Once whiteflies make themselves at home, your indoor plants lose their healthy glow and end up with limp leaves and a sticky coating that no one wants to see. These tiny insects hide on the undersides of leaves and feed by piercing the plant tissue, slowly draining away its energy. They are among the types of bugs you don't want living in your home because they weaken your plant by feeding on it and leave behind honeydew, an excrement that can also form sooty mold, adding to the mess. But there's a safe and simple fix to keep your plants safe from whiteflies and that's by using insecticidal soap.
It works on contact, kills the pests quickly, and has less negative side effects to your plant, making it a reliable choice for your indoor space. With consistent use, you can stop infestations before they take over and bring back that lush, healthy look to your plants. But, before you start drenching your plants with this magic solution you need to make sure that you're doing it the right way and under the right conditions. Here's how you can get rid of these bugs on your indoor plants using insecticidal soap.

Insecticidal soap is one of the best ways to get rid of whiteflies, because unlike harsher sprays, it kills whiteflies on contact without leaving behind toxic residues. That means beneficial insects, such as ladybugs or lacewings, won't meet harm unless you've directly sprayed them by accident. The trick to combatting whiteflies is in getting the coverage right. Whiteflies tend to gather under leaves, especially the lower ones that are harder to reach. For insecticidal soap to work, you'll need to coat both sides of the leaves thoroughly. It may take more than one application, so don't be discouraged if you still see some bugs moving around afterward.
When you spray is just as important as how you spray. Insecticidal soaps work best when conditions allow them to dry slowly. Early morning or in the evening, when the sun isn't beating through windows, are the ideal times. Spraying in the middle of a hot afternoon isn't a great idea as it just leads to quick drying and poor results. Don't oversaturate your plant with the spray either. You want the leaves well-coated but not dripping. Even though insecticidal soaps and oils are considered less toxic, they're still chemicals. Always check the product label before you use it. You'll find details on how much to use, how often to reapply, and even what to do in case of accidental exposure.
If you've been battling whiteflies, you might be wishing for a natural shield that keeps them at bay. For that you can grow plants from the artemisia family. Artemisia includes familiar names such as mugwort, sagebrush, and wormwood. In fact, there are hundreds of different varieties, many with a reputation for being hardy and aromatic.
Their fragrance is strong and medicinal, often compared to an antiseptic scent. For insects like whiteflies, that smell is a major turnoff. The leaves of artemisia carry oils that make them fragrant, and bitter to taste. Whiteflies and other common pests find them unappealing, which is why gardeners often rely on them as natural pest deterrents. The beauty of Artemisia is that it repels pests without needing sprays or chemicals, all while fitting right into your indoor plant collection.
Other aromatic herbs such as basil, chives, and garlic are said to have strong smells and fragrances that deter whiteflies.
