A refill for holding at least two compositions comprises a container including a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated and the second composition is disposed above the first composition. The refill further includes a tube disposed within the body of the container such that the tube contains the first and second compositions, wherein the tube has an inner diameter and an outer diameter. Still further, the refill includes a wick disposed within the tube, wherein the wick contains the first and second compositions and has a diameter that is smaller than the inner diameter of the tube to create a gap between the wick and the tube.

The current subject matter relates to controlling insects and includes a trap that can vary operation based at least on a target insect. For example, different insects are attracted to and/or repelled by different things, such as gases, orders, lights, and sounds. In general, things that attract a given insect are referred to as attractants and things that repel a given insect are referred to as repellents. By varying the operation of the trap, different attractants and repellants can be used to attract and/or repel specific insects. In addition, these attractants and repellants and/or characteristics thereof can these be varied dynamically based on, for example, time of day, proximity of individuals to the trap, proximity of insects to the trap, geographic location, and the like. Related apparatus, system, articles, and techniques are also described.

One nonlimiting variation of a detection arrangement includes one or more sensors each structured to detect at least one biochemical substance indicative of biochemistry of one or more target insect species and provide a corresponding sensor signal, a controller responsive to the sensor signal of each of the one or more sensors to determine if the one or more insect species are present and generate a corresponding output signal, and an indicator responsive to the output signal to indicate the presence of the one or more insect species.

The present disclosure relates to methods and devices for controlling arthropods, including insects and arachnids in an environment. The methods generally comprise: generating a near-ideal gas Purified Hydrogen Peroxide Gas (PHPG) that is substantially non-hydrated (e.g., in the form of water in solution or water in solution or water molecules bonded by covalence, van der Waals forces, or London forces) and substantially free of e.g., ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to control arachnids in the environment. In certain aspects, the arachnids may be totally or partially killed.

Disclosed herein is an insect trapping device comprising an inner passageway structure defining an inner passageway which, when in an upright orientation, extends from an insect entry zone to an insect delivery zone, the inner passageway structure bordered by at least a pair of opposed insect-facing traction-reducing boundary surface regions to cause an insect to progress toward the insect delivery zone under gravity, with each boundary surface region including at least one of at least a pair of electrode surface regions, wherein each electrode surface region is configured for operative coupling with an electrode power supply to deliver electrical power thereto, the electrode surface regions configured to form an electrocution zone therebetween, with a designated spacing which is configured to initiate electrocution of an instance of the insect descending through the electrocution zone.

Devices and methods and pesticidal and/or pest control compositions are disclosed for the control of pests using the vapors of a pesticidal and/or pest control composition. Compositions, devices, methods and vapor forming pesticidal compositions which have improved vapor forming characteristics and are desirable under certain regulatory structures are also disclosed. In some non-limiting examples, the pests are arthropods or nematodes, and more particularly may include bed bugs, fleas, lice, ticks, or the like.

Lighting fixture data hubs and systems and methods for use. An example of a data hub may include an annunciator configured to generate a first indication and a second indication, one or more sensors configured to detect between one or more vehicles and one or more pedestrians and potential convergence thereof within a zone in a vicinity of the data hub and to emit one or more signals corresponding to said detection, and a gateway in communication with an on-board processor and the annunciator, the on-board processor configured to wirelessly receive and analyze the one or more signals, communicate said one or more signals to the gateway so that the gateway can generate the first indication or the second indication in response to the one or more signals. Data hubs may also include a sensor unit housing and/or a light source.

The present invention relates to a formula or composition for use in reducing a honey bee parasitic mite infestation that may comprise, for example, a liquid, solid, or paste composition, comprising about 5-20% beta acids (about 5-75% by weight), about 5-75% by weight propylene glycol, about 5-75% by weight polysorbate 60, about 0.5-35% of a thixotropic material comprising, for example, fumed silica, and/or about 0.5-5% of an antioxidant comprising, for example, ascorbic acid, the composition is active against parasitic mites for more than about 14 days in the bee hives. Compositions of the present invention provide effective control, treatment, or prevention of honey bee parasitic mite infestation by inclusion of, for example, certain excipients that retard beta acid oxidation, prolong availability of active ingredient for bee uptake, improve convenience for beekeepers, or both retard beta acid oxidation and prolong the availability of active ingredient for bee uptake.
