An apparatus for deterring flies by reversing their flight path has a transparent container that includes a plurality of outwardly facing planar surfaces. A liquid, preferably water, is disposed in the container. A penny or similar planar object formed of copper is preferably secured at each outwardly facing planar surface. Planar objects formed of a material other than copper or having a different color, shape, or varying degree of reflectivity can be used instead of or along with the penny. A hook or other means for hanging the container is provided. An optional battery or AC powered motor may be included to rotate the device around a center vertical axis. A less expensive version that is formed of a flexible transparent plastic container is also shown and described. The containers are either filled with liquid and sealed or are fillable by the user.

A repellant system for repelling nuisances such as insects from an area around a surface such as a table. The repellant system generally includes a base, a first receiver extending from the base, a first linkage frictionally adjustable within the first receiver, a second receiver adjustably connected to the first linkage, and a second linkage frictionally adjustable within the second receiver. A motor in the base may be utilized for automated rotation of the first receiver on the base. An adjustment connector links the first linkage with the second receiver. A pair of mounts on the second receiver and second linkage removably retains a sheet roller which dispenses a sheet which will deter insects and other nuisances.

The invention relates to a method for producing a bird protection device arid to a bird protection device. According to the invention, a method for producing a bird protection device is proposed, wherein the bird protection device is made of an at least partially transparent material and contains an optical structure visible to a bird's eye. Here, the method comprises a radiation input, wherein the radiation input is implemented on and/or in the partially transparent material for forming the optical structure. The radiation input is preferably laser radiation. Suitable lasers for the radiation input are, for example, CO2 lasers with a wavelength of 1064 nm, picosecond lasers with a wavelength of 532 nm or nanosecond lasers with a wavelength of 532 nm. In one embodiment of the invention, the bird protection device furthermore comprises an element for increasing the contrast, wherein, for forming the optical structure, the radiation input is implemented on and/or in the element for increasing the contrast.

Disclosed are embodiments of a pest repellent device and methods of operating the pest repellent device. The device can comprise a device body having a first body end and a second body end, a blade motor housed within the device body, a rotatable component disposed at the first body end, one or more fan blades coupled to the rotatable component, and a foldable base assembly coupled to the second body end.
