2. Can you see bed bugs?

Bed bugs are certainly visible with the naked eye and are not to be confused with dust mites.

Adult bed bugs can get to be 6-8mm long (about the size of an apple seed). Bed bugs have five juvenile stages called nymphal instars (each progressively larger than the next). The first nymphal instar is about the size of a pinhead. The fifth nymphal instar is approximately 4.5mm long.
