Lead vocalist Jacoby Shaddix said about
Infest in 2015: "That's a solid fucking record, man. That record is a snapshot of who we were as young men, and I feel that there was a huge purpose in that record. That record took us on a wild ride across the world, and we sold a shit ton of records. It put a stake in the ground: 'P. ROACH is here'. I look back on that record, and I'm very proud of it." In August 2016,
Loudwire ranked the album at #1 on their "Papa Roach Albums Ranked" list, saying, "The brutally honest and aggressive lead single "Last Resort" became the band's signature song, while "Broken Home," "Between Angels and Insects" and "Dead Cell" kept the rising rockers on the airwaves for the majority of the next year, helping to cement their status as one of rock's brightest new acts." In June 2020,
Kerrang! included
Infest on their "The 21 greatest nu-metal albums of all time - ranked" list, saying, "Jacoby Shaddix's Californian mob didn't just deliver an angst overload – they unleashed every ounce of feeling via arguably the catchiest songwriting nu-metal would ever see." To commemorate the album's 20th anniversary, Papa Roach performed the album live in its entirety in studio to stream worldwide on June 20, 2020. The whole performance was released on
YouTube on September 15, 2020. In April 2022,
Louder Sound ranked
Infest at #18 on their "The 50 best nu metal albums of all time" list. Eleanor Goodman said about the album, "the lyrical content was surprisingly heavy coming-of-age stuff for a band whose singer went by the not-exactly-serious name of Coby Dick." In September the same year, the publication ranked the album as Papa Roach's best, saying "It might not be their most diverse piece of work, but
Infest is undoubtedly Papa Roach’s finest moment." In January 2025,
Loudwire ranked
Infest at #20 on their list of "The Top 50 Nu-Metal Albums of All Time (Ranked)", saying: "The multi-faceted sound throughout the record allowed the band to experiment, involving rapping and funkier beats to a larger extent than many of their contemporaries." In February 2025, Megan Jenkins of Distorted Sound Magazine said about the album in a retrospective piece, "It earned them a Grammy nomination, multiple Platinum plaques, it’s hailed as one of the greatest nu-metal albums of all time, and it’s featured in multiple video games, tv shows, and movies. It feels as though everyone should have heard something from this album yet a full quarter of a century later, audiences discover PAPA ROACH because of Infest." The same year, Rae Lemeshow-Barooshian of
Loudwire included the album in her list of "the top 50 nu-metal albums of all time", ranking it twentieth. In 2025, guitarist
Jerry Horton said about
Infest: "we expected that the songs that we picked for singles would do well and we expected that we would be on the radio and we would be touring. It just didn’t happen the way that we imagined it would happen. We expected a build up, we expected to work it, to tour for a while and hopefully get to a certain level but it was completely different." ==Track listing==
