Which are the best pet-safe roach killers for you?

Diatomaceous Earth DE10, 100% Organic Food Grade Powder – Best Overall Pet-Safe Roach Killer

This is regarded as one of the best pet-safe roach killers, and it is a top-recommended solution by professionals. The top reason why this product is regarded as one of the best options for killing cockroaches has to do with the fact that your pets can ingest it, and it won’t cause them any harm because it is 100% non-toxic. Interestingly, pests found to have ingested pesticides are treated using Diatomaceous Earth.

The effectiveness of Diatomaceous earth comes from the fact that this roach killer is made of diatoms. Diatoms can be defined as the remains of algae, the organisms living in freshwater bodies. They are fossilized skeletons that contain silica. With time, the diatoms settle at the bottom of the ocean, lakes, or rivers, where they are mined and turned into a fine powder. The diatomaceous Earth comes in super fine powder, with the same consistency as baby powder.

First used as one of the effective remedies for bed bugs, Diatomaceous Earth is now one of the most effective and the safest roach killers.

Also, you will be happy to know that Diatomaceous Earth is quite easily available. All you need to do is to make sure that you use food-grade Diatomaceous Earth because this is the version that’s not toxic to pets. And since this product is also used in pools, it could be chemically-treated and not an excellent option for the prevention of roaches.

How do you use diatomaceous earth to kill roaches? First, you’d have to sprinkle a coating of the compound on the surfaces where you may have seen the roaches hiding or foraging indoor spaces. For the easy application of the SE in small quantities and to reduce the messes, you may like the 2-liter food-grade DE shaker bottle. You could also buy the 2lbs or the 5lbs DE treatments if you are looking for an effective roach killer on a tight budget.

You will be happy to know that the quality of DE10 we are looking at is made of the best quality diatomaceous earth deposits, which are processed using the best quality stainless steel equipment.

Also, it’s made of 100% organic ingredients minerals and regarded as a food-grade roach killer that works well to ensure the safety of your pets.

HARRIS Boric Acid Roach and Silverfish Killer Powder – Best Long-Lasting Performance

Borax is regarded as one of the best roach powders on the market, with the only caveat being that the roaches might not eat it. What this means is that in as much as borax kills roaches, this will only happen if the roaches eat it.

Borax is pet-safe as a roach killer once it has been ingested. Borax is part sodium (table salt), and it works because once the roaches swallow it, they will be dehydrated. This often works because roaches tend to be dehydrated quite fast, meaning that the roaches wouldn’t have to eat much borax for them to die.

Also, borax kills the roaches whenever the roaches crawl over the borax powder, which then coats the roach’s legs, which means that once the roaches move back to their hiding places, they’d start to eat the borax dust from the body from which point they would be dehydrated and die. Notably, the use of pest killers that cause dehydration is also the reason why most ants and roaches stay close to water sources.

If you have used diatomaceous earth before, the instructions for the use of boric acid are similar, and you don’t have to worry about the safety of your pets.

This Harris borax roach killer is long-lasting, and it will continue to kill roaches, water bugs, palmetto bugs, as well as silverfish weeks after its application and for as long as the borax application remains dry.

It is also fast-acting, and the roaches will die off within 72 hours of contact or intake of the borax powder. And for more effective results, the container’s puffer bottle fitted with the extended straw ensures simple application, especially in the hard-to-reach areas.

It also boasts an irresistible lure that will attract the roaches from the dark places they are hiding from. You may also like it because it is made in the USA, and EPA-registered, also safe for use in homes, around people, and pets.

Buying Guide for Pet-Safe Roach Killers

The search for the best pet-safe roach killers can feel tumultuous. However, it doesn’t have to be, especially when you ask the right questions. For example, are you aware of the three main types of roaches that exist? With the list of the top-recommended roach killers covered above guiding you on the best roach killers that will not harm your fur babies, we now take a look at the important considerations that point you in the direction of the best options for pet-safe roach killers.

