I received this package; it says for ants but doesn't mention anything about cockroaches. I will try it and see how effective it is for cockroaches.

Excellent product! It actually works and my ants didnt come back.
The cons: its a white powder (like soda) and where ever you apply it, it stands out. It would have been perfect if it was another color, like grey or beige.
Would I buy it again, definately yes because I havent found a better alternative.

The product is very good. I was wasting money for so many years on sprays. This one is odorless; you place it wherever you see ants passing by and it does its job. It is also very good for little flies and cockroaches. As soon as the insects come into contact with it, it acts immediately. Leave it there all summer and forget about insects.

It exterminates ants.
The product needs to be reapplied if it is washed away by rain.

Any bug that comes into contact with the powder is exterminated, it helped me get rid of cockroaches and ants.

It is probably effective. My agronomist told me to use it everywhere except the bedroom, even in the kitchen. If you have pets, NO, if they eat it, etc. Anyway, I had called a pest control team, and it didn't work, so I bought the powder as a supplement. I think cleanliness is the key; a friend of mine told me: cockroaches go where there is dirt. Even now, I sporadically find cockroaches, for example in the kitchen sink, I don't know if they come in from the drains, and small dead cockroaches in the storage room, so they have a nest. Don't be stingy, and call a pest control team, cleanliness!! Personally, I sprinkle a new amount every 10 days, sweeping up the old. Pest control at the beginning of summer, they also put the poison in the drains.

It is effective for ants, but it requires quantity and good "spreading" if it is an open space; otherwise, the ants learn and avoid it. If you pour it into holes/crevices where they have made nests, it exterminates them immediately.
