The present subject matter relates to devices, systems, and methods for applying pesticides, herbicides, and other treatment chemicals to a surface. A roller application device for use in delivery of treatment chemicals to a landscape surface includes a handle assembly having a fluid connector configured to be connected to a treatment chemical source, and a roller applicator is connected to the handle assembly but configured to rotate about an axis. The handle assembly includes a fluid dispenser configured to deliver a treatment chemical from the treatment chemical source to the roller applicator, and the roller applicator is configured to absorb the treatment chemical in an outer surface of the roller applicator and transfer the treatment chemical to a surface upon contact with the surface.

A device that confines a water soluble larvicide or insecticide or other solid or semi-solid chemical medium that allows for a measured dispersal with a means for affixing to a rain gutter or open water container susceptible to harbor or breed mosquito larvae.

A backpack sprayer includes a housing, a spray nozzle assembly, a fan assembly and a switch assembly. The housing is configured to contain a liquid. The spray nozzle assembly is communicated with the housing, and is configured to spray the liquid out from the housing. The fan assembly is connected to the spray nozzle assembly, and is configured to provide the spray nozzle assembly with power to spray the liquid out from the housing. The switch assembly is connected to the spray nozzle assembly and electrically connected to the fan assembly, and is configured to control opening and closing of the spray nozzle assembly and start and shutdown of the fan assembly simultaneously.

Apparatuses, methods and systems provide technology to detect a pest-related fault or failure of an electronic control unit (ECU). The technology may also detect a presence of one or more pests via cameras, LiDAR sensors, RADAR sensors, motion sensors, one or more sound sensors, or one or more heat sensors. The technology may also provide countermeasures to disable, remove or eradicate the pests from the vehicle. The countermeasures may include one or more of a laser to target small pests, an electrical discharge insect control system to exterminate insects, and a vibration or sound emission system to target rodents.

A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

A portable, heated scent, odor, and/or molecule dispense system is provided, as well as devices and methods for doing the same. The portable systems and methods to dispense molecules may contain a liquid, gel, solid, foam, or other material-based formulation so as to attract, repel, kill, mask, or otherwise use the molecules. The portable system and methods may include a housing; a molecule holding pad in the housing; a first chemical reaction heat source in the housing; and a second chemical reaction heat source in the housing, wherein the molecule holding pad is arranged between the first chemical reaction heat source and the second chemical reaction heat source, and wherein the first chemical reaction heat source and the second chemical reaction heat source are each reactive to oxygen.

A device for diffusion of a liquid product, of the perfume type, stored in a reservoir includes at least one fixed part capable of being mounted on the reservoir, and offering at least one point of product supply by capillarity, the fixed part including a fixed porous body capable of being impregnated with product by capillarity by being directly immersed in the reservoir. The device also includes a nomadic element for each supply point, including a mobile porous body capable of being impregnated with product by capillarity while being in contact with the fixed porous body when the nomadic element is mounted on the fixed part. The nomadic element also includes a decorative structure of the jewel type, the mobile porous body being housed inside the decorative structure.

A plug assembly having an insert having an aperture extending from a first end of the insert to a second end, the aperture defining a tapered female thread tapering from a larger diameter towards the first end to a smaller diameter towards the second end, and a plug having a head portion and a base portion, and a tapered male thread located between the head portion and the base portion, wherein the plug is adapted to screw into the insert to secure the plug in the insert.
