Fungus gnats and control

I am surprised in this tread that insectivorous plants have not been
mentioned earlier. A local small specialist nursery close to my home
that uses bark based compost for permanent pot grown stock, but peat
based for other spring propagation plants relies almost solely on
pinguicula plants placed every yard or two throughout the greenhouse,
and has done so for many years. The larger fleshy leaved P. caudata
types work best but other species are also used, and give a change of
flower colours. I would have thought that the sticky plastic traps
similarly placed would be as effective, but not so appealing.
Peat is only a minor part of my growing composts, as I use various mixes
of soil, commercial soil based compost, grit and composted bark as the
major growing medium, so only odd plants suffer from gnats, and sticky
traps seem to mop up them.
