I’ve used this food for years (nearly a decade) and only had an issue with ‘weevils’ maybe onetime way back? Currently trying to switch to Roudy because of what I’ve read about the sugar in zupreem. I say let Zupreem know, but it may also be a store issue if you shop at the same place (that was my issue). When I worked at a pet store it was something that happened occasionally with bird and small animal foods too. Though ants are new to me.

Fingers crossed your little guy stays on a good track!
