We often get bags of used baling twine from farmers, and the twine is a
pretty good smoker fuel.  It is readily available and easy to get
smouldering, although it doesn't seem to last very long between refills.
(Another drawback is that it tends to produce hot smoke after it's been
smouldering a few minutes.)
 
QUESTION:  Almost all of the twine we get is light green in color,
suggesting that there is some type of preservative on/in it.  Anyone know
what it is, or if products of its combustion might be especially
dangerous/toxic to the bees?
 
Many thanks,
