[0017] Typical pouches are slightly larger than the contents they were designed to hold. For example, in the case of mattresses and box springs, the bag is large enough to accommodate box springs and / or mattresses being loaded into and removed from the bag, but not much larger. In the case of personal items, the bag is large enough to hold a certain number of personal items, while allowing sufficient air space around the items to circulate carbon dioxide. The bag is preferably durable enough to move items into and out of the bag. In some embodiments, the bag is made from multiple layers (eg, 2 layers, 3 layers, or 4 layers) of material. Exemplary materials include polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, nylon, vinyl, canvas, paper, or a combination of two or more materials. Preferred materials are durable and able to withstand rips and tears, yet flexible enough for storage, folding and easy transport. The material or combinati...

[0033] Example 1 - Efficacy of carbon dioxide in killing all life stages of bedbugs

[0034] Example 1 tested the efficacy of carbon dioxide to kill all life stages of bed bugs. To test efficacy on eggs, eight fed adult female bedbugs and two fed adult male bedbugs were placed on fresh filter paper to lay test eggs over a 7 day period one week prior to testing and direct fast feeding. On day 7, 24 hours prior to testing, the filter paper with adults and eggs was placed in a refrigerator at 10°F for 10 minutes. This is long enough for adult bedbugs that they are easily removed from the filter paper by tapping very gently. Adult bedbugs are removed without the eggs being removed. Eggs were counted and placed in air-permeable containers. The container is placed inside an enclosure, the enclosure is sealed, and the treatment is applied. Use CO 2 The meter tracks the concentration of carbon dioxide. After an exposure time of 20 hours, the containers were removed from the en...

Abstract

The present disclosure relates to treating articles suspected of being infested with bed bugs using carbon dioxide.

Description

Background technique [0001] Some methods of bed bug management require discarding items suspected of being infested by bed bugs. These items can be expensive or difficult to replace, especially in the case of bulky items such as furniture, mattresses and box springs, or in the case of personal possessions. Some methods of bed bug management rely entirely on pesticides, which may be restricted or prohibited on certain items, especially those that come into contact with people. Other methods of bedbug treatment can damage items. [0002] It is against this background that the present invention is made. Contents of the invention [0003] Surprisingly, it has been found that objects can be treated with carbon dioxide. [0004] Accordingly, in certain aspects, the present invention is directed to a method of treating an article suspected of being infested by bed bugs, the method comprising placing the article inside an enclosure, releasing CO 2 into the enclosure, seal the en...
