I haven't worked with nematodes myself but I have given a few talks on
biocontrol and might be able to partially answer part of your questions
Apparently they have shown promise, particularly in small well-defined
habitats like woodland pools etc. but are sensitive to water quality and often
do not acheive high enough control rates in the field.

The problem is apparently that they are very difficult/expensive/tricky to
mass produce and the commercial outfits have basically given up.

Natural parasitism of some snow pool Aedes species by mermithids is incredibly

See the article "The future of microbial insecticides as vector control
agents" (B.A. Federici 1995; J. Amer. mosq. contr. Assoc 11:260-268) for an
overview of the current status of various biocontrol agents including
