Overview
Boxwood leafminer is one of the most common pests of boxwood shrubs. The larvae are the immature stage of a small fly. They spend most of their life between the upper and lower surfaces of boxwood leaves, feeding on leaf tissue. This feeding causes characteristic blistering and discoloration that becomes more noticeable as the season progresses.
Signs of Infestation
- Blistered, puffy leaves
- Yellowing or browning foliage
- Premature leaf drop
- Tiny orange larvae visible inside leaves
- Reduced plant vigor and aesthetic quality
Treatment & Management
Systemic insecticides applied in spring can control leafminer larvae. Contact insecticides timed for adult fly emergence are also effective. Proper plant care and sanitation help reduce damage.
