Quick Questions

How long does one bag last?

Each bag keeps your coop fresh for up to 5 weeks. When the scent fades, sprinkle in the next one.

Is it safe for my chickens?

Yes. It is natural vermiculite with a hydrophobic coating, non-toxic and non-abrasive. The essential oils are microencapsulated, so they release slowly and stay off your birds, and the granules stay dry and non-clumping.

How many bags do I need?

It depends on your floor space. Each bag has 4 packs, and one pack freshens about 2×4 ft (8 sq ft) for a month. A 4×8 ft coop uses about 1 bag a month. Work it out for your coop.

Does it replace cleaning the coop?

No. It keeps a clean coop smelling fresh for longer between cleanouts. If the bedding is wet or dirty, change it first, then sprinkle in a fresh bag.

Does it work with deep litter?

Yes. One deep-litter keeper adds it each week when he turns the bedding. With chicks, he mixes it in and lets the bedding air out for an hour or two before they go in.

Can I mix scents?

Yes. Pick 1 to 4 bags and split them between Mint and Rosemary Thyme any way you like.

How does Subscribe & Save work?

The Problem

Signs Your Coop Needs A Refresh

Every backyard keeper knows these. Coop smell builds up fast between cleanouts, and it doesn't stay in the coop.

A keeper covering her nose at the coop door

That Smell When You Open The Door

That sharp, sour coop smell hits you before you've even collected the eggs.

The Smell Reaches The Patio

Backyard coops sit close to the house, and close to the neighbors too.

Stinky Nest Boxes

It's where your eggs are laid and where you reach in every single day.

A keeper hauling a wheelbarrow of old bedding

Mucking Out Again And Again

You change the bedding, and a few days later it smells like you never did. Then it's another bale and another afternoon.

The Solution

Meet Coop Refresher Sprinkle Once. Fresh For Weeks.

Natural vermiculite granules with essential oils sealed inside tiny capsules. Sprinkle it over the bedding and the scent releases slowly, day after day, for up to 5 weeks.

Slow-Release Scent
The essential oils sit in microcapsules that open a little at a time, so the coop smells fresh for up to 5 weeks per bag.
Dry, Non-Clumping Granules
A hydrophobic coating keeps the granules dry, so they don't turn to mush in damp bedding.
Non-Toxic, Non-Abrasive
Natural vermiculite, safe for hens and for you. The oils stay sealed in the granules, off your birds.
Made In The USA By GrubTerra
Caring for backyard flocks since 2019, with 100,000+ orders shipped to keepers across America.

Mint, Rosemary & Thyme Why These Herbs?

Keepers have tucked fresh herbs into nest boxes for generations. Coop Refresher gives you that garden scent, released slowly for weeks. A clean, herb-scented coop is a nicer place for hens to settle in at night and lay in the morning.

Mint: cool and clean

A crisp, cooling scent that cuts right through that barnyard smell. One keeper says you can smell it "from a good distance."

What researchers found: in a lab study on poultry red mites, spearmint oil repelled the mites during the first 2 days of testing. George et al., Veterinary Parasitology, 2009.

In our Mint scent

The studies tested the essential oils in a lab, not Coop Refresher. Coop Refresher is a coop deodorizer, not a pest treatment.

"This little packets pops a wonderful smell. I bet the girls felt like they were at the spa!!!!"

Brenda J., Verified Buyer

"Sprinkled Grubterra Chicken Coop Refresher in our coop with fresh bedding, and our entire flock immediately came in to investigate."

4 Things Coop Refresher Does For Your Coop. Every Day.

What's in the bag, and what keepers say it does.

Fresh For Up To 5 Weeks

Slow-release microcapsules

Sprays and powders smell strong for a day, then fade. Coop Refresher's oils are sealed in microcapsules that open a little at a time, so one bag keeps the coop fresh for up to 5 weeks.

A keeper says: "Four weeks later and the coop still smells great." – Dorothy B.

Stays Dry. Won't Clump.

Hydrophobic coating

Each granule is coated so water rolls off. It stays dry and loose in the bedding, so your bedding lasts longer between changes.