I know what you are thinking – how could there possibly be more than one type of these pesky creatures? Isn’t one species more than enough for roaching in the world? Well, first, there evolution, the survival of the fittest, and the consequential diversity of nature. Unfortunately, this is not the kind of diversity that you need in your home, and to keep your pets safe, you’d have to find the roach killers that target these three types of roaches effectively.

Known to thrive in warm and dark places, including unkempt houses, these are some of the types of roaches you may have come across:

These are just some of the common types of roaches, but there are about 17 other types of roaches.

Any of the three types of roaches can be killed using roach killers that come in the form of sprays, repellents, or traps.

The traps, for example, beer traps, would be placed in areas of the house where the roaches forage the most. These are the bait stations, and like your rat traps, you’d have to check the traps each day. You could also use sprays in the form of foggers or aerosol sprays, or even non-insecticidal roach repellents. You could also use foggers.

At the end of the day, the effectiveness of the roach killer you choose and the safety of your pets depend on the ingredients that make up the roach-killing formulation. What this means is that your focus needs to be on organic compounds and nothing toxic. Although a number of the products that are claimed as safe for your pets might not be safest, and you have to pay a little more attention to the ingredients label/ specification when looking for cockroach killers. Your best options are often as simple as peppermint and rosemary essential oils, boric acid, or diatomaceous earth.

Your pets could be very sensitive to smells, meaning the roach-killer you choose shouldn’t have any harsh or intense fragrances. Avoid products with intense fragrances.

You’ll agree with us that the one thing that is a little more annoying than the roaches is a roach killer whose effectiveness seems to last for only a minute! It makes you wonder why manufacturers would make an ineffective product.

Well, here is what you need to know about roach killers – how long the roach killer lasts is dependent on factors like how fast the active ingredients in the formulation would last and also the amount of product used. Now, for the most part, the most effective roach killers carry an efficacy of up to 1 month (minimum) and a maximum of 2 years. In case of big infestations, you would, however, need to use additional traps.


Roaches are pesky, unattractive, and you feel queasy every time you see them. Unfortunately, they tend to be as persistent as they are a nuisance, and getting rid of them proves challenging when you have pets. So, to save you the trouble, we researched extensively, giving you the best possible recommendations. As seen above, diatomaceous earth is one of the best and the most effective pet-safe roach killer. It is non-toxic, and it actually works. Boric acid also makes an excellent roach killer, and if you only wish to repel the roaches from the drain, for example, you may want to use an essential oil spray (peppermint) because roaches don’t like the peppermint smell.


Can you use tea tree oil to kill roaches?

Though tea tree oil is one of the most popular essential oils that’s been said to kill roaches, it is ineffective, especially because roaches are too fast for your essential oil spray, and also, these annoying bugs repopulate too fast. It is said that for every roach you kill, there are ten more in the walls.

Are there DIY baits that you could use to get rid of roaches?

Yes. If you are thinking about a safe, DIY option to save money and get rid of roaches, you will be happy to know that you could use a mixture of ½ cups sugar and ½ cups baking soda. Mix these two ingredients together in foam or plastic cups, then pour in the infested areas.

What makes pet-friendly cockroach killers?

The best pet-safe cockroach killers are made of organic products/ ingredients. Besides diatomaceous earth and borax, other effective remedies include essential oils like citronella, cinnamon, cedar oil, eugenol, clove, citrus, rosemary, mints, and garlic, among others. The essential oils work by disrupting the neurotransmitters of the target insects. These neurotransmitters are absent in pets, people, and other vertebrates, hence the effectiveness of the essential oils in killing roaches. And although the botanical oils are rather naturally-occurring toxins that are extracted from plants, they are naturally broken down very fast, which is why they are a safe and effective solution. The only catch is that you’d have to apply the botanical products frequently.

Why are regular roach killers unsafe for pets?

Though the roach killers aren’t as toxic to pets as they are to roaches, most of the active ingredients used in the chemical roach killers are the same ones used to rid your cats and dogs of fleas and ticks. Since your fur-babies lick their fur and paws off often, it wouldn’t be safe to use the chemical-based roach killers – they may not cause death, but they often result in life-threatening intestinal issues. Some of the toxic active ingredients include fipronil and zinc phosphide.
