Bedbugs (Cimex lectularius) are on the rise nowadays in hotels, bed and breakfasts, even on public transport. They have been on the rise in the past 6 to 8 years, even in highly industrialised European countries.
Bedbugs like to nest in crevices and hollows in beds and sofas. They hide in folds in mattresses, cracks and crevices, in the springs or behind the head of the bed, in bedside tables, paintings, skirting boards, even on electric cables and switches.
Professional disinfectors know how hard bedbugs can be to deal with.
The superheated dry steam of the Polti Cimex Eradicator has proved to be the innovative and effective solution of eliminating the problem of bedbugs.
The special feature of this system is the type of steam which, after being generated inside a boiler as in conventional steam generators, is further superheated inside the delivery nozzle (patented worldwide by Polti) up to a maximum temperature of 180°C.
At the time of delivery, the steam is mixed with the HPMed sanitising liquid, a water and alcohol-based solution containing sodium metasilicate and sodium carbonate, which can be delivered in the presence of people.
The flow of steam at 180° C is able to eliminate the adult insects, the larval stages and the eggs because it causes their thermal shock.
In vitro experiments and in the field tests have demonstrated the effectiveness of the superheated dry steam for the rapid elimination of bedbug In the laboratory tests, a variety of different materials (wood, fabrics, metal, etc.) were used to artificially reproduce some of the most common places where bedbugs nest. In each of these simulations the experimenters nested adult insects and larvae (tests conducted on bedbugs in their mobile stages) or pregnant females (tests conducted on eggs) in the materials.
A single treatment with superheated dry steam has been able to eliminate all the eggs present and a very high proportion of the adult insects and larval stages.
In the field tests, actual infested contexts were selected, such as hotels and private homes, and were treated with superheated dry steam.
The results obtained in the experiments were highly positive. Unlike chemical products, which require three or four treatments to achieve complete disinfestation, the superheated dry steam of Cimex Eradicator completely eliminated the infestation after two or three treatments.
Targeted treatment with superheated dry steam was demonstrated to be effective for eliminating bedbugs and represents a faster alternative with lower environmental impact than use of potentially toxic chemicals.
In addition, disinfestation with conventional chemical insecticides requires complete evacuation of the premises and ventilation before they can be used again, involving lengthy waiting times.
The superheated dry steam can be used even when there are people in the room, as the mixture of superheated dry saturated steam and HPMED is not harmful to humans.
