sunkissed said:The danger with the flatworm isn't to plants, but because rats and mice eat them-- then the mice droppings can contaminate the air. A person could develop meningitis, it's called Lung Worm, a parasite in the lungs and has to be treated. The flatworm also feed on good earthworms, slugs, snails, etc...So more like damage to the ecosystem. They favor snails more than anything else.
Also the flatworm vomits a substance that can harm skin, so don't touch them. The way to kill them is to pour boiling water on top of them.
You are to report the worm if you find one, see this article: http://www.slashgear.com/how-t...
Whiteflies are a pain. I don't like hearing about a new rare strain at all. ugh!
