What to do if gardenia has whiteflies

1. Introduction to pests

This is a worldwide pest that is harmful to most regions and most plant species. The same is true for gardenias. It is easily recognizable by its short feet and wings. Its reproductive capacity is very strong, and the corresponding harm is also great.

2. Prevention and control methods

(1) Wind-blown method: We have also mentioned its appearance characteristics above. So, if faced with strong winds, they will not be able to stay on the plants. If the weather is warm, you can take the plant outside and let it be blown by the natural breeze. However, if the weather is very cold or the wind is very weak, you can also use fans or other means to artificially create strong winds, which can also be very effective.

(2) Spraying: This is the most effective method and can be used to treat large areas of pests. Specifically, you can use trichlorfon or imidacloprid. Once every other week, two or three times in total.

(3) Sticky insect board: This is used when the area affected by pests is relatively small. It can be used to stick the insects to it. However, this method is not suitable when there are too many insects. It consumes too much energy and is not thorough.

(4) Detergent water: This is a controversial method. Some flower lovers found it good after trying it, but some others felt it had no effect. Moreover, it could easily cause harm to the plants themselves. Therefore, this method should be used with caution.

(5) Mosquito coils: For this method, the specific operation is to cover the entire plant with a plastic bag, then poke a few holes and light the mosquito coils. Fumigation for about an hour can effectively suppress pests and diseases.
