| last year our tomatoes were decimated from tomato horn worms..how can we prevent them from invading practically overnight. Is there something we can use to prevent them again this year. I had heard that you should til your soil in the fall to kill the egss that live in the soil. I refuse to touch them, so picking them off is not an option! |
| Look under leaves and all around the plant. You can often spot their dark, pellet-shaped droppings which can help you locate them. If they are out of control, you can use Bacillus thurengiensis or Bt. It is a biological control--a bacteria that kills only caterpillars and is safe to other insects, humans and animals. However, it will kill all caterpillars, including butterfly larvae. Follow package instructions for application. |
