Here’s How It Works and Why Stink Bugs Hate It

Stink bugs are highly sensitive to strong smells, especially natural oils. Certain essential oils are known to act as repellents because they overwhelm the bugs’ senses, making them avoid areas where the oils have been sprayed. North Carolinians are mixing up DIY sprays that can be applied to the exterior of their homes, including around doors, windows, and cracks, preventing stink bugs from even getting close.

So, what oils are the most effective at keeping stink bugs at bay? Here are a few top contenders:

1. Peppermint Oil

  • Why It Works: The strong, fresh scent of peppermint oil is like kryptonite for stink bugs. Its sharp odor confuses and deters them from approaching your home.
  • How to Use It: Mix 10-15 drops of peppermint oil with 2 cups of water in a spray bottle. Shake well and spray around your front door, windows, and any cracks where stink bugs might sneak in. Reapply every few days for best results.

2. Tea Tree Oil

  • Why It Works: Tea tree oil has a strong, medicinal scent that bugs despise. It also contains natural compounds that can disrupt the nervous system of insects that come in contact with it.
  • How to Use It: Mix 10 drops of tea tree oil with water in a spray bottle and spritz it around your home’s entry points. Not only will it keep stink bugs out, but it may also deter spiders and ants.

3. Eucalyptus Oil

  • Why It Works: Known for its camphor-like aroma, eucalyptus oil is another scent stink bugs can’t stand. Plus, it’s a great option if you want a fresh, clean-smelling home.
  • How to Use It: Add 10-15 drops of eucalyptus oil to water in a spray bottle and apply it to doors, windows, and any other entryways. Refresh the spray after heavy rain or every few days.

4. Clove Oil

  • Why It Works: Clove oil contains eugenol, a compound with powerful insect-repelling properties. Its strong, spicy scent creates a natural barrier against stink bugs.
  • How to Use It: Combine 10 drops of clove oil with water and spray it around doors and windows. Be cautious with clove oil, as it can stain some surfaces, so always test it in a small area first.

5. Lavender Oil

  • Why It Works: Lavender oil, while calming to humans, is overwhelming to stink bugs. It disrupts their ability to navigate and keeps them from entering your home.
  • How to Use It: Add 10-15 drops of lavender oil to water and spray it around your doors and windows for a pleasant-smelling and pest-free home.
