By sucking out the sap of the plants, they weaken the plant’s structure, which can cause the plant to fall over. The best way to think of the liquid in a plant is that it is the blood of people and animals. As the plant loses the sap that contains precious nutrients that are no longer going to parts of the plant, other areas can suffer.


Plus, insects that open the plant to suck the sap out can lead to fungus and other types of diseases, which can cause even more damage to the plant.

Introducing ones that are not familiar with your climate might not work as effectively as you might like. Second, when you add ladybugs to your home, you might start to smell a foul odor. Ladybugs can give off an unpleasant odor, so consider that if you plan to drop hundreds of these insects into your greenhouse or another type of plant environment.
