Feeding Bees in the UK – What to Feed, When to Feed and How to Feed Safely

Last updated: 13 October 2026

When should you feed bees? Feed honey bees when their available stores are insufficient or when a nuc, swarm or developing colony needs appropriate support. Strong syrup is commonly used to build winter stores in late summer and autumn, while fondant is useful for emergency feeding in cold weather. Light syrup may suit particular spring or small-colony needs. Always assess the colony first rather than feeding automatically.

Feeding bees in the UK is not just about putting syrup on a hive whenever you think they might be hungry. Good feeding decisions depend on season, temperature, colony size, brood levels, forage availability and the reason for feeding. A strong colony in a nectar flow may need nothing at all, while a small nuc, a recent swarm or a colony entering winter short of stores may need prompt support.

Choose the feed according to the colony’s needs, accessible stores and weather rather than the calendar alone.

Feeding Overview – Feed to Support the Colony, Not by Habit

The main feeds used by UK beekeepers are fondant, light sugar syrup, strong sugar syrup and sometimes commercial invert syrup. Each has its place. Fondant is generally the safer option in colder weather. Syrup is more useful when bees are active enough to take it down and process it properly.

This page brings together the full picture of bee feeding in one place: what to feed, when to feed, how season and temperature affect the choice, how to use feeders and ekes, how to avoid robbing, and why feeding should always sit alongside good hive management, sensible inspection practice and awareness of disease and pest issues.

When Do Bees Need Feeding?

Bees may need feeding for several different reasons, and it helps to be clear which situation you are dealing with before choosing a feed type. Emergency feeding is needed when a colony is dangerously light or at real risk of starvation. Spring support may be useful when colonies are expanding brood but natural forage is unreliable or delayed by weather.

Nucs, splits and swarms often need support because small colonies may not yet have enough drawn comb, flying bees or stores. In late summer and autumn, feeding is usually about helping colonies build enough winter reserves. Feed may also provide short-term support after disruption, such as queen problems, a shook swarm or severe weather, but it will not solve the underlying cause by itself.

Not every colony should be fed routinely. If a colony is healthy, has adequate stores and is working a flow, unnecessary feeding can interfere with natural foraging behaviour and complicate management decisions.

What to Feed Bees

The most common bee feeds in UK beekeeping are straightforward, but each is suited to a different purpose.

Fondant

Fondant is best for colder weather, winter and very early spring. It is useful as an emergency or top-up feed because it can be placed directly above the cluster, allowing bees to reach it with minimal movement.

Light Syrup

Light syrup is typically used in spring and for nucs, swarms or small colonies that need support. It can help bees draw comb and support brood rearing when conditions are warm enough for them to process it properly.

Strong Syrup

Strong syrup is usually given in late summer or autumn. It is used when the aim is to help bees build winter stores efficiently before colder weather arrives.

Commercial Invert Syrup

Commercial invert syrup is used by some beekeepers as an alternative to home-mixed syrup. It can be convenient for larger apiaries or for beekeepers wanting a ready-made option.

Protein Patties and Bee Health Supplements

Protein patties and bee health supplements are specialist products rather than standard feeds. They may have limited roles in some management systems, but they should not replace proper diagnosis, natural forage or sound colony management.

Sugar Syrup Mixtures – Choosing the Right Strength

UK syrup recipes are sometimes called 1:1 or 2:1, but these labels can be ambiguous because traditional imperial recipes and literal metric weight ratios give different quantities. To match HiveTag, the calculator below shows the litres of water to add per 1 kg of white granulated sugar, rather than describing the presets as 1:1 or 2:1.

Thin / spring: 1 kg sugar with 1.26 L water for lighter feeding where appropriate. Medium: 1 kg sugar with 1 L water for general-purpose feeding. Thick / autumn stores: 1 kg sugar with 0.63 L water for building winter reserves when bees can take down and process syrup. These are traditional UK-style recipe quantities rounded to match HiveTag; they are not literal metric sugar-to-water weight ratios.

Prepare syrup with clean water and plain white granulated sugar. Dissolve the sugar using warm water without scorching it, allow the mixture to cool before feeding, and use clean, bee-safe feeders. Discard syrup that has fermented or become contaminated. Do not use brown sugar, molasses or unknown honey as a substitute.

The important point is not just the ratio but the purpose. Lighter and stronger syrup serve different purposes, although the right choice still depends on colony condition and weather. Giving the wrong feed at the wrong time can lead to poor uptake, extra moisture in the hive or stores not being prepared properly for winter.

When bees can no longer take down and process syrup reliably, accessible fondant may be more suitable if supplementary food is needed.

Feeding Bees by Season

Winter

Winter feeding is mostly about avoiding starvation, not stimulating growth. Full liquid feeding is generally unsuitable once conditions are cold. This is where fondant becomes most useful. Place it above the cluster so bees can access it easily. Use quick external checks and repeatable hefting rather than frequent intrusive inspections. A hive may contain food elsewhere on its combs that a cluster cannot reach during prolonged cold. See also A Year in the Apiary for month-by-month guidance.

Early Spring

Early spring can be one of the riskiest times for starvation because brood rearing is increasing just as stores may be running out. A hive can become dangerously light as brood rearing accelerates, even when pollen is coming in. On colder spells, fondant is usually still the safer choice if supplementary feeding is required. Once conditions become reliably milder, some beekeepers may use lighter syrup to support build-up where genuinely needed. See A Year in the Apiary for seasonal timing.

Late Spring and Summer

Established productive colonies often do not need feeding during a good flow, but nucs, artificial swarms, casts and small splits often do. Here the aim may be to help them draw comb and establish themselves. Feeding must be managed carefully to avoid robbing, especially in poor weather or forage gaps. Keep supplementary feed out of honey supers intended for harvesting and stop feeding appropriately before collecting a honey crop.

