Types of plant pests

Changes in leaf color or texture can signal an insect problem. Leaves may become spotted, speckled or yellowed when insects are present. Leaves might also become distorted or misshapen, often looking cupped or pinched. You may spot webbing draped along leaf undersides or where leaves attach to stems.

Mild Soap Spray

Always use a mild soap when treating your houseplants. Add 1 tablespoon of dish soap into a 1-quart spray bottle. Fill with tap water. This mix is a 2 percent solution that can treat and control some bugs, such as aphids, mealybugs, and spider mites.

Apart from these, there are many other insect pests like Termites, Jassids, Leaf folder, Cabbage Diamond Black-moth, Leaf Roller, Red pumpkin beetle, Stem borer, etc. & noninsect pests like Root-knot nematodes, snails & slugs; all of them are equally harmful to your garden plants.

They include locusts, certain crickets (for example, the mole cricket), click beetles, darkling beetles, cutworms and related species of boring moths, and corn and gamma moths.

Nix Plant Pests

A 50-50 white vinegar and water solution repels insects such as midge flies. You can use it on plants and surfaces, such as patio tables and outdoor bar counters. Because of its acidity, always dilute white vinegar before spraying it on plants. Straight vinegar may damage or kill plants.

Many caterpillars, beetles, and especially earwigs and slugs, feed at night and hide during the day. Handpicking caterpillars, beetles and slugs and dropping them into soapy water can be effective in home vegetable gardens.

Soapy water can benefit plants, particularly in controlling certain insects, but it’s important to ensure that the soap product you use doesn’t have additives that are harmful to plants and that you dilute it sufficiently to avoid damage. Always test a small portion of the plant for tolerance to the chemicals.

Though vinegar can be fatal to many common plants, others, like rhododendrons, hydrangeas and gardenias, thrive on acidity which makes a bit of vinegar the best pick-me-up. Combine one cup of plain white vinegar with a gallon of water and use the next time you water these plants to see some amazing results.

Dawn liquid dish detergent in approximately a 2 percent concentration is a fairly safe alternative to commercial insecticidal soaps formulated to kill insects such as aphids, mites and scale on plants and keep them away.

Pour neem oil or insecticidal soap solution (natural treatment) on the top part of the houseplant soil and spray the area thoroughly. For Neem solution, use 2 tbsp Neem oil + 2-3 tsp mild liquid soap + 1 gallon of water. Neem spray will kill and repel gnats as well. Apply treatment once every week, for 2-3 weeks.

Very simply put, soil mites are beneficial arthropods (related to spiders and ticks) performing the very important task of helping breakdown organic matter such as leaf litter, fungus, algae, and other naturally occurring substances in the soil.

The term “plant pest“, mainly applied to insect micropredators of plants, has a specific definition in terms of the International Plant Protection Convention and phytosanitary measures worldwide. A pest is any species, strain or biotype of plant, animal, or pathogenic agent injurious to plants or plant products.

Vinegar is one of the best ingredients to make a pest control spray. Acidity of the vinegar is potent enough to eliminate many pests. Vinegar is often used as a contact type insecticide, which means that you need to spray it directly onto the spotted bug to make it effective.

Fungus gnats (also called soil gnats) are probably the most common (and annoying) houseplant pests. You will notice these indoor plant bugs crawling out of the potting soil, or flying around your plant when you water or otherwise disturb the soil.

You can get rid of the pesky insects by dabbing them lightly with a cotton swab dipped in 70 percent isopropyl alcohol (avoid touching delicate leaves) or spraying with a dish-detergent and water mixture (one teaspoon of soap to one gallon of water).

Solution 1: Mixing Hydrogen Peroxide with Your Water

This will eliminate any eggs or larvae living in the soil. This process will be most effective if you do this with all of your plants at once, so that any remaining gnats do not re-populate in other planters.

Brands like Miracle–Gro bagged soil have been found to sometimes contain small black flies, but the existence of these bugs in the soil is not that surprising. The little black bugs you found in your bag of Miracle–Gro soil are likely fungus gnats, which are known for infesting unsterilized soil.

Miracle–Gro supplies an enormous amount of nitrogen for plants so that they grow big, bushy, green, and fast. The problem with MG is that the nitrogen is derived from synthetic ammonium and water soluble nitrates, producing off-chemicals that are harmful to soil microbes, worms, and all other forms of life in the soil.
