try a few.I was going to try coroplast. Some of them are translucent.
I figure I could paint the outside. I have lots of oops paint.try a few.
I am thinking with no data other than my hunch, it will not work as well.
If the swarms are many you may still do fine.
If you have old comb to melt down,, a coating of the dark beeswax on the interior may do the dual duty of blocking light and offering the scent of a pre used bee hovel.
What about some cheap wall paper, or paste and thick paper, for the inside. However IF the light goes thru there could be heating of the interior so keep that in mind when doing placement. in full sun could heat up inside.
that worksI figure I could paint the outside. I have lots of oops paint.
