Get Rid of Moth Worms

Moth worms are the larvae stage of a moth, which occurs just after moth eggs hatch. Moths like to lay their eggs near clothing and food pantries because these places offer lots of food options for the larvae to munch on once they hatch. If you’ve found moth worms in your clothing or kitchen, then you know the damage their munching can cause. Fortunately, you can get rid of moth worms by repelling moths, cleaning out your closets and wardrobes, and dealing with pantry moth worms.

Steps

Repelling Moths

  1. Use anti-moth paper or strips. You can purchase anti-moth paper or paper strips that can be placed in your wardrobe, drawers, boxes, garment bags, or pantry. This paper will kill the larvae and the moths.[1]
  2. Place cedar balls anywhere you store clothing. Cedar balls are a great natural replacement for pesticides. Cedar contains an oil that kills small moth worms, but they don’t have much of an affect on larger worms or adult moths. Hanging a cedar ball in your closet or laying one in your dresser drawer can help, though it won’t solve all of your problems.[2]
    • You can also use cedar hangers.[1]
  3. Use mothballs. To be effective and safe, your mothballs should only be used when you’re storing your clothes in an airtight container. Place the mothballs in with the clothing, then seal it off. Mothballs do not work immediately, but they contain chemicals whose vapors that can build up and kill moths in all stages of their life cycle.[2]
    • Wear gloves while handling mothballs because they can be toxic.
    • Mothballs don’t work well in closets since the vapors need time to build up in an airtight container.
  4. Add bay leaves to kitchen cabinets. Moths naturally avoid bay leaves, which many people keep in their kitchen already. For an easy and safe moth repellant, lay out a few bay leaves in your cabinets and pantries.[3]
  5. Make your own herb sachets. Moths tend to avoid the smell of lavender, peppermint, cloves, thyme, and rosemary. Place your dried herbs in a breathable bag, and then add it to your closets, drawers, and storage areas. The scent of the herbs will ward off the bugs.[4]
    • You can use one herb or a combination of the herbs in your sachets.

Cleaning Your Closets or Wardrobes

  1. Remove the items. Take everything out of your closet, including non-clothing items like shoes and storage items. You will need to clean everything, so if you have things like shoe storage racks or organizational items, remove those as well to enable you to thoroughly scrub them.[1]
  2. Vacuum out the closet or wardrobe. Use an attachment or a handheld vacuum to clean the floor, walls, shelves, and ceiling of your closet. As soon as you finish vacuuming, empty the contents into a sealed bag. Remove it from the house immediately.[1]
    • Make sure that you get the corners and ceiling of your closets.[2]
  3. Wash walls and shelves. Pour soap or detergent into a bowl or bucket, then fill it with water. Stir the water to mix in the soap. Dip a clean cloth into the soapy water and use it to wipe down the walls and shelves. Continue to dip the rag into the water as you clean the entire closet.[1]
  4. Wash your clothes and other fabric items. Set your washer on the hottest cycle because the larvae can’t withstand the heat. The water should reach about 120 degrees Fahrenheit (48 degrees Celsius) in order to be fully effective. Allow the clothes to cycle for 20 to 30 minutes to ensure that all the moth worms and eggs have been killed.[2]
    • Dry cleaning will also kill the larvae.
  5. Freeze items that you can’t wash. Larvae can’t survive freezing temperatures, so the freezer makes a great pesticide. Place your items in a protective covering, such as a plastic bag. Put them in the freezer, allowing at least 48 hours for the cold to kill any larvae on the item.[1]
  6. Avoid putting worn clothes into your closet. If you plan to wear clothing more than once, find another location to store it until you are ready for your second or third wear. Moths prefer clothes that have sweat or food on them, so they act as a moth magnet.[1]
  7. Store clothing in airtight containers. Keep the moths from laying new eggs by keeping clothes that you don’t wear frequently in airtight containers.[2]
    • Easy to use options include sealed storage boxes, vacuum-sealed bags, and plastic storage bags.
    • For added protection, apply packing tape over the seals.

