We recently received the following inquiry from a reader, “How do you know when they’re gone or all out?” We aren’t exactly sure what our reader means by this question, but we will proceed with a potential answer.

If our reader has recently dealt with some sort of larval infestation, such as drain flies or carpet beetle (two of the most common), perhaps they are curious how they can determine if these creatures are gone. If they no longer see the flies or larvae, and they are not noticing other signs (such as holes in their garments if they were dealing with carpet beetle larvae) then it is safe to say they are gone, especially if they have cleaned thoroughly.

It is very possible our reader is looking for a different answer or explanation, but due to the vagueness of the question, we don’t know for certain. We highly encourage our reader to post another question with more detail so we can help them out more thoroughly!
