Distressed palm trees are most vulnerable to this damaging insect which makes transplanted and environmentally stressed palms more susceptible to attack. Mass trapping has been used to reduce Red Palm Weevil densities. The weevil larvae spend their entire four-month life cycle within the palm tree's trunk, hollowing it out from the inside until the tree dies.
