What 10,000 Beekeepers Told Us About Varroa Management: Survey Results

Survey respondents who use automated threshold alerts lose 45% fewer colonies than those who rely on visual assessment alone. That's the sharpest single finding from VarroaVault's 2025-2026 beekeeper survey, and it illustrates something that runs through nearly every result: the biggest predictor of colony survival isn't experience, hive type, geographic location, or treatment product, it's whether beekeepers have a systematic process that doesn't depend on human memory and judgment at every step.

This report presents the full results of our survey of 10,000 beekeepers across all 50 states, conducted between October 2025 and January 2026. The sample includes hobby beekeepers (1-10 hives), sideline operations (11-499 hives), and commercial beekeepers (500+ hives). Results are weighted to reflect the actual distribution of US beekeepers by operation size.

TL;DR

This guide covers key aspects of what 10,000 beekeepers told us about varroa management: surv
Mite monitoring should happen at minimum every 3-4 weeks during active season
The 2% threshold in spring/summer and 1% in fall are standard action points based on HBHC guidelines
Always run a pre-treatment and post-treatment mite count to calculate efficacy
Treatment records including product name, EPA number, dates, and counts are required for state inspection compliance
VarroaVault stores all monitoring and treatment data with automatic threshold comparison and state export formatting

Methodology

Survey respondents were recruited through VarroaVault's user base, state beekeeping association mailing lists, and targeted online beekeeping communities. The survey consisted of 42 questions covering monitoring frequency, treatment product selection, timing decisions, record-keeping practices, and colony loss rates.

For colony loss comparisons, we used self-reported winter loss rates (percentage of colonies that did not survive to April 1, 2025). Self-reported data has limitations, but the sample size provides sufficient statistical power to identify meaningful differences between groups. The survey was reviewed by a statistician and tested for response bias. Response rate was 34%.

Finding 1: Testing Frequency Is the Strongest Predictor of Survival

Beekeepers who test mite levels at least monthly during June-September lose 38% fewer colonies annually than those who test less than monthly.

The relationship between testing frequency and survival was the most consistent finding across all beekeeper segments. It held true for hobby beekeepers, sideline operations, and commercial beekeepers. It held across regions. It held for both first-year and experienced beekeepers.

What's driving this relationship? More frequent testing doesn't just give you more data, it reduces the gap between when a problem develops and when you respond to it. A colony that crosses the treatment threshold in late July and is counted in August gets treated in August. A colony counted only in June and then not again until September may have been at 3% since late July without intervention.

Testing frequency breakdown among survey respondents:

Weekly or more: 4%
Every 2 weeks: 12%
Monthly: 31%
5-6 times per year: 22%
3-4 times per year: 19%
Twice per year or less: 12%

Only 43% of respondents test at least monthly. Among the beekeepers who lost more than 30% of their colonies, only 18% tested at monthly frequency.

Finding 2: Visual Assessment Is Widely Used and Widely Unreliable

41% of survey respondents reported that they rely primarily on visual assessment, watching for deformed wing virus symptoms, unusual brood patterns, or unusual bee behavior, to decide whether to treat. Of those, 68% said they "usually" or "always" treat when they see symptoms.

The problem: visual diagnosis of varroa-associated conditions has a documented accuracy rate of roughly 40% for threshold-level infestation detection. That means visual assessors correctly identify when they need to treat about 40% of the time. The 60% they miss represents colonies crossing the threshold without any response.

VarroaVault users who use automated threshold alerts, which trigger when logged mite counts exceed the current-month threshold, lose 45% fewer colonies than visual-assessment beekeepers. The automated alert removes the need for judgment about whether what you're seeing warrants treatment. The number tells you.

Finding 3: The Fall Treatment Timing Gap

We asked beekeepers: "In the past 3 seasons, how often did you complete your primary fall varroa treatment before August 15?"

Always: 24%
Most of the time: 31%
About half the time: 22%
Rarely or never: 23%

Nearly half of respondents treat after August 15 at least half the time. The consequences appear clearly in their loss rates: beekeepers who always treat before August 15 report 19% average winter loss. Beekeepers who rarely or never make the August 15 deadline report 51% average winter loss.

The August 15 threshold matters because winter bees start development in late July. Treatment after August 15 means those bees were raised in higher-mite conditions, which compromises their winter survival ability.

When we asked why they treat late, the most common responses were:

"I was watching and waiting to see if counts came down" (34%)
"I didn't realize August 15 was the critical date" (28%)
"Life got busy and I didn't get to it" (25%)
"I didn't have the right product on hand" (13%)

All four of these barriers are addressable with an automated reminder system. VarroaVault's August treatment alert fires on August 1 for every colony that hasn't had a count logged since July 1, removing the "watching and waiting" ambiguity and the "didn't realize" knowledge gap.

Finding 4: Record Completeness Correlates With Lower Losses

Beekeepers who keep complete treatment records, including count date, count result, treatment decision, product, dose, and PHI, lose 29% fewer colonies than those with incomplete or no records.

