Pruning palm leaves should be done in December and January when the temperatures are at their lowest and the number of adult weevils flying around looking for new places to lay eggs is at a minimum. The cut surfaces release kairomones attracting the weevils and also provide a nice easy surface for them to drill a hole for egg deposition. If you have leaves falling and causing a nuisance, perhaps in your drive or on the lawn, just trim the end, as far away from the trunk as possible, at least 1.5m -but the further the better. The area of exposed surface will be much less and if an egg is laid the chances are that the hatched larva won't ever reach the inside of the trunk.
