Can You Kill a Cockroach With Hot Water?

Can you kill a cockroach with hot liquid? The simple answer is yes. When water reaches 212 degrees Fahrenheit, it becomes a boil and a roach is unable to live in that temperature. A roach’s soft, moist body does not hold enough moisture to withstand boiling water, and this heat will destroy the external cells of the roach.

Cockroaches are attracted to a variety of damp, dark and dirty places. If you find roaches in these places, you may be able to kill them by pouring hot water over the roach’s hiding places. This method will also kill their eggs.

Besides hot water, other methods include Listerine and washing up liquid. A mixture of Listerine and water can kill the roaches in contact with it. The mixture can be sprayed around the house or directly on the cockroach. This method can also be effective in removing the original color of the backpack, as the hot water bleach solution will kill the bugs’ body cells by burning them.

Moreover, a roach’s ability to breathe underwater is an important factor in determining whether it can survive a period of time in a closed plastic bag. Although some roaches can survive up to 40 minutes under water, others cannot survive this long. Moreover, roaches do not have gills, which are essential for filtering water.
