Thrips are small, frustrating insects that can cause destruction to your plants both indoors and out. If you’re reading this, chances are you already have them. This guide will show you how to get rid of thrips for good, with real steps that really do work. No fluff, no guesswork, just real thrips treatments for real problems with plants.
What Are Thrips? (And Why You Should Care)
Thrips are small, flying insects that suck fluids out of plant cells by piercing them. They can be overlooked with the naked eye and measure only around 1–2 millimeters in length but their damage can’t be. You may find that your plants appear unhealthy, distorted, or just plain struggling. If you don’t do something about thrips, they can quickly spread and infest numerous plants, exacerbating the issue.
These insects make themselves well at home in hot, arid environments and easily infest houseplants, garden vegetables, flowers, and even trees. The first step toward effective control is to realize that an infesting thrip insect is both persistent and highly mobile.
Spotting Thrips Damage Early
In order to prevent an infestation, you need to catch it early. Look out for these thrips damage:
- Bronze or silvery streaks in petals and leaves
- Small, dark specks (thrip feces)
- Curled or distorted leaves
- Poor flowering or stunted growth
Thrips damage is easily confused with nutrient deficiencies as well as sunburn, so look carefully. Turn over leaves and magnify them if necessary. Examine newly emerged growth, where thrips congregate.
Thrip damage shows best on tender shoots. You can find thrip damage on plants such as flowers that don’t open or fruit that is scarred.
How to Treat Thrips – What to Do Immediately
After you have determined you have an infestation, act fast. Here’s how to control thrips with basic, available thrips treatments:
- Isolate affected plants to prevent the spread.
- Rinsing with water: One good blast of water (outside or showering plants indoors) can remove many of the insects.
- Insecticidal soap: Generally safe to use around plants and good at killing soft-bodied insects such as thrips. Spray thoroughly, particularly undersides of leaves.
- Neem oil: Both pesticide and thrip growth disruptor. Use as directed and spray at frequent intervals.
- Sticky traps: Blue or yellow traps can be used to capture adult thrips and measure progress.
Treat them again and again with consistency every 4–7 days at least every two weeks.
Organic and Chemical Thrips Control Methods
Depending upon how bad the infestation is, you can escalate your strategy to:
Organic Thrips Control Methods
- Predatory insects: Introduce beneficial insects such as lacewing or minute pirate bugs to prey on thrips.
- Diatomaceous earth: Sprinkle lightly around soil and foliage to kill thrips’ exoskeletons.
Chemical Thrips Control Methods
- Spinosad sprays: Spinosad is obtained from soil bacteria and is effective when applied judiciously, particularly to edible plants.
- Synthetic insecticides: Such insecticides can be highly effective but can damage pollinators and other useful insects.
No matter what method you use, be sure to rotate treatments when you’re using chemicals.
Long-Term Prevention and Plant Care
Treating thrips is just half the fight. Keeping them at bay long-term involves just a few good habits:
- Examine freshly procured plants prior to indoor introduction.
- Strong healthy plants can fight off disease and insects.
- Avoid excessive fertilizing, since it encourages sensitive new growth that attracts thrips.
- Apply reflective mulch or foil around plants to confuse and deter thrips.
- Neglect to clean and remove debris from soil regularly.
For houseplants as well, humid conditions can promote thrips to grow in arid environments. Make the environment less conducive by using a humidifier or pebble tray.
When It’s Time to Call in a Professional
If you have already tried several approaches and thrips continue to appear, or if infestation occurs in an extensive garden or plants of value, you may need to call in a professional pest control operator.
Expert assistance is particularly valuable in cultivating commercial produce or delicate plants such as citrus trees or orchids.
Final Thoughts: How to Get Rid of Thrips
Thrips can be frustrating, but they’re far from unstoppable. The solution to thrips control lies in moving quickly, using the proper thrips treatment, and consistency. Check your plants religiously, follow through carefully, and maintain preventative routines.
Whether you notice thrips leaf damage or just suspect your plant isn’t doing well, don’t wait. Act now.
Maintain sharpness and consistency and you will conquer the thrip fight.
