Advice on feeding

Sugar Syrup for Bees – The Optimal Bee Feeding Ratio

A sugar syrup mixture of three parts sugar to two parts water has proven over time to be the most effective bee feed for healthy colonies. This bee feeding ratio provides good stability, the right consistency, and ensures quick uptake by the bees. When you mix sugar syrup for bees, accuracy and cleanliness are essential — even small deviations can spoil the syrup or reduce feed acceptance.

Mixing Bee Feed – What to Watch Out For

When preparing sugar syrup for bees, there are several key points to consider. Because sugar syrup spoils easily, it should always be made fresh. Especially during warm weather, syrup can ferment within a short time if stored too long. Only prepare as much as you plan to feed within the next few days. Cool, hygienic storage will extend the shelf life — but remember: the fresher, the better.

It’s equally important that the feed does not remain in the hive for too long. The bees should consume and store it in the combs quickly. If sugar syrup sits too long in feeders or buckets, mold and fermentation may occur, which can lower feed quality and harm your bees.

When a 1:1 Sugar-to-Water Ratio Makes Sense

A ratio of 1 part sugar to 1 part water creates a thinner bee syrup, mainly used for spring stimulation feeding or comb building. This lighter syrup encourages the queen to lay eggs and mimics a natural nectar flow, helping the colony build up brood earlier. However, this mix is not suitable for winter feeding as it is less energy-dense and perishes faster. In late summer and autumn, beekeepers should return to the 3:2 ratio to ensure long-lasting winter stores.

Avoid Hot Water When Mixing Bee Feed – Prevent HMF Formation

When mixing bee syrup, never use boiling or very hot water. While sugar dissolves faster in heat, it increases the formation of Hydroxymethylfurfural (HMF), a compound that develops when fructose is exposed to high temperatures and is toxic to bees. Studies from the Celle Bee Institute show that bee mortality doubles at only 1 g of HMF per kg of feed compared with clean syrup. Always use cold or lukewarm water, stir thoroughly until the sugar has completely dissolved, and avoid any heating.

Calculating the Right Amount of Bee Feed

The required feeding amount depends on colony size, season, and available stores. With BeeInTouch, you can calculate the bee feeding amount precisely and plan your bee syrup mix ratio efficiently. The “Bee Feeding Calculator” in BeeInTouch takes into account both your colony count and current stores, helping you feed your bees economically and accurately.

Smart Digital Support with BeeInTouch

Inside BeeInTouch, every feeding can be documented directly in the Stock Card App. You can easily see which colonies have been fed and use the bee feeding calculator to plan your next actions. This allows for better seasonal planning, more efficient sugar purchases, and optimal nutrition for your apiary.
