When selecting a garment bag, look for designs without significant gaps. Bags that are open at the bottom or have large spaces around the zipper, gusset, or elsewhere are not going to protect your clothing from moths well. Almost all garment bags will have a small opening at the top for the hanger, however, so if you want to be extra-secure, it’s a smart idea to tape that closed after you’ve slipped your clothing item inside.
The next thing to consider is the material of the garment bag. Many garment bags and other storage options are made from plastic. While plastic has many benefits like being cheaper and typically see-through, it is not breathable. PEVA vinyl and non-woven fabrics are popular alternatives because they're breathable and durable while still providing protection from moths, dust, and water. Regardless of the material you select, be sure to wash or dry clean the items right before storing them. This makes sure any moths, larvae, or eggs are dead. If you don’t, the pests will be trapped inside the bag with your clothing, giving them easy access to munch right through your stored items.
Finally, consider the size of the garment bags. With different lengths to choose from, getting the right length makes it a lot easier to avoid wrinkles.
With all of these considerations in mind, I scoured Amazon to find the highest-quality garment bags that will help keep moths away.
