Apivar offers a proven application process, backed by extensive testing and decades of experience, for effective Varroa control within bee colonies.
What are Apivar Strips?
Apivar Strips are a widely utilized and effective treatment for controlling Varroa destructor mites in honey bee colonies. These strips contain Amitraz as the active ingredient, a synthetic acaricide specifically designed to target and eliminate these harmful parasites. They are available in various package sizes – 4, 12, and 60 strips – allowing beekeepers to treat anywhere from 2 to 30 colonies with a single purchase.
The strips are designed for easy suspension between frames within the brood box, utilizing either a toothpick, match, or the provided triangular tag. Proper application, following the instructions meticulously, is crucial for optimal results. Experienced beekeepers have consistently found that adherence to the recommended guidelines yields superior Varroa population control compared to improvised methods.
Apivar has been a trusted solution for over a decade, though alternative treatments like Oxalic Acid are gaining popularity.
Active Ingredient: Amitraz
Amitraz is the core active ingredient within Apivar Strips, functioning as a potent acaricide specifically targeting Varroa destructor mites. It disrupts the nervous system of the mites, leading to paralysis and ultimately, their elimination. Each Apivar strip contains 500mg of Amitraz, carefully formulated for controlled release within the bee colony.
This synthetic compound has proven highly effective in combating Varroa infestations when used correctly. However, it’s crucial to understand that mites can develop resistance to Amitraz over time, necessitating responsible usage and consideration of alternative treatments like Oxalic Acid.
Amitraz is effective against external parasitic diseases caused by Varroa destructor, sensitive to the compound. Always adhere to the recommended dosage – two strips per brood box – and observe the 14-day withdrawal period before honey supering to ensure honey safety.
Target Pest: Varroa Destructor Mites
Apivar Strips are specifically designed to combat Varroa destructor mites, the most significant threat to honey bee health globally. These external parasites feed on bee hemolymph (blood), weakening bees and transmitting viruses, ultimately leading to colony collapse if left untreated.
Varroa mites reproduce within the capped brood cells, multiplying rapidly and causing substantial damage to developing bees. Effective control is vital for maintaining strong, healthy colonies. Apivar’s Amitraz actively targets these mites, disrupting their lifecycle and reducing their population within the hive.
Monitoring Varroa levels is crucial, as infestations can quickly escalate. Apivar provides a reliable solution when used as part of an integrated pest management strategy, alongside tools like Véto-pharma EasyCheck for accurate assessment and timely intervention.
Understanding Varroa Mites and Varroatosis
Varroa mites cause significant harm to bee colonies, transmitting viruses and weakening bees; monitoring levels is essential for effective treatment and hive health.
The Impact of Varroa Mites on Bee Colonies
Varroa destructor mites represent a severe threat to honey bee colonies worldwide, impacting their health and survival in numerous ways. These external parasites feed on the hemolymph (bee blood) of both adult bees and developing larvae, weakening the bees and reducing their lifespan. This feeding process also transmits debilitating viruses, such as Deformed Wing Virus, Acute Bee Paralysis Virus, and Chronic Bee Paralysis Virus, which further compromise the bees’ immune systems and overall health.
A heavy Varroa infestation can lead to colony collapse, particularly during the winter months when bees are already stressed. Infested colonies exhibit reduced foraging activity, decreased brood production, and an increased susceptibility to other diseases. The mites reproduce within the capped brood cells, exponentially increasing their population within the hive. Untreated infestations can quickly escalate, leading to significant economic losses for beekeepers and posing a threat to pollination services crucial for agriculture.
Effective Varroa management is, therefore, paramount for maintaining healthy and productive bee colonies.
Symptoms of Varroa Infestation
Recognizing the signs of a Varroa mite infestation is crucial for timely intervention and colony health. Visible symptoms often include deformed wings in emerging bees, a clear indication of Deformed Wing Virus transmission. These bees struggle to fly and have a significantly shortened lifespan. You may also observe bees with bloated abdomens, crawling on the hive entrance, or displaying general weakness and trembling.
Brood patterns can become spotty or irregular, with patches of uncapped or dying larvae. An increased number of pupae failing to develop properly is another telltale sign. A visual inspection of adult bees may reveal mites clinging to their bodies, particularly on the abdomen, although detecting low levels can be challenging.
Performing regular Varroa mite counts, using methods like alcohol washes or sugar rolls, is the most reliable way to assess infestation levels. Early detection and appropriate treatment, such as with Apivar strips, are vital to prevent colony decline.
