Top 5 Best Roach Killers You Should Use to Kill Roaches Effectively

Choosing the Best Roach Killer

To fully understand which product is the best, you are going to need to know what is available. Professional Grade Concentrated Pesticides

These formulas aren’t just used by the professionals, but also many homeowners as well. Why? Because they are effective and work fast.

Concentrated pesticides are contact killers. Once the cockroach comes in contact with the poison, they will die within seconds.

Roach Baits

Having the roaches help to kill one another is the best case scenario. Using baits allows for that to happen.

Whether you use a gel or bait station, the concept is the same. Most of them use boric acid as the active ingredient.

The roaches come and eat it happily because of the attractant that is added in. Then, they take it back to the nest with them to share with others.

Once they’ve all eaten of some, they will die.

Boric Acid

This all-natural solution for killing roaches has become a favorite. For some people, Borax powder is a little easier to find and generally sold in the laundry aisle.

To apply these products, simply spread a light layer of dust wherever roaches travel. When the cockroach makes his way through the powder, it will break down their exoskeleton.

This product works great when mixed with a little sugar water to create a bait.

Diatomaceous Earth

This all-natural and non-toxic product offers results for those who want to avoid pesticides. It gets applied in the same way that the boric acid did and offers many of the same results as well.

Reviews of the 5 Best Cockroach Killer Products

What’s the best roach killer? Here are the top 5 best roach killer reviews for your consideration.

1. Advion Syngenta Cockroach Gel Bait

There isn’t a product more heavily reviewed and recommended than this Advion Syngenta Cockroach Gel Bait. That’s why it is so easy to determine this is the best roach killer for indoors or outdoors.

Advion is a high-performing bait product that targets all pest species of cockroaches. The Syngenta Gel Bait offers the MetaActiveTM compound.

In addition, it combines a high-consumption bait matrix with the potent, non-repellent active ingredient for maximum effectiveness. Cockroaches are unable to resist the lure to this combination.

Advion offers entry holes into the baiting arena designed to target both the large and small cockroaches invading your home.

This product is ideal for use indoors or outdoors. It is often used in commercial, residential and industrial sites.

Advion is available to purchase as 1 tube or 4 tubes. Purchasing 4 tubes at a time drastically reduces the cost and makes this a killer value for the effectiveness.

Don’t just take my word for the incredible effectiveness of the product! One user was happy to share that in the month since application, it has been three weeks since there were any instances of cockroaches at all.

Another customer stated that just eight hours after application there were dead or dying roaches lying all over the house. That’s what we call maximum effectiveness worth any amount of money!

Things We Didn’t Like

  • Claims it is safe for pets, but it is still recommended not to use where they can access
  • Not for use in areas that children can reach it
  • Not for use around food preparation areas

2. Advion Cockroach Bait Station

Another great choice as the best German roach killer is this other product from Advion. This bait station provides complete control of the colonies that cockroaches inhabit your home with.

The active ingredient is indoxacarb which is a slow-acting product. This allows for the time that cockroaches can effectively transfer the poison to all the inhabitants of their colony.

Simply put, the cockroach will eat the bait. Then, they take it back to their unsuspecting house guests.

From there, the other cockroaches will touch it and feed off of it through the feces. It will effectively poison them all!

Advion’s bait station is easy to use and lasts for a long time. There is no residue or odor involved plus it is pet and child safe.

You will find it to be an effective solution both indoors and outdoors. In addition, all species of cockroaches will die when contact is made with this system. These include:

  • German
  • American
  • Australian
  • Brown
  • Oriental
  • Asian

You can choose to purchase the bait stations in a pack of 10 or 60. When purchasing the pack of 60, you are getting a far better value for your money.

Just like with the previous Advion cockroach killer, the reviews from customers have been astounding. One person claimed that within 4 weeks, the entire infestation was completely gone with no more roaches anywhere.

While this isn’t advertised, another user claims it also rids their house of scorpions and centipedes. Seems like a nice additional perk.

A common use for the baits it to use them in drawers and cupboards after the infestation is over. They seem to be a good way to maintain a cockroach-free home.

Things We Didn’t Like

  • Doesn’t kill the cockroaches immediately
  • May not work as well as the gel does

3. Harris Boric Acid Roach Powder With Lure

When searching for a more natural way to control cockroaches, you will inevitably come in contact with the Harris Boric Acid Roach Powder. It is long lasting and kills roaches, palmetto bugs, silverfish and water bugs for weeks after application.

Insects that come in contact with this formula will die within 72 hours of contact. The puffer with extended straw makes it easy to apply even in difficult to reach areas.

In addition to the boric acid, this formula offers a food grade lure that will actually attract the cockroaches out of their hiding places. This combination is registered with the EPA and made in the U.S.

It is completely safe to use in the home with people and pets. When you use this product to kill cockroaches, simply place the powder wherever you notice an issue.

The roaches will be drawn to the boric acid and it will cling to their body. Then, any other roaches that come in contact with the infected bug will also die.

You’ll notice that the powder continues to work as long as it remains dry. The nice thing about the boric acid powder is that it can also be used as a prevention method.

The easy to apply powder can be placed in any cupboard, pantry or baseboard to ensure that cockroaches never come back.

Harris Boric Acid is available in 16-ounce containers. Buying them in bulk doesn’t always necessarily lower the price, but overall, it seems to be a good value for the money.

Customers have been pleased with the effectiveness. One customer wrote that they have plenty left over since it worked so fast. Another user noted that it only took two days for the entire infestation to be gone.

