If he is striking, but not holding on and coiling, this is most likely a defensive strike, not a feeding response, so maybe he feels threatened by something. I have a few girls that will strike defensively at prey if I'm around, but eat fine once I leave them alone with their food. If using those wipes are the only thing that you've changed husbandry-wise lately, maybe try not using them for a couple weeks, and try feeding again. Don't worry too much about him not eating right now, as it has only been a couple weeks. If he ate well before, he will eat well again, as long as all his other needs are met. Hope this helps.
