A method for multi-agent dry fogging. The method includes pressurizing a first agent to a first range of pressure. The first agent includes a sterilant. The method also includes pressurizing a second agent to a second range of pressure. The second agent includes a non-depleting solution for protection against microorganism growth. The method also includes pressurizing a gas to a gas range of pressure. The method also includes atomizing the first agent at a nozzle to mix with the pressurized gas in a first application stage to disperse the first agent in a first dry fog within an ambient environment. The method also includes atomizing the second agent at the nozzle to mix with the pressurized gas in a second application stage to disperse the second agent in a second dry fog within the ambient environment.

Burrowing rodents and other burrowing pests are particularly difficult to eradicate, especially around household pets that like to dig up the rodent mounds in pursuit of the animal. This gas distribution device and the method for using the device was invented to increase the effectiveness of introducing a poisonous or repellent gas into the subterranean tunnels created by burrowing animals such as but not limited to mice, gophers, moles, rats, voles, and various insects. The distribution device can deliver large amounts of poisonous or repellent gas into the subterranean tunnels through the gas distribution chamber using supplied air to assist or without the supplied air assistance. By increasing the effectiveness of distributing poisonous gas throughout subterranean tunnels you may eliminate the need to use traps and poisonous bait that could injure a household pet or livestock.

An oxalic acid vaporizer for vaporizing oxalic acid crystals in a bee hive with a bee entrance for treatment to kill mites on bees and in the bee hive has a cup to hold oxalic acid crystals with a resistive heating element mounted on one end of an extension. A handle is mounted on the other end of an extension with internal resistive heating element wires passing from the heating element to an internal circuit board with a microcontroller. A rocker switch is mounted on the handle connected to the circuit board. An LED is mounted to the handle connected to the circuit board. An external electrical cord connected to the circuit board and extending out of the handle with a positive battery post clamp and a negative battery post clamp is adaptable to be connected to a 12 volt battery.

The present invention relates to a photocatalytic film including at least one polymer layer (1) including at least one photocatalyst, said layer being pervious to both the vapors of at least one fumigating compound and ultraviolet radiation capable of activating the photocatalyst. The present invention also relates to a method for treatment by fumigation using said photocatalytic film and at least one fumigant.

The invention relates to a device for dispensing volatile substances, having a housing (2), a container (5) for the substance to be dispensed, a wick received in the container (5) and protruding from the container (5) with a wick end (6) forming a substance dispensing area, and further having an electrical heating device (8) which has an electrical heating circuit, the heating device (8) being displaceable relative to the wick end (6) in order to set a substance delivery rate. According to the invention the electrical heating circuit of the heating device (8) comprises a thermoswitch (16) being openable by heat exposure at a predetermined switching temperature and being arranged at a distance from the wick end (6), the thermoswitch (16) being switchable as a function of the distance between the heating device (8) and the thermoswitch (16).

A system and method for eradicating burrowing rodents uses an internal combustion engine running at high speed and zero mechanical load to convert gasoline and air into pressurized carbon monoxide entrained in an inert gas mixture consisting mostly of nitrogen and water vapor. A heat exchanger cools the exhaust gas and provides it to one or more outputs. Respective hoses are coupled to the outputs, with each hose coupled to an injector tube adapted for insertion into a subterranean tunnel in which a rodent may be present. The engine is preferably mounted on a wheeled tubular frame which may be part of a hand truck or a trailer frame, with the frame serving as both structural member and as heat exchanger. The system pumps gas into the tunnel, replacing the existing atmosphere with oxygen poor, CO rich gas that causes the rodents to succumb to a combination of CO poisoning and hypoxia.
