The average time before a lice infestation is discovered is about 4 to 6 weeks. The severity of the signs and symptoms will depend greatly on the size and length of the infestation.

  • Red Rash at the Nape of the Neck
  • Sleepiness
  • Scalp Damage

A head lice infestation will vary in size depending on the amount of the initial adult louse transfer. Once on a new host, the adult louse will continue the cycle with a new generation of nits. From nit to deceased adult louse, the lifespan is 30-33 days.

Lice leave behind a scent created from the saliva and urine that is embedded into the hair shaft. This scent actually attracts a new infestation that lasts up to 30 days. The use of repellent products help mask the scent, thus, lowering the chances of receiving another lice infestation.
