The last thing anyone wants in their home is a cockroach infestation. While we all wish that cockroaches would just go instinct, that simply isn’t realistic. However, if you’re attempting to keep roaches out of your house or business, that’s what we’re here for. 

We combed the internet for information on which pesticides and traps to employ, as well as when to bring in the pros. Given the tenacity of your adversaries, the optimum remedy for your infestation will most likely be a mix of two or three of the solutions listed below.

The most efficient and specialist-approved cockroach repellents are listed below. A few of these roach killers and traps kill roaches on impact, while others allow roaches to carry poison back to their nest. This is your ultimate guide for getting rid of roaches, so let’s get started with the common mistakes people make! 

What are the Common Mistakes to Avoid When Repelling Roaches?

To ensure that you have the best chance possible to get rid of these nasty critters, we’re going to discuss a few things you should avoid. For starters, saying sayonara buckaroo to roaches comes with consistency and determination. 

Don’t expect to put some traps out and never have an issue again. Repellent does a great job at just that… repelling, not eradicating. Another thing you’ll want to do is try a combination of products. These bugs are sneaky and we have to use our wits against them when it comes to reclaiming our space! 

With that being said, don’t use both repelling methods at once. The layers we are talking about are concentric, one after the other. Never spray one over the other since they will typically cancel each other out. The result is that you have less or no insect control than previously.

Finally, clean and wipe everything before spraying anything, not after. It may appear to be plain sense, but we’ve seen far too many individuals sweep and mop after us in an attempt to keep their homes tidy. 

We commend their attempt, but the timing is terrible. They’re just doing one thing: cleaning up whatever we spray. Now that you know about common mistakes to avoid, let’s talk about some natural smells that you might enjoy that terrorize roaches!  

The Power of Flowers

Cockroaches and other insects are naturally disgusted by certain scents. The most effective are chrysanthemum flowers, commonly known as garden mums, which have a powerful repelling effect. 

As a defense against invasive insects, they release pyrethrum, a natural substance. Pyrethroids, a synthetic form of pyrethrum, are the active component in many pesticides. 

Cockroaches can be deterred by planting chrysanthemums throughout the home and putting potted chrysanthemums in the kitchen and around the exterior of your home. It will take a lot of them, spaced no more than a foot apart, to create a protective barrier.

#3 Best Natural: Peppermint Essential Oil

Peppermint oil is one of the essential oils that cockroaches and other pests strive to stay away from as much as possible. It is simple to use. Fill a half-empty spray container halfway with water. Then add 10-12 drops of peppermint oil and gently shake it. Put the lid back on and give it a good shake.

Spray this mixture sparingly about the areas you don’t want cockroaches to enter. Make a ribbon that is 6 to 12 inches wide. Don’t go overboard with the spray. 

Continue to apply once or twice a week, softly spraying each time. It won’t stain your furniture or carpets, so you can rest easy when using it. You can generate gallons of spray from just one bottle of concentrate because you only use a small amount at a time.

This is a great option for people looking for a safe and natural option. Many households have a bottle of peppermint oil laying around and can easily make a mixture to tell those cockroaches where they’re not allowed!

Choosing the Best: What to Look For

So, now that you know about all of the great options available, let’s take a look at some tips when it comes to repelling these creeper critters. 

Keep Your Home Clean

To get rid of roaches, there’s one guideline that takes precedence over all others: The first and most efficient line of protection is appropriate food storage and trash disposal. The easiest method to deal with a cockroach infestation is to prevent them from entering in the first place. 

That involves getting rid of everything that attracts insects, such as food, drink, and litter, which provides shelter and warmth. 

Roaches are some of the toughest pests on the planet, making it difficult for people to get rid of them on their own. People may, however, take efforts to reduce cockroach infestations by putting up barriers and keeping their homes clean.

Ease of Use 

Something to consider when looking at cockroach repellent is how easy it is to use. Is it something you can easily slip under the kitchen sink? Do you have to put on a mask and goggles and wave a wand all around your home? 

There are a variety of options listed above to allow everyone to find the type of product that meets their needs and lifestyle. 

Toxicity

Whether you live alone, with children, or furry friends, the ingredients that make up repellent matter. 

We looked into if the active components were harmful to people and animals. Fundamentally, all of it is slightly hazardous, however, some alternatives, like Raid’s Bait Stations, are much less dangerous for pets. 

