A method of deterring avian pests from a space includes adding an amount of methyl anthranilate to an evaporator disposed in a space. The evaporator can be passively or actively operated to increase or decrease the off-gassing of methyl anthranilate.

Systems, apparatuses, and/or methods to protect an entity. A detector may detect an animal proximate to an entity based on sensor data from a plurality of sensors. The plurality of sensors may be positioned, for example, on the entity. In addition, a protector may administer a mechanical repellant from a protection device to repel the animal proximate to the entity. The mechanical repellant may include, for example, an ultrasound wave, a vibration wave, and so on. Moreover, the mechanical repellant may be specific to a type of animal to repel the animal proximate to the entity. The mechanical repellant may further be harmless to the animal (or the entity) and/or inapplicable to at least one other animal in the environment.

The present disclosure provides a LED rat repellent light, comprising an LED assembly, a rat repellent assembly and a light socket, wherein the rat repellent assembly is arranged between the LED assembly and the light socket. The rat repellent assembly comprises: a connecting shell having a first connecting shell end and a second connecting shell end. The rat repellent assembly also includes a middle frame having a first frame end, a second frame end, and a side wall. The first connecting shell end is connected to the light socket, the second connecting shell end is connected to the first frame end, and the second frame end is connected to the LED assembly. The middle frame further comprises at least one opening arranged on the side wall thereof. The rat repellent assembly further includes an ultrasound emitter, arranged in the connecting shell, wherein the ultrasound emitter has an surface facing the middle frame. The rat repellent assembly also includes a reflective panel, arranged in the middle frame, wherein the reflective panel has a first side extruding towards the ultrasound emitter. In operation, ultrasound output from the ultrasound emitter is reflected on the first side of the reflective panel and then passes through the opening on the middle frame.
