Perhaps you are reading this because you just discovered a cockroach at your house for the first time. It’s a crisis, right?
Nobody would argue that they are creepy and disgusting to look at, but another reason to get rid of roaches from your house is the fact they they can carry bacteria and even make your allergies worse – according to research at the University of Kentucky.
Quick Look - Best Roach Killer Baits
We’ll explain more about methods for effectively getting rid of roaches, and then provide a comparison chart to help determine the best roach killer available to the public.
Top DIY Roach Killing Solutions
For some more gory details on exactly how roaches can give you food poisoning, the University of Nebraska points out that roaches feed on garbage and food. They transfer germs by crawling across your countertops, silverware, and the like.

In the process, those germs can end up being consumed by you and your family – sometimes resulting in food poisoning. So if you were thinking a few roaches could be “out of sight out of mind” then you should think again. Killing the roaches in your house is really something you need to do.
Preventing Roach Infestations
As the old saying goes, an ounce of prevention is worth a pound of cure. And while the list of best roach killers on the market above can help you once roaches have been spotted, a few common sense preemptive actions can help keep them out to begin with.
Cockroaches love warmth and food. That sounds a little bit like us humans. They also enjoy moisture. So any empty containers such as boxes, bottles, etc. should be cleaned up and set out to the trash in a timely manner. Allowing those things to pile up will bring the roaches in for certain. As simple as it sounds, cleaning up properly and promptly will go a long way to keeping roaches out of your house.
Another handy tip in a story told on the Huffington Post is if you do find roaches, don’t simply smash them and let them lie. Others will come out and eat up the remains, as gross as that sounds. So if you are doing some self-exterminating, be thorough in your clean-up lest you attract more of the same.
In order to see how well you are preventing cockroaches, the simplest step to take is a visual inspection. According to this article from Purdue use a flashlight and check the most common places: behind the fridge, under the sink, cracks in cabinetry and dark corners wherever they may be found. If you do find the presence of roaches, then it is time to take action.
Killing Roaches With Bait
A few of the items in our list above are a variety of roach baits. Baits typically include a slower acting insecticide with the purpose of attracting the pest, then giving them time to go back and share the poison with their friends. There are several advantages to bait:
- Readily available and relatively cheap
- No mixing, prep work, or inconvenience – they come ready to use.
- Generally contained in a pet and child safe container
Even the best roach bait will have limited effectiveness if not used properly. Many kits are sold with about a dozen bait stations in a pack.
In most cases you should use all the bait at one time. Since kitchens and bathrooms are the most common areas of the home, that might breakdown to 8 bait stations in the kitchen and 4 in the bathroom or something similar.
Placement in the rooms themselves is also important.
You should always place them in corners of the room as opposed to in the middle of a wall or the middle of a room. Also under sinks, in any damp/dark areas are great places to put extra baits. You want to think about where the roaches are most likely to be and place your baits there. It is also important to not “overkill” by spraying a liquid bug spray on or around your baits.
Remember that the goal of a bait is to get roaches to come to it, and mixing a killer or repellent nearby might reduce the bait’s effectiveness.
Using Bug Spray To Kill Roaches
Insecticide sprays are also featured on our best roach killer comparison chart above, and again they are only as effective as how they are used.
You should note that often roaches will not die immediately after being sprayed. However, if you still see roaches a week or so after spraying then you likely need to take further action.
No matter what, you shouldn’t forget the prevention steps mentioned above in conjunction with spraying. If you don’t take care of the basics, it is just a matter of time before you have a problem again.
Another thing to keep in mind with spray is that it often acts as a repellent for awhile (assuming the spray isn’t applied to a surface that gets cleaned often). This means roaches probably won’t come back to the spot you sprayed very soon. However, a thorough application is critical as roaches are smart enough to simply move to an untreated area.
In these cases, a bait-spray combo may be a great solution.
Does Boric Acid Kill Roaches?
If you are looking for a simple, DIY solution for killing cockroaches then boric acid is a great fit. That point is fairly common knowledge, but often people have no idea how to distribute and apply boric acid properly.
First, note that boric acid will be effective indefinitely as long as you don’t get it wet. Another point is that while it kills roaches with ease, it isn’t nearly as harmful to children and pets. You wouldn’t want to snack on it for fun, but it is a relatively safe solution for your home.
As far as proper application, many people go overboard. We tend to assume that more is better, and the opposite is true in this case. If you have a pile of boric acid in the corner, roaches are likely to avoid it completely.
Instead, you want a really light dusting in the area you want to treat. Think about when you have a bottle of baby powder upright, and give it a decent squeeze. That puff of powder that goes up should put you in the right mindset for how much boric acid to put out to kill roaches.
Remember, the lighter the better when it comes to boric acid.
