Thanks MB, I'm a newbeek had a LW hive last yr. iddee explained to me, if caught early enough it can be used to your on personal benefit with only a few hives and worked, we used a innercover with a 6x6 hole stapled screen door wire ( ya can use screen door wire instead of innercover) LW hive over Q rite hive for 7 days ( LW hive with upper entrance) after 7 to 12 days inspect LW hive if they have smelled the strong queen they'll stop laying , and that's what you look for double eggs if you don't have any then remove screen and close off top entrance and combine, check in a week and see if ya need to reduce size of box, drones from LW will be gone .
