There are three insecticides for pine beetles that are specifically registered for use in preventing infestations: carbaryl (Sevin SL and XLR, and others), permethrin (Astro, Dragnet and others), and bifenthrin (Onyx). Only the insecticide formulations that are labeled to protect trees from pine beetle attacks should be used, as these formulations include additives that bind the active ingredient to the bark.
TigerTree exclusively uses permethrin as an insecticide for pine beetles for our private customers. We do our best to minimize its adverse effects on the environment and other creatures.
Effects on other organisms: permethrin is extremely toxic to bees and other beneficial insects if present during application, or within 24 hours thereafter.
