We had a cold snap at the beginning of spring. The overnight temperature was 10°C (50°F) and three flies eclosed in the morning.
Can it be that they work on an internal clock, and not a thermometer...??

When you move to bigger bins you'll probably find that your ramps are too skimpy. I found that 1¾" PVC Cable trunking is incredibly useful stuff to have around.

Thanks Nicolas, your 2nd article is well worth a read.
How about this possibility: hatch the eggs and keep the baby larvae at around 10° C? I've only done one rough test, but it did look promising.

They will lay their eggs almost anywhere, but it's better to use egg traps. With traps, you can collect the eggs and hatch them somewhere else, like in a BSF nursery.

No, it's to prevent the drain from getting blocked. You sometimes find 4-5 grubs crawling through hole, but they are not suicidal.
If they do come out in large numbers, then you must know there is something drastically wrong inside the bin.

Cover your drain hole with something like this, and you've got yourself a pretty good system ;)

Hi Altidore,
It's also important to have good drainage. If your bucket gets smelly and anaerobic, the grubs will die.
Fresh food is not the problem. They do eat rotten food, but if you give them a choice, they'll go for the fresh stuff.

BTW, grubs can also get over a lipped barrier. If there are enough of them, they build a ramp into one of the corners.

Jerry, the jury is still out on the glue. Our nights go down to 50 F, so my lot are almost dormant. The crunch time comes in Feb-March, so you'll probably know before me.
However, from what I have seen, I'm cautiously optimistic. :D

.....if one wants to maximize the harvest of mature larvae it's required to mend the gaps and tunnels that form in the Velcro.

How about this: Cut a thin strip of acetate sheet and glue it underneath the vecro. It should neaten up your blisters and bubbles ...??

One of these days I'm going to raise a small batch of grubs on 100% coffee, and compare them to batch raised on general kitchen scraps.
It will have to wait until next summer though, my grubs are almost dormant righ now.

Okay, here's a corner in one of my bins. As we know, a grub has only one pupose in life, and that's to chew through barriers.
It's going to be interesting to see what they make of the hot melt glue. :lol:

My problem with velcro was simply this: The velcro I used was made from Nylon , and the bin was probably Polypropylene . The two materials had different explansion rates. Invariably, the adhesive would separate after a few weeks of heating and cooling. Short pieces, ie. lots of expansion joints, was...

Has anybody discovered a good adhesive for plastic bins? :roll:
This stuff works fairly well [link], but only as a crack filler. It sticks pretty well to aged plastic, but new plastic needs to be roughened with sandpaper.

I have also noticed that feeding grubs molding bread is also not a good thing.

GrownLocally mentions his concerns about moldy bread. When you Google Aspergillus flavus [link] , you'll see it's not something you need in your bin.

Your one looks more like a Garden Soldier Fly. They are reported to be very common in Austrialia.
