"Carpet Beetle Invasion"
Spring has arrived and you may have noticed tiny, dark, round bugs crawling up your walls. If you look very closely you'll see that they are beetles. These tiny beetles are only about the size of a pin head and are known as carpet beetles.
The carpet beetle's life cycle often requires an indoor and outdoor stage. The larval stage is the damaging stage that feeds on wool, hides, hair, dead insects, food crumbs, household lint, and general detritus. The adults, however, feed on the nectar and pollen of flowering plants. This is why they are climbing walls, they are moving towards the light looking for a way to get outside. This is also why you do not see them until spring when plants are starting to flower.
When the adult beetles emerge from their pupal stage in early spring they are attracted to light at first, and they can actually fly.
