Quick Fixes
Step 1
Remove and dispose of heavily damaged leaves immediately

Spray all plant surfaces with ready-to-use pyrethrin or permethrin insecticide
Step 3
Install yellow sticky traps to capture adult leafminers
Step 4
Repeat application every 5-7 days for 2-3 weeks
Step 5
Monitor daily for new serpentine trails
Step 6
Apply systemic insecticide for faster knockdown if needed

Step 4
Install blue sticky traps around plants to catch adult flies before they reproduce
Step 5
Apply spinosad spray every 7-10 days for 3 weeks to kill emerging larvae
