Kathleen:

It sounds like you have mealybug. Or mold.

Whatever. This is a pretty good all round bug killer.

Make an infusion of nicotine from 3 - 4 cigarettes (a palmfull of butts) in
one half liter of water. Wait overnight and strain. Add a couple-three
drops of liquid soap, a drop of garlic oil and one half litre of water.
Pour into a spray bottle, shake and mist _heavily_. Repeat every 8 to 10
days for a month. Whitefly, mealybug, spidermite, etc, leave nits. Make it
drippy but just let the mist layer the soil. Flush the soil after every
misting. Make a new brew every two days if using regularly (nicotine
degrades very quickly).

Spray _all_ your plants! Wash your curtains, hands, stands etc, with
bleach. (Diluted, of course)

If you still have things crawling or flying around after that: did you pick
off the fuzzy white things? Dead mealybugs may contain nits. Also if they
are the kind that get in your soil ... change it, of course, and maybe the
best you can hope for is control. The alternative is throwing out the
plant(s). Been there. Prefer it. CPs will tolerate this kind of treatment,
but they do not like it for extended periods. Droseras may react by dying
if one is heavy handed. Remember, most Droseras eat anything on their
leaves. You have to worry about their crowns and roots. Do not use this in
any closed system where there is a chance of buildup. Sorry, you are on
your own with the Utrics.

Lose the veggie oil, that can't be good. Anyone?
