8 ways to outsmart pantry moths: Eggs, larvae and future prevention

Updated on January 17th, 2025

Setting up a trap might seem like a quick fix to tackle pantry bugs, but without addressing the root causes and every stage of their lifecycle, the issue will persist—and likely grow. Pantry bugs—such as pantry moths—can turn your well-stocked pantry into a contamination zone, infesting food at any stage of their lifecycle: eggs, larvae, pupae or adults.

This guide doesn’t stop at traps—it explores eight proven strategies to get rid of pantry bugs—specifically the pantry moth—and prevent their return, ensuring your pantry remains pest-free. If you’re ready to outsmart these pesky invaders for good, keep reading.

1. Know your enemy: Ensure it’s a pantry moth

Before tackling a pantry bug infestation, confirm whether you’re dealing with pantry moths or another type of pantry pest. For example, do the moths fly in zigzag patterns or is their flight weak and indirect? Different moths require different management strategies, and pantry moth traps are specifically designed to catch various types of pantry moths - of which there are 10. 

Tip: Trying a pantry moth trap can be a helpful diagnostic step if you're unsure whether you have pantry moths. The pheromones in the traps are designed to attract pantry moths—if you have them, they will come; if not, the trap will remain empty.

2. Early warning signs: How to detect a pantry bug infestation 

Early detection of a pantry moth infestation is crucial. Key signs include:

• Webbing and clumping: Look for strings of webbing inside or at the corners of packages, which can cause clumps in flour or strings of oats. 
• Unpleasant odors: Unusual or unpleasant odors from food containers or grains often indicate an infestation.
• Adult moths: Adult pantry moths may fly around the house in a direct, steady or erratic zig-zag pattern, especially near food sources.
• Larvae: Cream-colored larvae resembling maggots may be found in various locations. They are capable of chewing through paper and plastic. 
• Moth feces: Small black dots, which are fecal droppings from the moths, can be found near infested items.

3. End the infestation: Tackle pantry moths at every stage

This pantry bug undergoes four distinct life stages. The larval stage is particularly destructive as it feeds on stored foods, leading to spoilage and contamination. 

Each phase requires a different management strategy. Addressing only one stage can allow others to continue and proliferate, potentially leading to simultaneous infestations in other parts of your home. 

Note: Eggs laid by trapped adult moths today can hatch within 20–30 days. Continuous monitoring and management are crucial to breaking the cycle. Even if adult sightings decrease, emerging larvae can sustain the infestation. Eliminating all stages can take three weeks to six months, depending on the infestation's severity and kitchen cleanliness.

4. What these pantry bugs eat—and where they lay eggs

These pantry bugs—specifically the pantry moth larvae—thrive by consuming a variety of dry goods commonly found in your pantry. The adult pantry moths typically lay their eggs directly on food sources, where the hatching larvae have immediate access to food and prepare for the next stage of their life cycle. 

When ready to pupate, these larvae often migrate to secluded spots such as wall-ceiling junctions, door hinges, backs of door knobs and underneath shelves. Surprisingly, you may also find larvae tucked into the edges of cans or spice jars or even in unopened packages and sealed containers, demonstrating their ability to infiltrate seemingly secure areas.

5. Smart trapping: How to use pheromones to stop pantry moths

Setting up pheromone traps is a proven way to combat pantry moths. Dr. Killigan's Pantry Moth Traps use specific pheromones to attract and capture adult male moths, preventing them from mating. 

Placement is crucial: For detailed strategies on optimal trap placement, read our comprehensive guide: 

• Where do I place moth traps to get rid of moths? 

Regular replacement of these traps is also essential to maintain their effectiveness. 

Tip: Although pheromone traps effectively catch male moths, they do not capture female moths, who may continue to lay eggs. To manage female moths and larvae, hand-kill them or use Dr. Killigan's Six Feet Under Plant-Powered Insect Spray.

6. Monitor and manage: Take control of pantry moth infestations

Effectively manage your infestation by monitoring your pheromone traps daily and note any increase or decrease in moth capture. A sudden increase typically signals an active, unidentified source of infestation needing immediate attention. Conversely, a consistent decrease—over a week or two—is a positive sign that you are eliminating the infestation at its source.

7. Clean, clean, clean 

Effective cleaning is key to eliminating these pantry bugs and protecting against future infestations. Follow these steps:

• Empty your pantry: Remove everything from your cupboards and food storage areas, including cans and glass jars.
• Vacuum thoroughly: Use a vacuum with a crevice attachment to focus on shelves, baseboards and corners to remove moth eggs and larvae. Pay special attention to the corners, undersides, shelf brackets and mounting hardware. Ensure you change out the vacuum bag or empty the canister outdoors immediately afterward.
• Wash with water and vinegar: Clean all surfaces with a 50/50 mixture of distilled white vinegar and warm water to remove sticky residues and disinfect. This simple solution helps break down any residues that might attract moths.
• Inspect and replace shelf liners: Remove and replace any torn or peeling shelf liners to eliminate hidden moth eggs.
• Apply Six Feet Under Plant-Powered Insect Spray: Spray this non-toxic solution to kill any remaining larvae and eggs. Our spray acts on contact and is powerful enough to target even the smallest moth eggs, ensuring complete eradication.

Tip: Delay restocking your pantry to ensure all moth activity has ceased and cleaning efforts are effective.

Tip: For added protection, sprinkle Dust to Dust Plant-Powered Insect Powder around the edges and corners of your pantry shelves. This helps capture any larvae or eggs hidden in hard-to-reach areas.

8. Stay protected: Proactive steps to prevent pantry moths

To safeguard the quality and safety of your food, implement these proactive measures:

• Freeze suspected items: Freeze any food items that seem intact but raise suspicions at 0°F for four days to eradicate any hidden eggs. For open items without visible signs of infestation like clumps, webbing, or black dots, consider a quick external inspection. If unsure, securely bag and freeze the item as a precaution.
• Have secure storage: Immediately store all pantry items in sealed glass or metal containers upon bringing them home. This practice ensures that even if a product is infested, the larvae cannot escape and contaminate other items.
• Refrigerate spices: Store small bags of spices in the refrigerator or freezer to prevent infestation.
• Store pet food properly: Keep pet foods and birdseed in covered metal containers away from the pantry, preferably in a laundry room, garage or outside shed.
• Be mindful of edible decorations: Opt for twig or evergreen wreaths over seed-and-fruit wreaths and hang them outside to avoid attracting moths indoors.
• Use Dr. Killigan's Pantry Moth Traps: Monitor for the presence of pantry moths and aid in preventing future infestations by using these traps. 
• Implement regular checks and cleaning: Preempt conditions that foster moth infestations. Be vigilant about inspecting new groceries outside before bringing them into your home.
