When Acree returns home with a fresh plant, she immediately disposes of any pests by placing it in the bathtub. She tops the soil with pet- and kid-safe food-grade diatomaceous earth powder, which dries out the insects and their larvae, after lightly misting them with a natural DIY bug repellent that you can prepare with 1 tablespoon of tea tree oil and 1 cup of water.
Spray your plants
Making an insecticidal soap to spray on your plants is your best option if you’re dealing with soft-bodied pests like mealybugs, aphids, whiteflies, and spider mites. While you may purchase one at the shop, it’s simple to make a DIY version with organic ingredients. Simply combine 1 Tbsp liquid dish soap (free of bleach, degreaser, synthetic colours, and scents), 1/4 cup vegetable oil, and 1 Tbsp liquid dish soap in a spray bottle, then top it off with warm water and shake. Once a week, you can spray your plants with the combination to get rid of pest problems.
Dry out your plants
By simply eliminating the moisture, pests like fungus gnats that prefer damp soil in houseplants can be controlled. (Excuse me, gnats.) The best course of action in these types of circumstances, according to Susan Spanger, a professional gardener and floral designer at Bloomful Floral Design, is to water your plants less frequently than usual in order to let the top few inches of soil totally dry up.
You eliminate the source of food for fungus gnats—fungi in the soil—by not maintaining damp soil. The Sill claims that by letting it dry up, that important food source will be eliminated, which will also eliminate the fungus gnats. According to Spanger, you can also cover the top of your soil with a half-inch of sand. She claims that mature fungus gnats find the rough surface unpleasant and that it dries off soon. Those pests on the houseplants will never return.
How do you get pests out of indoor plants?
These are the tiniest, pearshape insects that you have undoubtedly seen in the vegetable patch outside. They can be found on indoor plants as well, and they tend to congregate around developing leaves and flower buds. They produce a gooey fluid known as honeydew after sucking the plant’s sap.
Remove any areas of the plant that are seriously affected to get rid of the bugs. Use a damp cloth to remove insects from other places, or use the bathtub to spray them with water. A cotton swab dipped in rubbing alcohol, vegetable oil, or insecticidal soap can also be used to remove them. Weekly removal should continue until they are gone.
What are the little insects on my indoor plants?
Fungus gnats are by far the most prevalent types of houseplant insects (also known as soil gnats). They are those bothersome little black gnats that you often notice crawling in the dirt and flying about houseplants.
They can be particularly challenging to manage because they breed and live in potting soil.
Identification: Tiny white worms in the soil, black bugs crawling on top of the dirt, and/or small gnats hovering about indoor plants.
Fortunately, fungus gnats only bother healthy indoor plants occasionally and do not do much damage. But they do consume roots. Therefore, extremely huge populations may harm young or fragile houseplants.
How can bugs in potting soil be eliminated?
How Can I Naturally Get Rid of Bugs in the Soil of a House Plant?
- Use a three percent hydrogen peroxide solution in water to thoroughly water the plants.
- Add some diatomaceous earth to the soil’s surface and the saucer of the pot.
- Put the plants somewhere well-ventilated, and let the soil dry up entirely.
Can I use vinegar spray on my indoor plants?
According to the Alley Cat Allies website, white vinegar has a potent, repulsive smell and taste that can effectively keep cats away from sections of your home that you don’t want them to enter. Despite being harmless to humans and cats, vinegar is deadly to plants due to its 5% acetic acid content. According to the Northwest Center for Alternatives to Pesticides, spraying vinegar on houseplant leaves will damage their cell membranes. As a result, the leaves are destroyed, and if the vinegar seeps into the plant’s soil, it will kill it by drying up the roots.
What can you apply to plants as a spray to deter insects?
There is no quick fix to keep insect pests away from your indoor plants and garden. I’ve picked up a few tips over the years on how to deal with bugs without using harmful chemicals. Here are some of my suggestions, including some homemade insecticides (soap sprays).
Pay Attention to Your Plants
Consider the following methods to deter insect pests from attacking your plants before using pesticides, even natural ones:
- Use organic fertilizers like aged compost to feed your plants. Strong plants are less likely to be attracted by insects and are better able to survive their attack than weak ones. If you’re using fertilizer, pay strict attention to the directions. Pests will be drawn to overfertilized plants and consume their lush new growth.
- Use companion planting to naturally ward off insects. While some plants coexist well, others do not. Take a look at our companion planting guide.
- To prevent pests from damaging your plants, especially sensitive transplants, use barriers like row covers. When plants are established and in flower, remove the coverings to allow insect pollination. Additionally, placing “collars” made of cardboard from toilet paper or paper towel rolls around the tiny transplants (1 to 2 inches into the soil) may stop pests like cutworms from eating the tender stems.
