Mealybugs feed on the juices of your string of pearls and make it weak.
If you notice some white fluff or cotton-like substance on your string of pearls plant, you might want to check the underside of the leaves where these bugs usually hide.
The mealybugs are tiny bugs that are around 2-3 millimeters long. These are light brown or gray.
Mealybugs expel a substance that invites mold and creates an environment ideal for the spread of fungal and bacterial infections.
It is essential to isolate the plant as these bugs can spread quickly to other plants.
Aphids infest the plant’s tissues and feed on them. It causes stunted growth and disfigured leaves on the string of pearls.

Aphids secrete a sugary substance that promotes the growth of mold in the plant and attracts ants as well.

Whiteflies are white and small insects that can grow large in number within a short time.

Overwatering and keeping the soil most for too long can attract fungus gnats to your string of pearls.
Fungus gnats are small flies that also resemble mosquitoes and are not as harmful as the other pests.

Why does my string of pearls have bugs?
Major reasons behind pest infestation on the string of pearls can be:
- Poor drainage system
- High humidity
- Lack of aeration
- Low light
The string of pearls doesn’t require a lot of water like many other plants. It doesn’t like to sit on water for long and doesn’t enjoy wet soil.
When you overwater the plant, the soil remains moist for a long time, inviting pests. Pests thrive in damp and humid environments.
Not giving sufficient time for the soil to dry out leads to an overwatered plant, so you should always check the soil’s moisture before watering.
You can fix a watering schedule to avoid giving the plant too much water and water only when required. Make sure you check the soil before watering. Only water when the soil feels a little dry.
Poor drainage system
Other than overwatering, having an ineffective drainage system can also attract bugs to your string of pearls.
Using well-draining soil is a must for the string of pearls plant. Such soil will not retain too much water and will help the soil get dry fast.
Ensure that your pot has working drainage holes that let the extra water drain out after you have watered your string of pearls.
Along with a proper watering regime, well-draining soil and drainage holes in the pot are necessary to maintain a sound drainage system.

The string of pearls plant needs an average humidity level of 40-50%, and high humidity can be harmful to the string of pearls.
Keeping a check on the humidity level would be ideal as you will know when to take action if the humidity goes down.
When the string of pearls plant stays in high humidity for a long time, the leaves start yellowing, and it creates an environment that is ideal for the pests.
Lack of aeration
The string of pearls needs soil that allows air to flow between the roots so that the roots remain healthy. They also need good airflow around them to thrive.
Lack of aeration can lead to root rot that will attract pests. It will also not allow the soil to dry quickly, and such a situation can lead to bacterial or fungal growth other than a pest infestation.
The string of pearls enjoys six to eight hours of bright and indirect light. Keeping the plant in low light conditions for too long can bring diseases and pests.
If the plant doesn’t get sufficient light, the soil will remain moist for longer, leading to root rot. Root rot will invite pests that will make the plant weaker.
You can use artificial lights if your house doesn’t have a natural source of light.
