How to Kill Spiders on Houseplants With Home Products
There’s typically no need to worry about spiders if you spot fine webbing on houseplant leaves. Your plant is likely hosting spider mites, tiny, eight-legged arachnids related to spiders, rather than hosting true spiders themselves. Spider mites are sap-sucking pests that commonly live in dense colonies beneath plant leaves. Their feeding activities can result in yellowed or stippled leaves that might fall from the plant prematurely. Fortunately, you can easily treat spider mite populations on houseplants with common dish soap and water.
Mix 3 tablespoons of liquid dish soap with 1 gallon of water. Pour the solution into a spray bottle.
Test the soap solution on a small, inconspicuous part of your houseplant. Wait one to two days and check the tested area for any type of injury. If no damage occurs, spray the solution on the rest of the foliage.
Spray your plant until you thoroughly cover the tops and undersides of leaves. Apply the solution where stems meet the stalk as well. Soap spray offers no residual effect, so thorough coverage increases your chances of directly spraying and killing the spider mite pests.
Rinse the soap solution off the leaves in about two or three hours. Removing the soap residue from foliage surfaces reduces the risk of leaf burn.
Repeat applications of the homemade soap spray every four to seven days until your houseplant becomes pest-free. Spider mites often require two or three treatments before you effectively reduce pest populations.
Things You Will Need
Liquid dish soap
1 gallon of water
Examine houseplants for tiny webbing every time you water. Spider mites are far easier to control if you find and treat the pests before their numbers increase high enough to damage plant tissue.
Soap products have been used for centuries to kill insects on plants. They kill many insects by disrupting outer cell membranes and some by dissolving the insect’s waxy outer layer, thus creating dehydration.
Avoid using dishwashing powders, laundry detergents and citrus-based dish soaps because they contain harsh chemicals that can quickly cause leaf burn.
Isolate mite-infested houseplants during treatment to prevent the pests from spreading to other plants in your home.
Always wash your hands after working with infested houseplants to prevent spreading the pests.
Discard houseplants that suffer with severe or chronic spider mite infestations. Although it might seem like a drastic move, it can help prevent your other plants from suffering the same fate.
