1 x 12 gallon Tote.

2 x 1¼” Aluminium pipes – cut from the handle of a swimming pool scoop.
2 x 1¼” Elbow joints - irrigation fittings from local hardware store
1 x Y-Piece – from 1” PVC conduit, bent and shaped with a heat gun, then glued together.
¾” Clear PCV tubing to connect the bits together – local hardware store.



Flared ends of the aluminium ramps.



Drain pipe at the base of the bin.

Pete, great job on the BSFL bin! Did you use tilapia from your pool/pond for bait? What kind of bedding do you have in the bin? It can quickly get very wet, but I'm sure you know that. Autumn has just started here, so that means it's Spring for you, right? If temps are still below 80F, you might want to put the bin in a spot that gets a couple hours of morning sun. These grubs eat more when bin temps are above 80F. Looking forward to the first swarm of grubs photo. ha! I'm sure many here will refrain from looking.

Thanks Andrew, yes tilapia from the pond. The fish feed the grubs, and the grubs feed the fish. It's a Ying-Yang thing.
The guy at bsfblog.com says to use corn kernels soaked in water, but all that did was to attract ants.
I would think that raw liver or shrimp would also make a good bait.
They sure like the heat - still churning around like crazy in the black bin standing in full sun.
At the moment there's only cow manure and kitchen waste in the bin. I still have to figure out what they like best. The pics will be posted with a warning to sensitive viewers :-0

Pete,i tried corn.Didn't work this year.Actually smelled like someone got sick.It was worse when i knocked the container over.Next year i'm going to try cabbage.I figure one day to attract a Racoon or Possum! Have you had any critters try to come around?
Also,where you live,is it possible the BSF are active all year?

Larry, they definitely don’t operate in our ‘winter’, and these only showed up a few days ago. Apparently the grubs can hibernate for more than 6 months, so it will be interesting to see how long I can keep them going.
A mix of cabbage and manure might work as bait, but in my book you want something that really smells – like chicken giblets or such.
Mongooses could be a problem with me, but a small bin like this is easy to move into the garage a night.
I would imagine that your raccoons must be like a mongoose on steroids.
I read that BSF are actually native to the Americas, from Argentina though to Seattle & Boston. During WW II, Uncle Sam was kind enough to export them all over the world.

Back then I beleive it was part of the "Lend Lease" program. :-D

Thanks for the heads-up Steamy, I'll keep a careful eye on them.

Pete, I got an email about this discussion today, but there's no new comment. I assume this is the update: "These are possibly not BSFL grubs. They could also be Warehouse or Khapra Beetle larvae. Considered to be one of the world's worst grain eating pests."

Oh, this is the first time I've seen these pictures.
Very nicely done Peter.

Pete, I don;t think that one is a BSFL. They are a little more rounded and don't have the spines. At least the ones I have are. I like your setup for retrieving larvae though. Wish I knew all this when I had my pet store years ago.. I'd have had a great time providing even more types of live food food for the animals.

My thanks Steamyb & Pat. You guys were correct, that was not a BSF grub.
Finally, after two months, here's what I think is a genuine, home-grown BSFL.
