Mealworms are easy to grow at home. These come in two sizes -
small and giant. I like the small's, but I have a buddy who
grows the giant's. Get a new 5 gallon bucket (no lid). Buy
these from your fast-food places for around $1.00. Then go to
the bait shop and buy a couple of boxes of the size mealworms

Quaker Oaks will do. I now use hog brand meal. We buy one
hundred pounds (several of us split it) for $6.00 from a farm
Now fill the bucket about 1/4 full of meal. Dump in the worms
(the more you start with the better). I got about 1,000 from a

now, plus a cup or two of meal. Leave old stuff in bucket. The
stuff that looks like powdered residue are eggs -that's your
This process takes a couple of months, but you will have worms
of all sizes, black bug and grubs eventually. I fish with the
worms and grubs. I ice fish mostly with the grubs and smaller
