Whatever the time, make sure the bees are up and flying. You don't want to start a removal when everybody is home! I prefer to start later in the day. The foragers are gone then...returning bees seem to be so disoriented that they are less of a threat, and if you need to leave them until after dark to remove them you don't have to wait so long. Of course there may be other opinions too!
"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
