Buying Guide for The Best Cockroach Killer Spray

As you expect from a product group that contains extremely toxic pesticides, choosing a cockroach spray for your home could include many factors that require consideration. Just going for the most powerful and effective spray is not always the finest choice. And since we all have diverse situations around us, it is even harder to just commend a cockroach killer spray without addressing how and why we have chosen them and how you should select your next bug spray buying.

Thus, if you are looking to find a new bug killer spray option, here are the things we think you should consider first.


Chemical or Natural

There are the two main groups of roach sprays you will find online. Both have their advocates plus both groups of advocates tend to throw embroidered arguments and overgeneralized facts at each other. The simple fact is that both kinds of roach sprays can work fine and do their job, but their works are just different.

Where extremely toxic bug sprays are meant to directly kill existing heavy cockroaches or bug invasions, natural repellents are more of a preventive measure.

Suppose you have just seen a couple of accidental cockroaches in your home. In that case, a good natural roach spray could effectively repel the pests beforehand they have even spread.

However, if you face a full-blown cockroach attack or the natural spray is not offering sufficient protection, you need to consider a stronger chemical option. These products do have the negative disadvantages of often intolerable smells, along with health risks for your pets and kids if direct contact has been accidentally permitted. But they are sometimes the merely effective measure against significant bug problems.


Type of Roach Killers

There are three kinds of cockroach sprays, which are-

i. Surface Sprays

They offer longstanding control and can be applied on dustbins, shelves, crevices, etc. Surface sprays attack the roach’s nerve function with synthetic pyrethroids, producing paralysis and death.

ii. Traps and Baits

Traps and baits offer extensive roach control and are effective while used along with a surface spray. They comprise indoxacarb, which enters the roach’s nervous system and blocks sodium channels, instigating dehydration and death.

iii. Knockdown Sprays

Knockdown sprays contain a parallel key active ingredient but help target a single cockroach at a time and remove them instantaneously.


Active Ingredients

Roaches are best demolished with chemicals. Though pest control authorities have limited the use of damaging substances for home usage for safety purposes, there are still some toxic ingredients like fipronil, abamectin B1, Pyriproxyfen Indoxacarb, and Hydramethylnon, which can be deadly even in a few percentages.



Best Roach killer sprays are neither the costliest products nor the most often used ones. As such, price differences between diverse brands might not be as crucial, but it still does not hurt to keep them into consideration.

Do not forget to compare the prices with the product’s durability. A cheap product that requires reapplication every month is considerably costlier in the long run than a more expensive product that needs to be sprayed twice a year.


Safe For Pets and Kids

When seeking the fatal roach spray, be certain to check if the product has been labeled to be kid or pet-friendly. Most of the roach sprays comprise harmful active ingredients that are not good for your children.

Some ant roach killer products are safe for kids and pets, but since they still have deadly toxins in them, thus it is safer for you to keep them away from the ingredient in all cases.

In the state of an emergency, take your kid to a doctor instantly. While maximum roach killers are harmless while they contact the human skin, however, if ingested, they could have adverse significances.


How Quickly It Works

An essential issue to consider while buying a roast killer is how fast it works and removes insects, roaches, and bugs. Most of the roach sprays start working immediately and remove the roaches inside a few hours. Others may take some time. Make sure to read the reviews of a product before purchasing it.


Length of Efficacy

This factor specifies how long the roach killer products could work. Usually, the length of efficiency of an ant roach killer depends on two things— how fast the active ingredient will break down and the quantity of product you are applying. The maximum of these products has at least one month of effectiveness. At the same time, the maximum efficiency of the products is two years.

Sometimes, the big infestations need additional sticky traps. The poison could be consumed too fast, as many stubborn german cockroaches are engulfing it. Before applying the product, you need to check the directions given on the package of that spray. With this, ensure that you have checked the time while the product needs to be replaced.


Brand Name

The brand name is very important sometimes. To help you out, here are the brands that we would advise you to consider first: Bengal, Black Flag Dry Ant Killer, Harris, Aunt Frannie’s, Ortho, Wondercide, Combat, and Hot Shot.



The best roach sprays do one thing well for most people: it stops a sprayed roach in its tracks with the fastest knockdown. As a bonus, a good spray keeps killing any cockroaches that come upon for days otherwise, weeks afterward, that first spray.

Select one that meets your requirements: nontoxic sprays for pet proprietors; residual sprays -focused for widespread applications; fast knockdown for anyone who does not want to chase a half-dead roach underneath the fridge.
