What to Do About Pests that Can Harm Your Oregano Plants

By Bill Dugan, Executive Editor

Oregano with snails

Oregano with Snails

Are you encountering this dilemma with your oregano plants, where unwelcome visitors are leaving behind signs of distress on the leaves? If you’ve spotted irregular holes in your flavorful oregano, it’s likely the work of voracious pests. Protecting your oregano from garden invaders can be quite a challenge. Here are some common pests that enjoy indulging in oregano leaves:

Slugs and snails

The notorious slugs and snails have a taste for oregano just as they do for basil. You’ll notice ragged holes on the oregano leaves, especially after a rain shower, which is when these slimy creatures emerge to feast on your fragrant oregano.

To keep slugs and snails at bay, you can experiment with natural remedies. Consider setting up beer traps around your oregano plants, as these pests are attracted to beer. Place a small container of beer on the ground, and they’ll be lured in for a sip, ultimately meeting their watery end.

Japanese beetles

Japanese beetles can also be culprits responsible for decimating your oregano leaves. These shiny green and copper-colored insects are most active during the summer months, particularly in June and July. If Japanese beetles are the issue, you’ll notice that only the larger veins of the oregano foliage remain intact.

To combat Japanese beetles, try using essential oils like neem or cedar oil for sprays. Another option is to employ a household dust-buster to swiftly eliminate large beetle invasions.

Tiny insects like aphids

Aphids and similar soft-bodied insects might take a liking to your oregano plants. These pests are challenging to spot since they are minuscule and tend to hide on the underside of the leaves.

If aphids are plaguing your oregano, consider using a soapy spray on the plant leaves to deter them. Alternatively, you can introduce aphid predators like ladybugs, which have a penchant for aphids but leave your oregano unharmed.

Leafhoppers

Leafhoppers are yet another pest that enjoys feasting on oregano. Both adult leafhoppers and their nymphs can damage your oregano leaves by puncturing the undersides. Prompt action is necessary, as leafhoppers also release a watery saliva that can further harm your entire garden. Here are a few effective organic methods to tackle leafhoppers:

  1. Create a solution by mixing 1 tablespoon of rubbing alcohol with 1 quart of liquid soap to enhance the soap’s efficacy. Spray this mixture directly on the tops and bottoms of the affected leaves.
  2. Employ sticky traps or double-sided tape around the affected oregano plants, allowing these traps to capture the pests.
  3. For a more comprehensive capture, shake your plants vigorously to dislodge the adult leafhoppers. Many will become ensnared in the sticky traps as they attempt to escape.

Do you encounter yearly battles with pests attacking your oregano plants? We’d love to hear about your strategies for removing and preventing them. Please share your tried-and-true methods for safeguarding your oregano from these garden intruders.