A keeper says: "The water resistant property is impressive! My egg boxes get pelted with rain and leaks in but I've seen less rain after this stuff!" – Valerie H.

Coop, Nest Boxes & Run

Just sprinkleNo sprays

No spray bottles, no mixing, no measuring. Sprinkle it on the coop floor, in the nest boxes or around the run, wherever the smell builds up, and it gets to work right away.

A keeper says: "As soon as we put one of the packets in the run and inside of the cook, within minutes, the bad smells were completely gone." – Zachary M.

Safe For Hens. Two Scents.

Non-toxicNon-abrasive

Natural vermiculite with the oils sealed inside, so the scent fills the coop, not your hens' feathers. Choose fresh Mint, Rosemary Thyme, or mix both in one box.

A keeper says: "It's natural, easy to use, and safe for the chickens, which is huge for US." – Dorothy B.

What Other Keepers Are Saying

Danielle G.

My coop has never smelled so good!

Christina R.

Mama was very comfy in the coop raising her chicks. The coop was fresh smelling with the Grub Terra Refresher!! Can't wait to try more from this brand with my flock.

Dee Dee

Our Feathered babies love a nice smelling coop sweet coop. Adding even a small amount makes their nesting boxes and floor smell so fresh and clean especially mid deep cleans and after a deep clean. Our birds thought it was food at first but all the products are safe even if they eat it which is as important as the smell. We've mixed this in even when we were lazy and didn't do a full clean and the coop still comes out smelling fresh and it lasts a long time. Even a little bit lasts a long time. Its great opening up thr nesting boxes and catching the smell and it's not all in your face and abrasive or harsh chemical smelling. Thanks for creating a safe & usable product!

Dustin P.

Our birds can’t get enough of GrubTerra mealworms. A quick, healthy, and high-protein treat that our flock looks forward to every day. 10/10!

Is the worst Customer Service I’ve been trying to return it before even I received it due to lost my Chicken and they want return whatsoever. I tried to cancel my order before even they shipped it because I tracked it when I sent the email and it says processing it’s been for two weeks dealing with them and I did not get my money back or the label to return the package

I absolutely love Grub Terra coop refresher! It leaves the hen house smelling fresh and helps repel flies and other bugs away. My hen house uses the deep litter method and once a month I apply first Saturday lime and in between that I add mint coop refresh. I also sprinkle a little under the nesting pads! I have to say that a little bit goes a long way! It has made such a difference. I have this product on auto ship. I don’t think I could go without it. Thank you Grub Terra for this amazing product!!

Dorothy B.

I was honestly surprised by how well this worked. Sprinkled Grubterra Chicken Coop Refresher in our coop with fresh bedding, and our entire flock immediately came in to investigate. No harsh smell, no fake perfume->just clean and MINTY!! Four weeks later and the coop still smells great. It’s natural, easy to use, and safe for the chickens, which is huge for US. We’ve used it on the coop floor. We use two packets for our coop but probably could of used just one. If you keep chickens and want odor control without chemicals, this is absolutely worth it.

Valerie H.

The water resistant property is impressive! My egg boxes get pelted with rain and leaks in but I’ve seen less rain after this stuff!

WOW! The mint coop refresher smells amazing. I used it in both my coops. I have a small coop on my front porch with two birds and I love the smell of mint from my window -- rather the smell of coop poop. My other coop has 13 ladies. I have two different coop set ups and they both smell fresh.

I love this Coop Freshener! To be honest when I first ordered I did not realize it came in individual packs but now I am so pleased with this new method.

Definitely recommend!

This coop refresher is a breath of fresh air in a package. 1 pack lasts for weeks and my girls love it as much as I do!

irene d.

I like this product and it does what I expected it to do. I feel like the pouches should be bigger though; my coop is pretty smelly. Maybe I should have cleaned it better first. It does make a difference.

I place my first order that was place on July 28 and it was delivered on September 18. I love the products, but kind of irritated that I didn't get to try it before my renew was coming up. It does cover the smell of my chicken coop.

Daniel B.

This stuff is AMAZING. In the large chick brooder I add one packet over the course of a week and it works SO WELL! One whole pack goes in my run and has lasted over 3 weeks in the HOT HUMID RAINY South Florida Summer
