How to: Manage Cabbage Loopers in Your Garden

Cabbage Loopers blog post
The cabbage looper is the caterpillar of a grayish moth with a silver spot in the middle of each wing. You can distinguish them from the cabbage worm by looking for 4 white stripes running down the body. The eggs are dome-shaped, light green, and are laid on the underside of the leaves.
 
Treatment Options:
  • Hand-pick (or pay your kids a quarter each to handpick for you like we do!)
  • Cover the plants with insect netting (floating row covers) from when they are babies. This will help to prevent them from becoming an issue!
  • Use the organic pesticide, BTK (bacillus thuringiensis Kurstaki). BTK is a naturally occuring microorganism that sickens and kills caterpillars without harming butterflies, bees, and other beneficial insects. There are varied opinions regarding the safety of BTK, but it’s classified as an organic treatment and is certainly safer than using a more toxic pesticide.
