Hi, when you scent the pinkies, do you wash them first? I always wash the pinkies under luke warm water very thoroughly(no soap)- lightly scrubbing them with my fingers- and then wash my hands good too, then very thoroughly scent them. Tree frogs have always worked well for me.
Another trick- if you can procure some more frogs or toads- start scenting the tail end of the frog with a pinky and hand the frog to the snake head first- this way the last taste in their mouth is of pinky. It may help get them to associate that taste with food. Then move on to scented pinks after a while.
My sierra garter was the most difficult, it took ALOT of attemps over the coarse of a year or so before he finally took pinks without scenting. Now he pounds live peach fuzzies.
You may need to go on a field herping trip to find some feeders. Sounds like a good excuse to have fun. Show us pics of what you find.
If you get a rainy night, and you live near some country roads- get out there and drive slowly looking for them on the roads. Consentrate on areas near canals,ditches, streams, ponds... Make sure you know your local herp collecting laws.
If worried about parasites in wild food- you can freeze them for a few weeks first. Helps anyways.
Worst case- you can probably order feeder frogs online somewhere-go to kingsnake.com classifieds and search "tree frogs" in the search bar. Again, I would freeze them first if it will take frozen thawed.
