Yes, you can very easily freeze our mealworms. If you place them in a gallon-sized freezer bag so they are at an equal depth when the bag is on its side they will freeze so that you can easily remove the amounts you want from the bag.
It is not inhumane to freeze mealworms, they will go dormant (to sleep) once they reach 42° and won't know that they are being frozen or feel any pain.
Your frozen mealworms will be more fresh than had you purchased them pre-frozen, and you will know you are using healthy worms.
