What are Bronze Orange Bugs

The young stages or nymphs of bronze orange bug are initially green and hard to spot, as their colour closely matches the colour of citrus leaves. As they develop they turn bright orange and then mature to large dark brown bugs, approximately 25 mm long. All stages of the bronze orange bug feed on young leaf shoots and flower and fruit stalks.

WARNING: When disturbed the bugs orientate themselves so they can squirt an evil smelling chemical in their attackers direction. This chemical not only smells awful, it stains the skin and can cause a burning sensation if squirted in the eye. 


The bugs suck the sap from young shoots, fruit and flowers in spring and summer. This causes wilting of young shoots and flower stalks which generally turn black and shrivel. 


How to get rid of Bronze Orange Bugs

You can pick bronze orange bugs off by hand and drown them in a bucket of soapy water. Be sure to wear gloves and eye protection while doing this. Also spray citrus trees every 5 – 14 days with Yates® Nature's Way® Citrus & Ornamental Spray. The spray works via contact so it’s important to spray the bronze orange bugs directly. To spot the bugs, it helps to walk around the tree several times, looking from different angles, as the bugs are very effective at hiding.
