Burr Comb and Cross Comb in Langstroth Hives

Understanding Burr Comb and Cross Comb in Langstroth Hives Burr Comb Burr comb refers to small, irregular wax structures built by bees in unintended gaps within the hive, such as between frames, under the lid, or across the inner cover. These structures arise when spacing within the hive exceeds the ideal bee space, which is approximately 6 to 9 millimetres. In these situations, bees instinctively fill the space with wax or propolis (Bradbear, 2009; Seeley, 2010). Langstroth’s original design emphasized this precise spacing, noting that deviations would prompt bees to either block tight gaps with propolis or fill wide spaces with comb (Langstroth, 1853). Cross Comb Cross comb occurs when bees construct comb at angles that do not align with the frames. Instead of building straight within the plane of a frame, the comb stretches across adjacent frames. This results in disorganized construction that complicates inspections and often leads to the destruction of comb during hive man...
