Ammonia as a Pest Control Agent

For better understanding, it will be necessary to explain what ammonia is. Ammonia comes in liquid or gaseous form.

For this article, we will recommend the use of liquid ammonia. Ammonia has the consistency of water. It is also a clear liquid that has several uses.

Apart from pest control, it is also used for lots of other things. These include its use as a cleaning agent, used to repel moths as well as for eliminating odors.

But enough of that already! Can it be used to rid your home of bed bugs, fleas, ants, and other insect pests? Let’s find out.

Using Ammonia For Rodent Control

Using ammonia for rodent control is a practice that has been widely accepted due to its perceived benefits.

Mice and rodents cause all sorts of damage ranging from chewing on insulation, gnawing and burrowing upholstered furniture as well as building nests in electrical appliances.

These rodents also target food sources that are in abundance in homes. Access to such food sources is likely to result in the spread of diseases from rodents to humans.

In a bid to fight back, you’ll need to apply ammonia in a certain way.

  • How it Works

Ammonia has a characteristic smell similar to that of urine.

Now, both mice and rats are known to have an excellent sense of smell. Due to the similarity in smell to urine, ammonia is considered a sign of danger as rodents assume a predator is close by.

Due to natural survival instincts, rats will mostly keep away from areas with ammonia smell.

Applying ammonia won’t only give an illusion of predator presence. It causes damage to the respiratory system of rats and other rodents. These properties of ammonia make it a viable option for rodent control.

  • How to Apply Ammonia for Rodent Control

Whether faced with mice or rat problems, the approach to ammonia application is pretty much the same. First off, you’ll need to find or identify areas used by mice or rats to enter your home. These entry points are targeted for the application of ammonia.

Next, you’ll need to dilute some amount of ammonia with water. Equal amounts of ammonia and water should be mixed and emptied into cups. These are placed along identified entryways as well as possible pathways.

Ammonia can also be applied by having rags soaked in it. Such rags are placed around entry points used by these rodents. While applying ammonia indoors, it’s important not to ignore the outdoors.

Rodents come from outside and it’s important to treat your home’s perimeter.

Get some ammonia and have it sprinkled or poured in a line around the perimeter of your home. This acts as a barrier that rodents find difficult to breach. Has ammonia reapplied along with target points every few weeks?

However, it’s important to note that applying ammonia alone isn’t a very reliable way of tackling the problem.

While ammonia will repel rats and mice, it’s best to have such entryways or holes sealed up.

Using Ammonia For Snake Control

Most people will cringe at the thought of having snakes lurking within their surroundings.

The natural response will be to have them removed or expelled as fast as possible.

Now, some people might be unaware of the fact that snakes prey on rodents.

Having these rodent predators (snakes) removed only leads to a situation where there’s an increase in mice and rat populations.

For a lot of homeowners, both snakes and rodents including other pests aren’t welcome.

  • How it Works

The strong scent from ammonia affects most pests including snakes. Snakes will keep as much distance as possible from areas where ammonia is applied.

  • Applying Ammonia For Snake Control

Whenever faced with a snake problem, ammonia serves as a handy and ready solution.

Application is also easy! You’ll need to get some rags and have them soaked in ammonia solution. Place such rags around areas where snakes have been seen.

Common areas to find snakes include places near woodpiles as well as brushes among others. If you’ve done this but still see snakes around, you might want to call the pros for more comprehensive treatment.

Using Ammonia For Raccoon Control

Raccoons are also considered pests as they come around to cause all sorts of problems.

These pests are potential carriers of rabies. Plus, they create a wide range of problems such as digging up your yard and tipping over your trash can among others.

  • How Ammonia Works

The strong smell from ammonia is one of the key repellent factors that make it effective.

When a raccoon picks up the smell of ammonia, it assumes its food source has been compromised. Plus, the area is considered the territory of a male raccoon or predator.

  • Applying Ammonia for Raccoon Control

Ammonia application for raccoon control isn’t difficult at all. All you have to do is get some rags and have them soaked in ammonia. These should be dropped around areas most frequented by raccoons.

Sometimes, the repellent effect on raccoons is short-lived.

Raccoons are likely to return to their surroundings when they become accustomed to the ammonia smell. It’s best to have a wildlife removal service come around to handle your raccoon problems in the most comprehensive way possible.

Safety Considerations When Using Ammonia to Exterminate Pest

You must be wary of mixing ammonia with other substances. Ammonia in itself, when used according to instructions won’t do much harm.

However, mixing it with things like bleach will produce a harmful chemical mono-chloramine, di-chloramine, and tri-chloramine. These are in the form of fumes that are toxic to the respiratory system when inhaled.

If you must use ammonia for pest removal, you must carefully follow all instructions given by the manufacturer. Otherwise, you should seek alternative and safer ways of dealing with your pest problems.


Using ammonia for pest control is a common practice. However, it’s only one of several options available. We recommend seeking expert opinion on this pest control method.
