Have you ever considered chickens or ducks for pest control in the garden? It’s one of my favorite things about raising them!
They actually come with a lot of benefits (learn more about the benefits of chickens and ducks on the homestead here), but pest control is one of the biggest.
Between the three duck breeds and even more chicken breeds I’ve kept over the years, one thing has become clear: they’re truly the best pest control I’ve ever had for my garden and yard.
A few years ago, when I’d gotten chickens again after a break of a few years, I remember talking with a group of friends about ticks. It had been a brutal tick year, and everyone was complaining about it…
But I hadn’t noticed many at all.
It didn’t click until we were out on a hike, surrounded by ticks the whole time, that the difference was probably my flock. They’d been free-ranging a lot that season, and it turned out that was doing more work than I realized.

Summary
I’ve kept three duck breeds and even more chicken breeds over the years, and pest control has consistently been one of the biggest reasons I keep both. In this post, I’m breaking down exactly what each one actually eats, which breeds have been the best foragers in my experience, and how to figure out whether chickens, ducks, or both make the most sense for whatever pest problem you’re dealing with.
Ducks for Slug and Pest Control
There are a lot of reasons to get ducks (including how cute they are!), but pest control is one of my top reasons, and one of the most practical.
Chickens can be great for pest control too, and plenty of people use them that way. But ducks bring their own unique benefits to the job.
Overall, I’ve found ducks are better at pest control than chickens in one specific way: they eat a wider variety of pests, and they do far less damage to the garden while doing it.
Ducks eat:
- Mollusks like slugs and snails — these are truly hard to control any other way. I’ve tried.
- Pests found in wet conditions, like mosquito larvae
- Beetle and grub larvae
- A variety of small water creatures, including small fish
Because ducks don’t scratch the way chickens do, they’re ideal for going after slugs, snails, aquatic pests, and mosquito or beetle larvae without tearing up whatever they’re standing on.
That also makes them the better choice for damp, wet environments — the kind of spots chickens tend to avoid altogether (they’re princesses when it comes to wet feet!)
Duck Breeds for Pest Control
Of the three breeds we’ve kept:
- Cayuga
- Welsh Harlequin
- Brown Indian Runner
…the Brown Runners have been our best foragers by far.
My girls have always joked that the Runners are the leaders and everyone else just follows. I think it’s because they’re such good foragers.
They find the best spots where bugs are hiding or a tasty plant is growing, and they announce it to the rest of the flock (loudly!) so everyone comes running.
Runner ducks in general tend to be bred with a strong foraging instinct.
I’ve been told they were originally bred to do pest control in rice paddies, and honestly, you can tell — their upright stance makes them fast, quick enough to catch flying insects, and they’re just a more active breed overall compared to the others.
The Welsh Harlequins have been great foragers too, if not quite on the Runners’ level. Cayugas, similarly, aren’t as driven to forage as the Runners — of the three, I’d say they’re the least motivated forager, though they still do a fine job on pests.
I haven’t personally kept Khaki Campbells, but they’re generally considered one of the best foraging breeds alongside Indian Runners, so that’s another one worth looking into if foraging is your priority.
Why We Keep a Mixed Flock
In my experience, if you keep a mixed flock, the better foragers actually help teach the others. As I mentioned, the Runners are usually the leaders, finding great forage and calling the rest of the flock over to enjoy it.
That’s a big part of why I generally keep a mixed flock rather than sticking to one breed — you get the benefit of your strongest foragers pulling the whole group’s behavior up.
Chickens for Pest Control
Chickens love a lot of bugs. They won’t touch snails or slugs, but they’ll go after pretty much everything else… well, except squash bugs. My chickens have always turned their noses up at those, and I haven’t seen a duck particularly interested either.
They’re great at getting rid of ticks, flying insects, worms, and grubs. I’ve watched my chickens grab black flies right out of the air. And this spring, we had a bad tick season — until I started letting them free-range for a few hours a day for a couple of weeks, and the ticks were just gone.
I’ve noticed this pattern for years now, actually. In seasons when we free-range more, neighbors will be complaining about ticks everywhere, and we haven’t seen any at all.
Chickens do especially well in dry pasture and wooded areas.
