The bad news - yes they lay eggs and will become adult moths. The good news - if you remove all wool garments from the closet, stick them instantly into plastic bags and then put mothballs in the closet for a short time, the moths should be gone within a not-very-long-time (can't say what that is for your problem). It's wool they're after and very little else. You can get the clothes dry cleaned, but then you could end up with the same problem. I personally have never bought wool since I had a similar problem (started in a 100% wool rug actually and moved to our clothes).

Hi, forgot something - you don't see them because they work at night and if they have what they want in the closet, won't come out to say hello. Haven't attacked your clothes because they're probably not wool.

As larke said, Moth Balls, they are very inexpensive in the laundry section of any grocery or drug store.

My husband is also a pack rat. He is 50 years old and I thank God that his high school gym shorts fell apart 10 years ago.

If I were you, your husband didnt wear the clothes for years. Tell him they are infested and have to be thrown away before the moths breed.

They could be carpet beetles. If your husband wants to keep any of the clothes that have not been eaten yet, have then drycleaned and then store in air tight plastic bags. We had to take all of our persian carpets to be cleaned.

Since you have not seen the bugs, it is hard to know what they are. Some eat silk as well as wool.

I'm sorry this is happening to you. It is a hassle, and expensive.

Don't use moth balls, it's very difficult to get the smell out of your clothes.
Take all dryclean items to the drycleaner and launder the rest.
Then after all clothing is clean. store your woolen item in a closet lined in cedar planks, a natural repellant.
If you are renting, you can get cedar planking at Home Depot and Lowes and just lay it on the shelves.
