Beekeeping involves various instances where you may need to feed your bees, such as when you move them to a new location or during late season swarming. It is crucial to know how to feed raw sugar to bees safely, as the right kind of sugar is key to preventing nosema and bee sickness. In this guide, we will explore the best methods for feeding your bees sugar during beekeeping.

Feeding Honey Bees with Raw Sugar

During beekeeping, you can provide honey bees with either dry or wet white table sugar. However, it’s important to note that dry sugar is difficult for bees to digest since it is in crystal form. Bees typically gather nectar and convert it into a liquid form. When sugar is dry, bees won’t utilize it, and it will remain in the hive. Some beekeepers recommend using superfine sugar as it is easier for bees to collect when in liquid form. Alternatively, you can create sugar bricks, which are denser versions of clumped dry sugar, eliminating the need for cooking.

While it may be tempting to feed honey to your bees, it’s crucial to remember that it is not recommended for the health of your colony. Honey, although suitable for human consumption, can contain disease-causing bacteria and attract pests. Additionally, honey can carry diseases like American foulbrood, European foulbrood, chalkbrood, and nosema fungal disease. To mitigate these risks, it is best to use disease-free honey.

The Upside-Down Jar Method

The most common method for feeding raw sugar to bees is by using an upside-down jar with a perforated lid. The perforated lid creates a vacuum seal that prevents the syrup from leaking out while allowing bees to access the syrup through the perforations. To create the lid, make small holes using a nail or brad. It is important to ensure that the syrup doesn’t contain traces of honey or essential oils, as these substances can attract other bees and yellow jackets.

Preventing Crystallization and Contamination

One important consideration when feeding raw sugar to bees is the possibility of crystallization within the hive. If sugar remains in the combs for more than a day, it can contaminate the honey. Additionally, sugar water solutions can become harmful and even lethal to bees if not properly cooled. Always ensure that the sugar water solution has cooled down to room temperature before feeding it to your bee colonies. If you are concerned about your bees’ health, you can consider adding some pollen to the syrup.

Choosing the Right Sugar

When feeding your bees, you have the option to use either raw or refined sugar. Using unrefined sugar can be harmful to bees as it may contain molasses, which is toxic to them. However, molasses-containing white sugar is cheaper and doesn’t provide any additional benefits to bees. Alternatively, you can try coconut or palm sugar, both of which have high mineral content. Unlike white sugar, coconut and palm sugar contain significant amounts of molasses and are less likely to cause digestive issues in bees. Stevia, a glycoside by-product derived from pressing the leaves of a plant, is another option to explore.

Sugar Requirements for Bee Colonies

A colony of 50,000 bees requires approximately 1.1 liters or 2 pounds of 50 percent sugar syrup per day. This amounts to 700 pounds of sugar per year. Despite most nectars having less than half a percent sugar content, large colonies still require a substantial amount of food. To achieve good results, it is advisable to start feeding your bees as early as possible.

Ensuring Bee Safety

If you are a beginner beekeeper and wish to feed your bees raw sugar, here are some tips to follow for their safety. Firstly, use a vacuum-sealed plastic jar with a perforated lid that allows bees to access the syrup through their proboscis. Create tiny holes in the lid using a 1/16th-inch drill bit or small nail. It is important to note that sugar syrup can be toxic to bees, and feeding them raw sugar during beekeeping is not recommended.

To keep bees safe, you can mix the sugar with water or corn syrup. Bees cannot digest syrup alone as it contains water. Instead, prepare sucrose slabs and place them under the inner cover to minimize robbing. Adding essential oils such as spearmint and lemongrass to the syrup can help keep mites and mold at bay. The added flavor also aids bees in locating the syrup easily.

When feeding raw sugar to bees, it is essential to keep it in a jar with proper insulation. Bees will not consume syrup below 50 degrees F or 10 degrees C. In addition to using a container with an insulated lid, remember to remove the super before feeding honey to the bees. As a general rule, avoid feeding raw sugar to your bees during beekeeping.

