About this guide
Bee nest removal is not primarily a pest control task. Honey bee swarms and nests should be referred to local beekeepers via the BBKA register. Bumble bee nests should be left alone until the colony naturally ends. Solitary bees need no intervention. This guide explains what to do with each type of bee nest, when specialist beekeeper help is needed, and what happens when a honey bee colony becomes established in a building structure.
Identifying the Bee Species Before Acting
The correct response to a bee nest depends entirely on which bee species is involved. Pest controllers, householders, and building managers regularly confuse honey bees, bumble bees, and solitary bees — and the management pathway for each is completely different.
Honey bee colonies contain 20,000–80,000 workers at summer peak and are perennial — they persist year-round, unlike bumble bee colonies which are annual and naturally die off by late summer.

Honey Bee Nests and Swarms
Honey bees (Apis mellifera) form large perennial colonies that persist year-round. When a colony becomes overcrowded in spring or summer, it swarms — the queen leaves with half the workers and the swarm settles temporarily whilst seeking a new cavity nest site. Once established in a cavity (chimney, wall void, roof soffit, tree cavity), the colony is permanent. Workers are 10–15 mm, golden-brown to amber. Management: refer to the BBKA swarm register (bbka.org.uk). Do not call pest control as a first response.
Bumble Bee Nests
Bumble bees (Bombus spp.) form annual colonies. A mated queen overwinters and starts a new nest in spring in a suitable cavity — compost heap, bird box, roof soffit, wall cavity. The colony builds through spring and summer, peaks in midsummer, and then naturally declines. By late summer (typically August–September), the colony has died and the nest is abandoned. The nest has no further pest significance after abandonment. Management: leave alone until natural die-off. Seal the entrance in late autumn to prevent reuse the following year.
Solitary Bees
Solitary bees (mining bees, mason bees, leafcutter bees) do not form colonies. Each female constructs individual nest cells — in soil, mortar joints, hollow stems, or purpose-made bee houses. They are non-aggressive and have no colony to defend. Management: no action required. They are beneficial pollinators and should not be disturbed.
Tree bumble bee (Bombus hypnorum): This non-native species commonly nests in bird boxes and roof soffits. Foraging workers hovering near the nest entrance are frequently mistaken for wasps. Tree bumble bees are not aggressive. The colony is annual — leave alone and it will naturally end by late summer. Do not block the entrance while the colony is active.
Honey Bee Swarm Removal
The BBKA Swarm Register
The British Beekeepers Association maintains a postcode-searchable swarm collection register at bbka.org.uk. Registered volunteer swarm collectors will attend free of charge in most cases. This is the correct first response to a honey bee swarm settled on a tree, fence, or building exterior. Swarms are temporary — they typically relocate within 24–48 hours as scouts locate a suitable cavity — so leaving a swarm in a low-risk, accessible location and waiting for a BBKA collector is often the most practical option.
Swarm Behaviour
A settled honey bee swarm cluster is not aggressive. Workers are gorged on honey taken before leaving the hive and have no nest to defend. Unprovoked stinging from a settled swarm is extremely rare. Leave the swarm undisturbed and maintain a safe distance — particularly important if any household member has a documented bee venom allergy (approximately 3% of the UK population has clinical sensitivity to bee venom).
Honey Bee Colony Removal From Buildings
Structural Colony Removal
A honey bee colony established in a chimney stack, wall cavity, or roof void requires a specialist beekeeper with structural access skills and appropriate protective equipment. Not all BBKA-registered swarm collectors offer structural colony removal — contact the BBKA for a specialist referral. The colony and all honeycomb must be removed to prevent secondary problems.
Why Comb Removal Is Essential
If a honey bee colony is killed or dies without the honeycomb being physically removed, the wax melts and honey ferments in warm conditions — causing structural staining, persistent odour, and attracting secondary pests including wax moth, rodents, and in warmer climates, small hive beetle. Any insecticide treatment of a structural colony must always be followed by professional comb removal. This is clearly stated in BPCA guidance.
When Pest Control Is Appropriate for Bees
BPCA guidance identifies insecticide treatment of a honey bee colony as a last resort — appropriate only when a beekeeper option is genuinely unavailable, the colony presents an immediate risk to human health (particularly where a documented bee venom allergy exists), and no other option is available. The BBKA register provides coverage across all UK areas, meaning a beekeeper option exists in the vast majority of situations.
Legal Framework
Honey bees are not listed on Schedule 5 of the Wildlife and Countryside Act 1981 and have no specific legal protection from killing or disturbance under UK law. However, the ecological and agricultural importance of the species — with an estimated contribution of over £650 million per year to UK crop pollination — means that destruction should be a genuine last resort. The Bees Act 1980 empowers APHA-appointed inspectors to enter premises for notifiable bee disease inspections (American foulbrood; European foulbrood) but does not govern pest management decisions about bee nests or swarms.
Frequently Asked Questions
Should I call pest control or a beekeeper for a bee nest?
This depends on the species. Honey bee swarms and nests should be referred to a local beekeeper via the BBKA swarm register (bbka.org.uk) — beekeeper referral is the correct first response in all cases. Bumble bee nests should be left alone if possible — colonies are annual and die naturally by late summer. Solitary bee nests need no action. Pest control is only appropriate as a last resort for honey bee nests where a beekeeper option is genuinely unavailable.
Can I remove a bee nest myself?
Attempting to remove a honey bee colony without beekeeping training and a bee suit is not safe and is unlikely to be effective. Bumble bee and solitary bee nests should not be removed at all in most cases. If a honey bee colony has established in a structural cavity (chimney, wall void), contact a specialist beekeeper with structural removal skills — this is not a job for a pest controller or a general handyperson.
How long does it take for a bumble bee nest to die naturally?
Bumble bee colonies in the UK are annual. They build from spring, peak in midsummer, and naturally decline by late summer — typically August to September. The colony then dies, the nest is abandoned, and the mated queens overwinter to start new colonies the following spring. Leaving a bumble bee nest alone until this natural die-off is the recommended approach in almost all cases.
What happens if I block the entrance to a bee nest?
Blocking the entrance to an active honey bee colony forces bees to find alternative exits — which may be into internal spaces. For a bumble bee nest, blocking the entrance during active foraging can cause bees to become disoriented and distressed. Nest entrances should only be sealed after the colony has naturally died off and all activity has ceased — typically late autumn.
Are solitary bees in my garden harmful?
No. Solitary bees (mining bees, mason bees, leafcutter bees) are non-aggressive, non-colonial, and do not have a colony to defend. A single individual has an extremely low sting risk. Their presence in garden soil or mortar joints indicates suitable nesting habitat and has no pest significance. They are beneficial pollinators and should be left undisturbed.
Why do honey bee colonies in chimneys cause damage?
An established honey bee colony fills the cavity with wax honeycomb over successive seasons. If the colony dies — from disease, poisoning, or winter loss — without the comb being removed, the wax melts in warm weather and honey ferments. This causes structural staining of ceilings and walls, attracting secondary pests (wax moth, rodents, small beetles) and creating persistent odour. Professional comb removal after colony death or removal is essential to prevent these secondary problems.
Is a bee nest in my roof dangerous?
A honey bee colony in a roof void does not immediately pose a danger to occupants unless the colony is disturbed or a household member has a bee venom allergy. Honey bees are not aggressive unless threatened. The long-term issue is structural — the colony will grow over years and the honeycomb will eventually require professional removal. Contact the BBKA for specialist structural removal referral. For individuals with bee venom allergy, proximity to any bee colony warrants earlier action.
