Benefits of technology

The present invention provides an improved technique for exterminating pests through thermal treatment. The technique involves using heated air to reach a target eradication temperature in a treatment zone. The air is discharged at a variable temperature and volume rate to efficiently and quickly reach the target temperature. The ramp-up rate of the temperature is controlled to prevent damage to the structure and to trap and kill pests before they can escape. The treatment zone temperature is set to be between about 120°F and 140°F for most applications. The technique is effective for mammals, reptiles, and other pests, and can also be used to reduce or eliminate non-toxic forms of micro-organisms. The extermination operation is efficient and can be completed in a short time.

Problems solved by technology

These techniques involve certain risks to personnel, as well as to the environment, and hence are not readily undertaken without necessary precautions.
Some are environmentally unfriendly.

Embodiment Construction

[0021] In accordance with the preferred embodiment of the present invention, the thermal treatment of a zone for extermination of pests is undertaken as follows. It is believed that the recitation of steps set forth below will enable those of skill in the art to readily and effectively practice the technique.

Treatment Zone Defined

[0022] The dimensions, type of structure, as well as area of structure for heat treatment is analyzed and determined. This determination enables the technician to establish some basic guidelines for the equipment necessary to effectively handle the procedure. Accordingly, the nature of the heat source and fuel supply is determined, along with the equipment installation factors.

[0023] The step of defining treatment zone air flow is then undertaken with respect to heat movement, air distribution, placement of the equipment being utilized, and desired locations for heated air inlet and discharge. This step may generally be characterized as the determination...

Abstract

A method of pest control which includes heating the affected area to a temperature which is lethal for the pests being exterminated, and maintaining this elevated temperature in the zone for a predetermined period of time. The treatment is undertaken after determining the air flow parameters for the treatment zone, so as to be able to determine the CFM requirements for achieving a requisite air flow rate of between 0.5 and 70 air changes per hour in the treatment zone. Heated air is introduced to the treatment zone at the requisite air flow rate and at an initial temperature of at least about 240° F., with the temperature in the treatment zone being elevated at a predetermined rate until the air temperature reaches a predetermined set point. Once the predetermined set point temperature is reached within the treatment zone, the introduced heated air is adjusted to an eradication temperature and maintained in such a condition for a predetermined period of time sufficient to eradicate respective pests within the treatment zone.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to a method for exterminating pests by thermal treatment of enclosed pest-occupying zones, wherein the zone is treated with heated air under controlled conditions for a period of time sufficient to achieve extermination of the pests. The term “pests” is intended to refer generally to creatures such as insects, mammals, reptiles, and the like, but may also include some other undesirable but non-toxic forms of matter such as certain types of bacteria, molds, and viruses. BACKGROUND OF THE INVENTION [0002] In the past, various techniques have been employed to exterminate pests, including the introduction of toxic or lethal gases, such as those used in typical fumigation techniques including methyl bromide, phosphine, or the like. These techniques involve certain risks to personnel, as well as to the environment, and hence are not readily undertaken without necessary precautions. Some are environmentally unfriendly. O...
