The invention discloses a flowerpot facilitating deinsectization. The flowerpot comprises a flowerpot body, a pesticide preparation box, a pesticide storage box, a water pump and a controller. The pesticide storage box, the water pump and the flowerpot body are sequentially arranged in the horizontal direction, the pesticide storage box is arranged above the pesticide preparation box, a pesticide dosing opening capable of being opened and closed is formed in the lower portion of the pesticide storage box, and when the pesticide dosing opening is opened, liquid pesticide in the pesticide storage box is dosed in the pesticide preparation box below. A water inlet and a water outlet are formed in the water pump, and the water inlet is communicated with the interior of the pesticide preparation box. A pesticide conveying pipe is arranged on the side upper portion of the flowerpot body, and a sprayer is arranged at the end of the pesticide conveying pipe. The water outlet is communicated with the pesticide conveying pipe. According to the flowerpot facilitating deinsectization, automatic pesticide preparation and spraying are adopted, the trouble of manual pesticide preparation is saved, pesticide can be rapidly prepared and sprayed for deinsectization, and the function of reminding people to add water and the pesticide in time is achieved through the arrangement of a liquid level sensor and an alarm.
