Yes, hamsters can eat wax worms 1-2 times a week.
Waxworms are not good for hamsters to eat often because they can be too fatty and high in sugar.
Waxworms, (the larval stage of the wax moth), is a popular food for captive insectivores such as bluebirds, ducks, quail, and others. They may be considered nutritious or unhealthy depending on the insectivore’s nutritional needs.
Waxworms are a good source of protein, however can also be high in fat and sodium.
In addition, they have twice as much sugar as protein, which is not considered very healthy for hamsters to eat too often.
This is especially true if your hamster is elderly or obese.
They are also high in calcium, which can be good or bad depending on whether your hamster has loose stools.
There have been some studies done on domesticated wax worms, but not much information is available specifically for their use as an insectivore food source.
If you want to offer wax worms to your hamster occasionally, be sure to remove any uneaten worms so they do not spoil or mold.
If you want to offer wax worms often, check with your veterinarian before doing so to make sure they are healthy for your specific insectivore.
