Learn 6 organic coop pest control methods passed down by farmers. Safeguard your poultry with natural, effective, and time-honored techniques.
Keeping pests out of the chicken coop is a battle that never truly ends. The moment you let your guard down, something will try to move in, whether it’s mites, lice, or rodents. The key isn’t finding a single magic bullet, but building a resilient system using simple, effective tools that have stood the test of time.

Identifying Common Coop Pests and Their Signs
Before you can treat a problem, you have to know what you’re looking for. The most common coop pests are external parasites like mites and lice, and rodents like mice and rats. Each leaves a distinct calling card.
Mites are tiny arachnids that feed on blood, often causing anemia, feather loss, and pale combs. You might notice your birds are listless or see scabby, crusty buildup on their legs and feet, a classic sign of scaly leg mites. Lice are larger, fast-moving insects you can see scurrying near the base of the feathers, especially around the vent, leaving behind clusters of white eggs. Rodents are easier to spot by their droppings, chewed feed bags, or tunnels burrowed under the coop walls. Regular inspection is non-negotiable.
Harris Food Grade Diatomaceous Earth for Mites
Get 4lbs of HARRIS Food Grade Diatomaceous Earth, a natural product with no additives, OMRI listed for organic use. Includes a powder duster for easy application.
Diatomaceous Earth, or DE, is the fossilized remains of tiny aquatic organisms. Its microscopic edges are razor-sharp to insects, working by physically piercing their exoskeletons and causing them to dehydrate. For mites and lice, it’s a death by a thousand cuts.
The best way to use it is as a preventative dust. Lightly sprinkle it in nesting boxes, the corners of the coop, and in your flock’s favorite dust bathing spots. Some folks dust their birds directly, but be careful—it’s a fine powder that can irritate respiratory systems, both yours and your chickens’. Always use food-grade DE, wear a mask when applying it, and use it as a tool, not a cure-all.
First Saturday Lime for Coop Sanitation
Don’t confuse this with the caustic hydrated lime used for construction or the ineffective barn lime (plain old crushed limestone). First Saturday Lime is a specific formula of hydrated lime that’s been treated to be safe for animals while remaining highly effective at sanitation. It works by dramatically raising the pH of the coop floor, creating an environment where bacteria, parasites, and insect larvae can’t survive.
Think of it as a hard reset for your coop’s bedding. After a deep clean, you apply a thin layer to the floor before adding fresh bedding. It absorbs moisture, neutralizes ammonia odors, and helps keep the pest life cycle broken. It’s a powerful preventative measure that contributes to overall flock health far beyond just pest control.
Scratch and Peck Feeds Nesting Box Herbs
Herbs in the nesting box are one of the oldest and most pleasant pest control methods. Strong-smelling herbs like lavender, mint, chamomile, and calendula have been used for centuries to repel insects. The idea is simple: pests find the aromatic oils overwhelming and are less likely to settle in.
Let’s be realistic, though. A few handfuls of herbs won’t solve a raging mite infestation. This is a subtle, preventative layer in your overall strategy. It makes the coop a less inviting place for pests to begin with, and it has the added benefit of making your coop smell fantastic. It’s an easy, low-cost way to make the environment healthier and more pleasant for both you and your hens.
The Old-Timer’s Trick: Using Hardwood Ash
If you heat with a wood stove, you have a free and effective pest control tool right at your fingertips. Cool hardwood ash serves a similar function to diatomaceous earth. The fine, powdery particles get into the joints of insects and clog the breathing spiracles of mites and lice, suffocating them.
The best application is in a dedicated dust bath. Chickens instinctively know how to use it, working the ash deep into their feathers to dislodge parasites. Just be sure the ash is completely cold and only from untreated hardwood—never use ash from charcoal briquettes, pressure-treated wood, or garbage. It’s a messy but time-honored method that turns a waste product into a valuable resource.
Arbico Organics Mite-R: Biological Control
Sometimes, you need to fight fire with fire. Biological control involves introducing a natural predator to manage a pest population, and for mites, this is a game-changer. Arbico Organics sells predatory mites (Hypoaspis miles) that actively hunt and consume harmful poultry mites, their eggs, and their larvae.
This is a targeted, set-and-forget solution. You release the predatory mites into the coop, and they go to work without harming your chickens in any way. The major tradeoff is that you can’t use it in conjunction with dusts like DE or wood ash, as those will kill your beneficial predators, too. It’s a brilliant organic option for a persistent problem, but it requires you to commit to a single, focused strategy.
Victor M156 Rat Traps for Rodent Control
Rodents are a serious threat, contaminating feed, spreading disease, and even preying on young chicks. While there are many options, nothing beats the simple, lethal effectiveness of a classic wooden snap trap. They provide a quick, humane kill without the risks associated with poisons.
Poisons can lead to secondary poisoning of predators like owls or your own barn cat, and a poisoned rodent can die inside a wall, creating a horrible stench. The key to successful trapping is placement. Set traps along walls and in corners where rodents travel, and place them inside a box or under a crate to prevent your chickens from accidentally setting them off. Bait with peanut butter or nesting material for the best results.
Creating Your Integrated Pest Management Plan
None of these methods work in a vacuum. The goal is to build an Integrated Pest Management (IPM) plan, where multiple strategies work together to create an environment that is inhospitable to pests. A good plan doesn’t wait for an infestation; it actively prevents one.
Your IPM should be a simple routine built on a few core pillars:
- Sanitation: Regular coop clean-outs and moisture control with products like First Saturday Lime.
- Exclusion: Sealing up holes in the coop to block rodent entry.
- Prevention: Using nesting herbs and providing dust baths with wood ash or DE.
- Monitoring: Performing weekly health checks on your birds to catch problems early.
- Action: Having traps or predatory mites on hand to deal with a problem the moment it appears.
Ultimately, a pest-free coop comes down to consistent management, not a single product. By layering these simple, proven methods, you create a defensive system that is far more effective than any one-off treatment. A healthy coop is a clean, dry, and observant one.
