Essential Oils and Honey Bee Health

Honey bee colonies live in the natural world and are exposed to numerous pests, pesticide etc. We want to have healthy bee colonies. Using essential oils for honey bees has become a very popular way to promote bee health. While these products are not a cure for the issues facing our colonies, many people believe they can be a positive influence. This is especially true since the increase in bee problems related to varroa mites. However, the use of anything in the hive should be done with caution. Can the use of an essential oil help your colony?

Beekeeping has seen a surge in popularity in the last 30 years. Many of these new beekeepers are concerned about the effect of pesticides in our environment.

They have a passion for finding non-chemical ways to help bees. Can bees be kept in a more natural way?

We see a desire for more natural methods of all aspects of keeping bees . And, interest continues to grow in the use of natural compounds instead of synthetic chemicals.

Varroa Mites Are the #1 Bee Health Problem

I always tell the students in my online beekeeping class that controlling varroa is one of the most important keys to beekeeping success. And, there are many different ways to tackle the bee mite problem.

Instead of mindlessly “going with the flow” and using the easiest conventional method of varroa mite treatments – explore other options too.

But, always check to make sure they are safe and effective. Is using essential oils for mite control a sound- more natural option to hard chemicals?  Maybe.

Mite Infestations Result in Poor Colony Health

Colonies with high loads of varroa mites do not thrive. Unhealthy colonies are much more susceptible to viruses and other problems.

Of course, it is not just mites that take a toll on our bees. Environmental changes and contamination contribute to poor bee health. 

This is not a good environment for developing young bees who are subject to an ever reducing varied diet. A bee colony in poor health is more likely to fail.

Beekeepers are devastated emotionally and financially as they watch colony after colony perish from mites and related health issues. 

In desperation, some try non-approved methods. Some of these are great ideas that are ahead of their time and some can end in disaster. 

Are Essential Oils Safe to Use in the Hive?

In the struggle to keep hive healthy, the idea of using natural oils in your beekeeping program is appealing. They are natural products so we should have few worries, right?

Not exactly, even though these oils are natural products-that does not mean they should be used “willy nilly”. They are powerful compounds and can do great harm when used in the wrong way.

The use of essential oils as a food supplement for honey bees is common in the beekeeping world. 

However, some of the methods of application and many of the oils are not legally approved for use in beehives. 

Then why do beekeepers use them?  Because the bees are sick and beekeepers want to save them.

In the past, most of the approved mite treatments contained toxic substances that accumulate in the wax and honey of the beehive.  These are still around but new alternatives are coming on the market.

How to Use Essential Oils in Beekeeping?

If you decide to try using essential oils in your hives, do your research first and don’t trust the opinion of only one source. (Not even if it is me.. LOL)

  • help in the control of tracheal mites (a lesser mite problem)
  • possible varroa mite reduction
  • help prevent nosema (an intestinal disease)
  • aid in new queen introduction
  • use as a swarm lure
  • keep syrup from becoming moldy.

Honey Bee Mite Control

The most popular oils used in beekeeping are : Thyme Oil, Spearmint Oil and Lemongrass Oil. Some sources recommend Wintergreen Oil, and Tea Tree Oil as well.

Thyme Oil contains thymol.  It assists in control of varroa mites a major killer of honey bee colonies worldwide. The fumes confuse mites and block their breathing pores. Thymol is also active against fungus and somewhat effective in control of tracheal mites.

Spearmint Oil works in the same way as thyme.  It masks the normal scent of the bees (making them harder for mites to locate).  It does not mimic or interfere with normal colony pheromones. 

These important pheromones control activities inside the hive.  We do not want to add anything that will greatly disrupt normal colony life.

Lemongrass Oil for Beekeeping Use

Lemongrass OilThe most popular oil used for honey bees is Lemongrass.  It is  used as  a treatment for pests, a supplement for health boost or as a bait to lure honeybee swarms to traps. 

Lemongrass is antifungal and antibacterial. It does mimic some common honey bee pheromones.  Be careful when using any lemongrass product with weak hives. 

The scent may attract robber honey bees from stronger hives. The weaker colony may not have enough bees to protect themselves resulting in loss of the hive.

Bee Feeding Supplements

If you don’t have the time to make your own essential oil recipes for your bees, you do have a few options that are ready to use.

Honey B Healthy” (HBH) is a popular supplement for improving honey bee colony health. It is a proprietary blend containing essential oils and other ingredients. A small amount of HBH added to sugar water serves as a nutritional boost.

I have used it for years and cannot say enough good things about the product. You will always find a bottle of Honey B Healthy in my equipment shed.

Another popular brand of feed supplement using oils is Pro-Healthy from Mann Lake. It is used in the same way as Honey B Healthy.

These products are often added to sugar water, mixed into pollen patties and added to sugar water for spraying directly on the bees.

Make Your Own Essential Oil Mix For Bees

If you have many honey bee colonies, you can create a similar mixture for your colonies. If you have only a few colonies, it might be better to purchase a mix for honey bees-ready to use.

Most recipes that involve using essential oils for bees will include a sugar water component. It is a well known fact that water and oil doesn’t mix easily.

Getting your oils to disperse well in sugar water is made easier by the use of Lecithin Powder. This powder eases the mixing of your products and does no harm to the bees. Only a small amount is needed so it lasts a long time.

I have tried the homemade Honey b Healthy (copycat) recipe.  I found it difficult to get a perfect blend of ingredients and choose to purchase the name brand product.

How to Use Essential Oils in the Beehive

The most common method of application is mixing the oil recipe into sugar syrup.  This is then fed to the bees.

Be careful when using them in bee sugar water.  Follow recipes, measure carefully. Essential oils are powerful stuff ! I know I am saying this a lot but it is very important to remember.

Many beekeepers spray the mixture (mixed with sugar water) directly on the honey bees. Do this with caution! -don’t chill the bees or spray directly into the cells. I would encourage beginner beekeepers to not spray but feed instead.

Using Pollen Patties With Essential Oils

When used properly, pollen patties that already contain essential oils can be a good choice for the beekeeper.

It is important to keep in mind that pollen patties must be used with EXTREME care in regions that have Small Hive Beetles.

You can make your own protein pollen patties. They can be frozen and used as needed. When to use them and how much to use will depend on your location.

Honey Bee Essential Oil Recipes

Recipe #1 Bee Health Boost

** Blend well – always shake before use – Use 2 tsp of this concentrate to a quart of sugar water feed

Recipe # 2 Health Boost

Blend thoroughly in a blender (5 min).  Pour into ½ gallon jug and add enough water to make 2 quarts.  

Do NOT heat the essential oils.  This will make a concentrate.  Use 1 cup of concentrate to 1 gallon of cool syrup.

Grease Patties and Essential Oils

Grease patties are not as popular as they once were but some beekeepers still use them. A mix of crisco and sugar -they were originally used to combat tracheal mites. 

The addition of essential oils “may” provide some varroa control. Grease patties can be used on hives most of the year. But, they sure are a mess in hot weather! Therefore, the beekeepers who still use them do so mostly in the Winter.

They should not be used when collecting honey for human consumption.  In addition to being messy, patties too may cause problems with honey bee pests.

Final Thoughts on Using Essential Oils for Bee Health

When trying natural oils in beekeeping, use VERY small amounts – most folks add too much product. Proceed with caution.

We do not have solid evidence that the use of essential oils will handle varroa mite issues. But, they may aid bee health in other ways that helps promote productive hives.
