Wax plants, also known as Hoya plants, are popular houseplants that are loved for their attractive foliage and sweet-scented flowers. However, one common problem that many wax plant owners face is the presence of lerps. These tiny, white, waxy structures may seem harmless but can cause significant damage to the plant if left untreated. In this article, we will discuss what lerps are, why they are harmful to wax plants, and how to get rid of them.
Lerps are small, white, waxy structures that are formed by the larvae of psyllid insects. These insects lay their eggs on the leaves of wax plants, and when the larvae hatch, they begin to suck sap from the plant. As they feed, they produce a protective covering made of sugary secretions and wax that looks like small white bumps on the leaves.
Lerps can cause significant damage to wax plants if left untreated. The feeding activity of the psyllid larvae can weaken the plant and make it more susceptible to other pests and diseases. The waxy coating produced by the larvae can also attract other pests like ants, which can further damage the plant.
One effective way to get rid of lerps on wax plants is through manual removal. This involves using a soft-bristled brush or a cotton swab dipped in rubbing alcohol to gently remove the lerps from the leaves. Be sure to do this carefully so as not to damage the leaves or stems of the plant.
Another way to get rid of lerps is by spraying the affected areas with a strong stream of water. This will dislodge the lerps from the leaves and wash away any sugary residue left behind. Repeat this process regularly until all the lerps are gone.
Neem oil is a natural insecticide that can be used to control lerps on wax plants. Simply mix a few drops of neem oil with water and spray the affected areas. The oil will suffocate the psyllid larvae and prevent them from feeding on the plant.
Insecticidal soap is another effective option for controlling lerps on wax plants. Simply mix a few drops of insecticidal soap with water and spray the affected areas. The soap will dissolve the waxy coating produced by the larvae, making them vulnerable to dehydration.
A: No, lerps are not harmful to humans.
A: Yes, you can prevent lerps from infesting your wax plants by keeping them healthy and free from stress. This includes providing them with adequate sunlight, water, and nutrients.
A: It’s a good idea to check your wax plants regularly for signs of lerps, especially if you’ve had problems with them in the past. Check the undersides of leaves and along stems for small white bumps.
A: While chemical pesticides may be effective at controlling lerps, they can also harm beneficial insects and pollinators. It’s best to try natural methods like neem oil or insecticidal soap first before resorting to chemical pesticides.
