Do Cedar Blocks Really Repel Moths? | Specter Pest Control
Cedar blocks, chips, and hangers are a classic choice for keeping moths away from your clothes and pantry items. But do they actually work—or is it mostly a home remedy myth? At Specter Pest Control, we help homeowners understand what works, what doesn’t, and how to protect your home from moth infestations effectively.
How Cedar Blocks Are Supposed to Work
Cedar contains natural oils that release a distinctive scent. The theory is that this aroma masks the smell of natural fibers like wool, silk, and cashmere, making your wardrobe less appealing to clothes moths.
Homeowners often use cedar blocks or hangers in closets and storage bins, hoping the fragrance acts as a chemical-free deterrent.
The Reality About Cedar Blocks
While cedar does have moth-repelling properties, its effectiveness is limited:
-
The scent fades over time: Once the fragrance diminishes, so does its moth-deterring power. You can refresh the aroma by sanding or rubbing the wood.
-
Cedar doesn’t kill moths: If larvae or eggs are already present, cedar blocks won’t eliminate the problem.
-
Effectiveness varies: Factors like humidity, air circulation, and the type of cedar used (Eastern vs. Western Red Cedar) affect results.
In short, cedar can be part of a prevention strategy but isn’t a standalone solution.
Practical Tips for Using Cedar at Home
If you want to use cedar blocks, consider these strategies to maximize effectiveness:
-
Keep cedar fresh: Sand or rub blocks regularly to release oils.
-
Use airtight storage: Combine cedar with garment bags or sealed containers.
-
Rotate clothing: Avoid leaving items undisturbed for long periods.
-
Inspect regularly: Early detection of holes or larvae can prevent major damage.
Other Natural Moth Prevention Methods
In addition to cedar, homeowners can try:
-
Lavender sachets: Mildly repellent but better combined with other methods.
-
Proper cleaning: Vacuum and clean closets regularly to remove eggs and larvae.
-
Freezing or laundering: Items stored long-term can be frozen or washed to kill eggs.
While these methods help, they are supplemental. For serious or ongoing infestations, professional pest control is the safest and most reliable option.
