First of all, we need to know the living habits of cockroaches and know how to cut into the environment where cockroaches live, so as to destroy them. Cockroaches usually only come out for food at night, and they can find their hiding place by placing some sticky mousetraps or using flashlights. Once the cockroach's habitat is found, it is necessary to do a good job of cleaning up, remove all garbage and food residues, and reduce the food source of cockroaches.
Secondly, we can use some physical means, such as covering the sewer to prevent cockroaches from entering. You can also use some chemicals, but choose non-toxic or low-toxic pesticides to avoid harm to the human body. At the same time, we should pay attention to the safety measures when spraying pesticides, such as wearing masks and gloves.
Finally, it is necessary to adhere to health habits for a long time, do a good job of cleaning regularly, and keep the bathroom dry and clean. When cleaning the bathroom, be sure to clean up all the garbage and food residues to avoid providing living conditions for cockroaches. If we can stick to these measures for a long time, we can completely remove cockroaches from the toilet sewer and maintain a hygienic environment.
