Bee Pests in the UK – Identification, Prevention and Control
Last updated: 1 May 2026
When beekeepers talk about pests, we usually mean animals that live in or around the hive and damage comb, stores or bees themselves. They are different from diseases, which are caused by bacteria, viruses or other pathogens, but the impact on colony health can be just as serious if they are ignored.
This page gives a practical overview of the main hive pests that UK beekeepers are likely to encounter, as well as emerging threats such as small hive beetle and Asian hornet. Use it alongside the guides on bee diseases and pests, other colony conditions, varroa management and good hive hygiene to build a joined-up approach to bee health.
What Counts as a Hive Pest?
A hive pest is any animal that lives in or around the hive and causes damage, stress or loss. Some are tiny and live inside comb; others are larger visitors that raid stores, damage equipment or kill bees. A few are common nuisance pests, while others are serious exotic threats that need official reporting.
Wax moth larvae tunnel through comb and stored frames. Mice can nest in hives over winter and contaminate comb. Wasps and hornets may rob honey or attack weak colonies. Ants and small scavengers often exploit spilled syrup or exposed honey. Small hive beetle and Asian hornet are different again because they are high-concern pests that must be treated seriously if suspected.
Strong colonies in suitable locations can tolerate low levels of many pests, especially if the beekeeper spots them early and takes sensible action. This is one reason seasonal inspections matter: pest pressure changes through the year, and seasonal pages like April, August and October provide specific guidance for each season.
Key Hive Pests for UK Beekeepers
The list below focuses on pests that are either present in the UK or under active surveillance. Always check current guidance on BeeBase for official status and notifiable pest information.
Wax Moth
Wax moth larvae tunnel through comb, leaving silvery tracks, webbing and pellets of frass. They are most troublesome in weak colonies and in comb stored badly between seasons. Good comb storage, strong colonies and good hive hygiene are the best defences.
Wax moth damage is often worst where colonies are weak, comb is old, or equipment has been stored badly. If the colony also looks stressed, under-strength or generally not right, compare what you are seeing with the other colony conditions page as well as this pests guide.
Mice
Mice are mainly a problem in autumn and winter when they seek warmth and shelter. A single mouse can destroy comb and foul frames with urine and droppings. Mouseguards, tidy hive stands and careful spring checks help prevent damage before it becomes expensive or harmful to the colony.
Wasps and Other Hornets
Wasps and some hornet species will opportunistically rob weak colonies, especially late in the season when natural forage is scarce. Strong colonies can usually defend themselves if entrances are not too wide, but nucs, weak colonies and queenless hives can be overwhelmed quickly.
Ants and Small Scavengers
Ants, slugs and other small scavengers are often more of a nuisance than a direct threat, but they can indicate spilled syrup, poor hive stands or other issues around the apiary. Clean stands, limited vegetation and careful feeding usually solve most ant problems without harsh treatment.
Small Hive Beetle and Other Non-native Threats
Small hive beetle and Tropilaelaps mites are not established in the UK but are treated as serious, notifiable threats. Asian hornet is an invasive predator of honey bees that is subject to ongoing monitoring and control efforts.
Bee Pest Overview – Signs and Prevention
This table summarises some of the common and high-concern hive pests for UK beekeepers. Always check official guidance for detailed control measures.
| Pest | Typical signs | Main risks | Prevention focus | Action if found | Notifiable? |
|---|---|---|---|---|---|
| Wax moth | Silvery tunnels, webbing, damaged comb, pellets of frass in corners or frames. | Destroyed comb, weakened colonies, ruined stored frames. | Strong colonies, good comb storage, removing badly damaged comb. | Remove and destroy badly affected comb, improve storage and colony strength. | No |
| Mice | Nesting material, chewed comb and frames, strong smell, droppings on the floor. | Contamination of comb and stores, destruction of brood frames in winter. | Mouseguards in autumn, tidy apiary, raised stands and regular checks. | Remove mice, clean and assess damage, replace contaminated comb. | No |
| Wasps / other hornets | Persistent attacks at the entrance, fighting bees, damaged or robbed comb. | Loss of stores, destruction of weak colonies, stress on neighbours. | Entrance reduction, avoiding exposed honey, maintaining strong colonies. | Reduce entrances, tidy apiary, follow advice if Asian hornet is suspected. | Asian hornet is reportable; other wasps normally are not. |
| Ants / small scavengers | Trails around stands, small numbers inside roof space or under floors. | Usually minor nuisance rather than direct colony threat, but may indicate other problems. | Clean stands, limited vegetation, avoid syrup spills, good hive positioning. | Tidy and adjust apiary layout, consider physical barriers if needed. | No |
| Small hive beetle | Adult beetles and larvae in comb, slimed honey, fermenting smell. | Serious damage to comb and honey; major risk if established in new areas. | Biosecurity, equipment traceability, following import and movement rules. | Treat as an emergency suspicion and report through official channels immediately. | Yes |
Seasonal Pest Pressure Through the Year
Different pests cause problems at different times of year. Linking pest checks to your Year in the Apiary calendar helps spread the workload and reduces the chance of missing seasonal tasks.
| Season | Higher-risk pests | Checks and tasks |
|---|---|---|
| Spring | Wasps scouting, wax moth in weak colonies | Check for early wasp activity, tidy apiary, and assess overwintered comb for damage. |
| Summer | Wax moth, ants and small scavengers | Monitor stored supers, keep the apiary tidy, and avoid leaving exposed comb or cappings. |
| Late summer / autumn | Wasps, hornets, robbing, mice exploring hives | Reduce entrances on weaker colonies, plan mouseguards, and avoid careless feeding. |
| Winter | Mice, occasional scavengers in empty boxes | Fit mouseguards, check straps, and inspect empty equipment before re-use. |

These basics also support wider work on good hive hygiene, bee diseases and pests and varroa monitoring.
Monitoring Tools and Traps
Beekeepers use a mix of visual checks and simple tools to keep an eye on pests. Open mesh floors and inserts can show debris patterns, varroa drop and signs of wax moth. Wasp traps may sometimes be used in late summer around the apiary, but they should be used carefully to avoid catching large numbers of non-target insects.
Mouseguards are simple metal or plastic guards fitted in autumn. Asian hornet monitoring traps may be used in some areas, but always follow current official advice because poorly managed traps can harm other insects.
What to Do if You Find an Infestation
Serious infestations often go hand in hand with other stresses such as disease, starvation or general colony decline. Reviewing your overall hive management, checking the bee diseases and pests overview and comparing signs with other colony conditions can help reduce the chance of problems recurring.
Myth-busting – Hive Pests
Beekeepers are inventive, and you may hear many suggested remedies for pests. Some are harmless, but others can cause more problems than they solve. A few wax moths in stored comb may not seem urgent, but badly damaged comb is best removed rather than put back into hives. Wasps often target weak colonies, but entrance reduction, tidiness and careful feeding can still make a real difference. Ants are usually a nuisance rather than a disaster, so focus on housekeeping before using harsh treatments.
Summary – Staying Ahead of Hive Pests
Hive pests are part of beekeeping, but they do not have to become a disaster. By keeping colonies strong, storing comb properly, using simple physical defences and staying up to date with official guidance, you can stay ahead of most problems.

Bee Pests FAQ
No. Many problems can be managed if caught early, especially in strong colonies.
Freezing is one option some beekeepers use for stored comb. Always follow current advice and handle frames carefully to avoid damage.
Use the channels recommended on BeeBase or by your national beekeeping association and provide clear photographs if possible.
No. Products not designed for beehives can harm bees and contaminate honey. Always follow approved guidance.
