Sevin is labeled for weevils but does not exactly list black vine weevil. Talstar is labeled for treatment of weevils and many of our customers have cited success with Talstar for weevils. The product label calls for half an ounce per gallon of water, and this should be applied over 1000 square feet. There are not really any special instructions other then to cover all foliage completely including the base and trunks of the non-edible plants.
