The Unwelcome Visitor How To Deal With Thrips On Plants

Does your garden seem to be under attack by tiny, invisible insects? Have you found your plants covered in white spots or looking pale and weak? Chances are, you’re dealing with a standard garden pest: thrips. Thrips are small, slender insects that feed on plant matter and can quickly destroy your garden in a matter of days.

This article will explore different methods of identifying, preventing, and controlling thrips on plants. We’ll look at organic and chemical control options, as well as introducing beneficial predators to the garden and preventing further infestations in the future.


Identifying Thrips

Identifying thrips on your plants can be challenging, but with a bit of practice and knowledge, you’ll find it much more manageable. Thrips are tiny, pear-shaped insects that are usually less than 1/20 inch long. They can be brown, black, yellow, or white, depending on the species, and the adults have four long, narrow wings. When viewed under a microscope, thrips look like little hairs with legs.

The most apparent sign of thrips on plants is the presence of silver-colored specks or patches on the leaves and stems. This results from thrips feeding on plant cells and leaving behind their saliva, which can create spots of silver and gray on leaves. You may also notice small, dark, raised spots on the leaves undersides, which result from eggs being laid. Other signs of thrips on plants include distorted leaves, yellow or white patches, flower deformation, and wilting.

Thrips can be challenging to get rid of, but there are some natural methods you can try to help control the population. Planting flowers that attract natural predators like ladybugs, lacewings, and hoverflies can help reduce thrips populations. Additionally, using insecticidal soap or neem oil can help to reduce the number of thrips on your plants.

Preventative Measures

When preventing thrips on plants, the most important thing is to establish a defense before the insect shows up. This is done by creating and maintaining a healthy, thriving garden. Making sure your garden is free of weeds is a prime source of thriving for the thrips and is an essential first step. Additionally, reduce the number of stressed plants in your garden since they are more likely to be attractive to these pests.

To reduce the chances of an infestation, it’s also important to regularly inspect your plants and check for thrips. Early detection is critical in eradicating the pest, as they reproduce quickly and can cover a large area quickly. If you find any thrips on your plants, immediately apply a pesticide. However, it’s best to use an insecticide specifically for the thrips you’re dealing with, as individual species can resist different types of products.

It’s also essential to avoid the spread of thrips, such as avoiding overhead watering and frequent pruning. Finally, it’s best to rotate the plants in your garden to avoid the same plants being exposed to thrips for too long. Following these simple steps, you can keep your plants safe from these pesky pests.

Keeping Plants Away From Thrips

Thrips are unwelcome visitors in your garden and can cause significant harm to your plants. But, with a few precautions and proactive steps, you can keep them away from your plants.

Maintaining a Clean Environment

To correctly manage thrips and keep your plants healthy, it is essential to understand a few things about them. Thrips are small, slender, wedge-shaped insects ranging in color from black to yellow. Adult thrips feed on the young leaves of plants, where they extract fluids and suck out the juices. They may also feed on pollen.

One of the best ways to prevent and control thrips on plants is to check the plants for signs of their presence regularly. Some things to keep an eye out for include small clusters of white spots on the upper and lower surfaces of leaves, silver mottling on the surface of leaves, and silvery-white streaks on the stems. Additionally, you may find a tiny white moth-like insect flying around the plants. If any of these signs are present, you should take action to control the infestation. This can include insecticidal soap, horticultural oil, neem oil, or natural predators such as ladybugs and lacewings.

Organic Control Techniques

One of the most effective ways to keep thrips away from your plants is to use natural insecticides. There are many options available on the market, and they work by using extracts from certain plants and herbs. Neem oil and pyrethrin-based insecticides are effective against thrips and pose no risk to beneficial insects, such as butterflies and honeybees.

Another way to control thrips is to use commercially available beneficial insects, such as lacewings, ladybugs, and predatory thrips. These predators feed on thrips and other soft-bodied insects, keeping them in check and preventing them from doing too much damage. This is particularly useful if you have a large garden or greenhouse with many different types of plants.

You can also use cultural controls to help prevent thrips from becoming established in the first place. Planting certain flowers and herbs that attract beneficial insects, such as marigolds, chives, and garlic, can help keep thrips away. Also, remove dead or dying plants from your garden, as these can attract and provide a breeding ground for thrips.

Introducing Beneficial Predators

Introducing beneficial predators is a natural and effective way to keep them at bay. These beneficial predators include lacewings, ladybugs, and predatory mites. They can help keep thrips populations in check, which is especially beneficial for plants in greenhouses or other areas where chemical pesticides are difficult to use.

Lacewings are natural predators of thrips and are often used for indoor and greenhouse control. They are small, delicate-looking insects that can effectively reduce pest populations. Ladybugs, also known as the multicolored Asian Lady Beetle, are plentiful and can consume large numbers of thrips. They are also great for controlling other pests, such as aphids, mealybugs, and scales. Finally, predatory mites are tiny insects that feed on thrips, making them an effective way to reduce thrips populations indoors.

Treating with Neem Oil

Neem oil is a naturally derived insect repellent, fungicide, and pesticide extracted from the neem tree’s seeds. This oil is safe for pets, humans, and the environment, making it an excellent choice for the home gardener.

When using neem oil, it is essential to remember that the plant should be treated regularly, as it does not provide long-term protection. To treat for thrips, a spray of neem oil should be applied to both the top and underside of leaves. For best results, the solution should be allowed to dry on the plants and reapplied every couple of weeks.

When applying the neem oil solution, it is essential to be sure that all areas of the plant are treated, as thrips prefer to hide in the crevices of the leaves. The solution should also be applied in the morning or evening, as applying during the midday can cause damage to the plants.

It may take several applications to see results, but neem oil is an effective and safe way to control pests on plants. With regular applications, the home gardener can enjoy a pest-free garden.


The best way to deal with thrips on plants is to take preventative measures. Start by making sure you avoid introducing them in the first place by selecting plants from reputable nurseries and inspecting your plants for signs of thrips before bringing them home. The next step is to clean up your environment, removing weeds and debris around your plants that may attract thrips and maintaining a well-balanced ecosystem. You can also introduce beneficial predators such as lacewings or ladybugs to control thrips populations or use an organic control technique such as insecticidal soap or neem oil to help deter them. If all else fails, you can always use a chemical control option like an insecticide or pesticide specifically formulated to get rid of thrips. No matter what route you go, the most important thing is to be proactive in handling pest problems before they get out of hand. Check your plants regularly and take the necessary steps to keep unwelcome visitors out.
