Built a cyclone bucket bee vac for cutouts — design notes so you don't cook your bees
I do a handful of removals every season here in Jalisco and finally retired my death-trap shop vac rig for a proper cyclone bucket build. Sharing because the difference in bee survival is night and day.
Design: 20 L bucket with a cyclone lid (the dust-separator kind woodworkers use), shop vac pulls through the cyclone, bees drop out of the airstream into the bucket instead of slamming through the impeller. Inside the bucket: a screened inner cage with a foam pad on the bottom so they land soft. The critical part is a bleed valve on the intake hose — you tune suction DOWN until it will just barely pick a bee off comb. If it can lift a bottle cap, it's too strong.
Last weekend's cutout: roughly 3 hours of vacuuming, and when I opened the cage at the new hive I'd guess under 2% dead. With the old rig it was a carpet of bodies. Total cost about 40 USD on top of a vac I already owned. Ask me anything, and steal the design.

Can confirm the bleed valve is everything — I built almost this exact rig for Texas cutouts and my first mistake was running it wide open 'to save time'. Never again. Other tip: keep the vac runs short and shaded, a sealed bucket of bees in the sun heats up scary fast. I stop and empty into a ventilated nuc every 45 min or so.

Nice write-up. I do removals in Enugu with a similar setup and I'd add: vacuum the flying/hanging bees but move brood comb by hand into frames with rubber bands. If you get the queen in the cage, the rest walk themselves in — I always try to spot and cage her by hand before serious vacuuming starts.

Bookmarking this — I've been asked twice this year to do soffit cutouts and chickened out both times partly over the vac question. What cyclone lid did you use, and does comb honey gumming up the hose become a problem or do you just avoid vacuuming near open honey?

SourwoodGrace — any woodworking dust cyclone lid fits a standard bucket, nothing special. And yes: never vacuum near open honey, cut and drain that comb first or you get a syrup hose and sticky angry bees. Take the jobs, start with an easy one and a patient homeowner!
