I feed my crickets exclusively on fresh greens, vegetables, and fruits. Kale, mustard greens and acorn squash are my main items, and they also get scraps like zucchini ends or whatever other suitable vegetable/fruit kitchen scraps I have on a given day.
Jerry, crickets will eat about anything.....
probably do the cloth off your couch,
But assuming they will go into the mouth
of a gecko........Feed Them Healthy.
Many, many, types of people food.
Cereals, fruits, vegetables, meat, grains
Take care. HJ
