About this guide
Honey bee removal is primarily a task for local beekeepers, not pest controllers. This guide explains when to contact the BBKA swarm register, when a specialist beekeeper is needed for structural colony removal, and in what limited circumstances pest control involvement may be appropriate. It also covers the legal framework and what happens when a honey bee colony becomes established in a building cavity.
Honey Bees Are Not a Pest Species
The honey bee (Apis mellifera) is the most significant managed pollinator of agricultural crops in the UK, with a contribution to crop pollination valued at over £650 million per year (Defra / BBKA / POST). It is not classified as a pest species, and BPCA guidance is unambiguous: honey bee colonies should be relocated by a trained beekeeper rather than destroyed wherever this is practically possible.
Honey bee colonies contain 20,000–80,000 workers at peak summer strength. A settled swarm — which has no nest to defend — is not aggressive and typically relocates within 1–2 days as scout bees locate a suitable cavity nest site.

When a honey bee swarm appears on a fence, tree branch, or building exterior, the correct response is to contact the BBKA swarm collection register — not a pest controller. Registered BBKA collectors attend swarms free of charge in most cases. The swarm register is searchable by postcode at bbka.org.uk.
Understanding Honey Bee Swarms
Why Swarms Occur
Swarming is the honey bee colony's natural reproductive mechanism. When a colony becomes overcrowded — typically in late spring or early summer — the old queen departs with approximately half the worker bees to found a new colony elsewhere. The swarm settles temporarily whilst scout bees evaluate potential cavity nest sites. This settling phase lasts from a few hours to 1–2 days. Swarm season in the UK typically runs from May to July, with peak activity in May and June.
Swarms Are Not Aggressive
A settled honey bee swarm cluster has no nest to defend. Workers are gorged on honey taken before departing the original hive, which reduces their propensity to sting. Unprovoked stinging from a settled swarm is extremely rare. A swarm cluster on a fence or tree branch should be given space but is not a danger to bystanders who do not disturb it. The exception to this general rule is any individual with a documented bee venom allergy — approximately 3% of the UK population has clinical bee venom allergy, for whom the proximity of any large bee colony carries anaphylaxis risk.
What to Do With a Swarm
Contact the BBKA swarm register (bbka.org.uk) and provide your postcode — the system connects you with local registered swarm collectors. If a collector cannot attend promptly and the swarm is in a low-risk location, leaving it in place is often the best option: it will most likely relocate within 24–48 hours. Do not spray a swarm with water or insecticide — this causes the colony to become defensive and increases the risk of stings.

Sheffield, Leeds, Barnsley, Rotherham and surrounding areas are covered by active local beekeeping associations.
Established Colonies in Buildings
How Colonies Get Established
When a swarm is not intercepted and a suitable cavity is available — chimney stack, wall void, roof soffit, roof void — the swarm occupies the cavity and establishes a permanent colony. Unlike bumble bees, honey bee colonies are perennial: they do not die off at the end of summer but persist year-round, building increasingly large honeycomb structures within the cavity over successive seasons.
Specialist Beekeeper Removal
An established colony in a building structure requires a specialist beekeeper with access skills, appropriate protective equipment, and the ability to remove all colony material — bees and honeycomb — from the cavity. This is not a standard swarm collection and not all BBKA-registered collectors offer structural removal. Contact a company specialising in honey bee removal from buildings.
Why Comb Removal Is Essential
If a honey bee colony is killed without removing the honeycomb — whether by insecticide or another method — the unmanaged comb creates serious secondary problems. In warm weather, the wax melts and honey ferments, causing structural staining, seeping through ceilings and walls, and attracting wax moth, rodents, and other secondary pests. Any insecticidal treatment of a colony in a building cavity should always be followed by professional comb removal — this is clearly stated in BPCA guidance.
Legal Framework
Wildlife and Countryside Act 1981
Apis mellifera is not listed on Schedule 5 of the Wildlife and Countryside Act 1981 and has no specific legal protection from killing or disturbance under that Act. However, this does not mean honey bees should be destroyed — the ecological and agricultural importance of the species means that colony destruction should be treated as a last resort only.
Bees Act 1980
The Bees Act 1980 empowers APHA-appointed bee inspectors to enter premises to inspect for notifiable bee diseases — American foulbrood (caused by Paenibacillus larvae) and European foulbrood (caused by Melissococcus plutonius). A confirmed positive diagnosis requires notification to APHA. The Act is a bee health measure; it does not govern pest management decisions about honey bee swarms or colonies in buildings.
When Is Pest Control Involvement Appropriate?
BPCA guidance identifies insecticide treatment of a honey bee colony as appropriate only as a last resort: when a beekeeper solution is genuinely not available, when the colony presents an immediate risk to human health (particularly where a documented bee venom allergy is present), and when no other option exists. In practice, beekeeper options exist in almost all UK locations via the BBKA register. Pest control companies should refer honey bee swarms and structural colonies to the BBKA register as a first response in all cases.
Frequently Asked Questions
Should I call a pest controller or a beekeeper for a honey bee swarm?
A beekeeper — not a pest controller — is the correct first call for a honey bee swarm. The BBKA maintains a postcode-searchable swarm collection register at bbka.org.uk. Registered collectors will attend free of charge in most cases. BPCA guidance is clear that honey bee colonies should not be destroyed when a beekeeper option exists.
Are honey bee swarms dangerous?
A settled honey bee swarm is typically not aggressive. Swarms have no nest to defend, and workers gorged on honey before leaving the hive are less inclined to sting. Unprovoked stinging from a settled swarm cluster is rare. The exception is an individual with a known bee venom allergy — for whom the proximity of any large bee colony is a serious risk.
How long will a honey bee swarm stay?
A settled swarm typically remains in place for a few hours to 1–2 days whilst scout bees locate a suitable cavity nest site. Once a site is agreed, the swarm moves on. If a swarm has settled in a low-risk location away from people and the BBKA register cannot immediately connect you with a collector, leaving the swarm alone is often the most practical option.
Can honey bees in a chimney or wall be removed?
Yes, but this requires a specialist beekeeper with access skills and appropriate equipment — not all beekeepers offer structural colony removal. The colony must be physically removed along with all honeycomb. If the comb is left after the bees are removed (or killed), it will melt and ferment in warm weather, causing structural damage, attracting secondary pests, and potentially seeping through ceilings. Contact a specialist beekeeper with structural removal experience.
When is it appropriate to call a pest controller for bees?
Pest control involvement with honey bees is appropriate only as a last resort — when a beekeeper is not available, the colony poses a genuine and immediate risk to health (particularly where a documented bee venom allergy is present), and no other option exists. Any insecticide treatment of a honey bee colony should be followed by professional comb removal to prevent secondary problems.
What is the Bees Act 1980?
The Bees Act 1980 empowers inspectors appointed by the Animal and Plant Health Agency (APHA) to enter premises to inspect for notifiable bee diseases — American foulbrood (Paenibacillus larvae) and European foulbrood (Melissococcus plutonius). A confirmed positive diagnosis requires notification to APHA. The Act is a disease management measure, not a pest control or animal welfare law.
Are bumble bees protected in the UK?
Bumble bees (Bombus spp.) are not listed on Schedule 5 of the Wildlife and Countryside Act 1981 as a whole genus, though specific species with rare or threatened status may have legal protection. The BPCA advises strongly against routine control of bumble bee nests — colonies are annual (they do not overwinter) and will naturally decline and abandon the nest by late summer. Unless the nest presents a direct risk, leaving it alone is the recommended approach.
