🧼 Apiary Hygiene: Sanitation Habits That Keep Disease Out

About this simulation

A hive tool touches frame after frame, hive after hive, during every inspection round. If it is never cleaned it becomes a shuttle for spores, mites and bacteria — carrying a little of whatever the last hive had straight into the next one. This model follows one hive tool down a row of hives during a routine inspection, tracking how much "spore load" it picks up and hands on depending on whether — and how — it gets sterilised in between.

How it works

• Contact transfer — every time the tool touches a hive, it both deposits some of its own load into that hive and picks up some of that hive's load.
• Tool sterilisation — between hives the tool can pass a hygiene station: a flame scorch burns off almost all residue, an alcohol wipe removes most of it, and no cleaning carries everything forward.
• Unmanaged dead-out — a collapsed colony left uninspected acts as a standing reservoir of contamination; opening it with an unclean tool seeds every hive visited afterwards.
• Hive colour tracks spore load from green (clean) through amber to red (high risk), and a small haze cloud above each hive scales with its load.

Controls

• Tool sterilisation — choose no cleaning, an alcohol wipe, or a flame scorch between hives.
• Hives in the row — how many colonies the inspection round visits.
• Inspection speed — how quickly the tool moves through the round.
• Include an unmanaged dead-out hive — adds a collapsed colony as a contamination source at the start of the row.
• ↺ Reset apiary — clears every hive and the tool back to zero.

Did you know?

Many experienced beekeepers carry two hive tools and a small propane torch or tub of washing soda solution specifically so a tool can be scorched or dunked between colonies — especially after opening a weak, dying or dead-out hive, where American foulbrood spores can otherwise remain viable in wax and wood for decades.
