Disclosed herein are robotic devices which traverse a pre-defined coverage area in order to capture and eradicate ticks in the area. A vacuum mechanism provides a suction force for pulling ticks into the device through a frontal opening, after which the ticks are captured in a receptacle and crushed by at least one rotating arm. In certain embodiments, the devices include heat strips near the frontal opening of the device that mimic the human body temperature. Additionally, the device can include carbon dioxide emitters that pass carbon dioxide to the receptacle or through the frontal opening to increase attraction of ticks.
