1. A computer-implemented method comprising:
obtaining sensor data captured by a sensor of a property monitoring system;
detecting an object represented by the sensor data;
determining, using a first sensor analysis process, that the object is a potential object of interest;
in response to determining that the object is the potential object of interest, determining, using an audio sensor connected to an audio analysis engine, that the potential object of interest is not likely to be an object of interest, wherein the audio analysis engine generates an audio analysis result indicating that a recorded audio includes a sound of an arthropod; and
in response to determining that the potential object of interest is not likely to be the object of interest, sending, to an ultrasound emitter, a command to cause the ultrasound emitter to emit ultrasonic sound around the sensor.
