How to identify
- Pinhead-sized dark beetles that jump when disturbed
- Many small round holes in leaves (shotgun damage)
- Worst on seedlings and first true leaves
Damage: Stunted seedlings; heavy damage can kill young plants.
Control methods
- Floating row cover from day of transplant or sowing.
- Keep beds moist and growing fast — stressed seedlings suffer more.
- Yellow sticky cards for monitoring only.
