Also from the U MN bed bug website: "However, based on related research, a two-hour core exposure at 120°F (45°C) should be considered a minimum target temperature for heat treatments. For freezing, a minimum of 23°F (-5°C) must be maintained for at least 5 days. As the temperature is decreased, the time of exposure is shortened. For instance, the articles could be "flash frozen," resulting in a very short time of exposure, but the target temperature should be -15°F (-26°C), the conditions required to instantly freeze the eggs. Keep in mind that most household freezers will have varying temperatures between 30°F and 20°F, and a 2-week freeze time is recommended if you are uncertain of the freezer temperatures." Lou Sorkin

If people don't want to use heat treatment and have access to low temperature and follow the protocols, that should work, right? http://www.nytimes.com/2012/12/06/garden/bedbugs-hitch-a-ride-on-library-books.html?pagewanted=all Emily From: ad...@museumpests.net<mailto:ad...@museumpests.net> [mailto:ad...@museumpests.net]<mailto:[mailto:ad...@museumpests.net]> On Behalf Of bugma...@aol.com<mailto:bugma...@aol.com> Sent: Sunday, August 26, 2012 4:54 PM To: pestlist@museumpests.net<mailto:pestlist@museumpests.net> Subject: Re: [pestlist] heat treatment This is a message from the Museumpests List.

When pest management firms super heat a home for bed bugs, they leave the heat for the better part of the day to insure it reached that level in all materials and areas of the home. When it comes to killing insects in wood, commercial kiln-drying of lumber only reaches about 108 to 115. Often larvae in wood are not killed in the kiln because the wood is a good insulator. I've been involved in powderpost beetle, wood-boring wasp larvae, and old house borer infestations in kiln-dried lumber, including hardwood flooring. An easy method for items of lesser value, is to place a pan of water on the bottom rack of a kitchen oven in order to maintain high humidity in the oven. Place the object directly onto an upper rack. Then turn the oven to its "warm" setting, which usually is 170 degrees Fahrenheit. Leave the object in for 3 hours and then turn the oven off, leaving the object inside. When the oven is cool, you can remove the object. I've used this method for powderpost beetles in objects purchased by tourists in various countries. It can probably also be used for certain kinds of fabrics made of natural materials. I would not try it on synthetic fabrics; they might melt.
