˜ Piñon beetle larvae may be present under the bark of dead trees, leaving visible red/yellow dust.

˜ Cut infected trees and transport to a clear, safe area. Burn safely. Infected trees may also be chipped when possible.

˜ Dead trees create situations where fires spread extremely fast.

Spraying a chemical insecticide will create a barrier against beetle infestation. Spraying should take place in early April, with subsequent applications in early July and early September; plan on 3 applications (see below).

˜ Thin living trees giving each tree a minimum of 12' between crowns.

˜ Water the tree roots to an area double the height of the tree, but avoid over-watering.

˜ EPA Hazardous waste regulations require storage Minimum 27EF / Maximum storage 100EF.
