What Is A Roach Repellent?

Cockroaches can be super challenging to eliminate out of your home. Of course, you can resort to killing them, but those stubborn invaders have developed their immune systems, along with their strong shells, to withstand many of the insecticides and extermination techniques available today.

A roach repellent allows you to avoid confrontation all together. We’re not talking about repellent-labeled products only, but rather the whole array of methods used to drive cockroaches away.

Basically, a roaches repeller is a substance that puts off the cockroaches from getting close to a certain area or a surface that has been treated with this material. Thus, keeping your place free from the nasty pests.

Roach repellents may be made of all-natural ingredients, chemically altered compounds, or some kind of ray-emitting device.

How Well Do Roach Repellents Work?

When you think about how well a roach repellent would work for you, it’s important that you get your facts straight first.

Tons of people are under the misconception of roach repellent being deadly to the intrusive insect, however, you should know that by no means do repellents kill the cockroaches.

Whether or not roach repellents will work is out of the question. They will work, it’s just a matter of how effective their results will be. This depends on how big your problem is.

If you’re hoping to resolve a full-blown infestation issue, then you’re going to be disappointed as applying repellents may actually cause the cockroaches to hide deeper inside the cracks and grooves, or just chase them away into the next room.

A roach repellent is more of a prevention method, and in that aspect, it brings the heat. Alicia Phillips from Auburn University discussed the topic in her thesis where she highlights the significant efficacy of cockroach repellents in prevention, especially in scenarios involving food and other items that shouldn’t be treated with chemicals.

How To Properly Use Roach Repellent?

If we take a look at the best cockroach repellents, we’ll see the majority of products falling under one of three categories: pure essential oils, a mixture of essential oils and organic materials, and Ultrasonic producing devices.

More often than not, when people have disappointing results after applying a roach repellent, it’s because they didn’t really use it properly. This is why you should know how to work with your cockroach repellent; it can be the difference between never seeing those pests again and continuing having roommates you didn’t sign up for.

Pure essential oils typically come in small containers filled with highly concentrated oils, some are even 100% pure. To get the maximum effect, you’ll need to soak multiple cotton balls in the liquid then place them evenly in areas where cockroaches were detected. Make this a semi-daily routine, and you should be enjoying the natural scents while keeping roaches out for as long as you wish.

Mixtures of organic materials, such as vinegar, and essential oils are mostly available as natural sprays. Before applying such sprays, you should always remember to shake the bottle well in order to thoroughly re-mix all the ingredients. Spray the solution in cracks, nooks, and corners which are usually favorite hiding spots for the cockroaches.

You can also spray surfaces like tables and cabinets without having to worry about the sprayed material being toxic to you or your family as these mixtures are almost always chemicals-free.

As for Ultrasonic devices, all you need to do is plug it in. However, you may have to try out different placements to determine which location seems to work best as certain items can interfere with the ultrasonic sound waves in a negative way, such as furniture and large appliances which absorb sound.

Which Repellents Work Best For Roaches?

I just mentioned two of the best ways used to get rid of cockroaches; essential oils and Ultrasonic waves. So let’s break them down to understand what makes them actually work.

First up, we have essential oils. You can consider essential oils as a natural roach repellent. They have the advantage of being non-toxic to humans, which means they’re safe to use even in tricky settings like a baby’s room or a kitchen.

Essential oils, such as peppermint oil and catnip oil, are characterized by very strong odors. These odors can smell refreshing or be relaxing to humans, but on a tiny scale of a roach, they are too overwhelming that cockroaches will flee away from the scene.

Particularly in high concentrations, essential oils are the most effective with the widest range of coverage. In such a case, you can use them if you have a relatively large area to protect. These oils, however, will evaporate within a short period of time, so you’ll need to regularly reapply the stuff.

Now it’s time we talk about Ultrasonic devices. They generally produce waves at frequencies from 20 to 65 kHz. These sounds are too high pitched for us to detect, they’re also safe for pets.

However, insects and pests can easily hear these sounds and they are extremely annoying to them, so they try to avoid being exposed to those sounds.

The thing is, for the first couple of days, the pest activity will actually increase. This happens because the Ultrasonic waves irritate the roaches causing a stir up where the pests are driven out of their hiding spots. After that, you should notice a sharp drop in roach activity, disappearing completely in a matter of weeks.

What Are The Common Mistakes When Using Roach Repellents?

