I have found some herbal moth repellent sachets. I don't know if they work, though. You might try the moth traps, too. I use them in my pantry. They DO work. http://www.pantrymothtrap.com/ Everyone swears by bay leaves in the pantry, maybe if you hung nets bags full of bay leaves in your closets it would repel critters. Spiders, I don't know a natural solution. When I moved into this house 21 years ago it was infested with fat little brown house spiders of some sort. In the summer they would come out at night and crawl up the walls and the ceiling. I found one swimming in my bedside water glass early one morning. I finally resorted to pest control but only on the outside of the house, never inside. After a while I had no more spiders. Here is a link that might be useful: Moth repellent.

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).

I've ignored two warning signs about moths. One was SEEING them! And the other was having a sweater that kept getting holes in it. I put lavender and some cedar in my closet but the holes continued. I called a pest control company and the woman told me there was nothing they could do. She said the only solution was to take every single thing out of my closet and dry clean it or wash it...all at the same time. She also told me that I had to use MOTHBALLS which I know are toxic. I have a new grandson who comes here. Plus I sleep in my bedroom and don't want the smell on me or my clothes. I'm wondering if the holistic methods work to get rid of the moths or they simply repel them. Has anyone tried using that thing that sucks the air out of plastic bags in which you store things... that is after your stuff is clean? Also what do moth larva look like??? Why am I seeing them flying around my computer in a room that has very few clothes. And... if you cleaned out your closet, did you do EVERY closet in your house???

The only carpet we have on our main level is in our master closet. We didn't do it for cost cutting measures, just that we liked the idea of carpet in the closet. It doesn't look odd at all. The only suggestion I would make, should you decide to carpet your closet, is to be sure your vacuum cleaner can go under your closet system. Some of our units are a little too low and I need to put a nozzle on the vacuum hose and vacuum that way. Otherwise, I vacuum the entire house whether carpet, hardwood or tile, so not an issue to do the closet.
