What concentration do you use Trevor?  Inside of supers?

I have also used CN for near 40 years.  Boxes are dipped in a mix of
linseed oil and varsol with 1% CN and maybe some titanium dioxide or
mistint alkyd paint for pigment,  They are air dried for at least a month
before use.

Queens are not marked, and never done any experiment with controls.
But never noticed a problem and boxes last a reasonable length of time and
the yearly tests on my honey have never shown any detectable residue.

Good for rot, but does not deter carpenter ants, so probably doesn't help
with your termites either.
