A List of Plants that Repel Stink Bugs
1. Garlic
With their awful odor, stink bugs can’t seem to withstand strong smells, as we expect them to adapt to such naturally. Garlic, a common ingredient in many culinary, can be handy in repelling these bugs, because it will release a chemical that will keep pests away, because the smell of this chemical is uncomfortable to the bugs.
– Quantity Needed
You do not have to fill your garden with garlic plants and forget about planting what you had in mind.
A few garlic plants will do for this reason, as a few of them will release a chemical together that is strong enough. Nonetheless, you can plant them at the edges of your garden or as pot plants.
Other than planting garlic, you can take a few cloves and make garlic spray. You can boil the cloves in clean water and let the mixture cool. What you must do is strain and put the mixture in a spray bottle and spray on your plants and the entry points to repel the stink bugs.
Having these plants around helps keep the stink bugs away and provides a fresh ingredient to your cuisine.
2. Catnip
If you have seen or planted some catnip plants in your garden, you know how they make the cats go crazy about them.
This plant is also known as the Nepeta Cataria, and cats are usually the animals that love to chew and rub themselves against the plant. According to recent studies, these plants have a euphoric effect on cats; the more they rub, the better they feel.
Other than being used by felines, catnip has been used by communities for centuries as medicine to treat nearly all diseases before the introduction of modern medicine.
– Insect Repellant
Although humans and cats love the herb, the same thing does not apply to insects. It acts as a repellent, thanks to its strong scent that even the stink bugs are not fond of, and this is because of the scent that it releases.
Although plants naturally repel insects, but in this case, cats would also come in handy. As they rub themselves against the plant, the plant’s scent becomes more potent as more fluids get released from the damage that occurs from the rub. As a result, the stink bugs flee as they cannot stand the scent.
– Challenges
Catnips are sure to help get rid of most insects. However, they can attract stray cats to your compound to experience the magic they get from chewing and rubbing against the plant, and instead of surviving its purpose to get rid of the bugs, they will be diminished, and eventually they will be gone by the damage caused through stray cats.
The plant is also a fast spreader, and you must trim it frequently to avoid getting it out of control.

Thyme can withstand harsh climatic conditions, making it a great option for removing the stink bugs that come out when the temperatures start dropping. Plant a few thyme plants in the entry points you suspect, and you will never have to stress about dealing with these bugs.