Debunking Myths

There are some misconceptions regarding feeding sugar water to bees. Contrary to popular belief, sugar water is not harmful to bees if fed to them only once. However, it is crucial to carefully read and follow instructions to ensure their well-being. If done correctly, adding sugar water to your bird bath is perfectly safe to attract bees. If you are uncertain about whether you can safely feed your bees with sugar water, you can try leaving a bowl of sugar water outside to attract them.

Sugar Syrup vs. Honey and Pollen

The best source of sugar for bees is sucrose. Typically, sugar comes in white granules containing 70-80% sucrose. However, some sugars may be contaminated with chemicals that can be dangerous for bees. To avoid this, it is recommended to use refined sugar. Alternatively, you can try agave nectar or maple syrup, which are derived from sap.

It’s important to note that sugar syrup is only part of the food required for bees to survive. If your bees are consistently collecting pollen, sugar feeding may not be necessary. Moreover, without sufficient pollen intake, bees are unlikely to produce brood, so they won’t readily accept pollen substitutes. Therefore, it is essential to understand the distinctions between honey and pollen.

Feeding Dry Sugar to Bees

How to feed raw sugar to bees during beekeeping

Feeding dry sugar to bees can be accomplished through various methods. Some beekeepers simply dump the sugar at the back of the hive, while others place it on the inner cover. Another approach involves placing a piece of newspaper over the top bars and putting clumped sugar on top of the newspaper. Alternatively, you can create sugar bricks, which are dense, clumped sugar formations. Whichever method you choose, ensure that the bottom board of your hive is solid, preventing sugar from falling through any gaps.

Feeding dry sugar to bees is particularly useful for beekeepers looking to supplement winter stores and prepare for potential honey shortages. While this method is not harmful to bees, it can disrupt their colony. Raw sugar carries a higher risk of being consumed by bees due to poor digestion within the colony.

Another simple method is to feed dry sugar on the top bars of the hive. The sugar can be poured directly onto the bars or placed outside the hive. Sugar bricks are easier to handle than fondant. If you prefer making your own fondant, you can find easy and effective recipes on YouTube. Additionally, there are other options available, such as sugar bricks or dry sugar.

If you do not have access to a mixing bowl, you can measure the contents of a pint container before adding sugar. A pint container filled with water and white sugar will weigh close to a pound. It is crucial to dilute the sugar correctly, as failure to mix it with water may introduce harmful bacteria to the hive and risk the bees’ well-being.

While there is no standard ratio of sugar to water, many beekeepers use different mixtures to stimulate their bees. In the spring, a 1:1 sugar to water mixture is easier to transport and keeps better than a 2:1 mixture. In the fall, bees can handle any sugar to water ratio. However, a 5:3 ratio is preferred in the fall as it dissolves more conveniently compared to a 1:1 sugar to water ratio.

To increase moisture levels in the hive, you can also place feeders on the hive top. However, it is crucial to remove the feeders once bees stop taking feeds, especially when temperatures drop. Bees cannot distinguish between a feeding tube and other food sources if they are not covered properly. Consequently, they may dehydrate the sugar and store it as honey.

Some beekeepers choose to feed their bees with honey instead of sugar syrup. Honey generally has a lower pH than sugar syrup and is more easily digested by bees. A single piece of dry sugar can last for years, making it a great alternative to other feeding methods that don’t require granulated sugar.

Feeding raw sugar to bees during beekeeping can be done in various ways, but it is important to prioritize their safety and well-being. Dry sugar and sugar syrup can both be used, depending on the situation and your bees’ specific needs. Remember to use the appropriate equipment, follow recommended practices, and consider the differences between honey and pollen when providing supplementary feeding to your bees.


Is raw cane sugar OK for bees?

Raw cane sugar is generally safe for bees when fed in moderation. Bees can digest sucrose, which is the primary sugar found in raw cane sugar. However, it is important to note that raw cane sugar may contain impurities or chemicals that can be harmful to bees. Therefore, it is recommended to use refined sugar instead of raw cane sugar to ensure the bees’ well-being.

What sugar is toxic to bees?

Why should brown sugar or unrefined sugar not be fed to bees?

