Bacteria Cult was met with generally favourable reviews from music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream publications, the album received an average score of 80 based on four reviews.[2]
AllMusic's James Christopher Monger stated that the album "needs a little time to get into your bloodstream before it can be reckoned with, but ultimately, it's an infection worth sweating through".[3] John Gentile of Punknews.org wrote: "there is a great deal of fun being had by all parties here. But, unlike, perhaps other works that reference classic styles, this is no send up or wry reference, but a sheer appreciation for the work of the weirdo masters of yesteryear... as performed by the weirdo masters of today".[4] Rachel Thompson of The Line of Best Fit resumed praising "Ipepac Recordings for allowing these two visionaries to continue to challenge the purpose and the manner of music".[6]
