We often calls from families in Grand Rapids and Lansing area asking how it is possible that their children have head lice in the middle of the winter. Parents ask, "doesn't the cold weather kill head lice?" The answer is no. Once there is a case in a classroom or a family or among friends, the lice will move from head to head, regardless of the weather. To survive head lice need human blood and the temperature of the head. Lice feed three times a day, and as long as they have a food source they will survive. Head lice are incredibly hearty which is why they have been around for thousands of years. We do tend to see a higher incidence of head lice during the warm weather months, not because of the air temperature, but because children are outside playing. This close contact allows for head to head contact and the transmission of head lice. Cold weather, in and of itself, is irrelevant to head lice. Even in the middle of a cold winter, LiceDoctors recommends that you do regular lice checks on your children. Bring them to a bright light and check to see if there are translucent eggs stuck to the hair. Of course excessive scratching is a telltale sign, but not everybody who has head lice manifests signs of itchiness. If you find head lice, give us a call today and we will get rid of your head lice problem. Call LiceDoctors in the Lansing and Grand Rapids area at 616-965-2591.
