Wasp Nest Removal in Oakland, California

Not sure what you have? Drop in a photo

Drop a photo in and we will tell you what you are looking at. Nothing is sent anywhere on the strength of that: the identification comes back to you, and then it is your call. If it is honey bees you can pass it to a local beekeeper, who will normally collect a swarm free. If it is wasps or hornets you can pass it to a local removal pro who works without putting nearby bees at risk. Most people cannot tell the two apart from a distance, and that difference decides who turns up and what it costs.

Before you reach for a spray can

Wasp and hornet sprays do not distinguish between a wasp nest and a honey bee colony, and neither do most people looking up at one. That is why the EPA requires a bee hazard warning on the labels of products toxic to pollinators, and why its 2017 policy on acute risk to bees exists at all.

• Sprays do not tell a wasp nest from a honey bee colony, and a colony killed by mistake is killed for nothing.
• If it is inside a wall, the comb and honey stay behind after the bees are dead, and the wall has to be opened anyway.

On that second point, extension services are consistent on this: the abandoned comb and stored honey are left behind, and in warm weather the honey can melt, ooze through the wall or ceiling, and attract ants, wax moths, hive beetles, rodents and roaches. Ohio State University Extension covers this in Honey Bees in House Walls, as does University of Georgia Extension. Both note that the residual comb and its odour go on attracting new swarms to the same cavity, so the wall has to be opened and cleared either way.

Checking a photo first rules that out in a minute. If it is wasps, you have also learned where the nest is, which is what decides whether this is a ladder job or a wall-opening job.

When do wasps go away around Oakland?

Yellowjacket and hornet colonies live a single year. The workers die off with the cold and the nest is not reused. Alameda County is unusual: winters here are not reliably cold enough to end a colony, and in 9 of the last 10 years it didn’t freeze at all, so a nest can stay active far later than people expect. Some activity carries on into November here.

What people find around Oakland

No single type dominates around Alameda County. Paper wasps and yellowjackets are all common here, so a photo is the quickest way to know which you have. German yellowjackets are recorded here too.

Honey bees are a different season, and a different call

Honey bee swarms around Oakland are reported most in May, months earlier than wasp and hornet nests reach full size. A swarm is normally collected free by a local beekeeper, while a colony already established inside a structure is paid work the beekeeper quotes directly. Either way it is worth checking a photo first.

Common questions

When do wasps go away around Oakland?

Yellowjacket and hornet colonies live a single year, but Alameda County is not reliably cold enough to end one, so a nest here can stay active far later in the year than people expect.

Is it wasps or honey bees?

Send a photo through the check on this page and we will tell you which you are looking at. It matters because a honey bee swarm is normally collected free by a local beekeeper, while a wasp or hornet nest is paid removal work.

How much does wasp nest removal cost in Oakland?

It depends almost entirely on where the nest is. An exposed comb within reach of a ladder is the cheapest case; a nest inside a wall or underground can mean opening a cavity, which is a different job. Anyone quoting before they know which one you have is guessing.

Will wasp spray hurt honey bees?

Yes. Wasp and hornet sprays do not distinguish between a wasp nest and a honey bee colony, which is why the EPA requires bee hazard warnings on the labels of products toxic to pollinators. If a colony inside a wall is killed, the comb and honey are also left behind and can melt, seep through the wall and attract ants, wax moths, beetles and rodents, so the wall has to be opened either way.

Do wasps come back to the same nest next year?

No. Yellowjacket, hornet and paper wasp nests are annual. The colony dies with the cold and next year's queens start somewhere new, so an old nest left in place is not what brings them back.
