It wouldn't be honey or wax, unless they were inside the door itself and it is leaking out. We just had a swarm of bees move ito one of the walls of our house. In 3 days there were several thousand bees (about a 10L bucket full solid) and numerous sheets of beautifully constructed honeycomb in the wall cavity. The wall was hot to touch and buzzing. They do not muck around! We had to get a beekeeper to re-house them in a hive and take them away, after pulling off the wall sheeting.
It sounds like you have something form wasps or sap. Either way, hot soapy water should disolve it.
