If it is foreign, please isolate it with a gauze, if it is an insect in the balcony, it is preferred to manually catch it or put a basin of water on the ground at night, hang a light bulb 10 cm from the water surface, extinguish other lights, use the phototaxis of insects, fall into the water and drown. Secondly, use aerosol insecticides.
