A method for insect repelling and an apparatus using the same are provided. The disclosed apparatus comprises a housing; an electromagnetic radiation generating module having a first radiation source being capable of emitting a first electromagnetic wave and arranged on the housing such that the electromagnetic radiation generating module uses the first electromagnetic wave to provide a radiation to the defined area or space; the first electromagnetic wave being an infrared in the wavelength of 700 nm to 1 mm, an ultraviolet in the wavelength of 10 nm to 400 nm or a spectrum-specific visible light in the wavelength of 490 nm to 580 nm; and a controller module residing within the housing to electronically communicate with and control the electromagnetic radiation generating module. Preferably, the radiation is pulsed at a predetermined frequency.

A system for dredging a seabed includes a trailing suction hopper dredger. The trailing suction hopper dredger includes a hull, a rail coupled to the hull, and a dredge arm coupled to the rail. The dredge arm includes an upper suction pipe coupled to a lower suction pipe. A pump is coupled to the upper suction pipe and is configured to draw material toward the upper suction pipe from the seabed. A visual marine life deterrent is coupled to the dredge arm and is configured to direct light toward the sea floor where marine life may be located. Another visual marine life deterrent includes a silhouette of a marine life predator. The visual marine life deterrents are configured to be observable by the marine life and cause marine life to move away from the dredge arm.