Brown sugar or unrefined sugar should not be fed to bees because they contain impurities that can be harmful to the bees’ health. Brown sugar undergoes less refining and retains more of the molasses and impurities from the sugarcane. These impurities can disrupt the digestive system of bees and potentially lead to health issues. Therefore, it is best to stick to using refined white sugar when feeding bees.

What happens if you feed bees brown sugar?

Feeding bees brown sugar can have negative consequences on their health. Brown sugar contains higher levels of impurities compared to refined white sugar. These impurities can potentially harm the bees’ digestive system and overall well-being. Additionally, the molasses content in brown sugar may cause fermentation, leading to an increased risk of mold growth in the hive. Therefore, it is advisable to avoid feeding bees brown sugar.

What is the difference between honey, raw sugar, and cane sugar?

Honey is a natural sweet substance produced by bees from the nectar of flowers. It contains a variety of sugars, enzymes, and trace elements, providing bees with essential nutrients. Raw sugar is minimally processed sugar that retains some impurities from the sugarcane. Cane sugar, on the other hand, refers to sugar derived from sugarcane and can be refined or unrefined. While honey is a natural food source for bees, raw sugar and cane sugar should be used cautiously and preferably in refined form to avoid harmful impurities.

What is highly toxic to honey bees?

Several substances can be highly toxic to honey bees, including certain pesticides, insecticides, and chemicals. Neonicotinoid pesticides, in particular, have been shown to have detrimental effects on bee populations. It is crucial to use bee-friendly and environmentally safe practices when dealing with potential toxins to protect honey bees and their colonies.

Can bees get high on sugar?

Bees do not get “high” on sugar. However, they have a natural attraction to sugary substances due to their need for energy. Bees have a specialized proboscis that allows them to feed on nectar from flowers, which contains natural sugars. This behavior is an essential part of their survival and the pollination process. While bees may exhibit an enthusiastic response to sugar, it is not equivalent to experiencing a “high” as humans do.

Can you feed maple syrup to bees?

Maple syrup can be fed to bees as a sugar substitute in certain situations. However, it is important to note that maple syrup has a higher moisture content compared to sugar syrup, which can lead to fermentation and mold growth if not used properly. If you choose to feed bees maple syrup, it is recommended to mix it with an appropriate ratio of water to achieve the desired consistency and prevent fermentation.

What food is the best feeding substitute for bees?

Sugar syrup, made by dissolving refined white sugar in water, is generally considered the best feeding substitute for bees. This sugar syrup closely resembles the natural nectar bees collect from flowers and provides them with the necessary energy and carbohydrates. It is important to use the correct sugar-to-water ratio based on the season and the specific needs of the bees.

Is molasses good for bees?

Molasses is not typically recommended as a food source for bees. While it is a byproduct of sugar production and contains some nutrients, it also has a high moisture content and can lead to fermentation in the hive. Fermentation can create an unfavorable environment for the bees and promote the growth of harmful molds. Therefore, it is best to stick to using refined white sugar or sugar syrup when feeding bees.

Can you feed bees corn syrup?

Corn syrup can be used as an alternative to sugar syrup for feeding bees, but it is generally not recommended. Corn syrup is derived from cornstarch and contains a mixture of glucose and fructose. While bees can digest these sugars, corn syrup may have a higher moisture content than sugar syrup, leading to fermentation and mold issues in the hive. It is safer and more suitable to use refined white sugar or sugar syrup as a bee food substitute.

When should you not open a beehive?

It is generally advised not to open a beehive during unfavorable weather conditions such as rain, strong winds, or extreme temperatures. Bees are sensitive to environmental changes, and opening the hive during inclement weather can disrupt their temperature and humidity regulation, as well as increase the risk of stress or injury to the colony. Additionally, during certain times of the year, such as the winter months when bees are in a cluster for warmth, it is best to avoid disturbing the hive unless absolutely necessary.

Can you overfeed bees?

