Do Bed Bugs Hate Lavender?

Lavender is an aromatic plant that has been found to offer numerous health benefits such as relieving chronic pain, alleviating stress, and reducing anxiety. Belonging to the mint family, lavender also freshens homes with pleasant fragrances that rid your house of other odors.

Although lavender is one of the most loved fragrant herbs by people, many bugs hate it! Ironically, insects such as fleas, mosquitoes, flies, moths, and bed bugs dislike the pleasant smell and aroma exuded by lavender.

On top of that, the lavender essential oil can be toxic. Though their toxicity is low for humans and animals, this essential oil can cause significant poisoning if ingested by small pests such as bed bugs. This is what makes lavender an effective bed bug repellent, killing them and their eggs.

So, do bed bugs hate lavender? Yes, bed bugs can’t stand the smell released by lavender and will move out of areas with lavender fragrance. As an added advantage, lavender also leaves you with a pleasant-smelling home.

Why Does Lavender Repel Bed Bugs?

For people who prefer natural pest control, lavender is the ideal option to make your home a bed bug-free zone. While no scientific studies have been done on lavender for bed bug control, its’ toxicity helps repel these creepy crawlies efficiently and effectively.

If ingested or sprayed directly on the pest, lavender will kill bed bugs on contact. But exactly what makes it such a good bed bug repellent? Lavender contains an active ingredient (terpene) known as linalool.

Linalool is a chemical compound that gives many plants, such as cannabis, mint, basil, and thyme, their pungent smell and aroma. It has also been found to repel nuisance pests. But why is lavender considered the most effective repellent of aromatic plants? That’s because it possesses a very high concentration of linalool.

Lavender efficacy against bed bugs has been backed up by anecdotal evidence. According to a study published in the Journal of Economic Entomology, essential oils can effectively kill bed bugs upon contact. Further evidence has found that commercially available essential oil sprays are highly effective against bed bugs on contact.

Can You Rely On Lavender as A Bed Bug Control Method?

Although lavender can help repel and kill bed bugs and bed bug eggs, it cannot be a replacement for professional bed bug control services. Entomologists recommend applying the treatment to problem areas for effective pest control. Multiple studies have shown that while essential oils effectively kill bed bugs, the impact is greatest when sprayed directly on the pest.

The problem is that bed bugs are nocturnal pests, meaning that they are mainly active at night. In addition, these nuisances are perfect hiders, often found in the tiny cracks and crevices on beds and furniture.

Bed bugs also have a well-developed sense of smell, which they use when seeking out human blood. So, if they detect a toxic smell, they will head in the opposite direction. For these reasons, you must thoroughly apply the repellent in every bed bug-infested area and places they might escape to in order to ensure complete control. But this is one of those things that are easier said than done.


Does Lavender Kill Bed Bugs?

As mentioned above, lavender oil can be toxic enough to kill bed bugs and bed bug eggs. However, it must come in direct contact with the bugs in order to kill them. Hence, you must ensure direct application. For instance, you can keep a spray bottle with lavender oil beside your bed and apply it directly to the bugs when you see them. Not only will lavender spray kill bed bugs but also deter them from your bed.
