Chris, I think there was a thread on the Knothole, , about this.  Could have been quite a while

I suspect there might be a lot of variability in sensitivity.  Maybe you
screen for non-sensitive crew members.

The only time I experienced it was in a particular tree in September with a
very heavy lace wing fly infestation and I never knew if the problem was the
natural material on the leaves or the clouds of insects every time a branch
was jostled.

Can anyone point me in the direction of some published information on the
on the irritant properties of plane leaves, such as just what causes the
problem, how serious is it, what PPE is appropriate if they have to be
worked on whilst in leaf and if we have to fit our climbers out with
respirators how do we convince the public that the trees pose no danger to
them despite the fact that the climbers look like their kitted up to
survive biological warfare.
