Ants 2

Malathion, a popular organophosphate insecticide, is commonly used in agricultural and residential settings to control a wide variety of insects. Among these insects are stink bugs. But does Malathion effectively eliminate these pesky creatures? Let’s delve into the subject.


Yes, Malathion, a broad-spectrum insecticide, is effective in killing stink bugs. It works by inhibiting the function of the insects’ nervous system, leading to their death. However, it’s crucial to follow the instructions and safety precautions on the product label for effective and safe use.

What is Malathion?

Before we answer the question at hand, it’s important to understand what Malathion is. Malathion is a broad-spectrum insecticide, which means it controls a variety of insects. It’s widely used in agriculture, residential landscaping, public recreation areas, and public health pest control programs. Besides stink bugs, Malathion is effective against pests on agricultural crops, stored products, golf courses, home gardens, and outdoor sites. It’s also used in public health mosquito control and fruit fly eradication programs.

How Does Malathion Work?

Malathion kills insects by inhibiting their nervous system’s function. It binds to the enzyme acetylcholinesterase (AChE) at nerve endings within the insects’ bodies. This enzyme breaks down the neurotransmitter acetylcholine, which is necessary for transmitting nerve signals. When Malathion inhibits AChE, acetylcholine accumulates at nerve junctions, causing overstimulation and eventual paralysis, leading to the insect’s death.

Is Malathion Effective Against Stink Bugs?

Malathion is indeed effective against stink bugs. It is labeled for stink bug control and has proven to be a successful method for controlling them when used as directed on the product label. For example, it was found to reduce damage caused by stink bugs on various crops, such as white cabbage and rice. However, it’s crucial to adhere to the instructions and safety precautions on the product label to ensure proper usage and effectiveness.

How to Use Malathion to Kill Stink Bugs

  1. Choose the appropriate Malathion product: Ensure the product is labeled for stink bug control.
  2. Dilute the Malathion concentrate: Follow the instructions on the product label for the correct dilution rate.
  3. Apply the spray: Spray the Malathion solution on the affected plants, focusing on areas where stink bugs are present or may rest.
  4. Follow safety precautions: Wear appropriate personal protective equipment and avoid contact with skin, eyes, and clothing.
  5. Monitor the effectiveness: Keep an eye on the stink bug population and reapply the Malathion spray as needed.

Risks and Precautions

While Malathion is an effective insecticide, it’s important to be aware of the potential risks and harms associated with its use. Malathion can cause harmful health effects if exposure occurs in high amounts. These effects can include difficulty breathing, chest tightness, vomiting, cramps, diarrhea, watery eyes, blurred vision, salivation, sweating, headaches, dizziness, loss of consciousness, and even death.

To minimize these risks, always follow proper handling procedures, wear appropriate protective equipment, and avoid consuming contaminated food.

Alternatives to Malathion

If you’re hesitant to use Malathion, there are several alternatives available for dealing with stink bugs. These alternatives include natural pyrethrins, deltamethrin, and even simple home remedies such as a combination of hot water, dish soap, and white vinegar.

In conclusion, while Malathion can effectively kill stink bugs, it’s important to understand the potential risks associated with its use. Always follow safety precautions and consider alternative methods when possible.
