The choice between mite monitoring methods is a calculation of accuracy versus hive preservation. To select the right tool, you must weigh your need for precise infestation data against your willingness to disturb the colony or sacrifice a small number of bees.
Core Takeaway While sticky boards provide a passive look at mite trends over time, active sampling is required for immediate treatment decisions. The alcohol wash is the industry standard for accuracy but is lethal to the sample, whereas the sugar roll offers a non-lethal alternative at the cost of slight precision.
The Gold Standard: Alcohol Wash
When Accuracy is Paramount
If your primary goal is to determine the precise infestation rate of a colony, the alcohol wash is the superior choice.
This method involves vigorous separation of mites from bees using alcohol or low-suds windshield wiper fluid.
Because the liquid kills the mites and detaches them completely, it leaves little room for error in the count.
The Sample Cost
The trade-off for this high accuracy is the lethality to the sampled bees.
Typically, this requires a 1/2 cup sample (approximately 300 bees).
While this results in the loss of the sample, this number represents a very small percentage of a healthy colony and is generally considered a worthy sacrifice for reliable data.
Critical Safety Step
Before performing an alcohol wash, you must locate and isolate the queen.
Ensuring she is not included in the sample is the single most important safety precaution of this method.
The Preservation Approach: Sugar Roll
Non-Lethal Estimation
The sugar roll is the preferred active method for beekeepers who prioritize preserving every bee in the sample.
Like the alcohol wash, it uses a sample size of approximately 300 bees.
Instead of a liquid solution, powdered sugar is used to dislodge the mites, allowing the bees to be returned to the hive alive after monitoring.
Acceptance of Variance
Beekeepers choosing this method accept that the count is an estimate, not an absolute.
Because the bees remain alive and the separation is less aggressive than a liquid wash, some mites may remain attached to the bees, potentially yielding a slightly lower count than the actual infestation level.
Passive Monitoring: Sticky Boards
Minimal Disturbance
Sticky boards are the best choice for longitudinal monitoring without opening the hive.
These adhesive sheets are placed on the bottom board to capture mites that fall naturally or due to grooming behavior.
This method is entirely non-invasive and allows for continuous data collection over a 24 to 72-hour period.
Trend Analysis Over Time
This tool is less about determining immediate infestation percentages and more about observing population dynamics.
By calculating the average daily mite drop, you can track the effectiveness of treatments or the growth of the mite population over the season.
The adhesive layer ensures that fallen mites cannot re-parasitize the bees or be removed by colony cleaning behavior, providing a reliable record of mortality.
Understanding the Trade-offs
Precision vs. Preservation
The fundamental trade-off is that accuracy usually requires sacrifice.
The alcohol wash offers the highest accuracy because the vigorous washing ensures almost 100% of mites are detached, but the bees do not survive.
The sugar roll saves the bees, but the gentle nature of the process may result in undercounting mites, potentially masking a threshold that requires treatment.
Snapshot vs. Movie
Active methods (washes and rolls) provide a "snapshot" of the infestation level at that exact moment.
Sticky boards provide a "movie" of mite activity over several days.
However, sticky boards can be labor-intensive to count and do not translate directly to a "mites per 100 bees" threshold as easily as active sampling methods do.
Making the Right Choice for Your Goal
- If your primary focus is treatment decisions: Use the Alcohol Wash to get the most accurate infestation percentage to compare against treatment thresholds.
- If your primary focus is preserving livestock: Use the Sugar Roll to get a workable estimate without killing the sample bees.
- If your primary focus is long-term trends: Use Sticky Boards to track natural mite drop and treatment efficacy over time without disturbing the colony.
Select the method that aligns with your current need for data precision versus your tolerance for hive intervention.
Summary Table:
| Method | Type | Accuracy | Colony Impact | Best Use Case |
|---|---|---|---|---|
| Alcohol Wash | Active | Highest | High (Lethal to sample) | Immediate treatment decisions |
| Sugar Roll | Active | Moderate | Low (Non-lethal) | Precise estimation while preserving bees |
| Sticky Board | Passive | Trend-based | None | Long-term population tracking & treatment efficacy |
