What effect does Neem oil have on earthworms?

Asked March 30, 2014, 6:50 PM EDT

In My home garden; I try to stay as Organic as possible.
I was wondering if neem oil would kill beneficial insects such as earthworms?
Or would the worms be fairly safe with Neem as long as not directly sprayed?
As this been studied???
Are earthworms in the insect family???

Earthworms are not insects. They are considered a soft bodied animal. It is my understanding that Neem products are not harmful to beneficials, however, be sure to check any product that it may be mixed with. It is important to remember that insects must eat the treated plant to be killed. Therefore, bees and other pollinators are not likely to be harmed. It can however be toxic to bees if they are directly exposed. Do not treat areas that are actively visited by the bees and other pollinators.Always read the label and follow the instructions. You can find a pdf of the label on the internet by going to: http://www.biconet.com/botanicals/infosheets/70NeemOilLabel.pdf Also check these sites out: http://www.discoverneem.com/neem-earthworms.html http://www.todayshomeowner.com/how-to-use-neem-oil-in-your-garden/ http://npic.orst.edu/ingred/neemoil.html Hope this was helpful.

adding some diluted Horticultural Molasses will also help my beneficials and can't hurt correct?

This is a new one for me. I've not heard of Horticultural Molasses, but from what I've read, I see no conflict. In fact it sounds pretty good!

Thanks I May try molasses in one of my beds

I'd be interested in knowing the results! You can email me at simonru@anr.msu.eduThanks, Ruth
