish" imperative that emerging pine beetles face, they may habituate to both chemicals and pheromones. However, we still have a few years to work on the problem in areas that are not yet overrun. That time may give just the breather necessary to let nature begin to draw back the danger or for other management techniques to take hold.
