Advion Cockroach bait works 11 month update

Update Its Sept 2022 and still no cockroaches
I'm South African bought it on uBuy.com actually there was a guy selling this in South Africa just google pest store at the time Ubuy was cheaper,please read and google instructions and videos do your research as well before purchasing and using.i think I applied the bait twice in space of a month or so but there's a lot in box so one box should be enough.
