Does Killing A Cockroach Attract More?

It’s hard to resist the rage when you see a cockroach. 

The moment you see it, you want to crush it to death. 

When you make the roach meet its destiny by squashing it, there’s one less roach in your home.

And then, you observe a few more loitering around the place where you killed the roach!

But does killing a cockroach attract more? 

In other words, do dead cockroaches attract more roaches?

Keep reading to find it out.

Does Killing A Cockroach Attract More Roaches?

does killing a cockroach attract more

In all honesty, it does. 

Cockroaches are cannibals. They won’t shy away from eating their dead. 

Roaches are so cannibalistic that when food and water are scarce, they’ll eat even their babies. 

Why do roaches do that? Why do dead roaches attract more cockroaches?

Well, that’s how nature designed them. 

Roaches are scavengers. Their appetite is diverse. 

Cockroaches can eat anything from organic debris like rotting leaves to decaying flesh. 

This eating habit does wonders for the ecosystem. 

Roaches eat the waste and release them back to earth, which in turn enriches the soil. 

Talk about how roaches benefit the planet. Now you know how!

But there’s a catch here.

Cockroaches don’t eat their dead immediately. 

It’s because when you squish a roach, the glands of a dead cockroach leaves behind oleic acid and pheromones. 

The oleic acid emits a smell which is a warning signal for roaches. It tells the cockroaches that there’s a threat around. 

With time, the smell goes away. 

But there’s more to it.

But the smell of the pheromones, which roaches use to communicate and to attract a mate, don’t go away.

When you kill a cockroach, the glands that emit pheromones bust, causing a splash of pheromones on the floor.

That attracts the other roaches. 

So, is there any way that you can use to stop a dead roach attract other cockroaches?

The following section will answer your question.

How To Stop A Dead Roach Attract Other Roaches?

Now that you know why a dead roach can attract other roaches, it’s time to understand how to stop it. 

Thankfully, it’s easy and simple to do it. 

All you’ve to do is remove the dead roach and dispose of it away from your home. 

Don’t dispose of the dead roach in a trash bin inside your home.

It’d be best if you discard the dead roach away from your home and yard.

Second, clean the surface, where you squished the roach to death, with a disinfectant. 

For better results, you can also add a few drops of peppermint essential oil to the disinfectant. Roaches hate the smell of peppermint oil.

The disinfectant will get rid of the pheromones splattered out of a dead roach.

No smell of pheromones means no cockroaches will reach the place where you killed the cockroach.

That’s how you can stop the dead roach from attracting other cockroaches.

You can stop the roaches from eating their dead. 

But can you stop cockroaches from eating their babies (nymphs) and eggs?

Sure you can. But you’ve to get rid of roach nests and infestation in your home. 

So, what makes the nymphs such an easy target for adult roaches?

Why Do Adult Roaches Eat Their Nymphs?

Adult roaches eat their nymphs

When it comes to eating, nymphs are not adult roaches’ first choice.

Adult cockroaches eat their nymphs when food and water are scarce in the dwelling that they’re infesting. 

One of the first methods that pest controllers use to control roaches is cutting off the food and water sources of the cockroaches.

This method is known as exclusion. 

So, when there’s something similar going on inside a human dwelling, that makes the roaches look for “alternative food.”

And what’s the first thing that is nearest to them if they’ve got a nest?

It’s the nymphs or baby roaches.

Cockroach nymphs are defenseless against adult roaches. 

The nymphs are not fast enough to escape. And their underdeveloped exoskeletons are weak.

That makes these nymphs are an easy target or, in other words, an easy meal. 

When roaches don’t get food and water, they can eat their eggs too.

And, no matter how disgusting it may sound, roaches can eat their poop too.

These are the qualities that have made roaches crawl the planet for more than 200 million years

Can You Kill A Cockroach By Stepping On It?

Yes, you can. But killing a roach by stepping on it or by crushing it under your boots isn’t as easy as doing the same to ants.

Roaches are one of hell of a resilient pest.

At least seven out of ten times, a roach isn’t dead when you stomp on it. 

You’ve to put in some effort to kill it. 

Next time when you’re crushing cockroach to death, make sure that you stomp on it hard at least twice.

And stomp on its head at least once, real hard. But, please, don’t do it barefoot. 

At least put on a slipper or flip-flop. 

And do not forget to dispose of the dead roach and clean the surface with disinfectant. 

Else, the dead roach will attract other cockroaches, and ants too.

So, Should You Kill A Cockroach?

Yes, of course. 

Roaches carry bacteria that can cause diseases. Also, exposure to molted roach skin and roach eggs can cause allergies to many people.

These can also cause asthmatic attacks in asthma patients.

But there are better ways of killing a roach rather than stomping on them. 

You can’t go around chasing every cockroach inside your home to crash it to death. 

Roaches hide in the tiniest of cracks in the deepest corners of your home where you can’t find them. 

The better and long-term solution to keep roaches away from your home is to make your home unattractive to them. 

Here are a few ways to make your home unattractive to roaches –

  • Keep your home, especially the bathroom and kitchen, clean.
  • Ensure there’s no food waste in your home, not even in the trash bins.
  • Keep your yard clean. Your yard is one of the places from where roaches sneak inside. Wood cockroaches also enter your home from the yard.
  • Keep your drains unclogged. Sewer roaches use the drains to get inside your bathroom. 
  • Caulk gaps and cracks in your home’s walls, doors, and windows with a silicone-based sealant. Roaches can’t chew through it. 
  • And, most importantly, ensure there’s no water leakage in your home and yard. Water leakages increase dampness in your home. That attracts roaches and many other bugs.

Roaches also hate the smell of peppermint and eucalyptus essential oils. 

On top of making your home unattractive to roaches, spraying essential oils like peppermint in your home will emit a smell that cockroaches hate.

That’ll keep roaches away from your home.

What Kills Roaches Instantly?

What kills roaches instantly

There are many ways to kill roaches instantly and without touching them

Making dough balls mixed with baking soda and keeping them on a roach bait is one way. 

Baking soda kills roaches.

Sprays like Raid roach-killer is an effective spray that kills cockroaches on the spot. 

Pyrethroid-based sprays like Bengal Gold also kills roach instantly.

But you’d need to spray it on the roach directly. That’s certainly a better option than to squish it.

Pouring bleach in clogged drains kills roaches hiding in the drains. 

So does pouring white vinegar mixed with hot water.

But keep in mind that bleach is corrosive and can damage the drain pipes. Use the bleach sparingly and not that often.

Sprinkling diatomaceous earth in the hiding places of roaches also kills the cockroaches. 

Diatomaceous earth penetrates the roach’s exoskeleton, dries up the moisture inside its body, dehydrates the cockroach, and kills it.

But remember, roaches are resilient and tough to kill. 

These methods will only work if the infestation level is low. 

If the infestation is heavy, which would be evident by roach smear marks and roach smell, it’d be best to hire a pest controller.


Dead roaches attract more roaches. Killing a cockroach and not disposing of the roach’s body is a sure way of attracting more cockroaches.

In this guide, you’ve found out the reason behind roaches being cannibals. 

So, next time if you crush a cockroach to death, or if you see a dead cockroach, get rid of the roach’s body and clean the surface with a disinfectant.
