shb and nematodes

[duck]

so someone suggested the other day that we will find something that preys upon shb.  I was at a feed store in Houston today, and poking around some of their stuff and was told about the nematodes.  I was told you spray them around your hive and they attack the larvae.  How effective might this approach be?  Anyone attempt this yet?

I think (but I might be wrong here) Tillie tried it.   May be on her blog somewhere.   http://beekeeperlinda.blogspot.com/
