Pantry Moths in Dog Food & Other Pet Food – What to Do

By: Lisa Dingeman

How They Get There

The moths that you find in pet food, as well as other dry goods and foods, are typically Indian meal moths. These moths and other bugs found in dog food usually make their way into the home through the food packages themselves. The bag or box of food most likely became contaminated while it was at the factory or warehouse. Spoilage can also happen while food packages sit on a shelf in an infested environment such as a storage facility or during transportation.

Why They Are Attracted 

Pantry moths are attracted to dog food and other dry pet food because their eggs can be hidden easily. As soon as the moth eggs hatch into larvae, their feeding stage, the scavengers are right where they need to be – close to a food source.

Noticing an infested bag of pet food may be difficult. The moths are likely to still be in their early egg stage which means they will be harder to spot. During the egg stage, they will only measure about 1-2 hundredths of an inch. After hatching from the eggs, the larvae will measure up to ½ an inch and have a worm-like appearance. If you are not inspecting the food, which most of us aren’t, you will not recognize a moth problem until you spot an adult flying around.

Once you see an adult moth, it has already gone through a large portion of its life cycle. It’s gone from egg to larvae, and pupa to adult—with a female adult having the ability to lay up to 400 eggs within 2 weeks. Clearly, detecting or preventing a problem is important because these pantry pests can reproduce so rapidly!

What to Do About Moths in Dog Food

If there are clear signs that moths have been inhabiting your dog or cat food (or any other family pet), the food should be sealed up, thrown away, and a new bag should be purchased. Sealing up the package before disposal will help ensure that other food items will not be contaminated as well. 

If there are other dry pet foods nearby the moth infestation, or food items that are in contact with the infested food, be sure to check them thoroughly. This is because the adult female moths continually sniff out the perfect place to lay their 400+ eggs. If you see similar signs, unfortunately, it’s best to throw out those items as well. If they show no signs of any critters, we recommend freezing the food for a week to kill any remaining eggs, just to be safe.

Don’t panic if your dog eats food containing moths at any stage of their development. The good news is that pantry moths are not known to carry any diseases that will harm you or your pet.

Although they are not a significant health risk, these flying bugs are still unsightly. If the thought of serving your furry friend infested food sends shivers down your spine, take the time to check for a moth presence when purchasing new food:

  • Sift through the first 4 inches of the food and carefully inspect it. They rarely go any deeper than 4 inches from the surface. 
  • Look for tiny white eggs, worm-like insects, casings, and white webbing–like that of a spider web. The webbing is formed when the cocoon is spun. Once hatched, you will notice the empty moth casings.

Prevent and Get Rid of Moths in Pet Food with These Natural Solutions:

  • To prevent moths from inhabiting your pet’s food, dump the entire bag into an airtight container after thoroughly inspecting it. Any others nearby will not be able to sniff out or gain access to the food and will move along.
  • Keep any other dry food that is in the area in a sealed container or a freezer, if it’s freezer friendly.
  • Promptly recycle or remove any boxes or food packaging that it came in because moth eggs may be hidden under the seams or inside the corrugate of cardboard boxes.
  • Clean up the storage area where traces of pet food may be present. Vacuum and wipe away any crumbs in the surrounding area. Doing so will eliminate any attractants that may lure them into the space.
  • In addition to cleaning, place a pouch or two of EarthKind®’s Stay Away® Moths wherever pet food is stored. Two pouches per room is recommended for the most effective prevention. The pouches work by using a blend of essential oils that smell offensive to moths, but pleasant to humans. The scent obscures the food aromas and other odors that they seek out when looking for a safe place to lay eggs. Avoiding chemicals is the key goal when dealing with your loved ones and fur babies. Chemicals are not necessary and should be kept far away from your four-legged family. 
  • If you come across an issue with these pests, it’s best to act quickly. Find the culprit, remove it from your home, inspect the surrounding area, and then clean every inch of the space. For more information and control methods on pantry moths, click here.

    Oh no! I’m sorry to hear that, it sounds terribly frustrating. You could try moving them into clean, sealable containers and placing the food in a freezer for about a week – the moths wouldn’t be able to survive the cold and the food wouldn’t be damaged. Make sure to keep Stay Away Moths in the adjacent areas of your home so the moths don’t move in to stay.

    Just opened a new 24lb bag of wellness core grain free dog food and it’s full of webs. I’ve been reading about moth infestations but the webs have dead bugs in them like you see with spiders. Do moths catch bugs to eat them? And how did these bugs get in the bag to get caught in the webs?

    We have been having the worst trouble with our dogs lately. They have been getting sick non stop. Throwing up. Pooping blood. Itching like crazy. Breaking out on their bellies and feet/legs.

    I’m 37 and I have always owned dogs. Child to adult. I have never had issues like I have had with the 4 dogs I have now. I have to give them all allergy meds daily. One of them gets so broken out we had to give her antibiotics to help and she still scratches and chews non stop. We have been changing food, changing laundry detergent and dryer sheets. You name it we have changed it. I do know it could be grass or something outside but this is somewhat new. She wasn’t like this when we first adopted her. It’s like out of nowhere she has gotten allergic to something.

    We were feeding them Rachel Ray grain free but they all started puking constantly then the dog with the bad allergies started pooping blood and one of my small Chihuahuas did too so we had to switch them all. We have not been able to find a food that doesn’t have any issues. Has the expectations of the pet food companies gone down?

    During all this we have also found out that grain free could cause heart issues. Our basset can’t have grain so what do I do…

    Any suggestions would be great. Sorry that is so long. It’s been a very frustrating time lately with all the issues with the dogs and their food.

    high end foods have this issue too. Blue, etc. Weird, but I wonder if the companies don’t care, because it means they sell more food, because we paranoid pet parents through out and begin again. I will begin freezing the food in ZIP locks the minute I buy it. No other remedy.
