What if there are too many cockroaches in the hotel?

Hotel cockroaches can be killed by making a safe and nontoxic cockroach trap. The specific operation steps are as follows:

Required materials: plastic bottle, paper cutter, clean water, sugar, baking soda.

1. Prepare a plastic bottle first.

2. Use a paper cutter to cut off the two-thirds part near the top of the beverage bottle, and pay attention to cutting the edge flat.

3. Put sugar in a plastic bottle, because cockroaches like sweets, and sugar can attract cockroaches.

4. Pour in baking soda. Baking soda is alkaline. If you eat baking soda, the cockroach's stomach will be destroyed.

5. Insert the top half of the cut bottle cap downward into the plastic bottle. Pay attention to seal the gap at the edge to prevent cockroaches from going out. Put the plastic bottle in the corner of the hotel where cockroaches often haunt.
