Dear Mohammad,

I am not the right address for your question, but I will try what I can and hope Dean will jump in where necessary:

1. surely 'worm' is not equal 'worm', composting worms you find here en.wikipedia.org/wiki/Vermicompost under 'Suitable worm species'.
2. A leech is not a composting worm and looks quite different, please compare pictures for leech under en.wikipedia.org/wiki/Leech with pictures of compost worms referred to in above article.
3. The article which I attached to my earlier posting also talks of heavy metal removal. Please refer to that article and its quoted literature.
4. Interesting observation which adds to the knowledge that vermi-composting is not a single-actor process but that many actors contribute to the aerobic composting process.
5. I am quite sure that there are not special precautions required, probably less than for touching the FS they live in. But Dean will be in a better position to comment. He has had worms as pets for years

Hope that helps, enjoy the forum,
greetings to Iran,
Hajo

Dear Mr.ciao Hajo

Thank you very much for your invaluable information about earthworm, I am very interest about this issue and I have some questions:

1) Is there any difference between wild earthworm which found in garden or commercial worm which may be selected in function ,nutrient requirements and reproduction rate?

2) How could differentiated between earthworms and leech (excuse me if it is fun question) ? because sometimes watch earthworms which they have suction organ in their body .

3) About heavy metal removing by earthworm could you please provide me with any reference?
4) In my experiences I believe they also use of fly and mosquito larvae because I put fruit waste in soil and let fly and mosquito settle on this waste after about one week I add couple earth worm to this controlled waste after 48 hour high dense fly and mosquito population were disappeared .
5) what safety and protection must be considered when working on earthworm , any diseses or alergy may be arise fron eartworm or thier byproducts?

Thank you so much

Mohammad
