Yearly Guide & Report


Are you looking for cheap natural ant killers but you’re not sure which product to buy? In order to find the best solution for your household and your needs, you should first identify the most important features of such a product. Here is what to look for to make sure you found an effective natural ant killer.

Opt for organic ingredients

Chemicals may be the easiest way to get rid of pests but they can also pose a serious threat to your health and to the environment. Luckily, Mother Nature has provided us with everything we need in order to create powerful pest repellents using natural, organic ingredients.

So, what is a good natural ant killer? Essential oils such as peppermint, lemongrass, cedarwood, and orange all come with powerful properties that not only help you get rid of unpleasant odors, grease, and stains but can also remove pests once and for all.

It is important that the formula you are opting for is 100% natural and organic to not cause allergic reactions or health problems afterward. We also suggest choosing products that are biodegradable and won’t pose a threat to the environment either.


Targeted solutions

What makes a good natural ant killer? Most people would agree that a product that promises to deliver a solution for all your pest problems would be more convenient. However, often enough, these sprays or powders don’t target an exact type of insect, meaning they are not 100% efficient.

Each insect is different and reacts to various chemicals, compounds, and ingredients, so you shouldn’t assume that what might get rid of your ant problem might also help you remove bed bugs, mites, fleas, ticks, and other pests. Therefore, it would be better to opt for products that specifically target ants to avoid future disappointment.


Powders vs. sprays

If you want to find the best natural ant killer for outdoors or indoors, you also need to pay attention to the way the product is presented.

Powders, such as diatomaceous earth, are very popular because they are easy to use and affordable. They don’t need to be mixed with water or other ingredients and can be easily sprinkled around the affected area.

However, as many customers mentioned, this solution is rather messy. Apart from sprinkling the product inside the narrowest corners of your house and in any potential hideaway, the powder may take up to 48 hours before you get to see results, depending on how bad the infestation is.

Powders can also be easily blown away by the wind, even when you apply them indoors, meaning you need to pay constant attention to the places where it ends up to ensure their efficiency.

On the contrary, spray formulas and concentrates can be applied both indoors and outdoors with the help of sprinklers or hoses, so that they cover a larger area at once. Unlike powders, sprays start acting immediately, meaning you can kill ants and other pests on the spot.

If you still have doubts regarding the most suitable product for your household, we suggest you go through some online natural ant killer reviews and read the opinions of other customers.
