There are so many things you can do. Personally I would use something other than the cricket box with your none feeders the smell from the crickets, which is likely still in the box, may be turning them off. I would use a tuperware, with air holes.
Here are some suggestions. For each thaw pink by filling a bowl with the hottest tap water you can get and placing the pinkie (in a ziploc) in the water. No need to try these in any particular order.
1. thaw then brain, cut open the back of the head of the pinkie and squish some brain matter out.
2. thaw then dip in tuna juice.
3. thaw then rub on raw chicken.
4. thaw then rub on KFC skin grease.
5. thaw, brain and place feeding container in viv and leave all night(not on warm side).
6. thaw, brain and cover with a tea towel, no peaking for at least an hour.
7. thaw, then tease feed, gently bump pinkie into the side of snakes neck to aggravate it and get it to strike at it, in the hopes that it will get the mouse in it's mouth and then decide to eat it.
8. thaw and wash with dish soap to remove any smell.
9. thaw and scent with a different rodent, get some bedding from a pet store and rub it around in it.
10. thaw and scent with lizard, either alive lizard, frozen lizard or a product called lizard maker.
11. try live one day old pinkie.
12. thaw and put pinkie and snake in a paper bag that is somewhat sealed (so snake can not get out) and place in the viv, for a couple of hours or over night.
13. take the snake for a drive (in a sealed container covered so the drive does not stress them out), aparently some have had luck with this motion stimiulating the appetite
That's all I can think of right now, sorry.
