TL;DR: Place moth traps in open areas near the source of moth activity, with enough space for air to move around the pheromone lure. Do not hide traps behind pantry items, crowd them between garments or place them inside sealed containers. Use pantry moth traps near dry-food storage and clothing moth traps near wool and other animal-based fibers.
Pantry moths and clothing moths behave differently, so correct placement begins with identifying which moth you have.
Both pantry and clothing moth traps use pheromones infused into the glue to attract adult male moths. The scent moves through the surrounding air rather than along one straight path, which is why placement matters.
Where should I place pantry moth traps?
Pantry moths are stronger fliers than clothing moths and may move between food-storage areas.
Think of your kitchen as a scent map. Position the traps near the areas showing the most activity, with enough open space around each trap for moths to enter.
To achieve this, start with three traps in a wide triangle:
- Place one inside the main pantry near the dry goods showing the most activity.
- Place one on the inside of the pantry door or on an open shelf.
- Place one near another dry-food source, such as pet food, birdseed or a separate cabinet.
The triangular setup helps cover several possible activity points rather than concentrating every trap in one part of the kitchen.
Tip: A trap on the inside of the pantry door can help carry the pheromone beyond the pantry and into the nearby kitchen each time the door opens and closes.
Use different heights when moths are active in more than one part of the pantry. For example, place one trap on a higher shelf and another near food stored closer to the floor.
Keep traps away from lavender sachets, cedar products, essential oil diffusers and strongly scented cleaners. These scents may interfere with the lure.
Pantry moth traps capture adult males, so they should be paired with inspection, food disposal and cleaning. Trap placement works best as part of a full removal plan.
For dry-food storage areas, Pantry Moth Traps provide a species-specific option for pantry moth control.
Where should I place clothing moth traps?
Set at least two traps:
- Place one trap high on a curtain rod, closet rod or upper shelf.
- Place one trap low on a lower shelf or on the floor.
Keep the traps no more than 22 feet apart and leave enough open space around each one for moths to enter.
Choose dark, quiet and low-traffic areas where activity or fabric damage has already been found. Avoid wedging traps between tightly packed garments or placing a fan directly beside them.
Confirming which moth you have helps ensure you are using the correct trap.
For closets, wardrobes and fabric-storage areas, Clothing Moth Traps are designed to attract adult male clothing moths.

Why isn't my trap catching anything?
If a trap remains empty after placement, start with the setup.
Did you remove the protective sheet?
The protective sheet covers the adhesive and pheromone. Remove it before placing the trap, taking care not to touch the exposed glue.
Are you using the correct trap?
Pantry moth traps are designed for food moths, including Indian meal moths. Clothing moth traps are designed for webbing and casemaking clothing moths.
Use the location and damage as your first clues. Moths found around dry goods need a pantry moth trap. Moths found near wool, fur, silk, feathers, felt or leather need a clothing moth trap.
For a closer comparison of their appearance, behavior and food sources, see pantry moths vs. clothing moths.
Are you expecting the trap to catch every moth?
Pheromone traps attract adult male moths. They do not catch adult females, eggs, larvae or pupae.
You may still see moth activity while other stages of the lifecycle remain present. An empty trap may also mean that adult males have not yet reached it.
How long do moth traps take to work?
Pantry moth traps may need up to 10 days before adult males begin finding the pheromone attractant. Results can vary with airflow, placement, time of year and the stage of the moth lifecycle.
Clothing moth traps can take longer because closets often have tighter airflow and clothing moths are weak, erratic fliers. Give them at least 25 days before deciding whether the traps are working.
The time needed to catch moths is different from the time needed to resolve the full infestation. Eggs, larvae, pupae and adult females may still be present while the traps are catching males. For the broader timeline, read how long it takes to get rid of pantry moths.
When should you move a moth trap?
You can move a trap when the current location is not producing catches or when moth activity points to a better spot.
Give the trap a few days in its initial location before making a small adjustment. An empty trap does not always mean the area is clear. It may simply be too far from the strongest activity.
Relocation may help when:
- Moths repeatedly appear near another shelf, cabinet or closet corner
- You find damaged food packaging in another storage area
- You discover fabric damage away from the current trap
- One trap catches moths while another remains empty
Move the trap a few feet toward the stronger signs of activity rather than relocating it to a completely different room.
For pantry moth traps, test another point in the triangle. For clothing moth traps, preserve the high-and-low arrangement while adjusting the location.
When should you replace a moth trap?
Once the protective sheet is removed, pantry and clothing moth traps remain effective for up to three months.
After three months, the strength of the pheromone begins to wane. Replace the trap sooner only if it becomes full.
Keep unopened traps sealed until needed. Dr. Killigan's pantry and clothing moth traps are designed to maintain potency for up to three years from the date of manufacture, which is printed on the package.
Tip: Even after catches decline, keeping a fresh trap near the original activity area can help you monitor for adult males emerging from a later hatch.
