How to Kill Lice on Hats, Helmets & Hard Surfaces

Itchy head lice are transmitted through direct contact or the sharing of personal items such as hats and other headgear. Once a lice infestation occurs, the pests spread rapidly through the host's home, including onto furniture and other hard surfaces. According to the Illinois Department of Public Health, chemical fumigants are not appropriate for treating lice infestations in the home. Lice can be eliminated by laundering items and performing routine cleaning tasks.

  • Washer and dryer
  • Disinfectant cleaning spray
  • Vacuum cleaner
