What should I do if my gardenia has small black bugs
The small black bugs on gardenias are thrips. The most effective way to deal with them is to use pesticides. Pyrethrin or acetamiprid are commonly chosen. It's best to add some brown sugar when mixing the pesticide to make the pesticide adhere to the plant, which can double the effect. When applying the pesticide, make sure to spray both sides of the leaves. Generally, it will take effect after two to three applications. It's best to do this in the afternoon. Additionally, you can use blue sticky traps. Thrips are attracted to light, and the sticky traps can also help control them.
