Will Ammonia Kill Rats? Here’s What to Know

Discovering rats in your home can be frustrating. Whether you spot rat droppings near pet food or hear scratching sounds at night, it’s natural to look for quick ways to get rid of rats. Many homeowners wonder if they can use ammonia as a DIY rodent repellent.

But can ammonia actually kill rats?

Let’s break down the facts.

Key Takeaways

• Ammonia does not kill rats and only repels them temporarily due to its strong smell.
• Its fumes can irritate a rat’s respiratory system but are not strong enough to cause death.
• Rats often adapt to ammonia, essential oils, and mothballs, reducing their effectiveness over time.
• Long-term rat control requires sealing entry points, removing food sources, using snap traps, or calling pest control professionals.

Does Ammonia Work to Kill Rats?

No, ammonia does not effectively kill rats. While its strong smell may repel rats temporarily, it’s not a reliable method for eliminating a rat infestation.

Here’s why:

1. Rats Avoid Ammonia’s Strong Scent

Rats have an acute sense of smell, which helps them avoid danger.

The smell of ammonia can irritate their respiratory systems, causing them to avoid areas where it’s placed. Some homeowners soak cotton balls in ammonia and leave them near entry points.

However, this effect is temporary.

They may leave at first, but once the strong scent fades, they often return. Using ammonia this way might help keep them away from certain areas, but it won’t kill them.

2. Ammonia Won’t Cause Fatal Respiratory Damage

Some people think ammonia can suffocate rats, but that’s a myth.

While its fumes can irritate a rat’s respiratory system, it takes extremely high concentrations to be lethal. In one study, rats had to be exposed to ammonia levels thousands of times higher than what you’d get from household use for it to be deadly.

Simply placing ammonia in spray bottles or open containers around your home might bother rats, but it won’t get rid of them.

3. Rats Quickly Adapt to Smells

Rats are intelligent wild animals that can adapt to unpleasant smells.

While ammonia might repel them initially, they often become used to the smell and return. This is similar to how they can learn to avoid rat poison or baited snap traps if not used correctly.

Essential oils like eucalyptus and peppermint oil, and mothballs are other common DIY repellents, but their effectiveness is also limited.

Over time, rats may ignore these scents and continue their search for food sources.

4. Ammonia Doesn’t Address the Root Cause of a Rat Infestation

While ammonia might repel rats, it won’t solve the underlying problem. Rats enter homes searching for food and shelter, often through small cracks and holes.

To get rid of rats, homeowners need to seal entry points using steel wool or other durable materials. It’s also important to remove food attractants like uncovered trash cans, spilled pet food, and accessible pantry items.

Cleaning areas where you’ve seen signs of infestations, like rat droppings with bleach or other cleaning products can help deter these pests.

How to Get Rid of Rat Problems Without Ammonia

Instead of relying on ammonia, it’s better to use more effective methods to keep rats at bay.

Snap traps are a solid option since they kill rats quickly and work best when placed where you’ve noticed rat activity. Sealing up holes and cracks with steel wool is another effective way to keep them from getting inside.

Rats can’t chew through steel wool, so it’s a reliable fix that helps stop critters from sneaking into your home.
