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

Last updated: 1 May 2026

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.

Feeding at a Glance – The Key Principles

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 you choose a feed type.

• Emergency feeding: when a colony is dangerously light or at real risk of starvation.
• Spring support: when colonies are expanding brood but natural forage is unreliable or delayed by weather.
• Nucs, splits and swarms: when small colonies do not yet have enough drawn comb, flying bees or stores.
• Autumn store building: when colonies need help building enough reserves for winter.
• Short-term support after disruption: for example after queen issues, a shook swarm or severe weather, though feed alone will not solve the underlying cause.

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

• Best for colder weather, winter and very early spring.
• Useful as an emergency or top-up feed.
• Can be placed directly above the cluster so bees can reach it with minimal movement.

Light Syrup

• Typically used in spring and for nucs, swarms or small colonies needing support.
• Helps bees draw comb and supports brood rearing when conditions allow.

Strong Syrup

• Usually given in late summer or autumn.
• Used when the aim is to help bees build winter stores efficiently.

Commercial Invert Syrup

• Used by some beekeepers as an alternative to home-mixed syrup.
• Can be convenient for larger apiaries or those wanting a ready-made option.

Protein Patties and Bee Health Supplements

• These 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 – When to Use 1:1 and 2:1

Beekeepers often refer to syrup strength in simple terms such as 1:1 and 2:1. These ratios are shorthand for lighter and stronger syrup mixes, and they are used for different reasons.

• 1:1 syrup is generally used in spring or for smaller colonies that need support. It is associated with brood expansion, comb drawing and lighter feeding.
• 2:1 syrup is generally used in late summer and autumn when the goal is to help colonies store food for winter more efficiently.

The important point is not just the ratio but the purpose. Lighter syrup and stronger syrup are not interchangeable. 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.

If the weather is already turning cold, it is often better to stop thinking in terms of syrup altogether and switch to fondant instead.

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 checks and hefting rather than frequent intrusive inspections. 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. On colder spells, fondant is usually still the safer choice. 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.

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. See A Year in the Apiary for month-specific 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.
• Always think about local weather, exposure, colony size and what the bees can realistically manage.

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.
• Check consumption during colder months without disturbing the colony more than necessary.

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.

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.

• Rapid feeders: commonly used for syrup feeding, especially for autumn feeding or larger volumes.
• Contact feeders: useful for smaller feeds and straightforward setups.
• Frame feeders: placed inside the brood box and useful in some management systems, though they take up frame space.
• Fondant over the crownboard hole: simple and effective in colder weather.
• Bucket or tub feeding systems: used by some beekeepers where appropriate, provided they are secure and do not leak.

The most important features are that the feeder is safe, bee-accessible, tidy 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.
• The key principle is access: in colder weather the feed should be as close and reachable as possible.

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, drips and exposed syrup.
• Keep entrances at a defendable size, especially on weaker colonies and nucs.
• Use internal feeders rather than open feeding.
• Avoid repeated small messy feeds that keep apiary scent levels high.

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 management aim.
• Weak colonies may need support, but feeding alone will not fix deeper issues such as failing queens, heavy mite loads or disease.

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.

They are not a substitute for:

• adequate stores
• good forage and sensible apiary siting
• strong queens
• proper varroa management
• 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

• 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 purpose.
• Spilling syrup and triggering robbing.
• Putting feed too far from the cluster in winter.
• Assuming a colony is safe because the hive feels heavy, even though the bees may be unable to reach stores in a cold spell.
• Trying to fix deeper colony problems with feed alone.

Quick Feeding Checklist

• ✔ Why am I feeding this colony?
• ✔ Is this the right feed for the season and temperature?
• ✔ Is the colony genuinely short of stores or just not using them well?
• ✔ Is the feeder secure, internal and unlikely to leak?
• ✔ Could this trigger robbing?
• ✔ Is the feed positioned where bees can actually reach it?
• ✔ Have I ruled out queen, varroa or disease problems?
