packmans should almost always strike at a woundering cricket by his face, and it is unusal that your does not, but i have some advice that you can try, without the use of a flavor enhancer. When you buy a dozen or so crickets it is important that you do not feed your packman/s the full dozen because it is just to much, but in this case instead of trowing just 3-4 large crickets in your tank take the time to dust them with what ever you have as a vitemin d-3 substance, i use the minor-all indoor type, and once you have dusted them trow about 6-8 in the tank and in a way with your fingers push the crickets towards your packman so that they are with in striking distance for the packman. Now we are trying to introduce him to a new diet so please try and do this cricket trick for a week or so, and do not take the crickets out of your cage when you put them in there. do it for a week and if you don't see him eating the crickets from when you pushed them torwards him, then just let them sit in there he will adventually think that this guy isn't giving me my pinkies anymore so im stuck with these crickets and he will adventuallt take to them and you should start to knotice your crickets dissapearing in the mean time. i believe that you have spoiled your packman to the extent that he thinks that he can only live of pinkies etc. so now its time to show him other foods, just try it for a week brfore feeding him a mouse. and also make sure you feed him crickets about 5 days after you feed him the pinkie because he may still be digesting the pinkie, and just doesn't have the hunger to strike a large woundering cricket! -GOOD LUCK
