Honeycomb

Honeycombs are acquired by destroying Bee Hives, unless burned down (which yields Ash).

Honeycombs are mainly used to build Bee Boxes but can also be used in Taffy and Pumpkin Cookie Crock Pot recipes as a substitute for Honey or as a neutral filler in any other recipes. However Honeycomb itself cannot be eaten.

An easy way to get it without losing Health is attacking the Bee Hives at Dusk when all normal bees go to sleep, when the killer bees come out to kill you, proceed to run in big circles to keep them a fair distance away from you, since they are far slower than the player it becomes an easy task even more if there is a Road surrounding the nest, then hit the Hive 3 or 4 times depending on how away they are and repeat process until the Hive is destroyed.

You could also capture all the bees normal and killer, then destroy the nest and create your own. Providing you have a Beekeeper Hat their attacks will be almost worthless. You can also make a trap with the killer bees to deceive Krampus.
