How to Protect Your Lawn Against Mealybugs

What are Mealybugs? 

Mealybugs are small, soft-bodied insects belonging to the Pseudococcidae family. They are common pests in Australian lawns, feeding on plant sap and secreting a white, waxy substance that protects them and can resemble cotton or mould. Mealybugs can weaken grass and create unsightly patches if left unmanaged.

How to Identify Mealybugs

“Identifying mealybugs is crucial for effective control.”

Mealybugs appear as small, oval-shaped insects covered in a white, powdery wax. They typically cluster together on grass where the leaf blade meets the stem, or near the soil surface. Their presence may also be accompanied by sticky honeydew secretions and sooty mold growth.

How to Control Mealybugs in your Lawn 

1. Regular Inspection and Monitoring

“Regular inspection of your lawn is key to early detection of mealybug infestations.” 

Routinely check grass blades, stems, and soil for signs of mealybugs, particularly in areas prone to moisture or shade.

2. Insecticide Treatments 

“Selective insecticides can be effective in controlling mealybugs.”

Apply insecticides containing active ingredients such as imidacloprid or acetamiprid according to label instructions. Target areas where mealybugs are present and ensure thorough coverage for optimal results.

When to Apply Insecticides

“Insecticide application timing depends on mealybug activity and life cycle stages.”

“Early detection and treatment during periods of high mealybug activity, typically in warmer months, yield the best results.” The effectiveness of insecticides varies but generally lasts for several weeks to months, requiring periodic reapplication as needed.
