Carpet Beetle Health Concerns
Carpet beetles are incapable of biting a human in any perceptible way. Their mandibles are not large enough to inflict a painful bite and they carry no venom. Due to this there are virtually no health concerns from being bit by a carpet beetle.
However, there are potential health concerns when the beetles gain access to human foods. Cross-contamination can become a big risk in these food situations and this should be taken seriously.
