Scale insects are often produced because of poor ventilation, air humidity and other factors. The larva mainly inhabits on the back of the leaves, sucks the plant's body fluid, and injects the digestive fluid into the injured plant, which makes the wound of the injured plant not easy to heal. This kind of pest can secrete excreta with high sugar content, which will attract ants and easily cause secondary infection, i.e. soot disease.
When there are few insects, you can wipe them with cotton ball vinegar or alcohol, or soak the plants in water directly. If you have more, you can use special killing drugs.
This kind of insect is easy to find, because the climbing place will present bright and transparent mucus, which is easy to identify. This kind of insect licks the suction mouthpiece with it, causing damage to the plants, especially the new tender leaves. However, it is rare in family breeding. Once it appears, it is necessary to kill several.
Red spider is a bad thing. It mainly smells on the leaves of air pineapple. It absorbs water from the plants and causes them to be dehydrated and shriveled. It usually occurs at high temperature and dry time.
It is not difficult to find the spider on the leaf. Once found, it can be washed away with water. In addition, proper increase of humidity can avoid the appearance of spider.
