Yellowhead County Now Selling Beetle Block Verbenone

Beetle Block Verbenone is a synthetically produced anti-aggression pheromone that works by repelling newly arriving Mountain Pine Beetles (MPB). Verbenone’s pheromones trick the beetles into believing that nearby trees are full of other MPBs, and they subsequently look to move elsewhere.

Check out our Verbenone FAQ, which includes a proper usage guide, here.

Verbenone may not be an economical solution for those with acres of Pine trees, but may be useful for those with a few coveted trees in their yards. Verbenone has also been proven to work best in areas with low to moderate beetle pressure. High-level areas, such as Robb and Hinton, may not see promising results.

Sales will begin on May 4 and will run all summer or until supplies are gone. The pouches will be sold for $10 a piece ($90 for a 10 pack). Typically, only one pouch is needed for single lone-standing trees. If you have a stand of multiple trees, you can place pouches on any high object (2.5 – 3.5 meters above ground) every 10 to 15 meters throughout the stand of Pine.

Yellowhead County Agricultural Services recommends that those interested in using Verbenone should have their pouches purchased and ready to hang by mid-June. Each Verbenone pouch lasts roughly eight weeks before the pheromone evaporates. The pheromone must be present during the peak flight time of the Mountain Pine Beetle, which usually occurs around mid-July in our region. By hanging the pouch in mid-June you will get about four weeks of protection before peak flight and another four weeks following peak flights.

Verbenone does not protect or remedy trees that have already been affected by MPB and can only protect uninfested trees.

You can purchase Verbenone by appointment only. Simply call in advance and pay for the items over the phone with a credit card. Then choose an office location, date, and time slot for when you can pick up your pouches curbside.

Please call Yellowhead County at 1-800-665-6030 (Edson office) or 1-800-814-3935 (Wildwood office) to place your order or if you have any questions.
