BLACK SOLDIER FLY LARVAE HARVESTER
Lot’s of ways to do BSF. Here are a few that we do in the Philippines for year-round grubs. Combine upper big with lower little (your upper little can combine with another lower smaller still). I’ve used 120 Liter/80 Liter, 80 liter/45 liters successfully but check for compatibility before you buy! I hope you can follow my graphics.
Make sure your rack holds everything if you want self harvesting
Use a filler that is available that you are comfortable with- cement with perlite, body filler, epoxy, etc.
Make sure your 35º evacuation ramp is sealed, drainage of leachate is adequately sloped
Rack system with room for leachate collection
Don’t forget the nursery! Females lay eggs in corrugated material on the underside of the lid. Leave holes for the entrance of pregnant females.
Let 1-2% hatch under ideal conditions to assure perpetual propagation. We use a small pupating chamber for the new generation to come online
Use a simple method to start if you can’t copy the above model
