Lice infestations can occur at any time of the year, but they tend to be more common during specific seasons due to various factors:

  1. Back-to-School Season: Infestations often spike in late summer and black lice in hair early fall when children return to school. Increased interaction among children in classrooms and extracurricular activities raises the likelihood of lice transmission.

  2. Winter Months: The winter season can also see an increase in lice cases due to more indoor activities, such as family gatherings, where close contact is more likely.

  3. Warm Weather: In some regions, warmer weather may also contribute to higher rates of lice. Outdoor activities during the spring and summer can lead to more opportunities for head-to-head contact among children.

  4. Crowded Environments: Any time of year, crowded environments, such as camps, schools, and daycare centers, can facilitate the spread of lice, particularly among children.


While there may be seasonal patterns, lice infestations are ultimately influenced by behavior and proximity, rather than weather alone. Maintaining preventive measures year-round is important to reduce the risk of infestation.
