1. Use high-pressure gas cylinders to grabThe rose and peanut bugs can be killed by using a high-pressure gas cylinder used to kill flies at home. Just spray it twice on the stems and leaves. It is very effective against common pests. Because the bottle contains cypermethrin or chlorpyrifos, it can effectively kill pests and is harmless to the human body. 2. Use a lit mosquito coilPlace a lit mosquito coil next to the plant; the smell it emits can kill pests. Because mosquito coils also contain cypermethrin or chlorpyrifos, they will produce smoke after burning, which will gradually rise and then kill the pests. The method is also very simple. 3. Artificial captureWhen there are insects on roses, you also need to observe what specific type of pest they are. If it is a slightly larger pest such as scale insects or large green leaf eaters, you can catch them directly with your hands once you find them. This method is simpler and more effective, and will not pollute the indoor environment. |
