I'm also in FL. We have 2 types of hives here; Type 1, the beetles invade the first day; Type 2, the beetles invade the first night. We don't put out hives unprotected. Doesn't make a whit of difference if they come with nucs, packages, or swarms, or fly in on their own. They will cause a hive to abscond in a short time, like 2 weeks if not controlled. Thumbs don't work here!