- Plantings should be timed to avoid bug population peaks. For instance, so as to avoid squash vine borers, which deposit their eggs in the early to mid-summer, sow squash as soon as feasible. To avoid the carrot fly, plant carrots after June 1 and harvest them by the beginning of September.
- Choose plants that have some pest resistance built in. Butternut squash is one of the vegetables I grow a lot since it is quite hardy against the squash vine borer.
- By controlling the bugs they feed on, beneficial insects will do a lot of the work for you if you make your garden inviting to them. For instance, lady beetles are a successful biological pest control for a variety of insects. Leave a tomato hornworm alone if you notice one with white cocoons on his back (see above photo). His body is covered with the eggs of a parasitic wasp, whose young will soon consume him from the inside out. An appropriate end for such a horrible pest!
- Recognize the bugs that inhabit your garden. If you don’t know who is a friend and who is an enemy, you can’t defeat them. To prevent them from becoming adults, become familiar with the appearance of their larvae and eggs.
These aphids have caused some harm, but if you notice black and orange ladybug larvae that resemble alligators attacking the aphids, don’t spray. He can consume up to 50 aphids per day, doing the grunt work for you.
Organic Pesticide Sprays for Insects
Avoid using harsh chemicals if you have tried all other options and feel you must use a spray. They will pollute the watershed, kill both good and bad bugs, and eventually the insects you are attempting to kill may develop a resistance to those poisons necessitating the employment of more stronger ones, which will do more harm than good. They may also cause harm to you, your kids, and animals and birds.
Making one of these homemade insecticidal sprays can help you take a more natural approach. Remember that although being less hazardous, they are not completely safe. Keep children and pets away from them. Before using them extensively, test them on a few leaves to ensure they won’t harm your plants. They will unquestionably cause foliar damage if you sprinkle them on your plants in the hot, sunny part of the day. When bees and other pollinators are not busy in the evening, spray.
- Dish Soap Spray: Mix 1 quart of water with 1 tablespoon of a mild liquid soap, such as castile soap or pure dish soap (no bleach, degreaser, or other additives). Although Dr. Bronner’s soap is pricey, it doesn’t contain any animal fats, making it a decent option for vegans. Soft-bodied insects can be easily killed using insecticidal soaps. Make sure to cover the entire plant, including the stems and both sides of the leaves. Sprays made of soap must be reapplied every 4–7 days or until you see a decline in population because they only operate when they are moist. If rain hasn’t done this for you after a few applications, spritz the plants with plain water to remove any soapy residue.
- Spray with oil: Combine 1 cup vegetable oil and 1 tablespoon mild liquid soap. Spray your plants as before using a quart of water and 2 to 8 teaspoons of this combination. This spray is good against aphids, thrips, mites, and scale because the oil smothers the insects.
- Insecticide from Tomato Leaves: Tomato leaves contain the insecticides solanine and tomatine. 2 cups of fresh leaves should be overnight soaked in 1 quart of water. Spray after sifting. In addition to killing aphids and many eating insects, it also draws helpful insects. Because it may transfer illness from plant to plant, avoid using it on other nightshades like potatoes, eggplants, or peppers.
- Contrary to what you may have read, garlic serves more as a repellant than a killer. Let 2 garlic bulbs and 1 cup of water be pureed overnight. Pour the liquid through a strainer into a quart jar, then top it out with water by adding 1/2 cup vegetable oil, 1 teaspoon liquid soap, and the remaining liquid. Fill a 1-quart sprayer with water, add one cup, and spray the damaged plants. Aphids, cabbage worms, leaf hoppers, squash bugs, and whiteflies can all be repelled by it.
- Hot pepper repellent spray: Hot pepper works effectively on a variety of insects as well as rabbits and deer. Combine 1 quart of water, 1 teaspoon of mild soap, and 1 tablespoon of dried chile powder. Spray the plants being attacked at full vigor.
If you have a lot of hot peppers blooming in your yard, purée 1/2 cup of the chopped peppers with 1 cup of water to create a new mixture. 1 quart of water with the puree added should be brought to a boil. Strain after allowing to cool. Add 1 teaspoon of mild soap, then spray plants at maximum strength. When using this spray, you might wish to wear gloves and avoid getting it in your eyes.
Many other plants, such as hyssop, lettuce leaves, onions, pennyroyal, peppermint, and radish leaves, have also been said to have insecticidal properties.
In terms of pest management, there is no one solution that works for everyone. At most, we can work to keep a good balance between the good guys and the evil guys while still procuring some good produce for ourselves.
Let’s take on weeds now that we know how to reduce insect problems. These weed-control suggestions include 5 Homemade Herbicides.
What kind of insects infest indoor plants?
Most homes have a warm, stable temperature, which is excellent for quick pest reproduction. Additionally, if ladybugs, parasitic wasps, and other beneficial insects aren’t present in your home to keep pests in control, houseplant insect pests can quickly grow from a minor problem to a full-blown infestation. Here are the top five types of houseplant bugs and what you can do to prevent them.
