As a subject matter expert in the field of parasitology, I have a deep understanding of the biology and control of various parasites, including head lice. Lice are small, wingless insects that live on the human scalp and feed on human blood. They are highly contagious and can cause significant discomfort and distress. Effective control measures are essential to prevent the spread of infestations.
Cold temperatures can be an effective method for killing lice, but it is important to understand the specific conditions required to achieve this. Lice are ectothermic, meaning that their body temperature is regulated by the environment around them. This makes them susceptible to temperature extremes, including cold.
The reference to a temperature of 130°F (54.4°C) as being effective in killing lice is somewhat misleading. While heat can indeed kill lice, the temperature must be sustained for a certain period of time to be effective. For example, lice can be killed by direct heat at temperatures above 128°F (53.3°C), but this requires exposure for at least 5-10 minutes. However, the temperature mentioned in the reference is actually quite high and is more akin to the temperatures used in heat-based treatments, which are not typically considered "cold."
When it comes to cold temperatures, the effectiveness of killing lice is not as straightforward. Freezing temperatures can be lethal to lice, but the process must be carefully controlled. Lice can survive in cold conditions if they are protected from direct exposure to the cold. For instance, lice can survive in a freezer for several hours if they are inside clothing or other materials that provide insulation.
To effectively kill lice using cold, items that have come into contact with the head of an infested person should be frozen at a temperature of 0°F (-17.8°C) or below for at least 24 hours. This is a common recommendation for items that cannot be washed or dry cleaned. Freezing is a method that can be used for a variety of items, including clothing, hats, and bedding.
It is also important to note that while cold can kill lice, it may not be as effective for killing nits, or lice eggs. Nits are very resilient and can survive in a wide range of temperatures. Therefore, a combination of methods, including washing, vacuuming, and the use of medicated shampoos or lotions, is often recommended to ensure complete eradication of an infestation.
In conclusion, while cold temperatures can be effective in killing lice, it is crucial to understand the specific conditions required. Freezing items at 0°F or below for at least 24 hours is a recommended method for items that cannot be otherwise cleaned. However, for a comprehensive approach to lice control, it is advisable to combine this with other treatment methods to ensure the complete elimination of both lice and nits.

Washing, soaking, or drying items at a temperature greater than 130--F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.Sep 24, 2013