Things We Didn’t Like

  • Lure isn’t as effective as other products
  • Straw can be difficult to use for application

4. Dupont Advion Cockroach Bait Arenas

This option is one of the least expensive on the market, but still quite effective. The overall cost is lower because there is less product available, probably making it the best roach killer for apartments.
Inside the plastic outer covering of the arena is where the bait sits. The covering helps keep the bait from pets.

The Dupont bait arena is a high-performing product that works against any species of cockroach. It contains the active ingredient indoxacarb and will effectively fight the following types of cockroaches and more!

  • American
  • German
  • Australian
  • Brown
  • Oriental
  • Asian

The highly attractive, proprietary gel formulation offered from Dupont offers a potent, non-repellent active ingredient. This makes the bait irresistible to cockroaches.

Once a pest has immersed themselves in the bait, they will happily share it with others in the colony. Then, your infestation is gone!

You can purchase the Dupont bait arena as a 3-pack or 12-pack, but the price difference is huge. Buying a 12-pack is almost the same price as the smaller unit, so it makes more sense to buy extra for future usage.

One customer highly recommends that you work on your evil laugh and enjoy a beer as you watch them die. Another user exclaimed that they had a new apartment since all the roaches are gone.

Things We Didn’t Like

  • Does not provide instant death
  • Doesn’t seem to work as well as the gels

5. Raid Ant & Roach Killer Insecticide Spray

Raid has become a pretty common name in household pest control, but is it worth the money? As a spot treatment and quick death of visible bugs, it is a great solution.

The Raid Ant & Roach Killer will exterminate pests on contact and provides a way to continue killing for 4 more weeks. It is also easy to apply with the aerosol can.

Keep the can handy for when a stray bug is crawling around. Many people use this as a backup method to their current pest control solutions.

The nice thing about this formulation is that is effective against many insects. This includes:

  • Roaches
  • Ants
  • Water bugs
  • Silverfish
  • Crickets
  • Spiders
  • Asian Lady Beetles

Ideally, this can work by spraying it in cracks, crevices and other areas that could be hard to reach with other pest control products. The can contains 17.5-ounces of product and offers plenty for continued use.

One user commented how this spray has no chemically smell or fumes like some other products do. Another was happy to report that Raid is the best spray to kill bugs on contact.

Things We Didn’t Like

  • Doesn’t work to kill the colony
  • Doesn’t prevent infestations

Using Roach Killing Products

Once you’ve picked the best roach killer, it is time to understand the best practices for proper use.

Why You Need Roach Killers

Roaches aren’t just embarrassing but there are several health consequences you could face from having the roaches in your home. While they don’t carry diseases themselves, they are still carriers for millions of bacteria and infectious agents.

Here are just a few of the ways that roaches might be affecting your health:

  • Food contamination
  • Spread of disease-causing bacteria
  • Biting humans
  • Invading body parts of humans and pets
  • Allergies
  • Asthma

To protect your family from these health risks while you are fighting roaches, follow these suggestions:

  • Keep your home clean
  • Clean all food preparation areas thoroughly
  • Empty trash often and keep it covered
  • Never leave food open
  • Throw away old newspaper, books and magazines
  • Spray cockroaches on site for instant kill
  • Seal tiny cracks or holes in the house

Four Cockroach Species

While there are over 4,000 cockroach species, only four of them are regularly found to be household pests.

  • German cockroach – the most common
  • American cockroach
  • Brown-banded cockroach
  • Oriental cockroach

Some people also suffer from Palmetto bugs which are wood roaches. While the article has touched on the main species, these treatments and solutions are effective when applied to any species of cockroach.

What to Consider Before Buying

You must first determine what type of product is going to work best for your needs. This will be the guiding force behind which formula you ultimately decide is best.

Make sure that you purchase enough of the product to cover the entire area you need protection against. It will do no good to apply products to only half of the area.

Next, your budget needs to be taken into consideration. There are products to choose from in every price range.

If you are dealing with multiple insects around your house, be sure to choose a product that will kill them all. There are many bug killers that work on multiple pests at the same time and it will save you some more money.

Safety Concerns During Treatment

Many people have expressed concerns over using cockroach killing products because of the chemicals they contain. Here are some thoughts to consider:

  • Many products offer low-hazard properties for pets and children
  • Applying a bait system offers small doses of chemicals that are only toxic to the insects
  • Most bait systems also offer a protective covering so it isn’t easy for children and pets to get access to the ingredients

Tips for Using Cockroach Killers

Remember to always follow the guidelines set out by each manufacturer when applying any product. In addition, before you start spraying the entire house, here are some guidelines that will help you:

  1. Determine where the cockroaches are hiding and what pattern they travel in.
  2. Treat these areas along with baseboards, window trim and doors.
  3. Treat small cracks and crevices found throughout the home.
  4. To treat behind drywall, you will need a small drill bit. Then use a small straw to spray insecticide into any hiding places.
  5. Set roach baits in appropriate places. Using baits in conjunction with sprays is the easiest way to exterminate roaches once and for all.
  6. Place baits inside cabinets, under the sink and behind appliances.

Preventing Roach Infestations

Once you’ve used the best roach killer for home, follow these tips to prevent further infestations:

  1. Put all food away in sealed containers.
  2. Remove all clutter from the house.
  3. Sweep and vacuum on a regular basis.
  4. Take the garbage out often and keep it covered.
  5. Fix leaky plumbing.
