Bee Removal and Live Relocation in California: How It Works

Bee removal in California depends on what you have. A swarm on a branch is a colony in transit, and a beekeeper can often capture it alive. An established colony inside a wall needs the comb cut out, whether the bees are relocated or treated. The Los Angeles County Agricultural Commissioner estimates that 80 percent of feral bees are Africanized. Live relocation is the goal when behavior and access allow it, not a guarantee.

Is it a honey bee swarm or an established hive?

A swarm is temporary; a hive has moved in. UC IPM explains that the old queen leaves with about half the workers and clusters nearby while scouts hunt for a cavity. Los Angeles County says a swarm left alone usually leaves within two to three days. Most spring swarms of European honey bees are docile because they are not protecting brood.

An established colony starts when scouts find a dark cavity of around nine gallons: a wall void, a chimney or a water meter box. The bees build comb quickly; UC IPM notes a well-established colony may hold up to 100 pounds of honey. A steady line of bees using the same gap, or a low hum behind drywall, means comb, not a swarm.

What is live bee relocation, and how does it work?

Live relocation means the bees are captured alive and moved to a managed apiary, and the comb leaves with them. UC IPM describes two different jobs.

Swarm capture. The beekeeper brushes or shakes the cluster into a box with an entrance so flying bees can rejoin. The box sits in the shade until nightfall, then it is sealed and removed after dark.
Cut-out. Inside a wall or roof, the beekeeper first finds the comb by tapping and listening for the hum. Then a large hole is opened, the bees and combs are lifted out, the cavity is filled with insulation, and every entrance is sealed and refinished.

Why is live relocation preferred, and when is it not possible?

Relocation is preferred because it saves a pollinator colony, keeps pesticide out of your wall, and the comb has to come out either way. Four situations rule it out.

The colony is defensive. The county's apiary guidance says colonies deemed aggressive should be destroyed or re-queened immediately for public safety. UC IPM adds that pest control companies generally kill the bees before removing them. In Africanized areas, which include every Southern California county, it says a structural pest control company may be your only option.
There is no safe access. Los Angeles County notes that a pest control company may be needed to remove bees with a pesticide when they are not easily accessible.
The hazard is immediate. A school gate, an apartment stairwell or a severely allergic household member rules out a long cut-out with thousands of airborne bees. The county warns that bees may sting people 100 feet or more from the hive.
Someone already sprayed. Comb hit with store-bought insecticide cannot go to an apiary. UC IPM states that honey, wax and dead bees contaminated by pesticide must be handled as hazardous waste.

UC IPM states that a killed colony left in place lets honey ferment and leak through walls and ceilings. Our guide on when a wasp or bee nest becomes a safety risk covers what to do while you wait.

Are Africanized bees really a factor in Southern California?

Yes, for decades. UC Riverside records the first California detection in October 1994, and by 1999 they had been found in most areas of Los Angeles and San Bernardino counties. Only measurements under a microscope or DNA analysis can tell them apart from European honey bees. Behavior differs: colonies are easily disturbed, many more bees join the defense, and they continue the attack over a long distance.

For removal, every colony in a wall or meter box is treated as potentially defensive until a professional has watched it work. UC IPM warns that Africanized swarms, or any swarm that has run out of food, can be touchy even as clusters.

Should you call a beekeeper or a pest control company?

Call a beekeeper for a swarm you can reach, and a licensed pest control company or live-removal specialist for a colony inside a structure. The Los Angeles County Agricultural Commissioner does not provide bee removal and does not respond to wasp complaints. It does publish referral lists of live-removal beekeepers and licensed pest control companies.

Swarm on a branch, fence or eave: a beekeeper. The county calls its live-removal list a convenience, not an endorsement, and not free.
Colony inside a wall, roof, chimney or meter box: a company that does structural cut-outs. UC IPM advises agreeing in advance whether the cavity will be opened, cleaned out, filled, resealed and refinished.
Wasps, yellowjackets or hornets: a licensed pest control company. See our guide to wasp removal in Los Angeles.
Bees on a neighbor's property: the county Bee Info Line at (800) 233-9279 or its online complaint form. If the colony is determined to be a public nuisance, County Public Health Ordinance 11.02.190 requires whoever controls the property to abate it.

The county's apiary guidance states that live bee removal does not require a State Pest Control Business License, while any use of pesticides does. Verify a company through the Structural Pest Control Board license search before hiring; canceled licenses do not appear in the results.

What does PesPro do for bees, wasps and yellowjackets?

PesPro removes wasp and hornet nests and yellowjacket colonies, applies preventive treatments to discourage rebuilding, and offers live bee relocation when feasible. Our wasp and bee control service covers homes, apartment buildings and businesses across Los Angeles County and San Bernardino County, in English and Spanish.

Honey bees. Relocation is the plan when the colony's behavior and location allow it. Otherwise the colony is treated. Either way, ask before work starts whether the comb comes out and who closes the wall.
Wasps, hornets and yellowjackets. These nests are not relocated. Technicians remove the nest and treat the site to discourage rebuilding.

Same-day service is available for an extra fee and depends on the route. The written quote is free. Stinging insects fall under the second tier of our 30-day guarantee: a return visit within 30 days costs 30 percent of the original price. PesPro holds California Structural Pest Control Board License #PR-6378 and is QualityPro certified. For an active stinging emergency, the 24/7 line is (323) 472-5329.

Frequently asked questions

How long will a bee swarm stay on my tree?

Usually two to three days if nobody disturbs it, according to Los Angeles County, and sometimes only a few hours. Swarms are most common in April, May and June. UC IPM says a cluster that keeps shrinking without flying off is probably moving into a nearby cavity, and that is the moment to call.

Is live bee removal free?

No. Los Angeles County states that its referral list is not a free live honeybee removal service. UC IPM notes that beekeepers may collect a swarm at no charge, but removing an established colony is seldom worth their time without payment. PesPro's written quote is free; the price depends on the pest and the property.

What happens to relocated bees?

They go to a managed apiary. Los Angeles County says some beekeepers add swarm bees to their existing colonies. The county wants hives re-queened with docile European queens of known genetics, to prevent cross-breeding with feral bees. Its apiary guidance adds that re-queening with temperate queens helps prevent aggressiveness.

Can I just seal the bees inside the wall?

Not once comb is built. UC IPM describes locking bees in with screen or steel wool only when they have just arrived. Even then, trapped bees search the walls for another exit, often into living spaces. The comb has to come out, so the order is removal first, then sealing every gap a pencil fits through.
