Home Remedies Lice Non-Toxic. What is the difference between olive oil, pesticide lice shampoos and combing with a metal nit comb? Olive oil is useful in treating lice because the lice breath through tubules in their shells called spiracles. Olive oil clogs the spiracles depriving the lice of oxygen which smothers them. Pesticide lice shampoos were effective when they were first introduced over ten years ago. Now, however lice have developed resistance to the pesticides in the shampoos, rendering them ineffective. Combing with a good metal nit comb is effective because it can strip the lice eggs (nits) off of the hair shaft. Olive oil and pesticide shampoos do nothing to kill nits.
