What is a lerp insect?
Psyllids (jumping plant lice or lerp insects) are a common and diverse group of sap-sucking insects (Hemiptera. Psylloidea), related to whiteflies, aphids and scale insects. Most species appear to be host specific or confined to a group of closely related plants.
How do I get rid of lerp?
Oil and soap will kill some of the psyllid adults, eggs, and nymphs that are not covered by the lerps, and help to wash off honeydew. Oil and soap sprays are not highly effective against lerp psyllids and foliar spraying provides only temporary control.
What pesticide kills scale insects?
When the scale feed on the sap, they ingest the toxic insecticide and are killed. Acephate, imidacloprid and dinotefuran are three commonly used systemic insecticides that are effective against scale.
What does lerp look like?
Lerps are basically pure starch with some proteins and fats. They are white in colour, about 5mm in size and look like round, pointy hats. They are created by psyllids. Psyllids are tiny sap-sucking insects.
Can you eat lerp?

What does LERP look like?
What is the size of a lerp scale?
The lerp scale when fully formed in spring, is about 8 mm long, horn shaped and tapering from about 0.5 – 4 mm in width and is yellow to pale brown. Under each lerp scale there is an orange nymph which is active when the leaf is moved.
How many instars does a lerp have?
There are five instars each of which adds to the lerp, The last instars moves out from under the lerp before the adult emerges. Lerps insects are closely related with Scale Insects. Like Scale Insects, they are sap suckers and often aggregate in colonies.
Should I use systemic insecticides to treat scale damage?
Certain scale problems on large plants and hosts especially sensitive to scale damage may warrant the application of a systemic insecticide. If plants perform poorly or are repeatedly damaged by pests, the best course of action may be to replace the plant with a pest-resistant species or cultivar that is better adapted to the site conditions.
What are lerps made of?
Lerps are formed from the sugar and wax excreted by the insects. Those materials harden on contact with air to form the protection. Lerps vary in size, colour and shape. Each species has its own characteristic.
