Guys, I had tried everything and the reason I’m leaving this review is so that no one else goes through the trouble I went through. I did disinfection, nothing... I bought expensive gels from agricultural supply stores, total 138, and nothing. Every time I also did kitchen cleaning... and these German cockroaches... undeterred... I even found them inside the freezer, if you can believe it. Guys, thank you very much, from the first two hours there was a result... well done... and very good price too... I will buy again

Very good and relatively economical compared to others, already from the second day the first corpses appeared haha

Compared to Teza, the corresponding gel in a tube does not do the same job.
Even though they have the same active ingredient.
The problem is that it does not attract them as much as Teza does.

It was the only one that in 15 days I saw had control over the German cockroach.
I recommend it to those who have a problem with cockroaches.

It is very effective! In the afternoon I put it in two or three spots and in the morning I found 7 dead cockroaches!

Returning from vacation, I saw a medium/small-sized cockroach and 3-4 small ones in the sink. After searching, I found out that they are "brown cockroaches". Their nest must be somewhere in the dishwasher, which is built into the lower cabinets. I put a few drops in the adjacent cabinet, which connects to the dishwasher, and in the morning, I found about 15 small ones dead next to the insecticide. They didn't even have a chance to take a step. I also saw a normal-sized one hiding (before I put the insecticide), hoping it will clean itself and all the ones I can't see. Edit: on the second morning, I found 3 adult cockroaches dead, so it works perfectly.
