Of the many types of pantry pests that can invade stored food products, perhaps there is none more common than the Flour Moth.

Known originally as the Mediterranean flour moth, this pesky pantry pest is also called the Indian flour moth, mill moth, pantry moth, or simply flour moth.

The flour moth first made its way to the United States in 1889 via trading ships and is found basically in every part of the world. Despite the name indicating that the Flour Moth has originated from the Mediterranean region, it is believed to have come from somewhere in Central America.

No matter what region of the world it is originally from, the Flour Moth can be found in your cereal, oatmeal, or other flour and grain-based foods.

Most of the damage of Flour Moths are done in their larvae stage. Once the eggs hatch, the Flour Moth larvae have a large appetite and will devour whatever is around them. In industrial settings and households, large infestations of Flour moths can cost a lot of money in food damage.

If you have an infestation of flour moths, there is a way to put an end to their invasion. In this DIY treatment guide below, we will show you just how to get rid of Flour Moth with our helpful advice and professional-grade products which deliver satisfying results.


Before you can begin a treatment program you need to make sure you're dealing with a Flour Moth. Misidentification can lead to using the wrong treatment methods, which can be a waste of your time and money. Here are some of the common characteristics that set Flour Moths apart from other pantry pests.

  • Adult male flour moths are about 0.25 to half an inch long and are usually colored a pale-looking gray.

Inspection is crucial for control. Before you can treat you need to know the areas that Flour Moths are infesting. During the inspection, you will focus on finding "hotspots" where the infestation began.

Where To Inspect

Check in the areas where food goods are stored. Check in the kitchen and garage. Inspect in pantries, cabinets, and shelves. Search the packaging of food goods like grains, cereals, flour, starches, pasta, spices, herbs, pet food, etc.

What To Look For

You're looking for the food item where the infestation began, or signs of Flour moth activity. This includes looking inside food packaging for larvae, adults, skin shells, weird odors and webbing. You may also locate pupae shells on shelves or other parts of the home. If you find any packages where Moths are larvae are found crawling inside this is where you will apply the treatment.


Once you have confirmed Flour Moth activity it is time to begin treatment. Remember to read all product labels and follow the application instructions on these labels, and stay safe by wearing personal protective equipment (PPE).

To get rid of Flour Moths, you will need to perform a preliminary cleanup of your pantry to locate and removed infested products. Afterward, you can treat with three products: Pyrid, Novacide, and Pro-Pest Pantry Traps.

Step 1 - Preliminary Cleanup

Before you can apply the treatment you need to clean the areas where food goods are stored. in this step, you will throw away every single food good in your pantry, and you will also clean the pantries. For this, you will need a vacuum and caulk.

Begin by throwing away every single food good in your cabinet, shelves, or pantry. This may sound excessive, but if you've found one infested package, odds are there are flour moths in your other packaged food. In order to play it safe, it is best to throw away all the food goods.

Once the foods are tossed, take a vacuum and clean the corners, sides, tops, bottoms of the cabinets, shelves, and pantries where the food goods are stored. Use a toothpick to clean the pegs where the screws go, these areas many times will harbor eggs.

Next, take a cloth soaked in soapy water and clean the insides of your cabinets, shelves, and pantries. Finally, use caulking to seal off and close off cracks and crevices, which will prevent the infestation from spreading around your home.

Step 2 - Treat Cracks and Crevices with Pyrid Aerosol

Pyrid application in pantry crack

Pyrid Aerosol is a synthetic pyrethroid insecticide that is used as a flushing agent and is effective as a crack and crevice treatment inside pantries. Flour Moths are known to crawl inside small spaces and lay eggs, so applying this will flush them out and kills them with contact.

Pyrid comes with a crack-and-crevice applicator to allow the product to more precisely treat your cracks and crevices. To use, remove the white applicator from the top of the can and replace it with the red straw tip applicator.

Shake the can and then spray along the length of crack and crevices of your pantry shelving in quick bursts usually at about 1 second of spray per foot. Pyrid will flush pests out of these areas. It will not leave behind a residual but will provide an immediate knockdown after flushing invading Flour Moths out.

Step 3 - Apply Novacide Aerosol

novacide treatment for Flour Moths

Novacide is a dual-action insecticide in that it kills adult Flour Moths and also comes with an IGR (or Insect Growth Regulator) that will prevent the undeveloped stages of Flour Moths (eggs, pupa, larvae) from turning into adults. The best part about Novacide is its residual effect as it can remain effective for up to 7 months so you don't have to apply often.

Novacide Aerosol comes ready to use in an aerosol spray can. Apply the product as a spot treatment. Apply 1 to 2 inches separated by a couple of inches. Spray the back of shelves along cracks and crevices in short, quick bursts so that a fine mist is applied.  Next, spray along the baseboards and flooring of your pantry, kitchen, carpeting and the baseboards of your areas adjacent to your kitchen in a downward sweeping motion.

Do not let people or pets enter areas treated until 2 to 4 hours have passed. 

Step 4 -  Pro Pest Pantry Moth and Beetle Trap

Pro-Pest Traps

Finally, you should monitor Flour Moth activity and capture remaining stragglers with The Pro Pest Pantry Moth and Beetle Trap. This trap is a ready to use, pesticide-free trap that uses a pheromone scented glue board to lure and capture Flour Moths.

To use, simply peel off the protective paper from the pre-baited glue and fold the trap into a tent shape. Place the trap on shelving where it will not get smashed and is out of the reach of children and pets. 

The trap’s pheromone bait will attract Flour Moths to the trap where they will get stuck in the glue. This is an effective, low effort tool that will last between 60 and 90 days. One trap will cover around 300 square feet.


Once you have successfully treated your pantry and have removed the Flour Moth infestation. You want to make sure you don't have a future problem. Here are some preventative measures we suggest taking to make the likelihood of a future Flour Moth invasion low.

  • Start by checking every food package before you buy it. Many times, holes or punctured bags are an indication that the package is infested.
  • Get in the habit of storing all your food goods inside plastic containers. This will make it harder for Flour Moths to enter the packaging, and might even isolate an already infested item and prevent an infestation from spreading.
  • Reduce pantry clutter by buying a week's worth of food goods and do not let food stay stored for months on end undisturbed which can open the possibility of an infestation.
  • Finally, use Pro-Pest Pantry Traps throughout the year to keep Flour Moths from infesting your food goods.
