These mites are still around but it’s the varroa that are keeping all beekeepers on high-alert for their unwanted presence, so we’re here to offer all of the information required to keep you and your bees safe.

Varroa Mite Infestations

Varroa mite infestations can be detected on the body surface of your bees, they are known to feed on the blood and cause parasitism, which basically means that your bees will live shorter lives and not be as productive outside and inside the hive.

The mites that you can’t see, the ones that many beginners are unaware of, cause the most damage to your colonies because they feed on the young bees in the cells of the bee larva, deforming the baby bees and also spreading viruses throughout the hive.

It doesn’t take a scientist to realize that this can quickly wipe out your bee colony and leave you with nothing!

In all honesty, it’s an ongoing battle that has no exact science in preventing these mites from causing havoc in your hive. There are, however, certain methods that work better than others and we’ll be looking into them and picking out the options that will give you the best chance of success in fighting these mites.

Overall, it’s a case of forming a plan that works for you and sticking to it, with the hope of keeping the number of mites in your hive as low as possible.

When To Start Varroa Mite Treatment?

Firstly, we want to confirm again that varroa mites are likely to be present in your beehives, that’s just a natural fact that we must accept, even if they are such a big threat to our beloved bees.

The threat only comes true when the level of mites get too high, your bee colony can cope with a small number of mites, so it’s our job to keep this level low before persuing varroa mite treatment. Aiming for 0% mites is a very big ask and something that might drive you crazy in the long run, just remember that you are trying to keep the level low.

It’s when you start to notice a varroa mite infestation, this would be a clear sign that you have to start and take action to reduce the growing varroa mite populations quickly.

Determining the level of mites is really something that each beekeeper needs to work out for themselves, However, there are some rough guides and things to look out for, for example, bees with deformed wings is a big sign of varroa mite infestations, and bees struggling to fly in and out of the hive is another sign.

You can use the following method to roughly estimate the level of mites in your hive, take a sample of your hive and count the number of mites and divide it by the number of bees, then multiply by 100 to get your percentage.

So, for example, 10 mites with 500 bees would give you roughly a 2% infestation. It is widely suggested that if your infestation is between 2-5% then some action needs to be taken against the mites. Anything over 5% shows a definite sign to start treatment straight away before your varroa mite infestations get out of hand.

Treatment Tips and Useful Information

There are four types of methods to choose from for controlling varroa mites, the first three are physical, behavioral and mechanical. These methods are not enough to be used on their own but can help in the fight against the varroa mite infestations, here are some of the more popular choices:

  • Screened bottom boards (instead of solid so mites can fall to the floor)
  • Drone-brood trapping where mites are enticed to a certain area of the hive
  • Dusting bees with sugar or talc (mites are more likely to slip off the back of bees)

The last method is chemical and has been proved to remove the majority of the mites from your hive. This chemical method is, of course, the most popular as it tends to be the most effective.

You can choose from synthetic or naturally occurring chemicals, they have all been proven to work but using them incorrectly could result in mite resistance, so you must learn how to apply them in the correct manner.

Chemical – Synthetic Form

  • Pyrethroid insecticide in strips
  • Organophosphate insecticide in strips
  • Manley’s Thymol Crystal as food

Chemical – Natural Form

  • Formic Acid as vapor or pads
  • Powdered Sugar (sprinkled on bees)
  • Essential Oils (mint, lemon, thyme)
  • Sugar Esters
  • Oxalic Acid as vapor
  • Mineral Oil as vapor or direct application
  • Natural Hops in strips


The big idea to remember here is not to wait until you start noticing these little red mites inside of your hives, for some this will be too late and your colony might already be jeopardized, so it’s best to take action early and keep the level of mites in your hive as low as possible. The earlier you start, the more chance you have of beating these little critters!

We’ve provided some more information on the different chemicals used in these varroa mite treatments, the more knowledge you have, the better decision you can make when creating your treatment plan.

Oxalic Acid

Oxalic acid (scientifically known as Oxalic acid dihydrate, or organic acid) can be used in two different ways to control varroa mites – one as a drizzle or the other as a fumigant.

  • The drizzle (or drip) method involves mixing the oxalic acid with sugar water, this mixture is then poured over your bees. Bees cluster together during Autumn/Winter time, making it an ideal time to carry out the drizzle treatment. It is recommended to only use the drizzle method twice a year as the acid is corrosive to the bees bodies
  • The vaporization method is a beekeeper favorite that gives great results every year, ideally used in the warmer months. You place a small amount of oxalic acid on the end of the vaporizer stick and slide this into the hive. The stick heats up to vaporize the acid crystals, and the crystals then begin to reform as the vapor starts to cool down inside the hive. The honey bee colonies then expose the crystals to the varroa mites by moving the crystals around the hive. It’s also good practice to cover your hive with a cloth for 10 minutes after treatment, this allows for maximum exposure inside the hive

Formic Acid

Formic acid can also be used as a fumigant (similar to the oxalic acid), however, this type of acid is capable of killing mites in capped broods whereas oxalic acid is not. This means that formic acid is perfect for treating your hives and being effective during the warmer months of the year.

Some beekeepers have experienced queen loss and reduced brood production after formic acid treatment, so you should work carefully and not overuse the acid to begin with.

Apistan (fluvalinate)

Apistan is a substance that has been used for many years to control mites, it is applied as strips that have been chemically treated and kills the mites on contact.

However, there have been reports of chemical residue in the wax, so do be careful if you use this. There are many other alternatives that work better so we recommend staying away from this if possible.

Apivar (amitraz)

A synthetic miticide that is widely used to kill mites on contact. Placing strips near the brood is advised but using honey supers is restricted for at least two weeks after the treatment.

Some reports have shown low levels of chemical residue on the wax and honey, and the mites have been known to develop resistance to this chemical. However, on the whole, Apivar has provided quick and effective results for many beekeepers.

Apiguard

Apiguard acts a fumigant that has shown effective results when killing off mites, it comes as a gel that contains the natural oil, Thymol.

However, being a natural treatment means that this option is temperature sensitive, only to be used in temperatures between 59-105 Fahrenheit.

Final Words For Varroa Mite Treatment

Varroa mites are a big pain but if you understand how to use the various treatments and form a plan throughout the beekeeping season, then you will be able to keep them under control. You need to be proactive when fighting against these critters and often people leave it until it’s too late.

Hopefully, we’ve given you enough information for you to form your own treatment plan, it can start to get quite costly if you manage multiple hives so make sure to do the calculations and find the right treatment choice for your setup.

If you are unsure about using any of the chemicals then seek advice with a local professional or any other experienced beekeeper in your area.

But for now, until someone finds a definitive treatment, it’s going to be a case of carrying on with the recommended treatment options, that have proven to remove the majority of mites, and remember, stick to the plan and keep those little beasts at bay! Good luck!
