People have tried many ways to kill head lice including attempted suffocation with various oils like mayonnaise and petroleum oil. Lice are remarkably well equipped to combat this treatment. They simply take a deep breathe and batten down the hatches by closing their spiracles, the entry point to their breathing system. In the meantime they have become resistant to the many drug treatments that have been thrown at them.
But now a new way to suffocate them has been developed and it's 92% effective. Even better it's non-toxic. By using benzyl alcohol lotion stuns the spiracles and prevents them from closing. This allows mineral oil and other ingredients to enter their breathing apparatus and kill them.
