Does lysol in a can kill the fungus that causes athlete's foot on surfaces like carpets? and is it safe to spray it in my shoes for treatment and prevention?

There are better options than spraying lysol in your shoes. You may try antifungal foot powder, available in drugstores, without a prescription.

Surprisingly, the manufacturer's website says it kills "Trichophyton mentagrophytes (Athlete's Foot Fungus)". I have not personally recommended this to patients. It would not hurt to try. However, athlete's foot consists of itchiness, scales, and skin maceration. Terbinafine/Lamisil is preferred. See Link: https://www.lysol.com/products/disinfectant-spray/lysol-disinfectant-spray.
