The Harris Bed Bug killer spray is regarded as one of the most effective bed bug sprays on the market.

But just how true are these sentiments? Does it really have the power to decimate bed bugs, bugs that have proven to be inherently the most difficult kinds of bugs to get rid of? In other words, what makes the Harris bed bug spray superior to many other products on the market?

We’ve researched comprehensively and have come up with this review. In it, we look at everything you need to know about this Harris Bed Bug spray and what makes it an outstanding product if it really is as good as the manufacturer claims it to be.

Harris Bed Bug Spray – Overview

Harris’ bed bug spray is highly rated by most of its users, and it’s been said to kill bed bugs very fast.

What you need to know, however, is that despite all the praise it receives, it doesn’t kill instantly – actually, none of the bug killers on the market kill the bugs instantly; it takes some time.

Instead, this product will, over some time, kill most of the bed bugs in your home/ office or car. That said, it’s important to note that bed bugs are a big health problem, and if there is a bed bug infestation, you may want to seek help from professional terminators, especially if you’d like to get rid of the bed bugs completely and still sleep in your house without feeling squeamish. So, in as much as the bed bug sprays work, they aren’t the best possible solution for keeping the bugs out.

So, why is the Harris Bed Bug Killer regarded as one of the most powerful solutions to your bed bug problem?

Features of Harris Bed Bug Spray

To determine how efficient a product is or isn’t when it comes to killing bed bugs, the first important thing to look at is the active ingredients that are incorporated into the bed bug killing formulation.

In the case of this Harris bed bug spray, you’ll be happy to know that it receives great praise because it’s formulated with some of the most powerful bed bug killers. While there are multiple chemical ingredients and formulations that are used to kill bed bugs, these are some of the most effective ingredients, and you find them in this spray.

This bed bug spray has also been shown to be effective in killing pyrethroid-resistant bed bugs.

So, what’s in it?

Imidacloprid – this is one of the most powerful systemic insecticides that acts as a neurotoxin. It belongs to the class of chemical compounds known as the neonicotinoids, and it kills bed bugs by acting on their central nervous system; specifically, it acts on the receptors of the insects’ nervous system forcing neurons to fire continually until they fail. It is a synthetic form of nicotine, and since bed bugs cannot build resistance to the compound, it works great in killing bed bugs. This compound is also the reason why while most bed bugs develop resistance to other chemicals, they are always sensitive and susceptible to this class of compounds.

D-Phenothrin – this is a synthetic pyrethroid that’s shown to be quite effective in killing bugs. Although bed bugs tend to build resistance to pyrethroids, the function of this pyrethroid lasts longer, and it kills bed bugs more effectively thanks to the incorporation of an active synergist, N-Octyl bicycloheptene dicarboximide, which though lacking pesticidal properties intrinsically, works to enhance the function and potency of the D-Phenothrin.

Thanks to these ingredients, this bed bug spray will kill bed bugs quite fast, and you won’t have to worry about them building resistance to the ingredients.

These ingredients are also EPA-registered and safe for use in homes and around pets. Just make sure to follow the instructions on the label.

Unfortunately, this Harris bed bug spray lacks other ingredients like desiccants and pyrroles that boost the power of the bed bug sprays. With this in mind, you may want to explore the entire range of the Harris bed bug killing products, including the powder, to enhance the effectiveness of the treatment and for the complete eradication of bed bugs.

You will be happy to know that these active ingredients and the bed bug spray are EPA-registered.

The bed bug spray is meant to be used as a spot treatment, which means that it allows you to target the cracks and crevices, as well as harborages that the bed bugs could be living in. Using the spray, you can target box springs, bed frames, clothes, furniture, empty dressers, closets, wall molding, wallpaper edges, luggage, etc. It also allows you to spray the bed bugs directly, where possible.

The other feature that stands out from this bed bug spray is the fact that the spray is an odorless formula that is also non-staining. As a result, you don’t have to worry about the spray causing damage to fabrics, furniture, or surfaces after application.