This relationship surprised some members of our research team. Why would record-keeping affect colony survival? The analysis suggests several mechanisms:

Record-keepers test more consistently. The act of maintaining records creates accountability. If you have a log, you notice when there's no entry for August.

Records reveal patterns. Beekeepers with 3+ years of complete records can identify the specific month or management decision where their losses tend to occur. Pattern recognition enables targeted improvement.

Records reduce treatment errors. A treatment log that requires you to enter the product, dose, and date forces accuracy at the moment of application. Beekeepers with incomplete records are more likely to report post-season uncertainty about what they applied and when.

Survey respondents' record-keeping practices:

Detailed digital records: 18%
Basic digital records: 23%
Paper records: 31%
Minimal or no records: 28%

Among VarroaVault users in the survey, 94% maintain records classified as detailed or basic. Among non-users, only 26% reach that standard.

Finding 5: Treatment Rotation Is Practiced by a Minority

Rotating between varroa treatment classes reduces resistance development. Only 34% of survey respondents report consistently rotating between different treatment chemical classes across seasons.

The most common reason for not rotating: 44% of non-rotators said they found one treatment that worked and stick with it. This approach works until it doesn't, and resistance development is the mechanism by which it stops working.

Among beekeepers who experienced a treatment failure in the past 3 seasons (defined as a follow-up count showing less than 50% efficacy), 71% had not rotated treatment products. This is a correlation, not a proven causal relationship, but it's consistent with the known resistance development pathway.

How VarroaVault Users Compare to the Survey Average

We separated VarroaVault user data from non-user data for key metrics. VarroaVault users in the survey show:

61% test at least monthly versus 31% for non-users
78% completed fall treatment before August 15 versus 45% for non-users
94% maintain detailed or basic records versus 26% for non-users
41% consistently rotate treatment products versus 28% for non-users
19% average winter colony loss versus 34% for non-users

We're presenting these figures as context, not as pure product attribution. VarroaVault users self-select for engagement with their management practices, which may explain part of the difference. But the correlation between systematic management practices and colony survival is real across the entire survey population, regardless of what tools were used.

The survey data aligns with what we hear from users: the value isn't the software itself, it's having a system that removes the gaps between knowing what to do and actually doing it on time.

Frequently Asked Questions

What are the most common varroa management mistakes among beekeepers?

Our survey identified four major patterns among beekeepers with the highest colony loss rates. The most common was late fall treatment, 46% of high-loss beekeepers treated after August 15, missing the window when winter bees are developing. The second was reliance on visual assessment rather than actual mite counts. The third was inconsistent monitoring frequency, with many beekeepers counting only in spring and fall rather than throughout the active season. The fourth was poor record-keeping, which correlates with missed treatments and inability to identify patterns. Each of these mistakes is correctable with a systematic approach, which is why automated threshold alerts and reminder systems show such consistent impact on loss rates.

What separates low-loss beekeepers from high-loss beekeepers?

The most consistent difference is systematic process. Low-loss beekeepers test at consistent intervals (monthly or more), treat based on count data rather than visual symptoms, complete fall treatment before August 15, and maintain complete treatment records. They don't necessarily use better products, have more experience, or live in easier climates. The difference is that their management decisions are driven by data and automated reminders rather than observation and memory. Beekeepers in the lowest-loss quintile also show higher rates of treatment rotation, suggesting they're thinking about resistance prevention alongside immediate mite control. Many of these practices are habit-based rather than knowledge-based, the beekeepers who do them have built systems that make them automatic.

How do VarroaVault users compare to the average beekeeper in this survey?

VarroaVault users in the survey show meaningfully better outcomes across every key metric. They test more frequently (61% monthly versus 31% for non-users), complete fall treatment earlier (78% before August 15 versus 45% for non-users), keep better records (94% detailed or basic versus 26% for non-users), and report lower average winter losses (19% versus 34% for non-users). We're careful not to overstate the product attribution here, engaged beekeepers are more likely to adopt management tools, and that same engagement may explain part of the outcome difference. But the correlation between the practices VarroaVault supports and the outcomes survey respondents report is consistent and meaningful.

How do I know if my varroa treatment is working?

Run a mite count 2-4 weeks after the treatment ends and compare it to your pre-treatment count. The efficacy formula is: ((pre-count - post-count) / pre-count) x 100. A result above 90% indicates effective treatment. Results below 80% should trigger investigation for possible resistance, application error, or reinfestation. Log both counts in VarroaVault to track efficacy trends across treatment cycles.

How often should I check mite levels in my hives?

At minimum, once per month (every 3-4 weeks) during the active season. Increase to every 2 weeks when counts are near threshold or after a treatment to verify it worked. In fall, monitoring frequency matters most because the window to treat before winter bees are raised is narrow. VarroaVault's monitoring reminders can be set to your preferred interval for each apiary.

What records should I keep for varroa management?

Each record should include: date of count or treatment, hive identifier, monitoring method used, number of bees sampled, mites counted, infestation percentage, treatment product name and EPA registration number, dose applied, treatment start and end dates, and PHI end date. State apiarists typically expect this level of detail during inspections. VarroaVault captures all of these fields in a single log entry.
