* First try an empty container, small shoebox type rubbermaid, so it's just her and the crickets. If she catches them right off then just feed her in there and then return to her cage. Her home will stay nicer too.

* A few other things.....Bordem, just act out and do nothing, kind of lazy until they really get hungry.
* Some just are lousey at catching them Clutsy.

* Check eyesight, How are her eyes , does she turn to look at things, make some movements and see if she notices you moving something.
