How to Kill Lice With Extreme Cold
Lice are bloodsucking parasites that can infest humans and animals. Humans are susceptible to infestations involving several different types of lice, including head lice, body lice and pubic lice. In addition to killing the lice and nits (louse eggs) that are present on the human body, you must also kill the lice and nits that are present on bedding, clothing, hats, and carpeting. Heat can be used to kill lice and nits in the laundry, but some items like hair brushes and helmets cannot be placed in the washer and dryer. For these items, you can use extreme cold in the freezer or outdoors to kill lice and nits.
Place small items (objects that will fit inside the freezer) inside Ziploc bags.
Place the bags inside your freezer for a period of 24 hours. The freezing temperatures will kill the lice and nits 2.
Place larger items like stuffed animals inside a trash bag. Twist the top of the bag closed and wrap tape around the twisted plastic.
Watch/listen to the weather forecast to find a 24-hour period of time when the temperatures will be at or below the freezing mark. Ideally, this period should be precipitation-free.
Place the plastic bags outdoors in freezing temperatures for a period of 24 hours.
If you live in a more temperate location or if you’re dealing with a lice infestation during the summer months, you can use an alternative method to kill lice and nits on large objects that cannot be placed inside the freezer. Leave the infested items inside a sealed plastic bag for a period of two weeks. The lice and nits will die since they cannot access a host. If your home freezer is packed full of perishable food, you can rent a freezer at a home rental shop like Rent-A-Center or Rainbow Rentals. They’ll deliver the freezer (usually free of charge). These rental companies typically rent by the week. You can also take advantage of freezing temperatures outdoors to kill lice and nits on items like car seats, area rugs and car upholstery. These items do not need to be bagged if you can place them in an outdoor location that’s protected from the elements (i.e., a porch or shed). Anti-parasite sprays can be used to kill lice on upholstery and carpeting.

Nits in Hair – Removal and Info
Heat, cold, diligent laundering and dry-cleaning and a special shampoo are all useful in killing head lice that have been plaguing families recently.
What effect does temperature have on lice?
Hot temperatures will kill lice. Such high temperatures are suitable for laundering purposes but not for shampooing the head or for bathing. Hand-held hair dryers do not provide enough heat to kill head lice; if they did, serious burns would result to the surrounding scalp.
Dry Cleaning at High Temperatures Can Kill Lice
The tiny insects can be an especially bad problem in winter because they can get into winter coats, heavy items of clothing people do not want to wash. But without washing these coats, family members can still throw them in the dryer on the hot cycle, or, alternatively, get them dry-cleaned.
The dry cleaning process kills lice also. Dry heat, steam, or pressing with a hot iron will destroy lice since they can live only a few minutes at this high temperature, but, washing with cold or lukewarm water will not kill lice.
Use Cold Winter Temperatures to Kill Lice
Both methods of killing the head lice are highly effective. If they can get the temperature (in the dryer) up to 125 degrees Fahrenheit (52 degrees Celsius) or down to -2 degrees Celsius, that will kill the lice. Though sun-lovers might not agree, a cold snap would be useful in helping to control lice pests. In the event the nighttime temperature should plummet to -20, hang the coats in a garage or anywhere outside in the freezing cold, which can kill the lice and their eggs.