Importance of Monitoring Varroa Levels
Consistent Varroa mite monitoring is paramount for successful beekeeping and maintaining healthy colonies. Relying solely on treatment, even with effective products like Apivar strips, without understanding infestation levels is a flawed approach. Mite populations fluctuate throughout the year, and treatment timing must be precise for optimal results.
Regular monitoring allows beekeepers to track mite buildup, assess the effectiveness of previous treatments, and make informed decisions about future interventions. Tools like Véto-pharma’s EasyCheck simplify the monitoring process, providing quantifiable data on mite loads.
Ignoring monitoring can lead to undetected infestations, allowing mite populations to reach damaging levels, weakening bees and spreading viruses. Proactive monitoring enables timely application of Apivar, preventing significant colony losses and ensuring a thriving apiary. It’s a cornerstone of responsible beekeeping practice.
Apivar Strip Application Instructions
Apivar strips are applied between brood frames, utilizing a toothpick, match, or triangular tag for suspension, ensuring proper dosage—two strips per brood box.
Timing of Application: Fall and Spring
Apivar treatment timing is crucial for effective Varroa mite control. The most common and recommended application period is after honey supers are removed in midsummer to early fall. This allows for treatment without risking honey contamination.
Applying Apivar in the fall targets mite populations before they reproduce within capped brood cells, significantly reducing winter mite loads and improving colony survival. However, Apivar is also suitable for spring use, applied before adding honey supers for the season.
A critical post-treatment rule is observing a 14-day withdrawal period. This means you must wait at least 14 days after removing the Apivar strips before placing any honey supers back on the hive, guaranteeing honey safety for consumption. Strategic timing maximizes treatment efficacy and minimizes potential risks to honey production.
Dosage: Two Strips Per Brood Box
Apivar dosage is directly related to the size of the brood box within your hive. The standard and consistently recommended dosage is two strips per brood box. This ensures adequate amitraz concentration to effectively target Varroa destructor mites throughout the colony’s developing brood.
Regardless of whether you are treating a single-deep, double-deep, or larger hive configuration, maintain the two-strip-per-box rule. Package sizes of Apivar – available in 4, 12, or 60 strip quantities – are designed to accommodate this dosage requirement for varying numbers of colonies.
Accurate dosage is paramount for successful mite control. Underdosing can lead to treatment failure and the development of resistance, while overdosing isn’t necessary and doesn’t provide additional benefit. Always adhere to the two strips per brood box guideline for optimal results.
Strip Placement: Between Frames
Apivar strips are designed for simple and effective placement directly between the frames within the brood box. This positioning maximizes exposure to the bees as they move throughout the hive, ensuring thorough contact with the amitraz treatment. Avoid placing strips on the top bars or directly against honey supers.
The ideal location is typically in the center of the brood nest, where bee traffic is highest. Ensure the strip hangs freely, allowing bees to walk across both sides. Proper placement facilitates effective mite control by allowing for consistent distribution of the active ingredient.
Avoid any manipulation that could cause the strip to tear or break. Maintaining the strip’s integrity is crucial for delivering the correct dosage. Consistent placement between frames, throughout the brood box, is key to successful Varroa mite management.
Hanging Methods: Toothpick/Match or Triangular Tag
Apivar strips offer two convenient hanging methods for easy application within the hive. The most common technique involves utilizing a toothpick or match. Simply insert the toothpick or match through the pre-cut hole in the strip and then secure it between the top bars of the frames.
Alternatively, each strip is equipped with a pop-up triangular tag. This tag allows for direct attachment to the top of the frame, providing a secure and stable hanging point. Both methods ensure the strip hangs freely, allowing bees to make contact with both sides.
Regardless of the chosen method, ensure the strip is firmly attached to prevent it from falling into the brood nest. Proper suspension is vital for consistent Varroa mite control and optimal treatment effectiveness.
Avoiding Strip Cutting
Apivar strips are specifically designed for full-strip application and should not be cut or divided unless explicitly instructed within the product information leaflet. Altering the strip’s integrity compromises the controlled release of amitraz, the active ingredient responsible for effective Varroa mite control.
Cutting strips can lead to inconsistent dosage levels within the hive, potentially resulting in sub-optimal treatment outcomes and the possible development of mite resistance. Maintaining the strip’s original form ensures each colony receives the precise amount of active ingredient needed for successful varroatosis management.
Always adhere to the recommended dosage of two strips per brood box. Following these guidelines maximizes treatment efficacy and minimizes the risk of inadequate mite control. Prioritize full-strip application for reliable and consistent results.
Post-Treatment Considerations
Following Apivar treatment, a 14-day withdrawal period is crucial before adding honey supers, ensuring no residues contaminate the honey harvest.
