Killing Cockroaches the Natural Way

This post has been edited Oct. 11, 2016 to erase one ineffective recipe with a different one 🙂

Love thy neighbour… But not the freeloaders that came with him!
Our new neighbour moved in with some unwanted baggage – roaches. YUCK!

I am calm at the sight of blood and most other things that lift people’s blood pressure in general, but when it comes to some critters, I scream bloody murder! (OK, this was not intentional, but did you notice I used the word ‘blood’ three times in one sentence? I promise, there will be no more blood in this post:) Cockroaches do that twice to me, because I think they’re dirty.

I need to get rid of them ASAP – the more you wait, the more (cockroaches) you gain. But I don’t want to use any chemicals, especially now with baby in the house.

So I turned to my trusted resource – essential oils. I used to have them for cleaning and skincare a lot before I was pregnant, then I avoided most of them during pregnancy (I will explain more in some future post, there is a lot to say) and when my son arrived, I still didn’t use them as much as before to make sure he won’t get some reaction. Now with our new tenants, I’m rolling my sleeves up and I will spare not one!

Roaches and most other insects hate the smell of some essential oils (chilled citronella, Mr. Mosquito?). So spraying a well diluted mixture of the right oils can serve as a good prevention. Peppermint oil is quite universal, combined with other oils, it’s da bomb! Roaches in general hate citrus oils and mint oils (spearmint, peppermint etc.) and die on ingestion.

Preventative spray for roaches:

  • 1/2 cup of water
  • 8 drops cypress oil OR tea tree OR citronella oil
  • 10 drops peppermint oil

Cockroaches killer spray (if they already invaded your precious home):

  •  1/2 cup saltwater (1 tbsp sea salt in 1/2 cup water)
  • 10 drops cypress oil
  • 10 drops peppermint oil

Mix your oils and water in a spray bottle and spritz corners and hideaway places in your home (roaches tend to like dark and moist corners). Spray also your entry door frame to cut them off before they knock!

I have previously (before the Oct. 11, 2016 edit) recommended a different recipe that turned out to be quite ineffective. Well, here is something we tried and it worked: diatomaceous earth. You can apply it anywhere in your house except for areas that are consistently damp or wet. Apply along any places that can be an entry way for the bugs, where food and food remnants can be dropped; and seal off any cracks or holes where they could be hiding during the day.

You can also add cotton balls with Thieves blend into AC vents to purify your air and assure that roaches won’t be hiding there.

Happy ‘hunting’!

When using essential oils, exercise precaution like with any other chemicals. They are very (I should type VERY) potent and can be harmful to pets and children if swallowed. Do not spray on food, dishes or near open food containers.

As a source for good quality essential oils, I recommend Young Living Essential Oils.

  1. Its true i was taking bath using peppermint soap in it. Then rinse my body with water then suddenly a cockroach flew in the shower fell on the rinse water with peppermint on it then it just stop moving at all.

    • That was probably due to more than just the peppermint. I’ve seen roaches run across unscented soap bubbles near my kitchen sink & die from that. And seriously, I think that any creature that can be killed by SOAP of all things shouldn’t be allowed to exist. Ever.

  2. The roach motel is supposed to trap them, no? And peppermint oil is supposed to be a deterrent? So, why would putting peppermint oil in the motel actually lure them in?

    • Hi, thanks for the point. I have since updated the post with a different recipe. The motel didn’t work like in the post I modeled it after, so I didn’t feel like it should stay on my page. Thank you for reading 🙂

  3. First off, thank you so much for posting this information. How often do you need to spray with the roach killer? Once a day? Every other day? Once a week? I’m just curious, because I’m use to putting several drops of peppermint oil on cotton balls once a day & I really want to get away from that.

    • Hi! First, it needs to be sprayed more often, once you are sure they are gone, it just a “maintenance” issue. Once a week (or two). Make sure they don’t have an entryway back in (holes under the doors, cracks etc.) and that they don’t have a REASON to come back – uncovered food lying around, crumbs on the floor overnight and similar occurrences.

  4. If peppermint repels the roaches, why would they enter a container soaked with peppermint soaked on the cotton balls?

    • Hello! Is the salt properly diluted? Or too much salt? Some sprays get clogged just with water use (or not really clogged, but stop working because of cheaper plastic that wears down). Try skipping the salt and using distilled water or hazel witch, if you have it around.

  7. I personally have not used Diatomaceous Earth but I have read a lot about it. It is deadly to insects but should be used with care. You should add a side note saying not to use it in places where beneficial insects (honey bees, ladybugs, etc…) can get to it. Inside your house is fine but not in gardens and flower beds. Thank you.

  8. Hi I live in GA .. Yes one of the breeding grounds for ROACHES. I hate them. I have tried so many things and end up using Raid and as we all know that adds up. I bought that peppermint pear away spray and it drives me away more than the roaches. I’m fed up and worn out. Please PLEASE HELP ME……

  9. that; really odd – you mention that mint and citrus work against cockroaches, but none of the oils you suggest is from a mint or a citrus. Why is that?

    • Peppermint is from the mint family. You can also substitute with Spearmint or Wintergreen (same family), but Peppermint is most easily accessible essential oil.
      There are many recipes that I haven’t mentioned, perhaps it’s time for another cockroach post 🙂 You can use lemon wedges in places with cockroaches, the smell alone repels them.

    • You need to identify which ways they’re coming in and block their entrance. Put diatomaceous earth across their paths. Try spraying more often than the company sprays.

  11. Something I was told by an exterminator is that peppermint oil works to repel rats and mice because it interrupts their senses so they wont cross it. Maybe this is the same for the roaches.
    I can’t wait to try the remedies. I have seen a few tiny ones, and I know their in the buildings because my neighbor warned me. If I can keep them from coming out of the walls I will be fine with that. I literally lose my appetite when I see one, it makes me feel like my whole kitchen is dirty.
