You can Telegrab those things, that will work guaranteed.

You've actually stumbled upon a different version of an ectoplasmator. A "ghost ectoplasmator". There's a chance of obtaining it from a ghost monster such as a Banshee or even a revenant, alongside with the normal ectoplasmator.

And yes, telegrabbing it is the only way to retrieve it.
