Larvae of many different types can cause damage to your plants.
SYMPTOMS & IDENTIFICATION
Larvae mainly harm the leaves of your plants, causing unsightly and irregularly-shaped holes
Can be found on the underside of leaves, on the steam, in the soil or under the pot
The easiest and fastest way to control an infestation is to manually remove the larvae and place them somewhere else.
But in more serious cases:
There are many different types of bacteria you can mix in the soil that will kill intruders like this.
If this doesn't work you can always use traps, barriers and repellents that are specialized for keeping larvae away, and in worst-case scenarios, there are many different types of effective pesticides.
CAN I AVOID THIS FROM HAPPENING AGAIN?
Always quarantine new plants if possible to avoid introducing pests into your houseplant collection - it’s always easier to prevent an infestation than to remove an already-existing infestation. While your plant is isolated, check it regularly for signs of pests. It may take several weeks to ensure that a plant is completely pest-free.
QUESTIONS ABOUT LARVAE
WHAT DO THEY EAT? This depends on the exact type of Larvae, but they typically feed on the leaves of your plants, although they may also eat fruits or other parts of the plant. Others feed on fungi in the soil.
WHAT KIND OF BARRIER CAN I USE TO PREVENT THEM? In order to prevent an infestation from taking hold, it is sometimes effective to place a physical barrier around your plants to protect them. For instance, insect barrier fabric is a good way to prevent many different types of pests from damaging your plants.
HOW REGULARLY SHOULD I CHECK MY PLANT FOR LARVAE? If you want to be really diligent (and if your plants are outside) then it may be worth the trouble to quickly check your plants on a daily basis during the summer months. This is the easiest way to spot a new infestation threat early - therefore making it easier to prevent. However, if checking every day feels excessive, then around every 3-5 days should also be effective. The key is early treatment!
HOW LONG DO THEY LIVE? Larvae are actually part of a life stage that the majority of insects go through. As such, they are essentially young insects. How long this stage of the life cycle lasts depends on the exact type of insect, and can vary greatly, e.g. anything between 5 and 21 days for some types. They are a threat to plants as they must consume a lot of food in order to produce the energy needed to transition into their adult form.
