If you are talking about the white corplast (corrugated plastic)nucs be aware that there are translucent so the sun shines into them a bit. I use them all the time for making splits but I don't know how good they would be for swarm traps. Another problem is when trying to keep bees in them they tend to over heat in the summer here and need to be kept in the shade.
Bud makes his out of black corplast. I'd imagine that would limit the light from the sun.
"In the first place, we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, or origin. But this is predicated upon the person's becoming in every facet an American, and nothing but an American...There can be no divided allegiance here. Any man who says he is an American, but something else also, isn't an American at all. We have room for but one flag, the American flag...We have room for but one language here, and that is the English language...And we have room for but one sole loyalty and that is a loyalty to the American people."
Theodore Roosevelt 1907
