Precious Pines provide beauty. But they also perform a lot of other duties such as hiding this privy or shading the picnic table.
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.

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.
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:
And can be used on:
Verbenone has been used as part of integrated pest management programs (IPM) for more than a decade. It is A REPELLENT PHEROMONE PRODUCT FOR CONTROL OF THE MOUNTAIN PINE BEETLE. (Dendroctonus Ponderosae), WESTERN PINE BEETLE, (Dendroctonus brevicomus), AND SOUTHERN PINE BEETLE (Dendroctonus frontalis). Many studies show that areas treated with Verbenone, as part of an IPM program, fare significantly better than those that are not. Commercially used by Forest Service, State Agencies, Recreation Areas, Home Owner's Associatons in high value recreational or private land holdings.
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.
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.
For Mountain Pine Beetles, it is our recommendation 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 at a rate of 1 dispenser per tree. In most high elevation and mountain state locations, significant beetle flight begins mid July. Treatment in high elevations should begin during the first week of July. Lower elevations that get hotter sooner, may need to deploy in May and may require a second treatment in July or August. (For lower elevations like the Okanagan Valley, and areas with hotter than average temperatures, sometimes 2 applications are necessary.)
For treatment areas greater than half an acre staple VERBENONE dispensers 6-12 feet above the ground, on the north face of susceptible trees in a grid pattern at a minimum of 20 dispensers/acre. Maximum allowable dose is 60 dispensers/acre/year. For treatment areas between one half and one quarter of an acre, place dispensers at 35 foot intervals around the perimeter and place the remaining dispensers on the north side of the largest diameter trees
Treating larger areas gives a geometrical advantage in so far that beetles repelled from the area try and fly out of the repellent treated area, and the larger the treated area the more beetles are likely to exhaust and die during flight.
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.
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.
BeetleBlock - VERBENONE is intended to be used as part of an integrated pest management system.For best results remove as many beetle infested trees as possible from the site prior to beetle emergence and deploying BeetleBlock - VERBENONE
For treatment areas between one half and one quarter of an acre, place dispensers at 35 foot intervals around the perimeter and place the remaining dispensers on the north side of the largest diameter trees.
For treatment areas greater than half an acre staple BeetleBlock - VERBENONE dispensers 6-12 feet above the ground, on the north face of susceptible trees in a grid pattern at a minimum of 20 dispensers/acre. Maximum allowable dose is 60 dispensers/acre/year.
For protection of individual trees, staple at least 2 dispensers on the north face of the tree (maximum 30 trees/acre) with one dispenser at 6 feet and the other at 12 feet above the ground. For trees larger than 14 inches in diameter (at breast height) use four dispensers stapled to the tree in four cardinal directions (maximum 15 trees/acre). When using four dispensers per tree, alternate the height of adjacent dispensers, two at 6 feet and two at 12 feet above the ground.
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.
