Bell Howell Ultrasonic Pest Repeller Review- [Pros & Cons]

Some time ago roaches were creating a lot of terror in my kitchen.

And even after using some natural methods like vinegar, baking soda, etc, they were not giving up on me like a stubborn enemy.

Then I was advised by my neighbor to use an ultrasonic pest repeller.

I had heard about ultrasonic pest repellers but I didn’t believe in them at all.

But since my neighbor suggested it, I felt that there must be something special in it.

So I was curious to dig more into it.

Now a lot of questions started popping up in my mind do these pest repellents really work?

And if it works then how and what is the technical process behind it? And what all sort of insects, it can kill?

Will it cause any harm to me or to my children and pets?

I had to buy it to satisfy my curiosity and I did because if it solves my problem for $19 there is no need to break my bank to hire a professional.

And the biggest thing is you can judge something only after using it.

So I bought it and I am going to share each and every pros and con that I experienced about this product, in this Bell Howell Ultrasonic Pest Repeller Review“.

So if you are in hurry let me cut it into a short review with pros and cons.

But if you have enough time make sure you read it completely, after all, you will learn many things.

Short Review of Bell Howell Ultrasonic Pest Repeller:

Bell & Howell is a US-based brand that was established in 1907. It is a renowned brand in the consumer electronics segment.

Recently, the brand launched its ultrasonic pest repellers, which are still in the hype in the market.

I bought this product to get rid of roaches but I didn’t know that it would get rid of spiders, mice, rats, and ants too.

Although I didn’t see much of an impact on the Lizards.

The second good thing was that the rats were not dying in the house. They were going out of the house in an unconscious state.

The third thing that I liked was that as mentioned on the product, it was absolutely pet and children friendly as it does not contain any chemicals and also it is odor-free so no health issues were seen.

The fourth thing I would like to tell is that it is super easy to install, only you have to plug it in the power socket and it starts working as soon as you switch it on.

The one drawback that I will mention is for the first 7 days I did not see any effect on the roaches and I started thinking that it is useless.

But after 10-11 days it started showing a little effect and by the fourth week, I had gotten rid of half 75% of the roaches. It really felt like a big victory!

Let us now have a look at its pros and cons.

Pros & Cons of Bell Howell Ultrasonic Pest Repeller:

  • Super Effective On Roaches, Spiders, Rats and Ants
  • Very Affordable
  • Easy to Install
  • Children & Pet Friendly
  • No Chemicals and Odorless
  • Rats Die going out on their own
  • Takes almost two weeks to show effect
  • The plastic material is not enough strong
  • it doesn’t work on lizards
  • Red Power Light is too bright

Now we move on to an in-depth review in which we will try to take a closer look at the Bell Howell Ultrasonic Pest Repeller.

An In-Depth Review:

In this in-depth review, we will go through each and every detail of this product. We will talk about the product’s design, how it works, how effective it is, and how to use it. Along with this, we will also talk about its side effects.


This product is white in color and square in shape and has curved corners.

It is so small that you can carry it in your pocket while traveling. It is 4x4x4 inches in Length x Width x Height.

There is a Bell & Howell branding at the bottom of the front and a power light just right above it to indicate whether it is on or off.

They should have been given a green light also, which indicates whether ultrasonic waves are coming out of it or not.

There is a window-like space above the power indication light from which the ultrasonic waves are emitted.

Many electronic paste repellers have this window on the backside, which reduces their effectiveness. So this one is a plus point of Bell Howell’s product.

It weighs 0.55 pounds, which I found to be a bit more than other pest repellers. The machinery inside is heavy while its outer plastic body doesn’t seem that strong.

Its plastic body feels quite breakable, although I haven’t tried dropping it yet.

Overall, in terms of design, I would give it only 3.8 out of 5.

How Does Bell Howell’s Ultrasonic Pest Repeller Work?

Like other ultrasonic pest repellers, this one also emits ultrasonic electromagnetic waves.

In simple words, ultrasonic waves mean a sound that cannot be heard by humans but is intolerable to some insects such as spiders, mosquitoes, ants, roaches, etc.

Electromagnetic waves refer to the waves produced by the vibration of the magnetic field and electric field.

These ultrasonic electromagnetic waves disturb the nervous system of insects. And not only that but also completely destroy their senses of hearing and smell.

And that is why they start running away from your house.

To use it, you have to plug it into the power socket and it automatically turns on as soon as you plug it in.

As soon as you plug it in, its red flash light starts blinking which means ultrasonic waves are coming out of it.

Whenever you plug it in, keep in mind that it is in an open space and nothing is blocking its waves.

For example, installing it behind a sofa will not work effectively.

Does Bell & Howell Ultrasonic Pest Repeller Really Work?

When you see reviews of this product on online stores, you will get mix opinion of people.

For example 50% of the people are saying it works well and the remaining 50% are saying that it doesn’t work effectively.

So what is the real truth?

I bought a 4 unit combo of this product. Out of which 2 units did not work at all. But there were 2 units which worked effectively.

Now it may be that for whom this product did not work, all four of their units may be faulty.

The red light blinks in faulty units too but the units don’t actually emit ultrasonic waves or have a low frequency, so they don’t work effectively.

How Long Do Bell and Howell Ultrasonic Pest repellers Last?

Even here nothing is fixed. Many people say that their Bell and Howell units are working well for 3-4 years. And some say that they stopped working within a few weeks.

If I tell my experience, it supported me for 1 year.

But after a year its red power light got dim then I understood that its efficiency has reduced now.

If the faulty units are not delivered to you, they will work well for 1-2 years. But if units are faulty, they may stop working within a few weeks or a few days.

Does Bell & Howell Ultrasonic Pest Repeller Have Any Side Effects?

As it is mentioned in big letters on the product that no chemicals have been used in it.

When I used the Bell & Howell Ultrasonic Pest Repellent, I didn’t see anything that could really help me to know if it actually has a bad effect on humans or pets.

So all I will say is that it does not have any side effects on humans, children, and pets and the other good thing is that it is completely odorless.

But yes, its red power light is very bright and if you like darkness at night, then this light can bother your sleep.
