Best Smelling Cedar Blocks for Your Closet: American Red Cedar vs. Everything Else

By Harrison Lowell, Dr. Killigan's

Open a drawer of cedar sachets you bought a year ago and smell nothing — that's the normal life cycle of most cedar products on the market, because almost none of them tell you what kind of cedar is inside or where it came from. Dr. Killigan's Cedar Chips Canister uses American natural red cedar, harvested locally, specifically because that sourcing produces a distinct, notably strong scent that holds up longer than cedar that's been sitting in overseas shipping and warehouse stock before it reaches a shelf.

What actually makes cedar smell like cedar

Almost every competitor in this category — Cedar Space, HOUNDSBAY, ACMETOP, the generic multi-packs that dominate Amazon search results — describes its product as "natural aromatic cedar" without naming a species or origin. That's not necessarily dishonest, but it means the scent quality and how long it lasts is essentially unverifiable from the listing alone. Cedar's characteristic smell comes from aromatic oils in the wood, and how strong and long-lasting that scent is depends heavily on the species and how fresh the wood is when it reaches you — cedar that's spent months in an overseas shipping container and a warehouse has had more time for those oils to fade before it ever reaches your closet.

Dr. Killigan's names both the species (American red cedar) and the sourcing (harvested locally) specifically because that combination is what produces the stronger, longer-lasting scent — and it's genuinely uncontested ground in this category, since almost nobody else makes that claim explicitly.

One real toxic outlier worth naming: Enoz's "cedar scented" moth cakes aren't cedar at all — they're paradichlorobenzene, an EPA-registered chemical fumigant scented to smell like cedar.

The honest trade-off

Generic loose cedar sachets and blocks are dramatically cheaper per unit — several competitors sell 16 to 56 pieces for less than half of what Dr. Killigan's 8-tin canister costs. If price-per-unit is the only variable, those are legitimate options, though the research turned up no equivalent sourcing or species claim behind any of them. The tin format also protects the chips differently than an open sachet does, which matters for how long the scent holds indoors.

Why trust Dr. Killigan's: Dr. Killigan's is the original natural pest control company, and every product — including this one — is developed with practicing biologists and entomologists and evaluated repeatedly in Dr. Killigan's own labs. "Natural" isn't the finish line. Proven is.

FAQ

What's the best smelling cedar for a closet?

American red cedar, specifically fresh and locally sourced rather than imported and warehouse-stored, produces the strongest and longest-lasting aromatic scent.

Why did my cedar blocks stop smelling like anything?

Cedar's scent comes from aromatic oils that fade with time, heat, and humidity — how fresh the wood was when harvested and how long it sat before reaching you both affect how quickly that happens.

Is "cedar scented" the same as real cedar?

Not always — some products marketed as cedar-scented, including certain mothball products, are actually synthetic fumigants scented to smell like cedar rather than made from it.

Does the tin format matter?

Sealed tins protect the chips from air exposure between uses more than a fully open sachet does, which can help preserve scent longer.

Bottom line

If price-per-unit is all that matters, generic sachets are cheaper. If you want cedar that actually smells like cedar — and keeps smelling like it — sourcing and freshness are the variables that matter, and this is one of the only products in the category that discloses either.
