We all know how important it is to keep rodents like rats and mice out of your barn. The leave trails of feces and urine and can even contribute to the spread of disease in humans and pets. They get into grain, chew through everything that isn’t metal, and can squeeze into the tiniest of holes.

So how do you keep rats out of your barn?

There are several different ways to keep rats and mice out of your barn. We think these four steps will get you started on the right path towards a rodent free barn.

1. Keep Grain in Rodent Proof Bins

Rodent proof bins limit the access of rats and mice to the really yummy stuff, your grains and supplements. My favorite answer to this are the simple metal trash cans you can find at your local home improvement store. These cans are a great investment and literally last for years. In my opinion, they are the best way to store grain outside of custom grain bins.

While 30 gallon trash bins like the one above are great for those large 50 – 75 lb sacks of grain, Amazon even has these super cute 10 gallon cans for smaller bags of supplements. These are great for those smaller 5 – 10 pound items or to store multiple smaller jars.

  • 【Beautiful and Functional】 Besides decorative purposes, this garbage can is also an effective way to store pet food, birdseed, toys, garden tools, and is recyclable. Also can be used to store painting brushes, etc. It can make a perfect addition to your indoor and outdoor space.

Once we have grain bins, we have a great starting point. We’ve eliminated one food source for the rats and mice. Next, let’s talk about how to get rid of the ones we already have.

2. Utilize Rat & Mice Traps Where Feasible

There are many kinds of mouse and rat traps on the market for sure. Some are more effective than others. What you don’t want to do is use poison. Rats that eat poison don’t typically die at the location. That means the poisoned rat or mouse will wander off somewhere and die. This could be in your hay, near a water source, in an open bag of grain, or somewhere where the barn dog could get a hold of it. In any case, this is absolutely something you DO NOT want to do in a barn.

Glue traps don’t really work for a barn either. Aside from not being very humane, the dusty environment in a barn can quickly render them ineffective.

So what is a good solution for trapping rats and mice in a barn?

Indoor Rat Traps

Electronic traps are hands down my favorite for indoor spaces like barn offices, grain rooms and tack rooms. They are more expensive to start but are humane AND reusable. The only downside is they are not supposed to get wet and, because they are electric, I wouldn’t use them in a hay room or any other room that has flammable material around.

Rat Zapper – Indoor Electric Trap Killer for Rats
  • ELECTRONIC RODENT ZAPPER – The Rat Zapper features cutting-edge technology with an intelligent wireless circuit sensor that quickly detects when a rodent has entered and immediately kills it.
  • HUMANE and SAFE – Only once the rodent steps on both metal plates simultaneously, will the device emit a shock that kills rodents humanely and instantly, without any pain or suffering.

Outdoor Rat Traps

Snap type traps are better suited for outdoor areas like hay rooms. In these areas, you will want to be very careful when choosing a trap. Safety is a big concern. You don’t want a child, dog, cat or any of the farm animals (chickens, goats, horses, etc) getting caught in the trap. You also don’t want any of them getting a hold of the body once a rat or mouse is caught.

The best types of outdoor rat traps for barns are the covered type similar to these:

  • PEACE OF MIND – Keep all of your loved ones and pets safe from dangerous rodents with UCatch Rat Traps Indoor and Outdoor! We use a dual entry design that maximizes the trap and kill rate of the rodent trespassers to 99.9%!
  • HANDS-FREE TRAPPING – These rat traps indoor for home can be operated completely hands-free to keep you away from the filthy rodents that keep you up at night! Both set and dispose easily and safely.

Live Traps

If you know you need to eliminate rodents but are not a fan of traps that kill the rats / mice, there are several live trap models available as well. With this method you would have to find a way to transport and then release the animals that are caught. This company provides a variety of different live traps for mice:

Multi-Catch Mouse Trap by Catchmaster
  • READY TO USE: The Multi-Catch Mouse Trap effectively eliminates mice from your home. The ready-to-use mouse and rat traps are designed for maximum reliability and trap up to 12 mice per setting. There is no setup or assembly required with this reusable mouse glue trap.
  • YEAR-ROUND PROTECTION: The live trap is an effective alternative to standalone traps and glue boards that may not hold up as well in damp or humid areas like basements or bathrooms. When deployed under normal conditions our long-lasting mouse cage traps are effective for up to one full year. Our adhesive formula has been specially designed to prevent hardening that can limit the effectiveness of mouse glue traps indoor for home.

Trapping rodents is an ongoing process in any barn. In fact, with reusable traps, it just makes sense to leave them up year around. You will want to be sure to check them frequently though! But what else can you do? Adopt a barn cat…

3. The Barn Cat

got rats? hire a barn cat.

No rodent control article would be complete without referencing the ultimate hunter, the barn cat. With animal shelters at maximum capacity, many organizations throughout the United States are realizing that farms and ranches may just be the perfect placement for their feral cats.

Wild cats that are caught and brought into the shelter are often euthanized because they are un-adoptable. Their lack of human socialization makes them unwanted and sometimes even dangerous to handle. These cats are typically really good at three things:

  1. Finding their own food.
  2. Living Outside
  3. Staying away from humans.

They will still need to be fed of course. You’ll need to provide them with water and a warm place to sleep (most cats find the hay room super cozy). If you wind up with a feral cat, he or she will most likely stay out of your way. Sure, you may have to trap him once a year for vaccines but otherwise, they pretty much do their job and I think we can all feel better when we’ve saved a life.

Here is information on the Ventura County, California barn cat program for reference but look in your area too!

Now we’ve covered putting grain in bins, trapping existing rodents and hiring ourselves a rat killer…there is still one more thing we need to cover; overall cleanliness.

4. Keep the Barn Clean

Keeping the barn clean can go a long way towards helping minimize rodent populations. Here are a few things you can check around your barn:

  • Trash is disposed of properly, preferably in lidded containers.
  • Grain room is kept swept and free of any spilled grain.
  • Lids are kept on all trash bins at all times.
  • Loose hay is regularly swept off the floor.
  • Stall corners are cleaned in box stalls (rats love to burrow in a stall).
  • Horse grain buckets are kept clean and washed after feedings.
  • Human food is stored in rodent-proof containers.

What to do if you still have rats?

This list should really help you get started with eliminating rodents at your barn but it isn’t a fix-all. Ongoing cleanliness, routine trapping and proper grain storage are the best ways to encourage rodents to find a home where food is more easily accessible. If rats continue to be an issue, reach out to your local agriculture extension or university for additional recommendations. Let them know what you have tried and what the issue is and, typically, they are very happy to help you with suggestions!
