Boric acid is all the rage when it comes to insect infestations. This ingredient is supposed to be a miracle killer that gets rid of insects without all the chemical fumes of synthetic products. But is it really all it’s cracked up to be? We’ve done some research into the answer.

Is Boric Acid the Best Killer for Roaches?

Boric acid is one of the most effective roach killers on the market. This powdery mixture of water and boron is highly toxic to cockroaches as soon as they come in contact with it. By contrast, it tends to be relatively harmless for pets and humans.

Some boric acid solutions are available already mixed. You can also create your own insect killer at home using attractants that are proven to be effective on whatever species of roach you’re dealing with.

#1. Zap-a-Roach Boric Acid Roach and Ant Killer

Check Price

Zap-a-Roach is a company that specifically creates products tailored toward roach killing. They have powders and insecticides that can suit a variety of different circumstances, environments, infestation levels, and types of roach. This pack of two bottles is their boric acid insect killer.

Each of the bottles has a pound of powder in it. If you’re dealing with a particularly large area or multiple infestations, you also have the option of buying the product in packs of three or six. The formula is non-staining and safe to use on all surfaces. It doesn’t have an odor, and it doesn’t leave behind chemical fumes or residue.

The goal of the product is to eliminate infestations of tough pests like ants, roaches, fleas, water bugs, and silverfish. Rather than being built to attract the bugs, this ant and roach killer is meant to be spread in the places that bugs like to go. If you know what crevices and cracks the insects often crawl out of, those are the best places to start.

The non-staining nature of the compound means you don’t have to worry about ruining appliances, flooring, or baseboards with the powder. Even nice finishes and wallpaper can stand up to the powder. Boric acid is one of the most popular solutions for residential insect killing since it’s poisonous to insects without being corrosive to varying home surfaces. It’s a great choice when you want to maintain your home integrity and not need to do any fix-it projects.

Like many other boric acid solutions, one of the selling points of this powder is that it doesn’t come with the chemical fumes or noxious side effects that other pesticides have. Your home won’t smell like it’s being fumigated. Family members and friends will be unaware of the pest problem being combated.

To use the powder, you just have to shake the bottle to mix the contents well and then twist the cap until it opens fully. Hold the bottle at an angle 45 degrees from the surface. When you squeeze it, powder should flow unobstructed. If you have crevices, cracks, or other areas that are difficult to reach, you can use a spoon to scoop the powder into them.

The manufacturer recommends applying the killer liberally. In addition to packing crevices and cracks, you can put the powder behind large appliances like refrigerators and stoves, under and behind your drains and pipes, and in any remaining unsealed corners of your baseboard. Rather than using a lure, this product contains 100 percent boric acid. You can mix it with an attractant if you want a trap that will draw the roaches in.

Boric acid is toxic to pets and children if ingested. You shouldn’t use it in places that your pets or children can access it. You also shouldn’t use it in areas where food is processed or prepared, like your kitchen counters. The residue can be very harmful if ingested.

#2. Florida Laboratories Granular Boric Acid Powder

Check Price

For people who want to buy boric acid in bulk, this solution from Florida Laboratories is a great choice. It’s made completely of boric acid that has been compressed into a fine, granular powder. Each of the bags comes with five total pounds, making it a more economical purchase than the previous option on the list in terms of quantity. The bag is labeled for you to create your own insect repellent solution using the boric acid as the killer and a bait of choice as an attractant.

The bag and the powder are both flame retardant. The powder has been tested and proven to have a 99.9+ percent purity rating in terms of the boric acid, which means it hasn’t been mixed or cut with other ingredients. Other terms for the same form of boric acid include boracic acid, acidum boricum, and orthoboric acid.

Florida Laboratories has been improving and developing formulas for more than fourteen years. The company researches products by putting them through rigorous testing mechanisms in their high laboratory quality assurance standards. The boric acid offered here is one of the raw materials that is often used in tests at the lab. It comes packaged in a food-grade, resealable, heavy duty ziploc bag that allows you to reseal and open the bag following every use.

Because the powder doesn’t come in a bottle with a squeeze tube, it may be more inconvenient to maneuver if you want to use it straight. However, this is the best powder packaging if you need the boric acid as an ingredient for your own DIY solution.

The powder should be kept away from children. If the acid contacts your eyes or skin, you should wash them with running water. If you accidentally inhale the powder, move into the fresh air. If the acid is accidentally ingested, you should drink enough water to dilute the material, and seek emergency medical help if any adverse symptoms occur.

The manufacturer recommends that you wear basic lab safety gear when mixing your own roach killer. That means gloves, loose fitting clothes, and goggles. It’s also recommended that you wear a protective mask if there’s heavy dust. No instructions or measurements are provided, so you need to know what you’re doing.

#3. Harris Boric Acid Killer Powder with Lure

The Harris insect killer is the main one on the list that also contains a lure. If you want a roach killer that both attracts roaches and kills them, this is the one for you. Other powders can be mixed with attractants at home, but the Harris formula is convenient and proven to be effective.

This is an affordable option with sixteen ounces of powder in every bottle. As long as you keep the area dry, the powder can continue to kill silverfish, water bugs, palmetto bugs, and roaches on contact for several weeks after the first application. When an insect contacts the powder, it will die within seventy-two hours.

There are other convenience features as well. The bottle allows for easy application, with a squeeze top that evenly applies powder along cracks. There’s even an extender straw for hard-to-reach crevices and other areas. The food-grade lure draws roaches out of hiding. This product has been registered with the EPA and is manufactured in the United States.

Final Thoughts

The Zap-A-Roach ant and roach killer is one of the best options on the market if you want something that’s affordable, effective, and high in quantity. Every package comes with two bottles, each of which has one pound of powder. The solution can be placed on cracks, crevices, and areas that are full of pests. In addition to being non-staining and safe for all surfaces, the solution is totally odorless.

If you’re dealing with a huge roach infestation, a number of different insect infestations, or an unusually large area, you might appreciate the Florida Laboratories boric acid. This granular powder comes in five-pound bags that allow you to create your own killing solution. You’ll need to add any attractants to customize the killing powder to suit your needs. If you don’t mind creating the solution yourself, this powdered bag of boric acid has more than enough to handle a huge amount of area.

For those who want a boric acid powder mixture that includes an attractant already, the Harris roach and silverfish killer is your best bet. Every bottle comes with sixteen total ounces of the powder. As long as you keep the application dry, the powder can continue killing roaches, silverfish, water bugs, and palmetto bugs upon contact. The powder is fast-acting enough that any insects coming into contact with it will perish within three days. Since the lure smells like food, it pulls the roaches out of hidden crevices and hiding places.
