AzaMax will control Weevils
AzaMax is a natural product with a broad spectrum of pest control and broad plant applications. AzaMax is an anti-feedant and insect growth regulator which control (kills) pests through starvation and growth disruption within two or three days. Therefore you use this product when the weevils are chomping away on your plant. Spray in the early evening to get them as they climb the shrub to eat. Any sprayer can be used to apply AzaMax.

Predatory Nematodes For Next Year's For Larvae
You use this approach a year after you have struggled with weevils on one or more landscape plants. They will have laid their eggs in the soil directly below the plant. Applying predatory nematodes is one of the best techniques for dealing with weevils which are always tough to control using a spray insecticide. Predatory nematodes will go down into the soil seeking out the larvae of the weevil, thus knocking them out before they even become adults able to eat the leaves of the landscape plant. Release them early in the season when the soil has warmed up; around planting time for tomato seedlings.
BENEFICIAL NEMATODES These microscopic insects will seek out and destroy over 230 kinds of soil dwelling and wood boring insects, including cutworms, armyworms, rootworms, weevils, grubs, fungus gnat larvae, and many more. They are completely safe for people, pets, and the environment, and are compatible with other beneficial insects. Beneficial nematodes are shipped live in the box and may be mixed directly into the soil and are applied with a sprayer.
USE: Beneficial Nematodes (BN) attack more than 230 kinds of soil dwelling and wood boring pests, such as flea larvae, white grubs, cutworms, corn root worms, strawberry weevils, gypsy moth larvae, cabbage root maggots, fungus gnat larvae, and many more. RELEASE: BN may be released by spraying with water, mixing with mulch and applying directly to the soil or potting mix, or injecting into burrows. They may be used any time of year, as long as the ground is not frozen. Do not release in direct sunlight, as this will kill them. See directions for details. COVERAGE: Will cover up to 200 square feet, but faster results are obtained with higher concentrations, covering only 200 square feet. GENERAL INFORMATION: Beneficial Nematodes (Steinernema feltiae) are microscopic in size and cannot be seen with the naked eye. But the 7 million active units in each pint container will hunt down, penetrate, and kill most soil dwelling pests. BN will attack over wintering adult insects, pupae, diapausing larvae, and grubs when they are in the soil, bark, or even ground litter. BN do not affect humans, animals, or plants. They are completely compatible with beneficial insects such as ladybugs, lacewings, and praying mantids and do not harm earthworms.
Diatomaceous Earth (D.E.) When Beetles Emerge In Spring
Diatomaceous earth (D.E.) is a fine powder that is made of crushed microsopic sea shells, creating very sharp edges that don’t hurt us, but do serious damage to the shell of the weevil. Dust D.E. around the base of the plant to create a barrier for the pest, or dust the whole plant with D.E. Dusting should progress upward from the ground, covering all stems and leaves, especially the undersides of leaves. Apply D.E. in late evening or at night, and predator insect destruction will be low.
