Default Mealy Bug Treatment Question?

Orthene usually works for mealies, but these days you must read the labels.
The active ingredient is acephate [also sold as Isotox and under other brand
names]. You need one that lists acephate as 75% in strength [in the
concentrate]. It has been coming out in more dilute concentrations, lately,
and these are not only ineffective, they are likely to create resistant
strains. Good growing,

Hello, I've recently noticed that after I water a few mealy bugs come
to the surface of my orchids...
What should I do to get rid of them.
I've heard of X-clude and Orthene, but I would really appreciate some
personal input
Thanks, Sandra

I, too, wondered if it might be what we call "fungus gnats," or even one of
the odd-looking ants, but either way the Orthene should work. If they are
seriously nested in the medium, it would be a good idea to soak them in a
dishpan of water [water level slightly higher than the pots] before
spraying. Kenni

Wait a minute Kenni. Your advice is good if Sandra has mealies but I
question if she really does.
If Sandra only sees mealies when they come to the surface after

watering,
what do you think?
Sandra, do you have mealy bugs on the leaves of your plants too? If not,
are you really sure of what they are?

Ewww, fungust gnats.....
What causes them, what should I do water less?
The potting medium doesn't look broken down, and a lot of my phals are
spiking should I repot?
These little animals are sort of tiny, my sister showed me a photo of
some mealy bugs yesterday, so they can't be it, and none of them are on
the leaves either.
As I said, there's just a few in the potting medium, and they come
above and rest on the aerial roots each time I water & feed.
I was wondering as well, I have a phal bellina, a few days ago I was
looking at the roots and a few of them appear to be turning a brownish
color.
It can't be the potting medium because I took the plant out and checked
it, there's nothing breaking down.
Is it okay if I water with dilluted physan 20 once a month to sort of
ward off any potential for rot in the medium of my phal bellina, I read
somewhere that phal.bellina is a lot more susceptible to root rot....so
should this help a little...

Momma fungus gnats... *grin* Fungus gnats are reasonably harmless,
but are a sign of decomposition in your potting mix. A little
decomposition is probably a good thing (a lot is obviously not). Fungus
gnats look a lot like fruit flies. I have a fungus gnat flying around
my office right now. Driving me nuts...

If you want something harmless, get some Gnatrol, which is a variety of
Bacillus israeliensis (I think). They give the little gnat larvae
serious tummy aches. They used to make a reasonable hobby size of that,
now you might have to buy a gallon.

Failing finding a suitable supply of gnatrol, you could just use sticky
traps. A yellow piece of cardstock covered with some rubber cement
works, or you can buy traps already pre-stickied. I see them at the
hydroponics store. The gnats like bright colors, and get stuck.
Doesn't get them all, but keeps them down to a minimum. You can get
yellow traps or blue traps. I think they are supposed to attract
different bugs. Not a bad idea to have some around to monitor pest
populations.

The potting medium doesn't look broken down, and a lot of my phals are
spiking should I repot?
These little animals are sort of tiny, my sister showed me a photo of

See if you can find a picture of springtails on the internet. That
is my guess. They are effectively harmless, but kind of gross. Like
fungus gnats, they also thrive in decomposing potting mix.

The knats are harmless just irritating!About the phal bellina I have found
this to be a tricky phal to get growing well,even to get growing at all!Give
it warmth & humidity if this fails ditch it and don't by that type again.

As I think you've seen by the variety of responses so far, we can't tell
exactly what you have, but all the likely suspects tend to like decomposing
potting mix. So even if it doesn't look broken down to you, something may
well be going on. Have you tried the "sniff test"? Decomposing media has a
distinct "musty" smell compared to nice fresh stuff.

There are lots of different approaches, as you've probably also seen. If
the plants were mine:

1. If the phals are in short spike, not yet showing much in the way of buds
and certainly not color, I would go ahead and repot -- discarding all old
pots and mix.

2. If the buds are fat, I'd spray for the bugs and then enjoy the flowers,
repotting after they finish blooming.

I do not generally recommend preventive spraying of either fungicide or
pesticide. If you do decide to use the Physan, please use at label
strength -- using it too dilute can create resistant fungi just as spraying
the watered-down acephate products creates resistant insects. Kenni
