I personally don't have any right now and hope I don't get it again
But a lot of people have it and really want it gone
I have found several methods to be successful in it eradication
First off my favorite and most successful way is to fill a coffee cup or small heat safe bottle with boiling or near boiling water then take a small medicine syringe the type used to give a child a dose of meds and just squirt it and scald it till it melts away to nuthing
another popular method is warm kalk paste/water actualy injected into the nem
both of these methods can take hours if not days of tedious work to get them all and can involve extensive remodeling of rock work to ensure all are gone
another popular method of getting rid of them is the use of peppermint shrimp as some are said to eat the nuisance nems I personally never had luck with this method
and last but definitely not least is the use of fish like the scat copper banded butterfly or other butterflys I have had hit and miss success with this as the fish tend to eat the ones that are easy to get to but usually miss the smaller ones that are hiding in the cracks of the rocks
