What are these?
Hi! Can you help me identify these cacoons (?) They are stuck to the outside of my house, and I believe are also responsible for destroying this expensive rug! Are they a type of moth? Is there a good way to control/remove them? Thank you!
Hennepin County Minnesota
Thanks for the question.
Unfortunately your pictures lack the necessary clarity and resolution from which to make a precise identification. I am also puzzled by the fact that in one of the pictures, these bugs appear quite small and black. In another picture I see what appears to be something white. I don’t know if you are dealing with two different types of pests or just one. There is a beetle in Minnesota called the “Carpet Beetle”. It can cause damage to carpets. The following will give you information about this particular beetle as well as some other images that you can compare to what you are observing:
If you are able to get more distinct pictures, please send them to us. Also, if you have additional questions we will attempt to answer them.

One additional response.
Upon consultation with another Master Gardener, we believe that these are bagworms. They are a type moth although the adult moth does not have wings. The larvae encase themselves with plant materials. Although they can cause damage to various plants, they appear to do no damage to the inside of a house. See the following for more information:
