At its core, the Varroa EasyCheck determines mite counts by using an alcohol wash to physically separate Varroa mites from a sample of bees. Beekeepers collect a set number of bees, place them in the device with alcohol or a similar solution, and shake it vigorously for 60 seconds. This action dislodges the mites, which then fall through a filter basket to the bottom of the transparent container where they can be easily counted.
The alcohol wash method is considered the most accurate and reliable field test for Varroa mite levels. While it requires sacrificing a small sample of bees, it provides the definitive data needed for beekeepers to make critical, timely decisions about the health of the entire colony.
The Mechanics of an Accurate Mite Count
The Varroa EasyCheck standardizes the alcohol wash process, which is widely trusted by scientists and professional apiary inspectors. The procedure is straightforward and designed for repeatable results.
Step 1: Collecting the Bee Sample
Before doing anything else, you must locate and isolate the queen to ensure she is not accidentally included in the sample.
Once the queen is safe, collect a sample of approximately 200 or 300 bees, typically from a frame containing brood. The EasyCheck has clear markings to help you estimate the correct volume of bees.
Step 2: Performing the Wash
Pour a small amount of an alcohol-based solution, such as rubbing alcohol or winter-grade windscreen washer fluid, into the device's clear bowl.
After placing the bees in the inner basket and sealing the lid, shake the device vertically and with force for exactly 60 seconds. The alcohol and the agitation work together to break the mites' grip on the bees' bodies.
Step 3: Counting and Calculating Infestation
The dislodged mites fall through the perforations in the basket and collect in the alcohol at the bottom. After shaking, you can remove the basket of bees and count the mites in the clear bowl.
To determine the infestation level, you calculate a percentage. For example, if you find 6 mites in a 300-bee sample, your calculation is (6 mites / 300 bees), which equals a 2% infestation rate, or 2 mites per 100 bees.
Why the Alcohol Wash is the Gold Standard
While other methods exist, the alcohol wash is the preferred method for professionals who require the most dependable data to manage hive health effectively.
Unmatched Accuracy and Reliability
The alcohol wash provides the most accurate assessment of a colony's mite load. It consistently dislodges over 90% of the mites present on the sampled bees, leaving very little room for error.
Data for Confident Decisions
Because the results are so reliable, beekeepers can confidently track mite populations over time. This allows you to know precisely when an infestation has crossed a treatment threshold, eliminating guesswork.
Simple and Economical
Despite its high accuracy, the process is simple to perform and uses inexpensive, readily available materials. This makes it an accessible diagnostic tool for beekeepers at any scale.
Understanding the Trade-offs
No diagnostic method is without its compromises. Understanding the primary trade-off of the alcohol wash is key to using it effectively.
The Necessary Sacrifice
The main drawback of this method is that it kills the bees in the sample. While unfortunate, sacrificing 200-300 bees to gain a precise understanding of a threat is a small price to pay to protect the health and survival of the entire colony, which may contain 50,000 or more bees.
Comparison to Non-Lethal Methods
Other methods like the "sugar roll" use powdered sugar to dislodge mites without killing the bees. However, these methods are widely considered less accurate and more prone to user error. A falsely low reading from a sugar roll can give a beekeeper a dangerous sense of security while mite populations grow unchecked.
Making the Right Choice for Your Goal
Your approach to mite testing should align with your management philosophy and tolerance for risk.
- If your primary focus is maximum accuracy for treatment decisions: The alcohol wash is the definitive choice for generating reliable data to protect your hives.
- If your primary focus is avoiding any harm to bees: A sugar roll is an alternative, but you must acknowledge its lower accuracy and the risk of underestimating the true mite load.
Ultimately, accurate monitoring is the foundation of proactive and successful hive management.
Summary Table:
| Step | Key Action | Purpose |
|---|---|---|
| 1 | Collect 200-300 bees (ensure queen is safe) | Obtain a representative sample for accurate testing. |
| 2 | Shake with alcohol solution for 60 seconds | Dislodge mites from bees through agitation. |
| 3 | Count mites in the clear bowl | Calculate infestation rate (e.g., mites per 100 bees). |
