Abstract
Devices and methods for the control of pests using the vapors of a pesticidal composition. Compostions, devices and methods for the selective control of pests while not harming one or more beneficial insects are also disclosed. In some embodiments, the pests are bed bugs, fleas, lice, ticks, or the like. In some embodiments, the pests are varroa mites and the beneficial insects are honey bees.
Claims26
A method of killing a pest, the method comprising:
- providing a treatment enclosure containing pests or their eggs, or an article infested with pests or their eggs, the treatment enclosure having a volume of between 70 L and 1200 L;
- providing a substrate impregnated with a pesticidal composition;
- and
- passively releasing pesticidal vapors of the pesticidal composition from the substrate within the treatment enclosure for a treatment period, wherein the pesticidal composition comprises neem oil;
- wherein the concentration of neem oil in the pesticidal composition comprises in the range of about 0.00055% to 0.013% by volume per volume of the treatment enclosure.
A method of killing a pest, the method comprising:
- providing a treatment enclosure containing pests or their eggs, or an article infested with pests or their eggs;
- and
- releasing pesticidal vapors within the treatment enclosure for a treatment period, the pesticidal vapors being released from a composition comprising neem oil wherein:
- the treatment enclosure has a volume of between 70 L and 1200 L;
- and
- the step of releasing pesticidal vapors within the treatment enclosure comprises:
- providing a substrate impregnated with a pesticidal composition;
- and
- passively releasing pesticidal vapors of the pesticidal composition from the substrate within the treatment enclosure for a treatment period, wherein the pesticidal composition is applied at a concentration in the range of 0.01% to 0.2% vol/vol relative to the volume of the treatment enclosure in which it is applied;
- wherein the pests comprise terrestrial arthropods.
A method of killing a pest, the method comprising:
- providing a treatment enclosure containing pests or their eggs, or an article infested with pests or their eggs, the treatment enclosure comprising a structure for fully or partially sealing the treatment enclosure, the structure comprising a flexible outer layer that is impermeable or substantially impermeable to pesticidal vapors;
- providing a substrate impregnated with a pesticidal composition;
- and
- passively releasing pesticidal vapors of the pesticidal composition from the substrate within the treatment enclosure for a treatment period, wherein the pesticidal composition comprises neem oil;
- wherein the concentration of neem oil in the pesticidal composition comprises in the range of about 0.00055% to 0.013% by volume per volume of the treatment enclosure.
A method of controlling a pest by killing the pest, the method comprising:
- providing a treatment enclosure containing pests or their eggs, or an article infested with pests or their eggs, the treatment enclosure comprising a structure for fully or partially sealing the treatment enclosure, the structure comprising a flexible outer layer that is impermeable or substantially impermeable to pesticidal vapors;
- providing a substrate impregnated with a pesticidal composition;
- and
- passively releasing pesticidal vapors of the pesticidal composition from the substrate within the treatment enclosure for a treatment period, wherein the pesticidal composition comprises neem oil.
