Attention, everyone in Shenzhen. Someone came to the door and said it was not credible to kill cockroaches.

There is no such thing as a free lunch. Everyone who provides this kind of door-to-door service must be careful to prevent being cheated. In fact, the medicine they sell is very cheap, like 10 gram 49.8 yuan. I bought a 30-gram gold bait for killing cockroaches directly from the manufacturer, and it only costs 4 1 yuan, and the effect is also very good. If there is a need to kill cockroaches, I should not be cheated by door-to-door service.
