Is DIY cockroach control best?

Cockroaches are unwelcome pests that can carry pathogens and pose health risks in your home. Because they often live in drains, sewers, and garbage areas, they can spread bacteria and contaminate surfaces.

With concerns like these, many homeowners look for quick solutions. Along with traditional methods, some turn to electronic roach repellents. But do electronic roach repellents actually work? Here’s what you need to know before relying on them for cockroach control.

How Do They Work?

Electronic cockroach repellent supposedly works by emitting ultrasonic, or very high frequency, sound waves. This noise is supposed to cause response which can confuse, and may even kill, certain pests like cockroaches.

These systems plug into wall outlets and can be purchased at any home hardware store. The sound is too high for humans to hear and should cause no disruption for members of the household. Some consumers may find electronic cockroach repellent preferable because of its ease of use. They may even perceive it as a more humane method of dealing with household pests. 

Are Electronic Cockroach Repellents Effective?

On paper, electronic cockroach repellent might seem like the perfect solution to a common problem. Unfortunately, these systems aren’t all they’re cracked up to be. In fact, many manufacturers of these products have come under fire from the Federal Trade Commission for making false advertising claims that were not backed up by actual research.

Additionally, a 2006 study from researchers at Kansas State University showed that these devices have little to no effect on cockroaches, specifically German cockroaches (which are commonly found in homes).

If the scientific evidence isn’t enough to convince you, there are other issues with these devices, as well. The first is that the sound waves are only transmitted for a very short distance and can easily be blocked or disturbed by common household items, like furniture or floor lamps. The sound waves may also cause problems for small household pets, like guinea pigs or hamsters, and interfere with alarm systems.

Is DIY Cockroach Control Best?

When it comes to pest control, it may be tempting to try do-it-yourself methods like electronic cockroach repellent. However, this often winds up being more trouble than it’s worth.

First, it’s important to consider effectiveness issues. Of course, electronic repellent probably won’t work. Other DIY options like bait stations may only partially eliminate cockroaches, and boric acid can be easily misapplied. With methods like these, following label instructions and professional training is very important.

In your search for the right treatment, you may also wind up spending more on control methods than you would if you contacted a professional in the first place. It’s also important to properly apply any pest control substances, and most homeowners do not have all the training that these require. This can present certain issues.

The bottom line is, when dealing with a cockroach or other pest problem, contacting the professionals is your best option for effective treatment. Our trained pest control professionals will conduct an initial inspection and then treatment, as well as follow-up treatments, to help you get your pest problem under control.
