The 6 Best Oxalic Acid Vaporizers Against Varroa Mites

One of the most common and destructive pests you’ll encounter as a beekeeper is the varroa mite. And the only thing that can effectively counter it, is by using the best oxalic acid vaporizer.

Varroa mites are only found in honey bee colonies and are a major contributor to colony collapse around the world. They are an incredible hazard to any hive, and as a beekeeper, you’ll need to invest in the best protection to safeguard your colony.

Oxalic acid is the prime protection beekeepers use against varroa. It’s a naturally occurring acid found in many plants and foods. 

And when concentrated, it is toxic to varroa mites. Honeybees have a high tolerance to it and are undisturbed. Many beekeepers use oxalic acid vaporizers, which heat the acid into a mist that coats their honeybees. This in turn treats the hives and removes the parasites in one session.

The best vaporizers will be both easy to use and durable, becoming life-long tools in your beekeeping arsenal. They’ll also heat up quickly and safely, to vaporize oxalic acid into a mist.

Frequently Asked Questions

How do oxalic acid vaporizers help bees? Is it safe?

Oxalic acid is used in the treatment of Varroa mites in bee colonies, one of the most dangerous and destructive parasites in beekeeping.

Oxalic acid is a naturally occurring acid found in plants. It’s an acid that bees tolerate quite well, but which is very toxic to varroa mites. For that reason, you can treat your hives with oxalic acid with great peace of mind your hives won’t become distressed.

That said, always follow the recommended amount of oxalic acid per your vaporizer’s instructions.

Varroa mite in bee hive

How do you mix oxalic acid for bees?

Many beekeepers will feed their bees with a sugary solution before vaporizing so that the bee’s stomachs will be full and they won’t ingest any of the treatment.

How often can you treat bees with oxalic acid?

The best time to use oxalic acid is in early spring and late autumn when there are no honey supers on the hive.

At what temperature does oxalic acid vaporizer?

The typical temperature to aim for is between 150 °C – 180 °C (302 F – 356 F). Any higher and oxalic acid will turn into a volatile and harmful acid to bees.

Do I need to wear any protection?

Yes, always wear protective gear when working with and administering oxalic acid. This includes but is not limited to: goggles, gloves, protective clothing (to avoid burns), and either a half-mask or full mask,

For those needing pure airflow and who are vulnerable to respiratory problems, avoid poorly ventilated areas and consider wearing an air-purifying mask. 

Can you eat honey treated with oxalic acid?

Simply put, no – you should not eat honey that may have traces of oxalic acid. For this reason, beekeepers often only use oxalic acid vaporizers when there is little to no honey present in the hive, for example during the late autumn (when honey supers have been removed), and early spring.

When should you use oxalic acid vaporizers?

As well as late autumn and early spring, you should also consider the temperature outside and time of day when using a vaporizer. 

You want as many of the hives to be inside when treating them, to maximize coverage. Ideally, cold days when bees are dormant inside work best.

How often should you use an oxalic acid vaporizer?

You should only treat your hives for varroa mites in this fashion once per year.

Oxalic Acid Vaporizer Buying Guide

As we all know, treating beehives for varroa mites is pivotal to a healthy colony. For that reason, beekeepers invest in the best oxalic acid vaporizer to help.

Here are some things to consider when choosing which vaporize is right for you:

When exactly should you buy an oxalic acid vaporizer?

Especially if you’re a beginner, you may be wondering when you need to buy an oxalic acid vaporizer. What time of the season should you be preparing for?

Beekeepers treat varroa during two specific times of the year; late autumn and early spring. This is for two reasons:

  • Honey – no honey supers will be put on hives at this time. Oxalic acid will affect honey, making it unsuitable for human consumption.
  • Hibernating – more bees will be inside the hive and thus be affected by the treatment.

Durability

Vaporizers must be incredibly hardy and durable if they are to sustain continued use and high temperatures. For that reason, only consider products made of high-quality metal material and which have reinforced, thick cords.

The handle is also an important factor to consider. Ensure that handles are comforting, supportive and won’t absorb the heat from the tool.

Lastly, any additional accessories such as battery clips should be made of suitable materials, such as copper or rubber-plated, to improve conductivity.

Heating, temperature, and time

Ensure your prospected vaporizer reaches optimal temperatures for vaporization to occur. Whilst products may vary on their advice, the typical range to aim for is around 180 °C (356 F).  

Many of the best products work within a few minutes to create the desired mist and may require a cooling-off period in between hives.

Whilst some vaporizers may be temperature controlled or include thermostats, others rely simply on timing. Ensure you have a stopwatch nearby to rely on.

Lightweight

As with any tool that requires precision, you’ll want to consider its weight. Many of the best vaporizers will be lightweight, allowing you to hold the tool and most importantly, manoeuver it effectively. 

Aluminum and stainless steel are two metals often used in producing vaporizers because they’re easy to carry, but still, retain sturdiness and strength.

Hive type matters

You should always consider your hive when choosing the best oxalic acid vaporizer.

When beekeepers administer oxalic acid through vaporization, they may seal the hive for a short period to maximize its effectiveness. For this to work, however, your hive box must be in prime physical condition, with no weathered holes or damage.

Secondly, consider the size of your entrance – can the tool be inserted comfortably? Many vaporizers give exact measurements so that you can buy with confidence that the tool will fit traditional-sized hives without the need for any modifications.

You should never use oxalic acid vaporizers in synthetic, plastic hives. It goes without saying, but the extreme temperatures the vaporize reaches will surely damage the hive beyond repair. You can use an alternative method, known as trickling – although more bees may become harmed by this method.

Screened bottom board

Many beekeepers use a screened bottom board in their hive to help with parasite controls, including varroa mites. Screened boards allow debris such as varroa to fall off the bee, and not allow other pests to crawl back up.

For this reason, beekeepers can examine underneath hives throughout the year and make observations on if mites have fallen off and how bad an infestation is.

How does it charge?

Powering your tool is a major consideration. Without the proper means, you won’t be able to use it! Many of the best oxalic acid vaporizers are compatible with traditional car batteries, lawnmowers, and more.

The cords matter

Next, you should consider how generous the cord length is for your vaporizer. After all, if it’s connected to a large battery, you want to ensure you can reach your hive/s comfortably. Always check your power cord for damage before using the vaporizer.

Because the wiring is often the most vulnerable part of a powered tool, you should consider how the cord is made. Is it extra thick? Does it have a protective coating? Are clips included to help keep it organized? Picking a superior cord will undoubtedly extend the shelf life of your vaporizer.

Fully assembled and simple to use

The best vaporizers will arrive fully assembled and require little to no alterations or customizations to perform their job. They will also be incredibly straightforward to use and include detailed instructions. 

Many vaporizers can be used by simply inserting them into the hive entrance for a short period, sealing the hive, and then removing the tool. You shouldn’t be expected to move or separate frames, remove hive boxes or alter your hive in any permanent way.

Scoops and other accessories

Many vaporizers will include a scoop to help you measure the precise amount of oxalic acid you need per treatment. It’s advised to use these consistently to ensure the mixture you’re developing is appropriate to your needs.
