Abstract
A release device for a vaporizable and/or sublimateable pesticide is provided. The release device is suitable for use against subterranean pests (e.g. fire ants). The release device may be driven into and/or placed in a cavity within the soil or other substrate where the pests reside. The release device comprises a vapor injector which releases the pesticidal composition through apertures into the pest habitat, where it is distributed in vapor form.
Claims20
A pesticide release device configured for delivering a vaporizable and/or sublimateable pesticidal composition in vapor form to a pest habitat, comprising:
- a rigid vapor injector extending along an axis from a distal end to a proximate end and defining:
- a chamber internal to the vapor injector;
- and
- a plurality of apertures along a surface of the vapor injector and in communication with the chamber, the plurality of apertures configured to allow the vaporizable and/or sublimateable pesticidal composition to flow from the chamber through one or more of the plurality of apertures into the pest habitat.
A method of pesticidal treatment comprising:
- inserting a vapor injector containing a vaporizable and/or sublimateable pesticidal composition into substrate containing a pest habitat;
- and
- causing, by the inserting, the vaporizable and/or sublimateable pesticidal composition to flow through one or more apertures of the vapor injector into the pest habitat, the vaporizable and/or sublimateable pesticidal composition being in vapor form in at least a portion of the pest habitat.
A kit of parts for a pesticide release device configured for delivering a vaporizable and/or sublimateable pesticidal composition in vapor form to a pest habitat, comprising:
- a rigid vapor injector extending along an axis from a distal end to a proximate end and defining:
- a chamber internal to the vapor injector;
- and
- a plurality of apertures along a surface of the vapor injector and in communication with the chamber;
- a vaporizable and/or sublimateable pesticidal composition for delivery by the vapor injector.
