Dew plants, also known as sundews, are carnivorous plants that are commonly used as houseplants. They are named after the droplets of dew that appear on their leaves, which attract and trap insects. However, what do you do when you notice little bugs on your dew plant? In this article, we will explore what those little bugs could be and how to get rid of them.
Identifying the Bugs
There are different types of little bugs that can infest dew plants. The most common ones include:
1. Aphids
Aphids are small, pear-shaped insects that come in different colors including green, yellow, and black. They are usually found on the undersides of leaves and can reproduce quickly, leading to a widespread infestation. They feed on the sap of the plant and can cause deformities and discoloration.
2. Spider Mites
Spider mites are tiny insects that often go unnoticed until they cause significant damage to the plant. They are usually found on the undersides of leaves and spin webs around the leaves and stems. Their feeding causes yellowing and browning of leaves.
3. Fungus Gnats
Fungus gnats are small black flies that hover around the plant. Their larvae live in moist soil, feeding on decaying organic matter and roots. They can cause root damage leading to stunted growth and wilting.
4. Scale Insects
Scale insects are tiny insects that attach themselves to the stems or leaves of the plant. They secrete a waxy substance that covers their body, making them appear like tiny bumps on the plant. Their feeding can cause yellowing and wilting of leaves.
Getting Rid of the Bugs
Now that we have identified the little bugs that can infest dew plants, how do we get rid of them? Here are some methods you can use:
1. Insecticidal Soap
Insecticidal soap is a natural insecticide made from potassium salts and fatty acids. It is effective in killing aphids, spider mites, and scale insects. You can buy a ready-to-use insecticidal soap or make your own by mixing one tablespoon of dish soap with one quart of water.
2. Neem Oil
Neem oil is a natural insecticide that is effective against a wide range of pests including aphids, spider mites, and fungus gnats. It works by disrupting the insect’s hormonal system, leading to their death. You can buy neem oil or make your own by soaking neem leaves in water overnight and straining the mixture.
3. Sticky Traps
Sticky traps are yellow or blue sticky cards that attract flying insects like fungus gnats. They are coated with a sticky substance that traps the insects when they land on the card. You can place them around the plant to catch the flying bugs.
4. Mechanical Control
Mechanical control involves physically removing the insects from the plant. You can use a toothbrush or cotton swab dipped in alcohol to remove aphids and scale insects from the plant. For spider mites, you can use a strong jet of water to wash them off the plant.
FAQ

Chemical insecticides should be used as a last resort as they can harm beneficial insects and pollute the environment. If you must use them, follow the instructions carefully and avoid spraying when the plant is in bloom.
How often should I check my dew plant for bugs?
It is recommended that you check your dew plant for bugs at least once a week to catch any infestations early.

Yes, you should remove any infected leaves from your dew plant to prevent the spread of the infestation. Make sure to dispose of them properly.
Conclusion
Little bugs on your dew plant can be a nuisance, but with the right identification and treatment, you can get rid of them and keep your plant healthy. Remember to use natural methods first before resorting to chemical insecticides and to check your plant regularly for any signs of infestations.