Withdrawal Period: 14 Days Before Honey Supering
A critical aspect of utilizing Apivar strips effectively involves adhering to a strict 14-day withdrawal period. This timeframe is absolutely essential to ensure the complete removal of amitraz residues from the honey and wax within the hive before any honey supers are added for honey production. Failing to observe this period could result in honey contamination, rendering it unsuitable for consumption and potentially violating food safety regulations.
The 14-day window allows sufficient time for the bees to process and eliminate any remaining traces of the active ingredient. Beekeepers must meticulously record the date of Apivar strip removal to accurately calculate when honey supers can be safely placed on the hive. Prioritizing this precaution safeguards both the health of consumers and the integrity of the honey product. Always consult the product label for the most up-to-date and specific guidelines.
Monitoring After Treatment
Post-treatment monitoring is a vital step in assessing the efficacy of Apivar and ensuring continued Varroa mite control. Simply applying the strips isn’t enough; diligent follow-up is crucial.

To ensure maximum efficacy, unopened packages should be stored in a cool, dry environment, shielded from direct sunlight and extreme temperatures. Ideal storage temperatures range between 40°F and 80°F (4°C and 27°C). Avoid exposure to moisture, as this can compromise the active ingredient, Amitraz, and reduce the strip’s effectiveness.
Once opened, any unused strips should be resealed in an airtight container, alongside a desiccant packet to absorb any potential moisture. It’s crucial to keep Apivar out of reach of children and pets, and away from food and feed sources. Following these storage recommendations guarantees that the Apivar strips retain their potency, delivering optimal Varroa mite control when applied to your valuable bee colonies.
Resistance and Alternative Treatments
Varroa mite resistance to Amitraz is a growing concern, leading beekeepers to explore alternatives like Oxalic Acid and, increasingly, Bayvarol treatments.
Varroa Mite Resistance to Amitraz
Amitraz, the active ingredient in Apivar, has been a cornerstone of Varroa mite control for many years. However, increasing reports and research indicate a concerning trend: the development of resistance within Varroa destructor populations. This resistance isn’t uniform, varying geographically and between colonies, but its presence necessitates vigilant monitoring and proactive management strategies.
The mechanisms behind this resistance are complex, potentially involving mutations affecting the mite’s metabolic pathways or increased detoxification capabilities. Repeated and consistent exposure to Amitraz, particularly through improper application or incomplete treatment cycles, can accelerate the selection of resistant mites. Beekeepers observing treatment failures, even when following label instructions, should suspect resistance and consider alternative control methods.
Early detection of resistance is crucial. Monitoring mite drop post-treatment, alongside regular assessments using tools like Véto-pharma EasyCheck, can provide valuable insights. Rotating miticides with different modes of action, and integrating non-chemical control methods, are essential for mitigating the risk and preserving the effectiveness of available treatments.
Rising Popularity of Oxalic Acid Treatments
Oxalic acid treatments are experiencing a surge in popularity among beekeepers as a complementary and alternative approach to Varroa mite control, particularly in light of growing concerns about Amitraz resistance. Available in both strip and vaporization forms, oxalic acid offers a different mode of action, making it effective against mites that may have developed resistance to other miticides like Apivar.
The appeal of oxalic acid lies in its relatively low toxicity to bees when applied correctly, and its ability to kill phoretic mites – those not currently embedded in capped brood cells. This makes it particularly effective during periods of broodlessness, such as late fall or early spring. However, proper application is critical, as incorrect dosages or timing can harm the colony.
Many beekeepers now integrate oxalic acid into their Varroa management plans, often using it in conjunction with Apivar to provide broader spectrum control and reduce the selection pressure for resistance. This integrated approach is becoming increasingly recommended by experts in the field.
Comparison with Bayvarol
Bayvarol, like Apivar, is a commonly used Varroa treatment, but utilizes a different active ingredient: flumethrin. While both are effective, beekeepers often compare their characteristics based on efficacy, ease of use, and potential for resistance development.
Historically, both Bayvarol and Apivar have been popular choices, however, recent trends indicate a decline in Bayvarol usage, with more beekeepers leaning towards Apivar. This shift may be attributed to concerns about Bayvarol’s performance in certain regions and reports of mites developing resistance to flumethrin.
Apivar, containing Amitraz, generally demonstrates consistent efficacy when applied correctly, and its application process is considered straightforward. Both treatments require careful adherence to dosage instructions and withdrawal periods before honey supering. Ultimately, the choice between Bayvarol and Apivar often depends on regional mite populations and individual beekeeper preferences.
