Absolutely INSANE!!! These are in ALL of our houses! Get a black light and search for yourself, check baseboards which is the easiest place to find them when you haven’t seen one before so you don’t know what you are looking for. They ONLY are visible under black light and you can see them with the naked eye although if you get a clear jeweled loop 40X for $7 on Amazon you can see the details on these things much better and will be shocked at what you see!!! Another easy way is take a lint roller to your clothes and go look under black light…. They are everywhere! They are being sprayed from the sky and brought in the house through air conditioning etc… if you check the grass or your outside furniture you will see it all over it too.
