Default what to do about mites in a home environment?

Thanks, Pat, Danny, Kenni, and Joe T!

Based on what you all said, I suspect that I don't have mites after all
(hopefully). I just looked carefully under all the leaves of this Phal
without a magnifying glass, and I do not see neither any mites nor any
damage. I may still get a magnifying glass this weekend and look once more
to be on the safe side, but so far at least the Phal in question looks very
healthy. I also tried the paper and circled dot method, and when I checked
again, all dots remained in their circles. And I know that we do have real
spiders in the house, so the web probably was from one of those, as Danny
suggested.

One idea that occurred to me today -- I was reminded of this by the ladybug
that I found the other day:

if I did have spider mites in the orchids after all, could I buy ladybugs
and let them roam our condo, or is that a really bad idea? I know that one
can buy ladybugs for this purpose for greenhouse use, but why not for in the
home?

Aside from having ladybugs flying around, occasional ladybug carcasses on
carpet or elsewhere, the fact that the ladybugs would eventually either
escape through cracks in windows or die, what other problems would there be
with using this solution inside one's home? Is the issue that this would not
be an effective method? I was thinking that this could be a fairly low
maintenance approach to orchid pests, since I would think that it would be
easier and take less time than taking each orchid and spraying it thoroughly
outdoors, or the homeremedies which one would have to find time to apply
several times. I was assuming that if I found mites on this one plant, I
would have to treat them all to be on the safe side, and treating 51 orchids
and 1 bay leaf plant would take more time than I have got on an average
weekend. Time is one of my lowest commodities nowadays and so if/when I do
have any pests in the orchids I would want to use a method of fighting the
pests that would take the least time, and was safe for the baby and us of
course.

Thanks for your insights!

Joanna -- I am not one of the fortunate ones who can see mites with a
magnifier, but the damage is easily visible, even to me. If you have
them, and don't want to take them outside for a real spray, as Pat
suggested, then you are going to have to treat more than once (I generally
figure at least 3x). The oil sprays are pretty effective, with a little
soap added, as long as you get good thorough coverage. Alcohol also
works, and may be easier to spray into all the little nooks and crannies.
The thing with all of these home remedies, however, is that they only kill
the mites they touch. Miss one pregnant female, or a breeding pair, and
they're back off to the races in no time. Kenni

Ok, unfortunately I am beginning to suspect that my orchids do have
mites! :-(

1) the honeydew -- I have seen some on the corners of the leaves of the
one that has had lots of honeydew in general
2) there was a spider web on this orchid as well

What do I do now? Please remember that I live in a condo, so spraying
with pesticides is not an option. Also how quickly do I have to act? I do
not know whether I will have time to treat all 51 orchids + the bay leaf
tree in our condo this upcoming weekend (not sure whether I ever will
have the time to do it come to think of it, given my 5 months old). The
orchids generally appear healthy for now, but I know that if they indeed
have mites this won't last. Yikes!

Given the two points above, is there any chance that it's not mites after
all? Even a remote one? How do I tell for sure? I would so like to avoid
having to treat my entire collection, but I don't want to loose it
either.
