I had a batch of Blue Bottle Fly spikes tip over on the carpet and didn't notice it. When I finally saw it was too late. I collected all I could, but a lot of them burrowed into the carpet. I didn't really know how many got away until they hatched. OMG! It was A LOT of flies. They were...
I sell them when i have excess. I never count them out, but sell them in a 3.5oz cup for $6. I guess it would be a couple hundred.
This is an old add I placed. I now have spikes OR pupae, not mixed. https://www.chameleonforums.com/blue-bottle-spikes-pupae-sale-trade-91863/
Hatching pupae do not stink. I raise my own and the only real stink is raising the maggots. Once out of the medium they should have little to no smell.
