Hawaii's vast selection of tropical trees attracts a wide variety of pests, many of which can cause serious damage in a short time frame. While some are native, most are invasive species that threaten multiple species. From identification to effective tree service treatments, here's what you need to know about three of the most common Hawaii tree pests.

3 Common Hawaii Tree Pests & How to Handle Them

1. Pacific Beetle Cockroach

The Pacific beetle cockroach is a small, brown pest attracted to citrus and cypress trees. It looks similar to other species of roaches, so you're more likely to identify the damage it leaves behind—large sections of missing bark or dead foliage. Fortunately, insecticides are effective on cypress roaches, but schedule tree trimming beforehand to get rid of the damaged areas.

2. Papaya Mealybug

As the name suggests, they’re fans of papaya trees, but they also enjoy hibiscus, plumeria, and citrus trees. Their toxic injection damages tree production and causes honeydew growth.

To get rid of a papaya mealybug problem, you need to utilize a variety of landscaping and tree services. Prune the plant to remove all affected areas, then use a pressurized hose to spray out all of the pests. Once removed, use a pesticide to keep them away.

3. Coconut Rhinoceros Beetle

The coconut rhinoceros beetle is another invasive species endangering Oahu's plant life. Discovered back in 2013, the pest pierces the top of trunks to feast on sap, stealing away precious nutrients from palm trees. They're also attracted to papayas, sugarcane, and pineapple trees. Hire professional tree services to remove all dead trees and foliage to eliminate beetle nesting locations. If the pest is already present, hang breed-specific traps to reduce the population.
