Before I go ice fishing for bluegills, I always like to treat my waxworms. No, I don't take them out to McDonalds, then to the movies.
Rather, a few days before I go fishing, I will buy a tub which contains 250 packed in saw dust.
I then treat the tub with Dr. Juice panfish scent.
Squirt about 20 drops into the saw dust and stir and shake it around gently.
No need to drown or saturate them.
I then store them on the basement cement floor, keeps them cool and they will last for several days. Just as long as untreated waxies.
Every day, I will turn the tub over. We all know that once they settle, they always like to crawl to the bottom. Turning them will make them crawl back through the treated saw dust, thus rubbing the scent all over them.
This extra time, allows the scent to absorb into their skin. Will not wash or rinse off as quickly if you just give them a quick shot before dunking them.
When ice fishing in shallow water, site fishing, have noticed that gills will hold the treated worms in their mouth a little longer and sometimes, that extra second is all you need to hook them.
If you can not find Dr. Juice scent, then go to your local pharmacy and buy a small bottle of Cod Liver oil, yes, the same as your grandma gave you as a kid when you got sick. This is just as an affective scent additive and maybe a little cheaper.
Found this works just as well during the open water season.
I believe treated waxies will out perform the untreated.
