pinheads are tiny! they're too small to handle, for sure, but if you order 100 pinheads, they won't be pinheads anymore by the 3rd feeding. a cricket keeper is just the ticket for avoiding handling them. just tap a few into a baggie, and if you tap too many in, you can put some back, and then you dust them. fwiw, i haven't had any problems with crickets attacking my geckos, and if you make sure to only put in 5 or so at a time, i'm sure you won't either.
