Also, the dawn dish soap allows the waxy cuticle of the fleas to absorb water and thus its respiratory system leading to the drowning of the bug.

Step 2: Breaks Waxy Layer of the Fleas’ Respiratory System

Drowning fleas under normal circumstances is difficult. This is mainly because the respiratory system of fleas has a waxy layer that prevents water from entering. Further, the wax is also in the trachea and hence bars water from moving into the respiratory systems.

Application of dawn dish soap breaks the wax layer and thus allows entry of water into the fleas’ respiratory system. Therefore, the fleas suffocate as the water replaces the air and the dish soap could make suds to obstruct the fleas’ spiracles.