Effectiveness

The most significant characteristic of a roach killer or trap is, without a question, its effectiveness. We took into account the active substances, professional advice, and user feedback.

The Different Types of Cockroach Repellent: Pros and Cons Compared

The type of repellent you use is very dependent on your environment and the goal you want to achieve. There are repellents for both large and minor infestations, so make sure you choose the proper one.

Spray Repellent

If you’re struggling with a roach outbreak and know precisely where it’s coming from, a spray repellent is ideal because it kills roaches on touch and works rapidly. 

It is very simple for other cockroaches to become contaminated just by being in close proximity to one that has been sprayed. Roaches consume the dead bodies of other roaches, thus this is a good approach to get rid of any roaches that are still around. 

The only problem is that in order for this to work, you need to know exactly where the colony is. You can’t expect the roaches to keep away by spraying all over the place.

Pouches/Stations

These are efficient techniques since they can be set and forgotten. Repellent pouches are a mixture of odors that roaches despise, causing insects to avoid them. If you have a basic notion of where the roaches are coming from, you may place the pouches there to stop them from spreading. You may use this to construct a great barrier around your house.

Ultrasonic Repellers

This is definitely the most efficient option. The wider the range, the better, and if you can locate one that can pierce through walls, you’re set. Only cockroaches can hear ultrasonic repellers, which emit waves of sound that only they can hear. This is fantastic since there is no need to spray, set traps, or do anything else. When you connect the repeller to the wall, it instantly starts operating.

Verified Review: User Experience

It’s important to buy a product you can trust. How do you know you can trust something you’ve never personally tried? Read the reviews! 

One user on Amazon has this to say about our overall favorite from Eco Defense: 

“I’m in central Texas and it works great! It has kept away our carpenter ants, silverfish, cock roaches, and spiders. We had a lot of bugs, and the day after I sprayed they were gone. I started noticing a few silverfish after about 4 months, then a few cock roaches started showing up as well. I’ll go ahead and spray again, and ordered a second bottle! I used almost an entire bottle the first time I sprayed around the outside & inside of our 2000 sq ft house.”

Another reviewer has high praises for Ortho Home Defense Insect Killer with this comment:

“I live in Florida. You have to have pest control in place or you will end up with roaches in this area of the country. And good luck getting rid of an infestation of those. I have a severe phobia of them. I’m not from here. They are everywhere and make the skin crawl. I’ve literally have had nightmares about them. So I was hesitant to try the product, even after the positive reviews and results of relatives and friends.

I have been using this for almost a year and have not seen one live roach to date. I’ve seen two in my house both dead. This is so much cheaper than $75-100 four times a year for professional pest control. And you’re paying all that for them to come in spray the same or a similar product. Why throw all the money away when you can do it yourself in about 30 minutes for $20?!”

They make a great point! Save money and try out one of the products above to kick roaches to the curb!

The Best Cockroach Repellent for 2022 FAQs (Frequently Asked Questions) 

What will scare a cockroach?

Cockroaches are known to be scared of people and other mammals or creatures that are larger than them. They perceive humans as predators, and their natural reaction is to flee. Citrus, peppermint, lavender, and vinegar, on the other hand, are strong and unique odors that they despise.

Will leaving the lights on deter roaches? 

Cockroaches are nocturnal creatures who like to stay out of the light. Yet, that’s not because light hurts them. Cockroaches recognize that they can’t escape or elude predators while they’re out in the open. Keeping lighting or a lamp on all night will not keep them away.

Is it true that killing a cockroach attracts other cockroaches? 

Although it is not true that killing a cockroach would spread its eggs, killing a cockroach with violence might attract more. However, this might work in your favor if it pulls bugs out of hibernation so they can be removed.

Why am I suddenly seeing roaches? 

When somebody “suddenly” encounters a cockroach, it’s usually not as unexpected as it appears. In other terms, they’ve most likely been in the house for some time, and you’re noticing them is more of a fluke than anything else. Perhaps you shifted something they’ve been lurking behind for the past few weeks.

What scents deter roaches? 

Cockroaches have a keen sense of smell, which they employ to locate food. You may reap the benefits of this by repelling them from your house with odors they despise, such as thyme, citrus, basil, mint, and citronella.
