Wax worms for leo?

[Icefire]

I got 11 gecko, some babies, some 5 months and 3 adults
House gonna crickets every where if I don't swith that.

since they can easyly eat 20-30 cricket each a week, would it be
good to feed them 3-6 wax worm each 2-3 days and give them cricket
sometimes?
or is there something else I could give them but not cricket as
regular diet?
