Does Alcohol Kill Cockroaches?

If you want to know if alcohol kills cockroaches, the answer is yes. However, it must be applied directly to the roach. Otherwise, the rubbing alcohol will damage the surfaces. Because alcohol is a valuable substance that can cause serious damage to a home, it must be handled properly. Here are some precautions that you should take before using alcohol to kill roaches.

Cockroaches can be attracted to the smell of alcohol. Since alcohol contains high concentrations of sugar, cockroaches are drawn to it. Moreover, alcohol makes cockroaches lose their sense of control, so they end up stuck in a bowl of alcohol. Because of this, they can no longer breathe. Their shells contain spiracles that allow them to get air, but the alcohol prevents their spiracles from opening. As a result, they die from alcohol poisoning.

Another way to kill cockroaches is to mix boric acid with water. The solution will suffocate the roaches by forming a thin film around its body. To make the mixture more effective, shake it thoroughly. However, it should be remembered that boric acid is very toxic. If inhaled, it can cause respiratory problems, dizziness, and nausea. Therefore, it is important to wear safety glasses and to carry a small spray bottle.

Rubbing alcohol is flammable and can easily damage surfaces, including the skin of a roach. So, you should be careful while spraying it around windows and doors. It may not work, as roaches are attracted to smell rubbing alcohol, and so may walk away. Also, alcohol is dangerous if sprayed on the wrong object.
