1. Material preparation:
30g boric acid, 34g flour, 35g cooked soybean powder, 10g honey, 25mg cypermethrin (low-toxicity pesticide), electronic balance.
2. Material processing:
1. Mix the flour and soybean flour. If possible, add 3g of fish meal, add an appropriate amount of raw oil, and fry until cooked. (referred to as material 1).
2. Then mix the above processed material 1 and boric acid. (referred to as material 2)
3. Use another cup (note: in order), mix cypermethrin and honey evenly, and then pour 40ml of water into the honey. (referred to as material 3)
4. Finally, mix material 3 and material 2 and knead into dough. It is best to wear gloves when mixing the above.
3. Production method:
1. After complete mixing, place it in the oven to dry. In order to shorten the baking time, it is best to flatten the dough and maximize the surface.
The baking time depends on the actual situation, until the water in the dough is completely dried. (Note: When making it at home, you can use a few bricks and temporarily build a firewood baking box outdoors. Do not bake in the kitchen, let alone bake in an oven used for cooking food.)
2. Baking Once dry, crush it, a lab grinder is available. To make it at home, you can wrap the dried dough with newspapers, press a beer bottle on top, press the beer bottle with your hands, and roll it back and forth to crush it.
3. After making the cockroach pesticide powder, put it in a bottle. When using it, you can pour a small amount of powder into the cracks of the wall, or use a small amount of water to make the powder into small balls and place them in places where cockroaches are infested.
