Non-Toxic Ant Killer



When the ants come marching in, make this non-toxic ant killer for the win.

The other morning, Xan and Evie sat down at the breakfast counter in the kitchen only to find dozens of ants crawling all over.

They were totally grossed out and it was B.C. (before coffee) and I simply couldn’t move that fast.

Now, if you know me, you know I wouldn’t use commercial ant killers in the house because of the toxic chemicals and fumes. And I’ve tried the cinnamon thing and it didn’t stop ants and peppermint essential oil spray may be a great spider repellent, but it didn’t stop the ants either.


Conventional ant killers have gross ingredients like Piperonyl butoxide (PBO), Pyrethrins, and Petroleum.


Piperonyl butoxide – Piperonyl butoxide (PBO) is a man-made pesticide synergist (ingredients more effective at killing pests). By itself, PBO is not designed to harm insects. Instead, it works with bug killers to increase their effectiveness.  It can cause eye and skin irritation on contact.  Studies have led the U.S. EPA to classify Piperonyl butoxide as a possible human carcinogen.

Pyrethrins – Pyrethrins are pesticides found naturally in some chrysanthemum flowers. They are a mixture of six chemicals that are toxic to insects. Exposure can lead to wheezing, cough, difficulty breathing, and irritation of the airways.  Highly toxic to honey bees. #savethebees

Petroleum – Originally, petroleum was discovered hanging out on the bottom of oil rigs and although refined, it potentially can contain polycyclic aromatic hydrocarbons (PAHs) that have been linked to several cancers, including skin, lung, bladder, liver and certain digestive system cancers.


Raid Ant and Roach Killer contains all three of these ingredients and actually has this warning:

“HAZARDS TO HUMANS AND DOMESTIC ANIMALS. CAUTION: Harmful if swallowed or absorbed through skin. Avoid breathing spray mist. Avoid contact with skin or clothing.” (Source)


Yeah, thanks but no thanks.

You can make a simple and effective ant killer with ingredients that you probably already have in your kitchen: water, baking soda, and powdered sugar.

I experimented to see which DIY ant killer would be the most effective.  The top dish contains equal parts of water, baking soda, and powdered sugar.

The bottom left contains equal parts of baking soda (1 tbsp) and powdered sugar (1 tbsp) but only half part water (1/2 tbsp).

The bottom right contains only equal parts of baking soda and powder sugar.  No water.

As you can see, the bottom left was the winner.
