In addition, they can be seen as an indicator of moisture (leading to fungal/mold) issues. As Tony says, just a few are not too much of a concern, many indicate a more serious issue, possibly water leak of some kind.

CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe. Hi Katy This is not a Cigarette Beetle (Lasioderma). I think it more likely to be one of the Cryptophagidae or Mycetophagidae (sometimes called the Minute Fungus Beetles). They often crop up when newly plastered walls develop a coat of fungal mycelia as they dry. So recent building work might be the source. Alternatively they can be found in birds' nests, on dung, rotting wood, fungi, compost, etc. If you only find the two, regard them as accidental visitors. If lots more turn up, it could indicate a building problem.

Hello wise pest folk, Doing our IPM rounds and came across these beetles. Two of them in the same trap. The closest ID I can find is a cigarette beetle. Can anyone confirm? If not cigarette beetle, then what? I’ve taken multiple photos since the depth of field on our imitation dino-lite is pretty terrible. Note the red marks are mm on a fabric tape measure so these are < 2 mm long. Thank you for any ID help.
