This is a question.These approximately 4 mm long bugs we found 2 weeks ago. A few under bed against the wall on 1 year old fitted poly... carpet. Others found on window sill, on carpet by window and behind bedroom door. Several were put in a clear plastic box 2 weeks ago. They are still alive and crawling around.
Please would you identify them and suggest treatment? Many thanks!
These are the larval stages of a dermestid beetle, to be precise of a species of the genus Anthrenus or carpet beetles. It could be the most common species Anthrenus verbasci, the varied carpet beetle, a household pest. The larvae live on anything wolly, furry, and dry organic matter and can become a real nuisance if they turn up in large numbers. They usually only turn up as a few individuals and you can throw them outside and forget about them. If they continue to turn up in larger numbers, though, you should search for the source that sustains them. As you don't have carpets made from natural fibers, the carpet can't be the source.
