Let's begin with a single hive setup situated in the United Kingdom, with an initial investment cost of £300 for a complete ThermoMite system. The average value of a colony stands at approximately £440. Based on historical data, varroa mite infestation can result in colony losses ranging from 10% to 50%. For the purpose of this illustration, we will adopt a conservative estimate of 20% loss. This equates to a colony damage cost of £88. Additionally, we can anticipate a loss of at least £64.80 in honey production. Furthermore, introducing new bees to an established colony can lead to a decline in overall honey production by up to 50%, causing further financial loss due to reduced hive effectiveness and efficiency.

By combining the figures for avoided losses and total gains, beekeepers can benefit to the tune of approximately £298.60 per year, resulting in a payback period of around 12 months for the ThermoMite system. Considering its reusability, the long-term advantages offered by this system are truly substantial.

Utilizing a single ThermoMite kit across multiple beehives leads to significantly greater benefits and returns. Assuming an initial investment cost of £300 and an overall colony value of £1320, the potential value of colony losses would amount to £264. This figure alone almost covers the entire cost of the ThermoMite system. However, when factoring in the aforementioned honey value losses, colony efficiency losses, and honey production gains, the total net savings and gains can reach an impressive £895.80. As a result, the payback period becomes less than 4 months.