Yes, it is possible to overfeed bees. Overfeeding can lead to several issues within the hive, such as excessive moisture, increased risk of fermentation, and potential mold growth. Additionally, overfeeding can disrupt the natural foraging behavior of bees and reduce their motivation to collect nectar from natural sources. It is important to provide supplementary feed in moderation and ensure a balanced diet that includes natural nectar sources when available.

What is 1 to 1 sugar water for bees?

A 1 to 1 sugar water ratio refers to a mixture of equal parts, by weight or volume, of refined white sugar and water. This ratio is commonly used for feeding bees during periods of nectar scarcity or when they require additional nourishment. The 1 to 1 sugar water provides a balanced source of carbohydrates for the bees and closely resembles the sugar content found in natural flower nectar.

What is the honey bee’s worst enemy?

The Varroa destructor mite is considered one of the worst enemies of honey bees. These parasitic mites attach themselves to honey bees and weaken them by feeding on their hemolymph (the bee’s equivalent of blood) and transmitting viruses. Varroa mites are a significant threat to honey bee populations worldwide and require ongoing management and treatment to protect the health and survival of bee colonies.

What is the number one killer of honey bees?

While there are various factors that contribute to honey bee decline, including habitat loss and pesticide exposure, the Varroa destructor mite is often regarded as the number one killer of honey bees. These mites not only weaken individual bees but also transmit harmful viruses throughout the colony, ultimately leading to the collapse of the hive if left untreated.

What is a honey bee’s biggest predator?

Among the many predators that honey bees face, the Asian giant hornet (Vespa mandarinia) is considered one of their largest threats. These hornets are significantly larger than honey bees and have been known to attack and decimate honey bee colonies. However, it is important to note that the Asian giant hornet is primarily found in certain regions, such as East Asia, and may not be a predator of honey bees in all areas.

Should you give bees sugar water?

Providing sugar water to bees can be beneficial, especially during periods of nectar scarcity or when bees require additional nourishment. Sugar water serves as a supplemental food source and can help sustain the bees’ energy levels and overall health. However, it is important to use the correct sugar-to-water ratio and offer it in moderation, ensuring that the bees still have access to natural forage when available.

Why do bees go after sugar?

Bees are naturally attracted to sugar because it serves as their primary energy source. Nectar from flowers contains sugars, primarily sucrose, which bees collect and convert into honey. Sugar provides bees with the necessary carbohydrates and energy they need for various activities, including foraging, nest building, and maintaining their bodily functions. The attraction to sugar is an instinctual behavior that aids their survival and the pollination process.

Why are my bees drinking so much sugar water?

If your bees are consuming a significant amount of sugar water, it may indicate a shortage of natural nectar sources in their foraging area. Bees rely on nectar as their primary food source, but when nectar is scarce, they will readily consume sugar water as a substitute. To ensure their well-being, it is important to provide an adequate supply of sugar water during these periods of scarcity and continue monitoring the hive’s food stores.

Why are my bees not eating sugar syrup?

There could be several reasons why your bees are not consuming sugar syrup. One possibility is that they have sufficient natural nectar sources available, making the sugar syrup less appealing to them. Additionally, environmental factors such as extreme temperatures or unfavorable weather conditions may discourage bees from taking in sugar syrup. It is essential to assess the hive’s overall health and forage availability to determine the specific reason for their lack of interest in sugar syrup.

When should I stop feeding bees syrup?

The timing for stopping syrup feeding depends on various factors, including the local climate, availability of natural nectar sources, and the strength of the colony. As a general guideline, syrup feeding is typically halted when there is a consistent and abundant natural nectar flow in the area. This usually occurs during the peak of the flowering season. Observing the bees’ behavior and monitoring the hive’s honey stores can help determine when it is appropriate to stop syrup feeding.

Why can’t you feed bees honey?

Feeding bees honey from unknown sources or external origins can introduce the risk of spreading diseases and pests within the hive. Honey obtained from sources other than the bees’ own production may carry pathogens, including the spores of the American Foulbrood (AFB) bacterium or other honey bee diseases. To prevent the transmission of diseases, it is best to avoid feeding bees honey from outside sources and instead focus on providing them with suitable sugar syrup or other recommended food substitutes.
