The EPA gets rather vocal about the chalk...

... and I can see their point about labling and kids. Not much of a concern for retired cruisers.

Wiki on the other hand said it "contains the pesticides deltamethrin and cypermethrin" and "Despite its illegal status, 'Chinese Chalk' is still imported from China and sold in Chinatowns in the United States. Worldwide, the product remains very popular due to its effectiveness in rapidly controlling crawling household insect infestations without fumes, foul smells or sticky toxic residues, and its relatively low overall toxin content compared to other insecticides."

The ingredients seem to be thought relatively safe.

Cypermethrin - Wikipedia, the free encyclopedia

These are used in the US. Thus, it is only the packaging that the USEPA hates, which makes sense. Seems like a good product to me, specifically because application can be so well controlled.
This looks like some good stuff. I understand why the EPA would not like it, first they did not get there money to approve it, but more importantly it does look like a child would think it was chalk, and we all knew a kid in grade school that ate both chalk and paste (what ever happened to him?) and that could easily be deadly. So if you have children around, especially if you frequently have guests with children, I think it would be safe to say do not use or have around the boat! But if you are an adult and understand to not eat chalk, especially this chalk then you should be OK. I like the way it looks like it can be used in a very controlled fashion. But don't like that it looks like a child's toy.

To my idea looks like a use with caution product.