Chicken Breeds for Pest Control
A lot of people will tell you Rhode Island Reds, or another high-energy breed, are the best foragers. That may be true for some setups, but honestly, I haven’t noticed much difference in foraging ability across any of the breeds I’ve kept:
- Australorp
- Ameraucana
- Rhode Island Red
- Barred Plymouth Rock
- Buff Orpington
- Black Copper Marans
- Welsummer
My guess is that comes down to choosing heritage breeds (which all of the above are).
Heritage breeds are birds bred to retain their foraging instinct, rather than breeds selected primarily for egg production or size, where foraging drive often gets bred out along the way.
So instead of picking a chicken breed based on which one is supposedly the “best forager,” I’d say pick based on the other traits like temperament, cold-hardiness, egg color, etc., and trust that a heritage breed will hold up its end on pest control regardless.
And as I mentioned earlier, I’ve found the better foragers in a flock to teach the others their skills, so the gap between the best forager and worst quickly closes.
That all being said, Ameracaunas are my favorite of all the breeds I’ve had. They seem to be the smartest and best at avoiding predators.
They also lay blue eggs (and lots of them) and, despite being just one breed, come in a huge variety of beautiful colors. And of course, they’re great foragers as well.
Chickens vs. Ducks for Pest Control: A Quick Comparison
| Pest/Conditon | Chickens | Ducks |
| Slugs and snails | Won’t touch them | Excellent |
| Ticks | Excellent | Not a primary target |
| Flying insects | Excellent (will catch in midair) | Not a primary target |
| Beetles and grubs | Excellent | Excellent |
| Mosquito larvae | No | Excellent |
| Small aquatic pests | Not likely (sometimes eat fish from a dry shore) | Excellent |
| Squash bugs | Won’t touch them | Won’t touch them |
| Garden bed impact | More disruptive — scratches and digs | Gentler — minimal scratching |
| Best envrinoment | Dry pasture, wooded areas | Damp, wet, or aquatic-adjacent areas |
Which One Is Best for Pest Control: Chickens or Ducks?
Here’s my perspective:
They’re both great for pest control in general. But if you have a specific need for mollusk control (think snails and slugs) ducks are the better way to go.
Chickens simply won’t touch the slimy things.
Ducks also don’t destroy a garden quite the way chickens can (though with the right setup, you can absolutely have chickens working a garden without wrecking it — that’s a whole other post).
If you’re looking for pest control with the least amount of garden disruption, ducks are a great, straightforward choice. That said, chickens and ducks each bring plenty of other benefits to a homestead beyond pest control.
If you already know what kind of pest problem you’re dealing with, that’ll put you in a much better position to decide whether chickens, ducks, or both make the most sense. But really, I think keeping both is a truly great option too.
You get the benefits of each, covering a much wider range of pests than either bird could handle alone.
Keeping Ducks (and Chickens) in a Small Garden Without Damage
My preference is to keep both chickens and ducks, since together they cover a much wider range of pests than either bird alone. Right now, mine live together and work through the garden as one flock.
If you want the full breakdown of exactly how I rotate them through the season, I get into that in detail in How I Use Chickens and Ducks as Part of My Permaculture Design.
But if your garden is small, you might worry that ducks — or chickens — could still cause damage, even with how much gentler ducks are by comparison. That’s a fair thing to think through.
Chickens are the bigger concern here. In a small garden, I’d only let chickens in to prep beds in spring or clean up in fall, unless you’re willing to get creative with the design — chicken tunnels, dedicated fencing, that kind of thing — to keep them out of anything you don’t want disturbed.
Ducks tend to do fine, even in tighter spaces. As long as they have enough total space without needing to stand directly in your beds to get it, you should be okay.
Each duck needs roughly 10 square feet of run space — so make sure that’s achievable in the paths alone, or include a bit more of the surrounding yard in your fencing.
That gives them plenty of room to hang out when they’re not actively on pest patrol, and they’re less likely to feel like they need to nest in your beds.
Though I’ll admit, even with my ducks having free access to the whole yard, they still chose to build a nest right in my yarrow. Go figure.
Where to Go From Here
At the end of the day, chickens and ducks aren’t in competition. They’re just built for different jobs.
Ducks handle the slimy, wet-loving pests chickens won’t touch; chickens clean up everything else, ticks included. Together, they cover more ground than either one could on its own.
If you’re still deciding whether chickens, ducks, or both make sense for you, pest control is really just one piece of the picture.
