You can feed them directly, but if you want to be as safe as possible, I would wait for malted worms and take their heads off.

Other tips:

Feed the mealworms healthy food to 'gutload' them. Fresh vegetables will do
Keep the mealworms healthy and in good condition
If you have a sterilized floating object/toy/wood, you can put a mealworm on top of it and watch the frogs work for their food. I do this with a small piece of driftwood I am soaking in the tank. I believe it stimulates the frogs more than always being handfed.
Even the mini ones? I'm talking about super fine, thin guys that feel pretty squishy to the touch.