Infected gnats:
Adult fungus gnats are extremely bothersome. The typical illustration of a bothersome insect is these tiny black flies. When a plant that is infected is moved, a cloud of minuscule flies rises from the ground. Despite being a hassle, mature gnats only live for approximately a week and don’t harm your plants. The larvae, which primarily eat the fungi that naturally grows in potting soil, don’t either. Overwatering is typically the source of fungus gnat infestations since the eggs and larvae need water to live. In many cases, all that is required to eliminate this common houseplant pest is a simple reduction in watering. Beneficial nematodes put to the soil, though, will unquestionably solve the issue if that doesn’t work.
Scale:
Scale is one of the more difficult to detect varieties of houseplant bugs. The most prevalent houseplant pest scales are found on the undersides of leaves and along stems. There are many different kinds, each with a distinctive appearance. Scale insects frequently have a hard, shell-like covering that makes it challenging to identify and eradicate them. They can be fluffy, gray, black, or brown in color. If you notice a shiny glaze on the plant, examine it for scale because most scales leave behind the honeydew that I stated above. The most challenging pest to manage when it comes to houseplant bugs is scale. I like to use a special cotton pad that has been dipped in isopropyl rubbing alcohol to wipe them off my plants. The best control is achieved by repeatedly physically removing the insect from the plant over the period of a few weeks. But using a natural pesticide based on neem is also an option. Apply the plant outside or in a garage, and make sure to follow the label’s recommendations.
Whiteflies:
Only in southern locations is this common houseplant pest a problem because it cannot withstand the bitterly cold winters. But because they are sheltered from freezing temperatures indoors and can reproduce relatively quickly, whiteflies are among the most troublesome species of houseplant pests. Whitefly problems typically start with a plant acquired from an infested greenhouse, making a rigorous examination of any new plants all the more crucial. When disturbed, these tiny, white, moth-like flies will quickly fly off the plant. They are located on the undersides of leaves. Whitefly multiply so quickly that their sap-sucking habit can cause wilting, stunted development, and yellow foliage in plants. Yellow adhesive cards can be easily used to catch whiteflies by positioning them just over plant tops. Horticultural oil and insecticidal soap applications both work well. Try not to disturb the plant when applying, and be sure to cover both upper and lower leaf surfaces because all three of these treatments operate best when they come into direct touch with the insect pest.
Aphids:
Aphids may be little, but they may still be a huge nuisance. Aphids are the type of houseplant bug we’ve covered here that I find on my own indoor plants the most regularly. Aphids are tiny, teardrop-shaped insects that come in a variety of colors, including black, green, red, yellow, and brown. They occasionally have wings, but more frequently they are seen in groups on the undersides of leaves or fresh growth. Aphids, which have mouthparts that resemble needles and suck plant sap, stunt and distort plant growth. A soft, plant-friendly towel soaked in water can easily wipe off small infestations on plants, but as with all sorts of houseplant pests, when there is a significant infestation, additional treatments may be necessary. Horticultural oil or insecticidal soap are some organic pest control methods for controlling aphids. For optimal effects, make sure to apply these substances so they come into direct contact with the aphids themselves.
Arachnid mites:
There are numerous sorts of houseplant pests, but spider mites may have the largest populations “Heebie-jeebie potential. These aren’t really bugs at all, though. Instead, they are spiders’ close relatives. These microscopic pests that infest houseplants provide serious problems for both the plants and the homeowner who is dealing with the infestation. Even if you can hardly see them without a magnifying glass, once you realize that they are within your home, it is difficult to forget about them. Spider mites can collectively cover the entire plant with their delicate, silky webbing. The mites themselves can be seen as small dots creeping through the webbing if you look closely. There are a few things you may do to control this common houseplant pest before throwing away your spider mite-infested ivy or palm plant. Take the plant outside or into the shower to start with “With a water spray, remove it. Spider mites are little and are readily removed from plants with water. Make sure to rinse the top and bottom of the leaf. Then, once the plant has completely dried, cover them with a mild horticultural oil. For the greatest control, reapply the horticultural oil every 10 to 14 days for two additional applications.
These five kinds of houseplant bugs are by far the most prevalent, however there are a few other indoor plant pests that could occasionally cause issues. However, if you follow the five preventative procedures listed at the beginning of this article and make use of the mechanical and organic product controls advised, you should be able to prevent the majority of these tiny annoyances from posing any serious problems.
Remember that you can produce healthy, pest-free houseplants by arming yourself with a little knowledge. Be wise in the plants you choose. Apartment dwellers have a lot of wonderful plant options according to our list of the finest houseplants for compact spaces. Healthy indoor plants are also better able to repel pests. We’re confident that our primer on houseplant fertilizer will be very helpful to you as well.
