6 Best Nesting Box Designs For Minimizing Mites Without Chemicals
Protect your flock from mites, no chemicals needed. Discover how nesting box design, materials, and ventilation create a naturally pest-resistant environment.
Dealing with poultry mites is one of the most frustrating battles a flock owner can face. Once they get a foothold, they are notoriously difficult to eliminate, hiding in every crack and crevice of a wooden coop. The single best way to fight them is to never let them get established, and that fight begins in the nesting box.

Why Nest Box Material Matters for Mite Control
Mites thrive in dark, tight spaces where they can hide from predators and treatments. A traditional wooden nesting box is a five-star resort for them. The porous nature of wood, combined with the inevitable cracks, seams, and joints, creates a perfect breeding ground that is nearly impossible to fully clean.
This is where material selection becomes your primary weapon. Non-porous materials like plastic and metal offer mites zero places to hide. There are no microscopic pores for them to burrow into. A smooth plastic or metal surface can be wiped, scrubbed, or hosed down, completely removing any mites and their eggs. While a well-built wooden box can work, you’re always fighting against the nature of the material itself. Choosing plastic or metal from the start eliminates the mites’ habitat by design.
The Nestery by Chick Cozy: Easy-Clean Plastic
The Nestery is a great example of a design that prioritizes hygiene. It’s a modular system made entirely of heavy-duty plastic, which means it’s completely non-porous. The surfaces are smooth, and the pieces snap together, leaving minimal seams for pests to exploit.
The real advantage is how easy it is to maintain. You can pull the whole unit out and hose it down, or even take it apart for a deep scrub with soap and water. This level of cleaning is simply not possible with a wooden box that has been nailed and glued together. While the upfront cost is higher than a DIY plywood box, the time saved and the peace of mind from avoiding a mite infestation are well worth the investment for many small flock keepers.
Duncan’s Poultry Rollout: Durable Metal Design
If you want something that will outlast your coop, a metal nesting box is the answer. Duncan’s Poultry makes a rollout box that is the definition of durable and mite-proof. The galvanized metal construction is completely impervious to mites, pecking, and rot. It’s a "buy it once, cry once" piece of equipment.
The rollout design is a secondary benefit for mite control. By gently rolling eggs away into a protected collection tray, it keeps the nesting material cleaner and drier, making it less attractive to all kinds of pests. The main tradeoff with metal is temperature regulation. You must place it out of direct sunlight in a well-ventilated coop to prevent it from getting too hot in the summer. But for sheer cleanability and mite resistance, nothing beats solid metal.
Best Nest Box: Roll-Away Mite Prevention
The "Best Nest Box" brand has become popular for good reason. It effectively combines the benefits of modern materials with a smart design. These boxes typically use a combination of plastic side panels and a sloped, coated wire or plastic floor. This system attacks the mite problem on two fronts.
First, the materials themselves are non-porous and easy to clean, just like other plastic and metal options. Second, the roll-away feature drastically reduces the amount of manure and broken egg residue in the nesting area. Mites are attracted to this organic matter, so a cleaner box is a less inviting box. It’s a complete system that not only prevents mites but also gives you cleaner eggs with less work.
UC Davis Plywood Plan: A DIY Mite-Free Box
For those who prefer to build their own equipment, not all wooden designs are created equal. The nesting box plan developed by UC Davis is a solid, practical design for a DIYer wanting to minimize mite habitat. Its brilliance lies in its simplicity and its focus on easy disassembly for cleaning.
However, just building it out of plywood isn’t enough. To make a wooden box truly mite-resistant, you must seal it. After assembly, caulk every single interior seam and joint. Then, apply several thick coats of a durable, glossy paint. This effectively encases the wood in a non-porous, plastic-like shell, filling the cracks and pores where mites would otherwise hide. This crucial step turns a potential mite haven into a defensible, cleanable space.
Miller Little Giant: Simple, Scrubbable Plastic
Sometimes the simplest solution is the most effective. The Little Giant nesting box, available at most farm supply stores, is a perfect example. It’s a single piece of molded plastic, which means there are absolutely no seams, joints, or cracks for mites to hide in. It is functionally a plastic bucket turned on its side.
This is the ultimate low-cost, low-maintenance option for mite prevention. You can pull it off the wall, dump the bedding into the compost, and scrub it clean in a tub of water in under five minutes. It doesn’t have a roll-out feature, but its incredible ease of cleaning makes it a top contender, especially for smaller flocks where you only have a few boxes to manage.
HenGear Community Box: Large-Scale Mite Defense
If you’re managing a larger flock of 20 or more hens, individual nesting boxes can become a major chore to keep clean. A community nesting box, where multiple hens lay in one large area, can be a mite nightmare if made from wood. This is where a system like the HenGear Community Box shines.
These units are built from the ground up with hygiene in mind, using the same principles of plastic and metal construction and a roll-away design. They accommodate a large number of birds in a single, easy-to-manage system. Instead of scraping out a dozen mite-prone wooden boxes, you maintain one highly mite-resistant unit. The investment is significant, but for a larger hobby farm, it streamlines chores and provides a powerful defense against pests.
Herbs and Dust Baths: Your Next Line of Defense
Your choice of nesting box is your foundation, but you can build on it with other natural deterrents. Sprinkling dried herbs like mint, lavender, wormwood, and oregano into your nesting material can help repel mites. They dislike the strong essential oils in these plants, making the nesting area less attractive. This isn’t a cure, but it’s an excellent preventative measure.
Even more important is providing your flock with a high-quality dust bath. A mix of dry soil, sand, and a bit of wood ash or food-grade diatomaceous earth (DE) is perfect. Chickens instinctively use dust baths to control external parasites, including mites. By providing them with the right tools, you empower them to handle their own pest control, reducing the chance they’ll bring mites into your clean nesting boxes in the first place.

Ultimately, winning the war against mites without chemicals comes down to one thing: eliminating their habitat. By choosing a nesting box made of non-porous materials and designed for easy, thorough cleaning, you remove their ability to hide and reproduce. It’s a simple, proactive strategy that will save you countless hours of work and keep your flock healthy and stress-free.
