As a horticulturist with a passion for organic pest control, I've spent considerable time researching and experimenting with various plants that can deter pests like the Japanese beetle. Japanese beetles are known to be attracted to over 300 types of plants, but there are some that they tend to avoid. Here are a few plants that are believed to repel or at least deter these voracious insects:


1. Garlic - The strong smell of garlic can deter many pests, including Japanese beetles.

2. Marigolds - The vibrant flowers of marigolds are known to repel Japanese beetles, and they also attract beneficial insects.

3. Ageratum - This plant is said to have a scent that Japanese beetles find unappealing.

4. Fennel - Similar to dill and anise, fennel has a strong aroma that can help keep Japanese beetles at bay.

5. Tansy - This herb has a pungent smell that can repel a variety of pests, including Japanese beetles.

6. Basil - The scent of basil can be a deterrent to Japanese beetles, and it's a great addition to any garden.
7.
Dill - Dill's strong smell can help keep Japanese beetles away from your garden.
8.
Angelica - This plant has a scent that is not favored by Japanese beetles.

It's important to note that while these plants can help deter Japanese beetles, they may not completely prevent an infestation. A combination of strategies, including cultural controls, beneficial insects, and physical barriers, is often the most effective approach to managing these pests.
