RE: White worm culture
Barry,
I have also tried mothballs. Several in a sweater box sized container of
white worms. No impact at all on the mites. I wasn't bothered by any flies
at the time so I can't say if they are effective against them.
Wait a minute here! Let's see, I didn't have flies. I used mothballs. No
flies ever invaded the culture. Therefore, the mothballs must have been the
only thing effective against the flies! Makes sense to me.
Thanks,
mike

You may want to try placing a mothball in the culture. Just stick in one
corner of the container. I have friends in the UK who swear that this will
control mites. I can tell you that I have used mothballs to try to control
little flies that get in my grindal worm cultures. The mothballs do not
harm the grindal worms, so I doubt that they would harm the white worms.
I have seen some comments about white worms doing well at high
temperatures, like in the 70s and 80s. To my knowledge that goes against
all conventional wisdom. White worms do best in the mid-50s to low 60s, and
cultures will at best hang on in the 70s. That has been consistent with my
experience.
Grindal worms, in contrast, do well in the mid- to high 70s. I wonder if
there has been some confusion in the identity of the worms being discussed.
White worms are considerably bigger than grindal worms. On the other hand,
I find grindal worms easier to culture under my conditions and I can
produce enough to feed my whole fishroom regularly. They are also a great
size for fish larger than about 15 mm, and they're useful for even full
grown nothos.
I don't do white worms any more as I have ready access to black worms.
