I put it on when I leave the house in the village and when I return after a reasonable amount of time,,,, whatever is there is dead!!!scorpions, centipedes, ants, flies and generally any little creature or insect that enters the house!!!

I bought it to deal with food moths. I tried everything available on the market but none of them eliminated them completely. This particular insecticide is the strongest I have tried but it does not kill the eggs and larvae. The result is that a few days after application I find new moths. The unpleasant thing is that I cannot repeat the spraying before 6 months have passed (as stated on the bottle). The pleasant thing is that for a month now no ants or cockroaches have appeared at all. So it doesn't work for moths but for cockroaches and ants I recommend it

K-Othrine (the Original by German Bayer) and Delta-methrin (the generic by Greek Farma-Chem) and Killmethrin (the generic by Indian Sharda) contain the active insecticide substance Deltamethrin in a concentration of 2.5% by weight (sold as a powder that dissolves in water). In my opinion, there is no better insecticide (flies, mosquitoes, cockroaches, etc.) that is as safe for humans. The only drawback is that it leaves a white powder on surfaces after spraying. PERFECT FOR EXTERNAL USE. Alternatively, use Solfac (by Bayer) which can even be sprayed on the mattress you sleep on.
