Hi aegillesp,
I switch up the use of 4 different products. ( calcium and vits)
My tree frogs eat most food offered when they are dusted with " Repashy calcium plus" ( calcium and vits supplement)
Repashy Calcium Plus ICB

I really believe it has something to do with the smell? Give it a try?

For crickets-use a smaller size cricket and bowl feed !
Here is a pic of my cricket bowl. ( 1.75 qt) clear glass 'Pyrex'.

This bowl is shared by four red eyed tree frogs each night.
Only one little cricket left in there from last night -- must have been a hungry night !

As for calci worms and wax worms---I don't use calcium worms.(Phoenix Worms or Soldier Grub)
I have read too much about digestive difficulties

I do culture wax worms ---for the moths--- my tree frogs go wild over them !
They are very east to culture. The culture medium smells nice, too !
