🐝 Sustainable, Organic and Natural Beekeeping Explained

About this simulation

Every low-intervention beekeeping approach — treatment-free, organic-acid, biodynamic or natural/essential-oil — has to answer the same question: how do you keep the varroa mite population below the point where it collapses the colony, without relying on synthetic miticides? This model runs a simplified season for a single hive, growing the mite population week by week and applying whatever knock-down each chosen method allows, so you can see the tradeoffs play out in the 3D hive itself.

How it works

• Mite growth — without any intervention, varroa populations roughly double every few weeks during the brood season; this is modelled as steady weekly compounding.
• Treatment-free — no chemical knock-down at all; the colony instead very slowly builds tolerance (hygienic behaviour) as weeks pass, but a hive can collapse if mites overrun it before that helps.
• Organic acids — oxalic and formic acid are permitted under organic certification and give a strong periodic knock-down, but must be timed carefully to avoid harming brood or the beekeeper.
• Biodynamic — treatment is timed to lunar and brood-cycle rhythms rather than a fixed calendar, giving a moderate but more consistent knock-down.
• Natural / thymol — plant-oil treatments (like thymol) are gentler and need more frequent, smaller applications.
• Bees flying around the comb turn redder as the mite load on them rises; the colony health bar reflects how far mite load sits above the ~3% economic-threshold guideline.

Controls

• Method — choose the beekeeping philosophy driving the treatment schedule.
• Hive type — switch between a stacked Langstroth hive and a single-trough top bar hive.
• Starting mite load — the mite infestation percentage at week 0.
• Simulation speed — how many simulated weeks pass per real second.
• ↺ Restart season — resets week count, mite load and colony health. Drag to rotate, scroll to zoom.

Did you know?

A 3% mite infestation rate (roughly 3 mites per 100 adult bees) is a commonly cited treatment threshold — above it, colony losses climb sharply if nothing is done, which is exactly why timing and consistency matter so much in treatment-free and organic approaches.
