Larvacidal drenches may be used to kill larvae but are of limited effectiveness with adults. Foliar sprays are very effective at controlling adult weevils when leaf notching starts but sprays must be repeated until no adults emerge. Orthene gives good control when applied as a foliar spray and drench. Foliar sprays must be repeated until no adults emerge. Orthene gives good control when applied as a foliar spray and drench. Since weevils can't fly and spend part of each day in the soil or mulch and part of each day feeding, you can also paint the trunks with Tanglefoot to stop them, but make sure no branches are touching the ground. Some people report that keeping the mulch layer away from the trunk reduces (does not eliminate) weevil damage IF they make sure that no branches touch the ground.
