This little sack thing was on the tomato plant today. When it was touched, these little worm-looking things popped out, like a spider sack of worms.

  • What are they?
  • Why are they on the plant?
  • Are they harmful to the plant or to us?

Thanks!

Probably white fly larva. Spray the plant down with hydrogen peroxide watered down by about 3:1 at a minimum. Alternatively you can buy some oil based sprays (neem and others, iirc) that protect against mold, fungus, white flies, etc.

Someone told me that Dawn dish soap, watered down, can be sprayed on the plants to keep bugs off. Is this true for food plants?

Will it harm the plants or the ground, do you know? I haven’t done it, because it doesn’t make sense that it’s not harmful. It’s soap. I don’t know.

Also dissolve green soap in water will help with larvae. Just need to spray well, top and bottom of the leafs.

Yeah, a little dawn or similar in a spray bottle works as well. When you start seeing shit like this you need to take care of it asap. They can spread and destroy other plants and even neighbors plants.
