A composition includes a gel carrier having a gel phase at a first, ambient temperature and a liquid phase at a second, higher temperature, and an insect repellent chemical in the carrier. The repellent chemical has substantially no volatilization from the gel carrier when the gel carrier is in the gel phase, but volatilizes from the gel carrier when the gel carrier is in the liquid phase.

A system for the remote care of an item of vegetation used as a potential source of food for an animal, to include at least one of a proximity tag, RFID tag, transponder device, a predetermined machine-readable pattern, and geo-location device associated with the item of vegetation, and an aerial drone. The aerial drone includes a microprocessor, a sensor coupled to the microprocessor and configured to detect the at least one of the proximity tag, RFID tag, transponder device, predetermined machine-readable pattern, and the geo-location device, and a carrier configured to carry a substance comprising at least one of a solid, gas, and liquid. The aerial drone is configured to act in response to instructions issued by the microprocessor.

A corrugated cardboard pest repellent system for repelling and/or exterminating various pests around, within, or between layers of a corrugated cardboard construct while reducing the risk of contamination of goods or exposure by handlers. The corrugated cardboard pest repellent system generally includes one or more liners secured by an adhesive to one or more layers of a corrugated medium that has been treated by a pest repellent. The pest repellent is positioned on the underside of each crest of the one or more layers of the corrugated medium to prevent incursion of pests into the corrugated medium. Multiple layers may be stacked to form various constructs including a single face corrugated cardboard construct, a single wall corrugated cardboard construct, a double wall corrugated cardboard construct, and a triple wall corrugated cardboard construct. The resulting constructs may be utilized for various purposes, including forming various types of containers, padding, or liners.

A system of automatically refueled liquid fuel burning torches includes a central fuel reservoir and a pump interconnected with the torches by a fuel plumbing system. When the fuel reaches a lower level in the torches, the plumbing system is automatically pressurized by the pump so that the fuel flows through the plumbing system to raise the fuel to a higher level in the local torch reservoirs. The refueling can be controlled by level sensors and valves in the torches. A remotely operated wick seal can exclude air from torch interiors and prevent fuel spills. A central controller and/or local torch controllers can be powered by wires and/or by batteries, which can be recharged by solar power. The controllers can be wirelessly monitored and/or controlled by software running on a remote device. The remote device and software can control a plurality of the systems.

The present disclosure provides a dual-purpose mosquito repeller for a mosquito-repellent incense tablet and a mosquito-repellent incense liquid, including: a mosquito repeller body. The mosquito repeller body includes: a mosquito-repellent incense tablet heating unit, configured to heat the mosquito-repellent incense tablet to produce a mosquito-repellent smoke; a mosquito-repellent incense liquid heating unit, configured to heat the mosquito-repellent incense liquid to produce a mosquito-repellent smoke. A level switch for switching the mosquito repeller to a different working state is disposed between the mosquito-repellent incense tablet heating unit and the mosquito-repellent incense liquid heating unit. Each level of the level switch corresponds to one working state. Each working state corresponds to an individually-powered-on working state of the mosquito-repellent incense tablet heating unit/the mosquito-repellent incense liquid heating unit, or corresponds to a simultaneously-powered-on working state of the mosquito-repellent incense tablet heating unit/the mosquito-repellent incense liquid heating unit.
