There are absolutely no chemicals present in this product and it’s totally safe for you to use around pets or even children! Many people don’t really understand what makes diatomaceous earth pet-friendly, but it’s all about how this stuff works.

You see, diatomaceous earth isn’t something poisonous, which means it doesn’t need to be eaten to work. Instead, diatomaceous earth absorbs the oils and fats from the cuticle of the roach’s exoskeleton, causing the cockroach to dry out and die.

HARRIS Diatomaceous Earth Food Grade is OMRI listed (Organic Minerals Research Institute). You can rest assured that it was produced against strict organic standards. This pet-friendly roach killer is made in the United States. More specifically it’s mined in Nevada and packaged in Georgia.

Be careful not to put too much powder in the duster to avoid clogging at first use. Also, you should make sure the powder stays as dry as possible so it remains effective for a long time.

If you find it too messy to use the duster since it may create a dust cloud that lingers in the air for a bit, you can apply the product with a tablespoon instead.

You see, boric acid doesn’t kill cockroaches immediately upon contact. Instead, it takes a couple of days for the powder’s effect to kick in.

Boric acid interferes with the digestive system of the roach. When roaches ingest the powder, boron from boric acid builds up inside of their bodies and interrupts their life systems since they can’t digest or excrete this compound.

Boric acid affects the roach’s metabolism and hinders its ability to take up nutrients. This results in the inevitable death of the insect from starvation or dehydration. The HARRIS Roach Killer Powder gets the job done within 72 hours after initial contact.

Moreover, this power offers a long-lasting effect because it sticks to the skeletons of roaches which carry the substance back to their colonies, affecting other roaches that you don’t see.

How to Choose the Best Pet Safe Roach Killer

When choosing the best pet safe roach killer, there are a few points that you should take into account so you can make the right purchase.


Right off the bat, you should be looking at the list of ingredients in the roach killer’s description or the one printed on its packaging.

If you want to find a roach killer safe for dogs, or just about any pet, it should be free of toxic chemicals that you’d usually find in commercial-grade insecticides.

Instead, look for products made of natural or organic materials since these are almost always pet-friendly roach killers. But still, don’t believe the “natural” claim until you read it.

Such roach killers typically contain essential oils as active ingredients, for example, rosemary and peppermint oils. Most of the time, these products won’t only kill cockroaches, but they’ll also help keep them away.


This refers to how the product is applied. If you’ve been shopping for a cat safe roach killer or any pet-friendly product for that matter, then you’ve probably come across different methods of application.

Sprays are the conventional way to use insecticides, which means it’s practically foolproof. All you need is to direct your spray at the roach once you see it, or use the spray in crevices and cracks that you suspect roaches to be hiding in.

It’s a pretty simple approach, but the downside to sprays is that they usually have an overwhelming odor. Even if they’re organic sprays with somewhat pleasant scents, you may still spray too much that it becomes overpowering.

Insecticide powders are also rather common when it comes to getting rid of roaches. They’re fairly simple to lay down, however, if you’re not careful, you may end up with quite a mess.

Such powders are typically equipped with dusters or puffer bottles to make application easier. But some users prefer relying on a spoon to sprinkle the powder to avoid creating insecticide clouds.

Types of Roach Killers to Avoid

While the above-mentioned guides can really help you choose the best pet safe roach killer, there are certain types of roach killers that you should avoid if you have a pet at home. Here are the main ones:


Sprays are one of the most common ways to get rid of cockroaches. However, they can be quite dangerous to use when pets are involved.

For starters, sprays can be harmful if inhaled by your pet. I mean, we humans can get rather dizzy and unable to breathe if we inhale just a little too much of a commercial spray, so imagine what it can do to an animal!

The thing is, even if you avoid using a spray while your pet is around, the spray will coat different surfaces around your house. Once your pet comes in contact with these surfaces, the toxic chemicals will stick to its paws. Your pet may end up ingesting these dangerous substances if it licks its paws or grooms its body.


More intense than sprays, foggers are highly potent insecticides that should never be used in a closed space with humans or pets trapped inside. These products spray contact insecticides from the center of the room and into the air, aiming to penetrate into the trickiest spots where cockroaches hide.

Obviously, you should remove your pet from the premises when using a fogger.  But even then, the insecticide will continue to oppose a risk due to the toxic residue it leaves behind. If your pet licks such substances off its paws or body, the side effects can be really dangerous.

Additionally, your cat or dog may eat a dead cockroach. In this case, your pet will also be ingesting some of the used insecticides.

Bait Stations

Many people consider bait stations to be pet safe. Unfortunately, most manufacturers don’t actually make such claims.

While the idea of confining bait inside a station sounds effective to keep toxic substances hidden from your pet, you can never be too sure.

Such stations typically contain large amounts of bait, so what if your pet finds its way into one? It’ll surely get sick and no one wants that.
