6 Best Nesting Box Herbs For Natural Pest Repellent That Keep Mites Away
Protect your flock from mites with 6 key nesting box herbs. These aromatic plants serve as a natural pest repellent for a healthier, chemical-free coop.
Dealing with mites is one of those persistent chores that every chicken keeper faces sooner or later. You can go weeks with a clean coop, and then one day, you spot the tell-tale signs. The conventional wisdom often points you toward a tub of chemical dust, but I’ve found a better, more holistic way to manage these pests before they even start.

Why Natural Herbs Beat Chemical Dusts for Mites
Chemical dusts, like diatomaceous earth (DE) or permethrin, certainly have their place in a heavy infestation. But using them constantly as a preventative measure is a different story. These fine powders can cause respiratory issues for both you and your flock, and there’s always a nagging concern about what ends up in the eggs.

Herbs, on the other hand, work with your coop’s ecosystem, not against it. They act as repellents, making the nesting boxes an unpleasant place for mites and lice to settle in. The goal isn’t to create a sterile environment, but a healthy, resilient one. You can grow most of these herbs yourself, giving you a sustainable, free source of coop protection that also smells fantastic. It’s about prevention, not just reaction.
Munstead Lavender: A Calming Mite Repellent
Lavender is more than just a pretty scent. Its strong floral aroma is a powerful insect repellent, and it has the added benefit of being a calming agent for your hens. A relaxed hen is a better layer, and a less-stressed flock is generally a healthier one.
I prefer the ‘Munstead’ variety because it’s hardy and produces a ton of fragrant flower buds. You’ll want to harvest the flower stalks right before they fully open and hang them to dry. Once dried, simply strip the buds from the stem and sprinkle them liberally into the fresh bedding of your nesting boxes.
Peppermint (Mentha piperita): A Potent Pest Foe
If you want a heavy-hitter in your herbal arsenal, peppermint is it. The high concentration of menthol is what makes it so offensive to mites, lice, spiders, and even rodents. Its scent is sharp and penetrating, creating a protective barrier in the nest.
A word of warning: mints are notoriously invasive. Never plant them directly in your garden unless you want a peppermint field. Grow it in a container where you can control its spread. For coop use, harvest the leaves before the plant flowers, dry them completely, and crush them to release their potent oils before mixing into the bedding.
Pacific Beauty Calendula for Soothing Nests
Calendula is a fantastic dual-purpose herb for any chicken keeper. Its slightly sticky, resinous flowers are a known pest deterrent. But they also have wonderful anti-inflammatory and antibacterial properties, which can help soothe a hen’s skin if she’s been bothered by pests.
The ‘Pacific Beauty’ mix is a great choice, offering a range of yellow and orange flowers that are easy to grow from seed. You just harvest the flower heads and dry them whole. The dried petals add a beautiful splash of color to your nesting box blend and contribute to the overall health of your flock’s environment.
Wormwood (Artemisia): A Powerful but Potent Herb
Now we get into the really potent stuff. Wormwood has been used as an insect repellent for centuries, and for good reason—it works. It’s a powerful deterrent for mites, lice, and internal parasites.
However, this is an herb to be used with extreme caution and respect. Wormwood contains a compound called thujone, which can be toxic if ingested in large quantities. Use it very sparingly, always dried, and only as a small part of a larger herbal blend. Never let your chickens eat it fresh. It’s a powerful tool, but one that requires knowledge to use safely.
Common Tansy (Tanacetum vulgare) for Nests
Like wormwood, tansy is another traditional "strewing herb" with a long history of repelling pests. Its button-like yellow flowers and ferny leaves have a strong, camphor-like scent that insects despise. It’s particularly effective against ants and flies, in addition to mites.
Tansy also comes with a caution. It can be toxic if eaten in large amounts, so it should only be used dried and in moderation within your nesting box mix. Think of it and wormwood as the "special forces" of your herb blend—you only need a tiny amount to get the job done.
Spearmint (Mentha spicata): A Gentler Mint
If you find peppermint’s scent a bit too overpowering, spearmint is an excellent alternative. It contains less menthol but still packs enough of a punch to deter pests effectively. It provides the same benefits as peppermint but with a sweeter, milder aroma.
Just like its aggressive cousin, spearmint should be grown in a container to prevent it from taking over your garden. The preparation is the same: harvest, dry, and crush the leaves. It’s a great choice for bulking up the minty component of your blend without making it overwhelming.
Creating Your Own Custom Nesting Box Herb Blend
The real magic happens when you combine these herbs. You don’t need a rigid recipe, but a good rule of thumb is to create a base of gentle, fragrant herbs and add smaller amounts of the more potent ones. A good blend is about layers of scent and repellent properties.
Here’s a simple framework to start with:
- 3 parts "Base" Herbs: A mix of calendula and lavender. These are safe, smell great, and form the bulk of your blend.
- 1 part "Aromatic" Herbs: A mix of peppermint and/or spearmint. This adds the strong repellent scent.
- A tiny pinch of "Potent" Herbs: If you choose to use them, add a very small amount of dried wormwood or tansy.
Make sure all herbs are completely dry before mixing and storing them in an airtight container. A handful of this blend mixed into fresh shavings every time you clean the nesting boxes is all you need to keep them fresh, fragrant, and far less inviting to pests.
Ultimately, using herbs in your nesting boxes is about shifting your mindset from pest eradication to holistic flock management. It’s a small, proactive step that creates a healthier, more pleasant environment for your hens and a more sustainable routine for you. This approach doesn’t just keep mites away; it builds a better home for your flock.
