- Enoz Moth Cake (hang-up cakes and refills): Warning[1]
The airtight rule
Every Enoz label limits use to clean, airtight containers. Dry cleaning bags, garbage bags and any container that lets vapor leak into occupied rooms are off limits.[1]
The label gives a simple check: if you can still smell the product after putting it in a container and sealing it, that container isn't airtight and shouldn't be used.[1]
Other cautions on the label
The cake is combustible, so keep it away from heat and open flame. The label also carries a California notice that it contains a chemical the state lists as causing cancer.[1]
Where it is used
Dry clean, wash or brush clothes and other fabrics before you pack them away. The label says this step applies to every fabric type.[1]
Hang the cake at the top of the container, because the vapors work downward. Keep the container closed for at least 7 days.[1]
Use only polyethylene or polypropylene containers, since the cake can damage some plastics. Don't mix it or use it with other moth-prevention chemicals.[1]
Moths are active all year, so the label says to replenish sealed containers and bags twice a year. The odor fades quickly once stored items are aired out.[1]

Common questions
- Can I just hang a moth cake in my bedroom closet?
- Only if the closet is truly airtight. The label forbids containers that let vapors escape into occupied rooms, and a lingering smell after sealing means the space isn't airtight.[1]
- How many moth cakes do I need?
- One 2 oz cake treats up to 6.25 cubic feet, and one 6 oz cake treats up to 18.8 cubic feet of airtight space.[1]
- What if a child swallows a moth cake?
- Call a poison control center or doctor right away. The label says to have the person drink several glasses of water, and not to induce vomiting.[1]