As I said before, how well roach repellents work, or even if they work at all, usually boils down to whether or not you’re using them correctly. For this reason, here are some common mistakes for you to avoid.

Using many kinds at the same time

If you’re using repellent sprays, don’t spray many different kinds on top of each other.

Applying one spray layer over another, in most cases, will lead them to cancel each other out, so you end up with less effective pest control or even none at all.

Instead, apply your sprays in a concentric pattern, one layer besides the other.

Spraying too little or too much

Many people struggle to find the right balance of their spray application. If applied too lightly, natural repellents will lose their effect as fast as they appear.

If you go too heavy on the product, you may end up irritating yourself with the smell. Even if the spray is odorless, it can leave a scent if you build enough concentration.

Don’t clean up right after you apply the spray or liquid

Sweeping or mopping your house to keep it clean is great and all, but wouldn’t serve you any good if you do it just following the use of a repellent. It may seem logical to you, but you’d be surprised at how many people think they’re helping by “spreading” the product everywhere.

Unfortunately, that’s not the case as they’re only wiping away the repellent, de-applying if you may. Instead, try as best as you can to clean and mop before you do any spraying.

Rushing the results

Pest problems aren’t solved overnight. It takes time to achieve a cockroach-free environment and it’s common for people to give up just as they’re about to get the situation under control.

It’s so easy to be impatient, especially if you’re living with the gross insects, but you should do your best not to give up too soon. You might be just one roach away from total elimination.

How To Pick The Best Roach Repellent?

For the sake of saving your time, effort, and most importantly, your money, we’ll be guiding you through the process of choosing the best roach repellent that’ll suit your specific needs. Here are some of the most important things to consider.

How big is the problem?

The first step to a correct pick is sizing up your mess. If you have a slight issue with roaches, natural repellents are a great way to deal with limited spread cockroaches. For example, if your neighbor is actually the source of your troubles, a smart way to go about it is to drive the invaders away from your home. You can do that by strategically applying repellents at possible entry points.

Cockroach repellents are also useful if you’ve already eliminated an infestation and you really don’t want to go through that pain all over again. They are an excellent prevention tool to stop occasional roach pop-ups.

However, if you’re faced with a full-blown serious existing infestation, repellents are very unlikely to offer help. Even they rid you of some roaches, chances are they’ve already laid eggs, in which case, you’ll need to find a roach killer.

Do you know where your problem is located?

If you can pinpoint the exact places where the roaches reside, then using a spray repellent would be ideal for you as it can be directed to those certain spots. However, if you don’t know where is your problem coming from, spraying roach repellent all over your home isn’t a viable option.

Ultrasonic devices, on the other hand, are perfect if you can’t determine where the problem is. You can set up one device in multiple locations, thus protecting a wide area.

Outdoors or Indoors?

If you’re planning on using roach repellents outdoors, say on a camping trip, then you want something with an extended effect to withstand exposure to the elements.

But if you’re only applying the cockroach repellent indoors, it shouldn’t disrupt the daily flow of your life.

Do you have kids or pets?

Unlike insecticides, natural repellents aren’t roach poison. That being said, as safe as they are, they’re still not quite suitable for environments with kids or pets. So, if you have any, you shouldn’t use sprays, powders, gels or liquids because let’s face it, they’re trouble makers. Children and pets may scatter powder, eat gels, or accidentally inhale too much spray.

Moreover, in high concentrations, essential oils may cause irritation to the eyes and skin for humans, especially those suffering from allergies. So always make sure your kids, as well as yourself, don’t inhale or taste the substance.

As for pets, they may be sensitive to natural cockroach repellents. Cats, for example, may suffer notable allergic reactions as their bodies don’t easily metabolize essential oils.

What about Ultrasonic repellents? Well, for kids and adults, they are safe. Humans aren’t capable of hearing ultrasonic waves above 20 kHz, so you have nothing to worry about.

For pets, it more or less the same story. Dogs, for instance, can hear ultrasound but their sensitivity depends on the breed.

Final Words

No matter the method, we can all agree that cockroaches need to go. In fact, it’s even better if we don’t have to face them altogether. For this reason, roach repellents are becoming popular day by day.

For me, the PestReject Ultrasonic Pest Repeller takes this one home. It depends on sound waves, so it’s super safe to use around my kids. Also. I don’t really know where those roaches may enter, so I like the wide coverage the Ultrasonic device provides as I don’t have the time (or energy) to go around spraying every inch of my home.
