Hello,
I am new , but I do know a lil about red wiggles . They are amazing creatures. For the smell u have to make sure to feed them the correct amount . They can eat half there weight in food per day . I have a pond of worms so I feed um about 2- 3 pounds a week. One time feeding. If u over feed that is when u get the smell. If I do use banana peels small amount and bery them deep. U will have fruit flies very quick. For the egg shells make sure u double boil. Hard boiled eggs, peel m and boil m agian . Make sure after u boil m to take that thin membrane off . Can kill m. Moisture is a problem . If it is too moist then u can have soil- mites. Moisture and coffe grounds make the bedding acidic. U can counter it with egg shells, They thrive in it. Kinda of sucks because coffe grounds make m sexually active. And u want them to produce . Just have to keep a balanecd eco system. Once u find ur balance All u have to do is feed m the correct amount for the worm population you want. They self regulate there population. I started with 60 . I was surprised how much the pop. Has grown.first pic is the white mite eggs I was talking about , second is when the worms are in heat, third is the worm eggs .* picture I posted is matchure eggs, Immature eggs clear in color and darken as they progress , last is my bin. I keep it in my office ( indoor).
