Feeding help!

I fed my crestie for the first time yesterday with a few 2nd stage crickets and I also put in some mango&banana baby food in hope that it would feed during the evening. The only problem is that when I woke up there was so sign of anything being eaten. I'm hoping to order some special diet online but I'm not quite sure what I'm going to need.

One more thing: I'm well aware that I need to remove any live food that hasn't been eaten but the crickets are too small and I have a thing about touching insects that just makes me feel sick. Is there any way of removing the remaining crickets without touching them? I know it sounds stupid but I can't touch them.

use tweesers to pick up the crickets

First thing I tried actualy but they get away too fast

with my first lizard i would just let them fall out of the box/bag they were in, infact i still do that
