Buy Do It Yourself Black-Vine Weevil Control, Professional Grade Black-Vine Weevil Killer Spray
The Black-Vine Weevil is a weevil that is notorious for the damage it causes in landscapes. Similar to other weevils, the black-vine weevil has a full metamorphosis life-cycle, and the larvae is the most damaging stage of the black-vine weevils life. The adult black-vine weevil feeds on leaf tissue and leaves notch shaped cutouts on leaves of the plants it feeds on, including rhododendrons, azaleas, and other woody ornamentals. While this feeding can cause some foliar damage, it is not harmful to plants long term, however the larvae can easily kill these same plants. While the adult feeds on leaves, the larvae of the black-vine weevil is a type of grub and feeds on the root systems of the same woody ornamentals the adult feeds on. As the larvae feeds, they can eat roots and girdle larger roots of plants, in effect cutting off the plants ability to take up water and nutrients. Often times, larval damage can go unnoticed until a plant has been totally decimated; significant feeding by larvae can result in plants that are able to easily be pulled from the ground with little effort and no root system left. When looking for how to control black-vine weevils, it is important to realize you may need multiple products. We highly recommend broad-spectrum insecticides with residual control as foliar sprays on your susceptible plants, particularly when notching of leaf tissue is visible. It is just as important to apply systemic insecticides to the root system of these plants, in order to protect your woody ornamentals and evergreens from root damage from the larvae. Preventative treatments are recommended when treating black-vine weevil, as significant larval damage is often left undiagnosed until the plant has been damaged to the point it needs to be replaced.
