How effective are cedar blocks / hangers for moths?? Worth the investment? And if so, where would be the best place to buy them and are they all the same?

They work by hiding the smell of the wool/cashmere that moths are naturally attracted to to lay their eggs (they would normally lay eggs on an actual animal, not a sweater). The eggs then hatch and the larvae eat at the fibers. They do not repel moths and moths are not repulsed by the smell of cedar. If the moth by chance finds your sweaters, then they'll find it an lay their eggs. I guess the idea is to reduce the chances of finding the smell of animal fibers.
AH! useful thanks.. do you know if they are attracted to colgone/perfume like smells?
That is an interesting explanation of cedar, but my understanding is that there is no real evidence as to why it works in keeping moths out, but it does. What it does not do is kill the eggs if they are already there. For what it's worth, my pest control guy told me that cedar is effective.
I place cedar blocks in satchels and just hang them with my clothes. Some garment bags also have a small pocket inside for cedar blocks, which is great for making sure moths don't eat your suits.
I heard they could stain as well, wonder why that is..
Some of these poorly made products are artificially stained to produce a nice color. I bought a few and they stained especially when the shirt was still damp. I wouldn't use cedar hangers. Just put cedar blocks.
mothballs are toxic if exposure is long enough. It is in essence an artificial chemical. What is wrong with lavender?
