How I feed mealworms: starting off with a few hundred (4.00 per hundred) using a shallow and wide bin I feed the wormies oatmeal, fruit and veggies to gut stuff them. Also encourages breedingm beetles get their own container with wood and such for the eggs to cling to. He is fed 30 mealies a day - so 100 only lasts 4 and some days. It does get pricey!! Bulk is better too... And cheaper.
Believe it or not, their diet is not supposed to be mostly insects. It is mostly fruits greens! Lettuce he loves although has no value... He LOVES strawberries and LOVES LOVES LOVES sweet potato.
As for the bulbs... We have a 50 watt sun glo and a red light for night. They do not really need that night light though... Just keep the temperature decent.
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
