USDA Factsheet. How to control red palm weevil involves using systemic insecticides through trunk injections or soil applications. Since red palm weevil larvae spend much of their lives inside the tissue of a palm, finding tunnels or frass (wood shavings) on the crown of the palms central growing point is usually how your local arborist will be able to detect the presence of these pests.

Dieback in the apical (newest, uppermost, or center) leaves in the canopy is a common symptom of larval damage to the meristem tissue and should be investigated for RPW. Developing a pesticide treatment program should be made in consultation with a professional arborist, and two or more applications per year may be needed in infested areas to protect palms from weevil attack. Heavy larval infestations in this region can result in crown collapse and palm mortality. Monitoring for Red Palm Weevil Populations in California:In response to the RPW collection in Laguna Beach, state and federal survey crews deployed pheromone baited traps. In nature, adult weevils tend to fly during daylight hours and some studies suggest that they may only fly 1 mile over the course of a day. Feeding by weevil larvae in the crown of palm trees, causes significant damage that may result in the death of meristematic tissues.
