Re: Is it too late to do a cutout or trapout?
What have you got to lose? It sounds like the bees are going to get killed, otherwise. Sure, they might not make it after you cut them out. But suppose they do?
The homeowner may find that spraying isn't the wisest thing for him to do. He's going to have to open the wall up and clean it out, anyway, or all that honey is just going to attract pests. Or it's all going to melt and run over time, and cause problems.
I have no experience with cutouts. Just my $0.02.
Don't provoke a hive full of angry bees.
