An apparatus for vaporizing and dispensing a pesticide features an elongated body structure, and heatsink attached to the elongated body structure at a distal end thereof. A loading port on the elongated structure feeds solid pesticide material into a closed-ended vaporization chamber inside the heatsink via a delivery passage running longitudinally of the elongated structure. A heater is operably arranged with the heatsink to vaporize the solid pesticide material. The heatsink interior features a second exhaust chamber that is radially offset from the vaporization chamber, and is only fluidly communicated therewith by a radial port near the end of the vaporization chamber fed by the delivery passage. The loaded solid pesticide falls past the radial port into the vaporization chamber, while the resulting vapor is forced through the radial port into the exhaust chamber by pressurized air fed through the delivery passage.

A scented wafer having a body formed of a heat resistant fibrous material having a predetermined porosity resulting from a selected denier and length of fibers. A scented material is impregnated into the body material and is constructed to melt and release a scent when exposed to heat at a predetermined temperature for aromatherapy, insect repellant, wild life attractant, medicinal use, deodorant and odor control, perfume release, or any other desired or suitable purpose. The body material does not melt at the predetermined temperature.

A dispenser of parasiticidal substances comprises at least one tank containing a parasiticidal substance, leading to an ejection device for expelling the parasiticidal substance, suitable for being filled with parasiticidal substance and for emitting it as a result of an increase in the temperature.

Provided is an insect pest control product that is applicable to a water-based insecticidal composition and can continue to exert stable performance over a long period of time. The insect pest control product comprises a thermal vaporization/diffusion absorbent wick for vaporizing and diffusing a water-based insecticidal composition containing a pyrethroid insecticidal component having a vapor pressure of 210.sup.4 to 110.sup.2 mmHg at 30 C., a glycol ether compound and/or glycol compound having a boiling point of 150-300 C., and water. The thermal vaporization/diffusion absorbent wick has an insecticidal component/compound condensation ratio (P.sub.1/P.sub.2) within the range of 1.2-6.0, where the insecticidal component/compound condensation ratio (P.sub.1/P.sub.2) is calculated from a weight ratio (P.sub.1) of the pyrethroid insecticidal component and the glycol ether compound and/or glycol compound contained in the thermal vaporization/diffusion absorbent wick after use, and a weight ratio (P.sub.2) of the pyrethroid insecticidal component and the glycol ether compound and/or glycol compound contained in the water-based insecticidal composition before use.

An insecticide fumigator including a chemical cartridge mount on which a chemical cartridge is configured to be mounted, a heater disposed near the chemical cartridge mount and configured to heat the chemical cartridge such that an insecticide in the chemical cartridge is evaporated from a fumigation part of the chemical cartridge, a light source disposed near the fumigation part and configured to emit light having a first wavelength range to attract insects, and a housing provided with the chemical cartridge mount and receiving the heater and the light source, in which the light source includes a UV LED and a substrate on which the UV LED is mounted, and the housing has a light passage hole through which light emitted from the light source passes.

An evaporator is provided, for use with a wicked reservoir containing a volatile liquid. The reservoir has a plurality of guide members disposed symmetrically around the wick and extending beyond the height of the wick. The evaporator features a base containing a battery, and a removable cover containing a heater. Attachment of the cover to the base is necessary to establish an electrical connection between the battery and the heater. The guide members fit into recesses in the cover only when the heater and wick are properly aligned, and the heater cannot make electrical connection with the battery unless the guide members and wick are properly aligned with the recesses and heater, respectively.

Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element is a pest control vaporizer or pesticide vaporizer that is used to protect bees from certain pests, mites, and insects where the pesticide vaporizer expels a vapor that kills harmful pests, mites, and insects but does not harm or affect bees in the colony. Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element includes an integral body tube that is without any holes, perforations, punctures, gaps, vents, or discontinuities. Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element includes a detachable proximal end air nozzle. Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element includes a floating heating element with a floating electrical connection.
