How should I control leatherjackets?Updated 8 months ago
To control leatherjackets, you need nematodes, specifically Felti or Carpo, depending on the soil temperature:
- For soil temperatures above 14 degrees, you can use Carpo.
- For soil temperatures below 14 degrees, Felti is most effective.
The first treatment can be done from April through June. To prevent the leatherjackets from returning, a repeat treatment in late August and again in mid-October is recommended.
