SPLAT Verb is an environmentally friendly repellent that provides sustained and controlled release of the verbenone anti-aggregation pheromone. Verbenone is naturally produced by mountain pine beetles and several other species of bark beetles towards the end of a mass attack. The presence of verbenone signals new beetles approaching the infested tree that it is already too overcrowded to serve as a suitable host. By applying SPLAT verbenone to a healthy and uninfested tree, host-seeking mountain pine beetles will identify a tree as an undesirable host and leave it unharmed.
Field studies have shown SPLAT Verb to be highly repellent of mountain pine beetles on both single-tree and small stand levels, and it is an outstanding alternative to standard MPB treatments due to its high-level of control, long field life, and simple application methods.
In a recent study on the efficacy of SPLAT Verb on individual lodgepole pines, there was a 0% mortality rate on trees treated with SPLAT Verb, compared to a 93% mortality rate in untreated trees. In small stands, treatment with SPLAT verbenone proved nearly twice as effective as an alternative verbenone product and reduced tree mortality compared to an uncreated control by a factor of 6.
