Trumpet vine (Campsis radicans), also called trumpet creeper, grows in U.S. Department of Agriculture plant hardiness zones 4 through 9. Trumpet vine grows to heights of 40 feet and will spread up to ten feet wide. Featuring bright red or orange blossoms in the summer, trumpet vine might grow to be the target of worms searching for a simple meal. Get rid of wormlike caterpillars and larvae that might lead to harm to the perennial vine by applying carbaryl dust to the plant.
Wear gloves, safety glasses and a dust mask for safety when working with carbaryl dust. Choose a time to use the dust once the wind is calm and there’s absolutely not any chance of rain.
Stand along one side of the trumpet vine. Hold the shaker container using the carbaryl dust and shake to employ an even film of dust to the trumpet vine plant. Pay special attention to areas of the plant using heavy infestations of worms.
Work your way across the trumpet vine, applying the carbaryl dust evenly. Monitor the trumpet vine for indicators of continued infestation from the worms. Make another application of the carbaryl dust in seven to ten days, if needed, to achieve complete control.
