3 Ways On How To Get Rid Of Thrips On Houseplants

Do you know how to get rid of thrips on houseplants in 3 best ways? Isolation and rinsing, insecticides, and sticky traps should help eradicate this problem on your beloved houseplants. You can also use a greenhouse for the plants since pest management is more comfortable in a controlled environment.

However, we still want to keep bugs out of the greenhouse, and infestations can happen even to the most careful gardener. With thrips being tiny, it can be challenging to spot them until the signs show. Therefore, you must address the insects as soon as possible unless you have predatory insects already in the garden to do the work for you

The chances of having predatory mites and minute pirate bugs naturally existing in your garden or greenhouse is slim, so it’s best to learn the three techniques below. 

3 Ways On How To Get Rid Of Thrips On Houseplants

How To Get Rid Of Thrips On Houseplants Successfully


Isolation and rinsing of plants

The best way to get rid and perhaps even prevent thrips infestation is isolation and rinsing of infected houseplants. You can use this approach in addition to insecticides and sticky traps; after all, sanitation is an essential part of thrips management. For isolation, a simple mesh screen to isolate the infected area can restrict the pests’ movement.

You can also dedicate a quarantine area for new plants and materials before putting them inside. Remember that the new plants and those exposed to them can be potentially harboring thrips. Some gardeners even recommend rinsing the plant, particularly the leaves and their undersides. 

You can use a mild liquid soap to kill the thrips in the process and keep the population of pests more manageable. Just remember to be careful with the soap you’ll use towards your houseplants. And since we’re touching the topic of sanitation, always maintain cleanliness. 

You might be thinking that houseplants can skip certain management practices, but some can still have fallen debris that can increase the thrip population. Prevention is always easier than solving an infestation, so keep the area for your houseplants clean and make sure it has no entryways for thrips. 



The University of California Agricultural and Natural Resources mentioned precautions in using insecticides for thrips management. This is because of the potential injuries they can cause to the plants or beneficial insects. And depending on the time you applied the insecticide, the thrips might already be gone, or it’s too late to prevent damage like virus transmission. 

You want to use insecticides responsibly and avoid common mistakes like improper spraying, timing, and wrong target points. You might even need to check the active ingredients first to know when they’ll be effective best or if you’ll need a professional for applying the insecticide. But generally speaking, avoid acephate, organophosphate, or pyrethroids because of the risks of mite outbreaks and contamination of the environment. 

A safer insecticide would be something organic that you can spray directly on the leaves. Insecticidal organic soaps would not have any risk of residues compared to more potent chemicals. However, it’s still best to test spray on a few leaves before treating the houseplant thoroughly.

Do you want a more natural approach? Besides organic soaps, neem oil and hot pepper wax spray are also fair considerations for thrip control. Thrips that feed on oil-covered leaves will die like the insects that directly contact them. 


Sticky traps

Michigan State University recommends sticky traps for managing thrips. You can place yellow sticky traps among your houseplants, and they should capture adult thrips. However, this will only be effective if the traps are above the canopy since adult thrips can fly. 

Besides potentially lowering the thrip population, using sticky traps is also an excellent way to detect thrips if you’re suspecting their presence. 


Signs Of Thrips On Houseplants

The University of Georgia mentioned symptoms that you could check to indicate thrips’ presence on your houseplants. For example, the surface of affected plant parts is silver-specked due to the digestive enzymes and feeding mechanism of thrips that breaks the surface. 

You may also find the insects’ excrement in the form of tiny black specks. And if there is a black sooty mold, it might be due to the honeydew that thrips tend to excrete. Other signs of thrips include discoloration, shedding, and drying of fruits, buds, flowers, and leaves.

Over time, abnormalities in growth will lead to contortion and deformation, especially on the growing points. When can you find thrips? You’ll commonly find thrips on leaves and flowers, but younger thrips can drop on soil too. 



Thrips may be one of the tiniest insects, but they can do significant damage to your plants. You must know how to get rid of thrips on houseplants to control their population, prevent them from occurring again and salvage other plants. Isolation and rinsing of plants, insecticides, and sticky traps are three solutions that you can do together to create an effective thrip management system. 

Proper sanitation and quarantine in your area should help prevent thrips from getting to your houseplants. You must also be on the lookout for thrip infestation signs such as specks on leaves and then use sticky traps to confirm if the insects are present. If rinsing the plants or existing predatory insects haven’t solved the problem, you can opt for an organic insecticide safe for your plants and the environment.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
