Yes, the cockroach's eating habit is high in sugar and oil. I like to eat greasy and sweet food, but the cockroach has a very good sense of smell. It knows the way. For example, after eating, climb out along the bottle mouth. Then how can you invite a cockroach into the urn and not come out?
What you said is a little close to uncle Cao, a little similar, but different. How did Uncle Cao catch cockroaches with this mineral water bottle?
This prison is the secret weapon in Uncle Cao's cockroach bottle. With it, cockroaches can only come in and out. What's going on here?
First, this 70-mm-long and 80-mm-wide iron screen window is folded in half along two diagonal lines, and then shrunk into a cone shape.
The metal wire ring, which is formed by winding this metal wire, is pressed to the end to play a role in shaping and strengthening.
The wire funnel is ready, but how can it be installed on the bottle?
Use this tool to make this bottle cap stick vertically on the inner wall of the bottle cap. Just take a heavy object and knock it, evenly open a big hole and cut a circle vertically. The small funnel we made lies directly in the bottle cap and lies to the end. Using the source of chopsticks, adjust the holes for them, and the finished product we made will be screwed on the bottle cap.
It is necessary to change bait frequently to trap and kill cockroaches, but this wire funnel on the bottle mouth is too inconvenient to change bait. Cockroach is the common name of some indoor living species in Lianzhong. It eats almost everything and has no strict choice of food, so it is very easy to survive. It is precisely because of this that it was verified by Uncle Cao that any food residue can be put into the bottle. It can be said that this cockroach bottle didn't cost a penny more. Experiments show that cockroaches can quickly develop resistance to pesticides, so although pesticides take effect quickly, the physical cockroach catching method with bait like Uncle Cao is worth popularizing.
It turns out that there are too many cockroaches in our unit to put anything in the toolbox drawer.
So, according to the principle that flies can only get in, Uncle Cao made the first cockroach bottle from a tea barrel and used it in the company until ten years ago, when Uncle Cao met a cockroach at home.
As soon as I entered the kitchen, it was all over the chopping board and table. It crawls everywhere. It is very hard. After TV, I heard that this cockroach spread more than 40 diseases, which made me work harder. Then I told my family what to do with this cockroach. How can I eliminate it?
So Uncle Cao took home the magic weapon that he had used in the company for 13 years.
