The reason I got it was the cockroaches.
I made a dough from this powder, flour, milk, and sugar and placed small pieces in various spots around my house (mainly shelves and corners where I often found cockroaches).
For 2 weeks the cockroaches continued as usual and then one day they disappeared. I haven't seen a cockroach in my house for a month during August, I recommend it

It's really useless. I always had excellent results with ants but with this, nothing happens. Ants eat it and multiply

We couldn't get rid of the drain flies no matter what medication we used. We put the powder in all the drains in the house and the problem stopped the very next day.

I was swayed by the positive comments regarding the ants' combat...
I have been trying for a week with various recipes I found (the product along with sugar and a little water)...
No result...
Money wasted and the ants well-fed..

I used it in a recipe - a home remedy for ants that I found on YouTube. It is the only one that brought results, it eliminated the ants from the kitchen and greatly reduced their population on the balconies without affecting the plants. Now I rarely see ants walking around, and as soon as I spot one, I make the recipe again in a bottle and leave it in the place where I saw it, and I don't worry anymore.

The shoes and feet don't smell.
In fabric shoes, a little bit comes through, but it cleans with a damp cloth.
