Currently dealing with carpet beetles, more specifically their larvae. They like to eat things like hair and also anything made out of natural fibers. They’re also extremely small. I noticed them when I emptied the laundry basket and after staring at them for a moment realizing that they were bugs, they started moving. I have hardwood floors and I keep finding them. I sweep the floor with a broom into a white dustpan and stare at it and then after 30 seconds or so I see movement. One or two each time, everywhere all over the house. I found a forgotten hair brush under the couch and there was one in there. They’re completely harmless except that they will eat holes in your clothes. They take a long time to go from larvae to flying beetle. They can also survive without eating for 30 days. The original beetle could have just flown in from outside or came in on fresh flowers. They also like women’s underwear because of the pheromones. The eggs must have been in a piece of clothing and then got spread around the house before hatching.
