Can Lice Survive In The Cold? [6 ANSWERS FOUND]

What happens when they fall off the head? Lice do not like to leave the head, especially when the temperature off the head is less inviting. However, in the very rare case of a louse falling off the human head in the cold, the principle regarding how long lice live applies. Off the human head, live bugs can only survive for one day. It is safe to say that when it comes to being outside, the chances of that louse surviving by finding a new human host is a non-reality. For a louse to make it to the human head, the head needs to make direct contact with that bug….and what are the realistic chances of that happening?

Lice are small insects, about the size of a sesame seed, that feeds off your scalp. Because they can’t jump or fly, they rely on head-to-head contact to spread from one person to another. Unfortunately, any kids you have may be more prone to catching head lice than most adults since kids come into contact a lot in the course of playing sports or just playing in general. They may spread more slowly in the winter since your kids are more likely to be wearing a hat and not playing sports as much and therefore, creating less opportunity to catch them. [3]

The researchers at cdc.gov give additional insight. CDC does not make recommendations about businesses that may offer such services. Your health care provider or local health department may be able to provide additional guidance. Removal of all nits after successful treatment with a pediculicide is not necessary to prevent further spread of head lice. Removal of nits after treatment with a pediculicide may be done for aesthetic reasons, or to reduce diagnostic confusion and the chance of unnecessary retreatment. Because pediculicides are not 100% ovicidal (I.e. Do not kill all the egg stages), some experts recommend the manual removal of nits that are attached less than1 cm of the base of the hair shaft.

According to Terry Burkhart at licefreenoggins.com, head lice are not afraid of the cold weather outside. Parents sometimes assume that head lice are dormant in the cold weather that comes along with winter. After all, most common bugs are no where to be found when the temperatures drops to freezing. Unfortunately, head lice are somewhat oblivious to outdoor temperature. You can stand outside without a hat for hours and nothing will happen to the bugs in your hair. The reason for that is that the temperature of your head will sustain the lice and keep them alive. Head lice need the temperature of the human head and the blood inside to survive.

Liceclinicsnorthgwinnett.com goes on to explain how increasing numbers of consumers are finding that the most popular treatments for head lice – including chemical shampoos and home remedies – are largely ineffective. Head lice are rapidly evolving chemical resistance to many of the traditional pesticide-based control methods . Louse combs can be effective for removing lice and eggs, but the comb-out process can be very tedious, and many busy parents do not have the time or patience for effective combing. In desperation, some parents resort to home remedies such as bug spray, mayonnaise or kerosene, but there is little hard evidence that these remedies are effective, and some home remedies can actually be harmful. As a result, parents and school authorities are searching for a safe, fast and effective treatment that will solve the problem and help keep children in or quickly return them to school.
