Ants on your artichoke plant? Your leafy vegetables? Your house plants? They’re a prime indicator that sucking insects are feasting on your plants.
There’s a group of soft-bodied insects — aphids, mealybugs, soft scale and whiteflies that feed by sucking juices from plants. The direct damage they inflict on the plant can cause spotted, bleached, or curled foliage, and stunted growth. Indirect damage comes from the waste they produce. The pests can’t utilize all the sugar in the rich sap they draw from the plant, and excrete the excess in the form of honeydew, that looks just like drops of honey on foliage. That honeydew is a favorite of ants, and they will fiercely protect those soft-bodied producers, especially aphids, from predators, to keep that sugary stuff coming. Learn how to keep ants from crawling up your plants.
As outdoor temperatures get cooler, they may also start visiting you indoors seeking water, food, and shelter. If you find a trail of ants traipsing across your kitchen sink, use these methods for managing them. And if they’re really causing a problem, here’s information on more effective management indoors.
