Treatment
Verbenone Buffer
 For Verbenone-Only, start with fresh attacks and continue treating uninfested trees within marked buffer. For Verbenone-Plus-Felling, treat buffer trees only. Continue treating trees until minimum buffer requirements are met. If number of pouches calculated exceeds minimum buffer requirements, continue treating until all pouches are used.
Verbenone-Only
3 trees (Minimum = 40 ft.)
Verbenone-Plus-Felling
2 trees (Minimum = 25 ft.)