Dealing with Pantry Moth Worms

  1. Know the signs of an infestation. Look for tiny worms that look like wiggling rice, along with webbing that occurs in either food containers or the pantry itself. You should also notice cast off skins from the moth worms shedding. Check your corners and in the dark areas of pantries for moth worms and cocoons.[3]
    • The worms will grow to about ⅔-inch size (1.7 centimeters), and they have a black or brown head.
  2. Identify the source of the moth worms. When moth worms have infested your pantry, you’re more likely to notice their effects before you see the larvae. Kitchen moth worms, which are usually Indian meal moths, enter your home in the food that you purchase.[3]
    • Foods that the meal moths prefer include cereals, flour, grains, birdseed, dried fruit, candy, pet food, dried herbs, nuts, and powdered milk.
    • Most items are not infested with moth eggs.
  3. Check other foods to see if they’re infested. Go through your pantry, checking items for signs of infestation. You will notice the moth worms, egg casings, or webbing. Even if you don’t see any moth worms or casings, webbing means that the food is infested.
  4. Place infested food items in a sealed plastic bag. Keep the moth worms from spreading by sealing them in a bag. The moths cannot penetrate the seal.[3]
  5. Remove the items from the home. Throw away the infested items as soon as possible, removing them from the home. Don’t allow the infested foods to sit around, even if you’ve placed them in bags. While the moth worms cannot break the seal, it’s possible that you may not have properly closed all of the seals.[3]
  6. Sort your remaining food. Unfortunately, most of your food will need to be thrown away. Any food that the moths would normally eat, such as grains or cereals, should be thrown away. If you have any food that is in a container that you cannot wash, then you will need to throw that food out as well.[3]
  7. Wash all items you plan to return to the pantry. The moths like to lay eggs in the crevices of items that are near good food sources for the larvae, so you may still have active eggs on your pantry goods. To avoid a reinfestation, you need to wash these items well in warm, soapy water.[3]
    • Check crevices such as jar lids or flaps on items wrapped in plastic because the moths may have laid eggs there.
    • If you are unsure of an item, it’s best to throw it out. A reinfestation after you’ve replaced your pantry items will be worse than losing a few questionable items.
    • You can also kill moth eggs and larvae that may be on the food by putting the food in the freezer, microwaving it for 5 minutes, or baking it at 140 degrees Fahrenheit (60 degrees Celsius).[3]
  8. Replace your shelf liners. If you have any shelf liners, then you will need to remove them and throw them away, as they can harbor eggs or larvae. If you plan to place new pantry liners, wait until your infestation is completely gone before putting them down. Otherwise, you may have to replace them again if the moth worms come back.[3]
  9. Vacuum out your cupboards. Use a hose extension on your vacuum cleaner to vacuum out any visible moth worms and crumbs. Vacuum in the crevices and corners, if possible, because tiny worms and eggs tend to hide in the darkest spots.
  10. Wash your pantry shelves and walls. First wipe down all surfaces, including the pantry walls and ceilings, with a soapy rag. Follow with a mild bleach solution. You can either make your own or purchase a cleaning product that contains bleach.Afterwards, spray the shelves with plain white vinegar and wipe everything down. These measures usually kill moth worms as long as these solutions come into direct contact with the insects.[3]
    • To mix your own bleach solution, add 1 part bleach to 9 parts water.[5]
    • Don’t forget to scrub down the corners well.
  11. Clean out your food containers. Run the containers in a hot dishwasher if you have one. If not, wash them out thoroughly by scrubbing them in a bath of hot soapy water. Finish by applying a vinegar rinse. You need to follow these extra precautions because a single moth worm hiding in one container could re-infest the entire area.
  12. Use airtight containers. Prevent a reinfestation and the contamination of new foods by storing your food in airtight containers.
    • When you buy grains, flours, or meals, you may want to store them in the freezer for a week to kill off any eggs that may already exist on or in the product.
    • You can also refrigerate items until you use them.[3]

Tips

  • Wash all second-hand and vintage items before adding them to your wardrobe or attic.[2]
  • Moth worms enjoy natural fibers like cashmere, wool, cotton, silk, feathers, and shearling.[1]
  • Moths have a 10-day lifecycle.
  • If you suspect you have a moth problem but haven’t seen any larvae, you can use a pheromone trap to lure any male clothing-eating moths. If you catch moths, then you may have larvae.[2]
  • Airtight containers are great for keeping out moths and larvae.
  • While people usually think that moths are eating their items, moth worms (larvae) are the biggest risk to your clothing and food.
  • Don’t put dirty clothes into your closet, drawers, or storage.
  • Moths hate light.

Warnings

  • While cedar can help with a moth infestation, it’s only useful when the scent is strong. Use multiple cedar balls and refresh them often.[2]
  • Avoid using chemical moth sprays in areas with food. These chemicals are often hazardous to people as well as moth worms.
  • It can take up to 6 months to get rid of a severe moth infestation.[3]
