Bagworms have become the number one problem that needs to be controlled. I have raked all leaves, husk, and all other after harvest. I try to cut off all bag worms that can be reached (under 25') and spray the trees twice a year with Onslaught Insecticide with little soap.
For bagworm control, there is not an insecticide that will be effective once the bagworms are in their protective cocoons. You will need to treat in early summer before the bagworms are in this state for insecticides to work. You could use Fertilome Triple Action or Natural Guard Spinosad for bagworms on pecan trees in spring or summer. Keep in mind that Onslaught Insecticide cannot be used on pecan trees or other edible plants.
