Method of extermination utilizing heated air
InactiveUS20050246942A1Conducive to pest controlUniform temperature distributionHot-air central heatingOther heat production devicesTemperature stratificationEngineering
A method of exterminating organisms is provided utilizing heated circulating air. First, a determination is made as to which enclosed areas of the building or other structure are to undergo extermination. This step defines an application zone. Next, a desired elevated temperature limit is established for heated air that is to be circulated through the application zone. Heaters are provided in airflow communication with the application zone, and circulation fans are positioned throughout the application zone to move the heated air for proper heat distribution. The heaters utilize an amount of recirculated air already present in the application zone to cut down on the amount of energy needed to raise the air temperature within the application zone towards the desired elevated temperature limit, and to eliminate the need for high CFM airflow heaters to achieve air temperature elevation. The temperature at various nodes within the application zone may be monitored to allow personnel to redirect circulating airflow within the application zone to balance out areas of higher air temperature with areas of lower air temperature. The method takes advantage of convection heat transfer to raise the temperature evenly within an application zone, minimizing temperature stratification which could result in ineffective pest extermination and / or damage to equipment and facilities.

Plant eradication using non-mutating low energy rapid unnatural dual component illumination protocol (RUDCIP) in four parameters
Non soil-invasive four-parameter rapid unnatural dual component selective illumination protocol (UDCIP) for plant eradication using a process time under one minute. Application of a relatively low level of non-mutating UV-A optical energy to root crowns and / or soil grades allows below-ground UV-A penetration into soil to illuminate root crowns, and when preceded by or coincident with an above ground near-IR defoliation and root crown illumination step, results in an unexpected rise in lethality. Very high lethality, including 100 percent, is obtained using low deposited energy. UV-A optical energy can be delivered to root crowns and adjacent soil via a UV-transmissive knive blade.
