Green Bed to Fight Bed Bugs : how the GoodKnight works

GoodKnight self-sterilizing bedBed bugs can be very difficult to get rid of because of their incredible ability to hide in cracks and crevasses. They have also developed resistance to many pesticides.1 The GoodKnight bed offers a unique and effective solution, using a combination of heat-purification technology and built-in trapping system.

Heat Purification Technology

 

Bed Bugs
Heat is known to be very effective at killing bed bugs.2 Heat also has the advantage of being non-toxic, and can kill all life stages of the bed GoodKnight bed - heat-purificationbug, including the eggs. Studies show that temperatures above 49'C (120'F) will kill bed bugs in less than 1 minute.
2 At the lower temperature of 46’C, all bed bugs will die in less than 6 minutes.3 The GoodKnight uses convective heat to bring the mattress and bedding to temperatures above 50'C (122'F) for at least 20 minutes. The treatment is safe, being no hotter than the clothes drier, and effective, killing all bed bugs within the enclosure.

Dust Mites
House dust mites are often a major source of indoor allergens.4 The GoodKnight can play a significant role in reducing dust mites in the sleeping environment by killing them with heat. The target temperature of the GoodKnight, 50'C (122'F) will kill 100% of dust mites in 20 minutes.5

The full GoodKnight heat-purification cycle lasts 3hrs, giving the convective heat enough time to penetrate into the fabric and other materials, reaching pests that may be deeper in the fabric. Below are some other pests that can be eliminated with the GoodKnight.

Built-in Trapping SystemGoodKnight bed built-in defense system


The second part of the invention is based on these well-known entomological facts:
- bed bugs are obligate blood feeders-- if they do not get a blood meal, they die
- they generally feed at night (particularly in the hours before dawn)8

The GoodKnight takes advantage of this behavior, by luring them to the bed at night, and destroying them in the built-in trapping system. There are no migration routes in and out of the bed aside from through these impenetrable traps.

The GoodKnight Edge

Test-pilot studies show that the GoodKnight can provide the user with instant relief from bed bug bites and allows them to sleep undisturbed.

For less than the price of a single exterminator heat-treatment, the GoodKnight user can sleep in the total comfort of a heat-purified bed. The user will also enjoy 24/7 protection from bedbugs, allergy-causing dust mites, and germs, and have the ability to sterilize the bed as often as they want.
