How to Keep Your Plants Thrip Free

In greenhouses, interior plants and gardens, thrips are a prevalent pest.

Thrips wreak havoc on plants by sucking their juices and scraping at their fruits, flowers, and foliage. Fortunately, there are practical methods for getting rid of thrips and preventing infestations. This article will teach you how to recognize thrips as well as how to get rid of them.


Thrips are members of the Thysanoptera order.

They are little, sometimes winged, insects that are straw-colored or black.

Adult thrips are just about 2 mm long. They could have wings or not. The wings of winged thrips are fringed. They come in a variety of colors, ranging from yellow to brown to black. Thrips' mouthparts are asymmetrical, with one mandible being longer than the other.


Thrips overwinter as adults and pupae in the soil. Females lay their eggs in the tissues of flowers, leaves, and stems in the spring; each female can lay up to 80 eggs. Nymphs (wingless larvae) feed on plant sap after the eggs hatch. Before becoming adults, they go through one or more nymphal phases. In warm conditions, there may be 12 to 15 generations per year, with the full cycle from egg to adult taking less than 16 days.


Thrips dwell on and around the plants they eat. They're frequently discovered on the leaves, stems, and flower petals of your houseplants. Thrips harm plants by extracting important nutrients in liquid form from the plant with their syringe-like mandibles.


The easiest strategy to control thrips is to avoid an infestation. Here are a few ways to get rid of thrips before they do damage to your plants.


Keep your plant clean of debris. It will be easier to avoid an infestation if the number of areas where they can breed is reduced. Thrips lay eggs in slits cut in live plant leaves and stems, as well as any form of green foliage, therefore remove the plant detritus as soon as possible after trimming.

  1. Check your plants for damage and pest clusters where the leaves are linked to the stems.Take action as soon as you see an infestation.

  2. Look for signs of thrip damage on each plant you put into your home. Streaks, silvery speckling, and little white spots are all signs of thrips damage. If you notice any symptoms of damage, bag the affected plants and toss them in the garbage; do not add them to your compost pile.

  3. If an infestation has become out of hand, you will need to use a pesticide to control it. Make use of pyrethrin or another oil-based spray. To suffocate and poison thrips, this spray blends a pesticide with fatty oils.



If you have thrips on your plants but don't want to use an insecticide, here are some organic thrip management options.

Introduce predatory bugs: Thrips predatory mites, minute pirate bugs, and ladybugs are examples of insects that love eating thrips. Thrips are loved by Trichogramma wasps and lacewings, and they can help to control thrip populations.

Use an insecticidal soap made from natural ingredients: These are most effective against minor infestations. Make use of neem oil by combining it with some insecticidal soap for an added layer of deadly power that is also eco-friendly.