Late Summer and Autumn

This is the main store-building period for many UK beekeepers. After honey removal and alongside autumn management, colonies often need strong syrup or commercial invert feed so they can enter winter with enough reserves. Feeding is usually best done in larger, tidy feeds and early enough for bees to process it properly before colder weather arrives. For detailed store-building guidance, see Feeding Bees for Winter UK, or follow A Year in the Apiary for monthly tasks.

Temperature, Weather and Feeding Decisions

Temperature matters because bees do not just consume syrup. They have to take it down, move it, evaporate moisture and store it properly. In cold weather they are less able or less willing to do that, which is why syrup becomes less suitable as autumn deepens and winter begins.

In colder conditions, fondant is usually the safer choice. In warmer, settled conditions, syrup is more practical. Cold snaps in spring can make a colony look active from the outside while still leaving it unable to access or process feed properly.

Feeding decisions should therefore be based on a combination of stores, cluster position, weather, season and purpose, not on a fixed rule used all year round.

Fondant – When and How to Use It

Fondant is one of the most useful feeds in UK beekeeping because it works well as an emergency or top-up feed during colder periods. It contains very little free water compared with syrup, so bees can use it without the same need to process and evaporate moisture.

Place fondant above the cluster, ideally over the feed hole or directly above the brood nest. Cut a slit in the packaging or remove a small section so bees can access it. Use an eke, empty super or other spacer if extra headroom is needed under the roof.

Fondant is especially useful when colonies feel light but the weather is too cold for syrup. It is also valuable in late winter and early spring when brood is increasing but flying weather remains unreliable. For more detail about timing and placement, see When to Feed Fondant to Bees.

Different Feeders and When to Use Them

The right feeder depends on the feed type, colony size and time of year. Internal feeders are usually preferred because they reduce exposure and lower robbing risk compared with open external feeding.

The most important features are that the feeder is clean, secure, bee-accessible, suitable for the colony and not prone to dripping or leaking. Syrup spills are one of the quickest ways to start robbing.

Where to Put Feed and How to Use an Eke

An eke is simply a shallow spacer that creates extra room above the brood box or crownboard. It is especially useful when feeding fondant or when a feeder needs more headroom than the roof allows.

Fondant is often best placed above the cluster, over the crownboard feed hole or directly over the brood nest. An eke can give enough depth for the fondant block while keeping the setup neat and weatherproof. Some beekeepers use an empty super instead of an eke where suitable.

Choose an eke or spacer that allows the roof to fit properly without leaving gaps. For syrup feeders, placement should always be secure and internal where possible. A badly fitted feeder or one that allows syrup to leak into the hive or outside it can cause unnecessary stress and robbing pressure.

How to Avoid Robbing When Feeding Bees

Robbing is one of the biggest risks associated with feeding, particularly in late summer, autumn or during forage shortages. Bees from stronger colonies will exploit exposed syrup, weak colonies or leaky feeding setups very quickly.

Feed in the evening where possible, avoid all spills, keep entrances at a defendable size and use internal feeders rather than open feeding. Never leave open bowls of syrup or exposed feed in the apiary. Repeated small messy feeds can keep syrup scent levels high around the apiary and make robbing more likely.

Signs of robbing can include frantic flight, fighting at the entrance, bees darting and probing around cracks, wax debris and general aggression. If robbing starts, tidy up immediately and reduce disturbance around the apiary.

Feeding Nucs, Swarms and Weak Colonies

Smaller colonies often need more targeted feeding than established production colonies. A nuc or swarm may not yet have enough bees, drawn comb or stored food to become self-sufficient quickly, especially if weather turns poor.

Nucs often benefit from careful light feeding when establishing. Swarms may need feeding to draw comb and settle, depending on conditions and your management aim. Weak colonies may need support, but feeding alone will not fix deeper issues such as failing queens, heavy mite loads or disease. Assess colony health before considering uniting colonies, and never unite a colony suspected of infectious disease with a healthy one. Follow veterinary medicine and treatment label instructions, and keep feed away from honey supers intended for harvest.

These colonies are also at higher risk of robbing, so the feeding method needs to be tidy, secure and proportionate.

Bee Health Fluids, Supplements and Realistic Expectations

Many products are marketed as bee health tonics, liquid supplements or support feeds. These may appeal to beekeepers looking for an extra way to help colonies, but they should be treated with caution and perspective.

Supplements are not a substitute for adequate stores, good forage, sensible apiary siting, strong queens, proper varroa management or awareness of disease and pest problems.

If a colony is struggling, the first question should be why. Feed may support recovery, but it will not solve the wrong problem. Use the Bee Health Checker or your own inspection notes to separate simple lack of stores from a more serious issue.

Common Feeding Mistakes

Common mistakes include using syrup too late into cold weather instead of switching to fondant, feeding without first judging whether the colony actually needs it, using the wrong syrup strength for the season and spilling syrup in a way that triggers robbing.

Other mistakes include putting feed too far from the cluster in winter, assuming a colony is safe simply because the hive feels heavy, and trying to fix deeper queen, disease or varroa problems with feed alone.

Quick Feeding Checklist

Before feeding, ask yourself why you are feeding this colony and whether the feed matches the season, temperature and purpose. Check whether the colony is genuinely short of stores, whether the feeder is secure and internal, and whether the setup could trigger robbing.

Also consider whether the feed is positioned where the bees can actually reach it. In winter and cold spells, food that is technically present in the hive may still be useless if the cluster cannot access it. Finally, make sure you have not mistaken queen problems, varroa pressure or disease for simple hunger.
