Earwigs are common pests that are often found in gardens. These insects are known for their pincers and the damage they can do to plants. Many gardeners turn to natural remedies to repel earwigs, and one of the most popular options is geranium.

What is Geranium?

Geranium is a flowering plant that is native to South Africa. It is commonly used in gardens for its bright and colorful flowers, as well as its ability to repel pests. Geranium oil is also extracted from the plant and is used for various purposes, such as in perfumes and aromatherapy.

How Geranium Oil is Extracted

The oil is extracted from the leaves of the plant through steam distillation. The resulting oil has a sweet, floral scent and is known for its many benefits, such as its anti-inflammatory and antibacterial properties.

The Science behind Geranium and Earwig Repellent

The properties of geranium that make it an effective repellent for earwigs are still being studied. However, it is believed that the scent of geranium oil is what repels these insects. Earwigs have a strong sense of smell, and the scent of geranium oil overwhelms their senses, making it difficult for them to locate their prey or find their way back to their hiding places.

Studies on Geranium’s Effectiveness

Several studies have been conducted on the effectiveness of geranium as an earwig repellent. One study found that when geranium oil was applied to plants, it significantly reduced earwig damage compared to untreated plants. Another study found that planting geraniums around vegetable crops reduced earwig populations by up to 75%.

How to Use Geranium as an Earwig Repellent

There are several ways to use geranium to repel earwigs:

  1. Planting geraniums in your garden: Planting geraniums around your garden can help repel earwigs. You can also plant them near your vegetable crops to protect them from damage.
  2. Using geranium oil: You can apply a few drops of geranium oil onto a cotton ball and place it in areas where earwigs are likely to hide. This can include cracks in walls or around plants that are vulnerable to earwig damage.
  3. Making a spray: You can make a natural repellent spray by mixing a few drops of geranium oil with water and spraying it on plants or areas where earwigs are present.

To effectively use geranium as an earwig repellent, it’s important to use high-quality oil and apply it regularly. The scent of the oil will dissipate over time, so you’ll need to reapply it every few days to keep the repellent effect strong.

Other Natural Earwig Repellents

In addition to geranium, there are other natural remedies that can be used to repel earwigs:

  • Diatomaceous earth: This is a natural powder made from fossilized algae that can be sprinkled around plants or areas where earwigs are present. It works by dehydrating the insects and causing them to die.
  • Boric acid: This is a natural powder that can be sprinkled around plants or areas where earwigs are present. It works by damaging the insect’s exoskeleton and causing them to die.
  • Cedarwood: Cedarwood chips or oil can be used around plants or areas where earwigs are present. The scent of cedarwood overwhelms the senses of insects, making it difficult for them to locate their prey or find their way back to their hiding places.

While these remedies may be effective at repelling earwigs, they may not be as potent as using geranium oil. It’s important to test different remedies and find what works best for your garden.

Conclusion

In conclusion, geranium can be an effective natural remedy for repelling earwigs in your garden. Its scent overwhelms the senses of these insects, making it difficult for them to locate their prey or find their way back to their hiding places. Other natural remedies such as diatomaceous earth and cedarwood may also be effective but may not have the same potency as geranium oil. By using these natural remedies, you can protect your garden from damage without resorting to harmful chemicals.
