If you can use a pipette to squirt lemon juice on them, try that and then it's recommended to cover them after with some reef epoxy.
There are youtube vids if you wanna try it.
I did it over a month ago on one and got lucky. It didn't spawn and I never covered it up 'cause it was buried in a hole.
Actually, it was Feb 10th, so I know it worked as there aren't any new ones to see.
