Question
one of my orchids is oozing out a sticky substance from the
stems, so much so that the area around the pot is covered by
it, I have tried washing it off, but I notice it has started
to reappear, when I first noticed it it seemed to be a dark
brown substance, but now it is clear. Also I noticed some on
the pot next to it, could it be just general spread like
around the pot, or is it like a bug that has moved on to the
next plant.

Answer
Aspet, while it is not unusual for orchid plants to "leak" plant sap (which is sticky due to its sugar content), it can also occur in the presence of either mealy or scale insects.  Since the mealy bug is usually white and cottony in appearance, it is more easily spotted than the crawler stage of the scale insect.  The latter is the same color as the plant tissue and is less easily discerned.  Where there are scale insects in the crawler stage, there are also likely to be adults which look like scales.  These do not move, and are darker in color.

As a starting point I recommend that you thoroughly examine the plants for either of these pests.  If you do not see them, soak a cotton ball in rubbing (70% isopropyl) alcohol) and rub down all plant tissues with this.  Any insects will appear on the cotton.  The alcohol will dehydrate and kill the insects it touches and should also remove any excess plant sap oozing from the plant tissues.

If insects show up as a result of these procedures, you will need to take further steps as there may be eggs to hatch in the future. If no insect pests show up then you have plants that, for genetic or other reasons, have an unusually high fluid pressure in their conductive vessels, forcing sap through pores in the tissues.
