Chimneys are less common in Las Vegas homes than in cooler climates — most homes here have a gas fireplace insert or no fireplace at all. But decorative chimneys, chase structures around water heater and furnace flues, and standard wood-burning fireplaces exist throughout the valley, and all of them can attract bee colonies. A chimney bee infestation is a different kind of problem than a wall or attic colony, with some specific complications worth knowing before you call.
How Bees Get Into a Chimney
The most common entry points:
Uncapped or damaged chimney crowns. A masonry chimney without a proper cap — or with a cap that has corroded, shifted, or been damaged — is an open invitation. The flue is a dark, sheltered cavity that’s excellent bee habitat from a structural standpoint.
Gaps in the chimney chase. Many Las Vegas homes have a framed wood chase structure (essentially a box around the flue pipe) rather than a full masonry chimney. These chases often have gaps at the top, at transitions between the chase and the roofline, and around the flue pipe penetration. Bees entering the chase void — not the flue itself — is actually more common than bees inside the flue.
Flashing separation. Where the chimney base meets the roof, metal flashing seals the gap. When flashing pulls away from masonry, it creates accessible gaps at the roofline level.
Spark arrestors with missing or corroded mesh. Spark arrestors — the mesh caps required on fireplace chimneys — keep embers in but also keep bees out when intact. Corroded or missing arrestor mesh is a direct entry point into the flue.
Flue vs. Chase: Why the Distinction Matters
Bees inside the flue (the actual smoke passage) build comb attached to the flue walls or smoke shelf. This is the less common scenario because the flue is narrower and less hospitable than a chase void. However, when it happens, it’s a more difficult extraction — the flue dimensions are constrained and access is typically from above (through the chimney crown) and from below (through the firebox).
Bees inside the chase void (the space around the flue pipe inside a framed chase structure) is more common. The chase can be several feet wide, providing generous nesting space. Colony size potential in a chase void is comparable to an attic — large and potentially expanding.
Why You Can’t Just Light a Fire
The instinct of many homeowners is to use the fireplace to drive the bees out. This does not work and creates additional problems:
- Smoke from below does not clear bees from above. Professional bee smokers use specific technique and materials to create cool, white smoke that triggers a bee response. A roaring fire produces dense, hot smoke that does not replicate this effect and can push bees deeper into the structure or force them into the living space through the damper.
- Heat can melt comb. Wax melts at relatively low temperatures. A fire in the firebox can liquefy the honey stored in comb above, causing it to run down the flue walls — and in extreme cases, creating a flammable honey-wax mixture in the flue.
- It doesn’t solve the problem. Even if bees are displaced by heat, the comb remains in place and the entry point is still open. The colony will return to the same location or a new swarm will colonize it within weeks.
How Chimney Bee Removal Works
Chase void colonies: Access is typically from the roof — the chase top is opened (or the entry point is widened as needed) to expose the colony from above. Full comb extraction, cavity treatment, and sealing of the chase top with appropriate hardware is the standard approach.
Flue colonies: Access is from both ends — through the crown from the roof and through the firebox from inside. The smoke shelf and accessible areas of the lower flue are worked from below; the upper flue and crown area from above. This is a two-person job in most cases.
Entry point sealing: After extraction, a proper chimney cap or spark arrestor is installed to prevent re-entry. For chase structures, the top is sealed with flashing and appropriate mesh. This is the permanent fix — without capping the chimney properly, re-colonization is likely.
Important: If you use the fireplace, have the flue inspected after any bee removal in or near the chimney. Residual comb or honey in the flue is a fire hazard.
What Chimney Bee Removal Costs
Chimney and chase removals run $400 to $700+ depending on access complexity, colony size, and the cap/seal work required. Chase void colonies in larger structures push toward the higher end. If a proper chimney cap or spark arrestor needs to be installed as part of the job, that’s included in the quote.

Africanized Protocol in Chimney Removals
All Clark County removals including chimney work are handled with Africanized bee protocol. Chimney and chase colonies that have been established for several months can have large defender populations. Working from a rooftop while managing an Africanized bee response requires full PPE and careful approach — which is one reason chimney work is not a DIY scenario in this area.
Call (702) 728-4423) to describe what you’re seeing. If bees are going in and out of your chimney top or around the chimney base at the roofline, that’s a colony. The sooner it’s addressed, the more contained the removal job.
