Caster bean oil is toxic to moles and grub and the like.

I use it on my lawn to kill the moles and stop there digging up my nice
3 acre lawn.

Works great.

Any idea if it does horrible things to earthworms?

I'm not so sure about being toxic to moles and grubs.
I believe the odor of the castor oil has some ability to drive away
moles when sprayed over a lawn.
I don't believe it harms the grubs that the moles are after.

Castor beans are toxic as discussed in this thread.
Once the oil has been removed, the oil is not toxic.
Moles hunt worms and grubs by sence of smell. Apparently they don't
like the smell of the castor oil!

Peace!
