Cheap & Easy Homemade Ant Spray

793,109 Views
One of the most viewed chemistry tips post on Chemistry Cachet is this homemade weed killer (link in blog post below). Readers love how effective and easy it is to make. I have also used it to kill bugs! It works amazing to kill ants especially.

Over the last few months, I have modified it up a little to be an amazing and easy homemade ant spray!

The reasons I changed it up is to make it a little better for killing ants on any surface without leaving as much of a residue. Although this homemade weed killer is fantastic for killing bugs outside, it can leave a little salt residue behind in the home.

Remember! This for ANTS! For the weed killer, Click blog post link and we have it linked in article numerous times. We keep having readers asking why we don't share the weed killer, we have!!! Just click the blog post at the bottom.
Time: 3 Minutes Cost: $025 Difficulty: Easy
Ingredients:
2 cups of vinegar, distilled
2 cups of water
3 tablespoon blue Dawn dishwashing liquid
3 tablespoons table salt
Spray Bottle (For the best spray bottle options, please click blog link below)

NOTE::::I've had people saying they've used this for weeds. This is NOT our weed killer. It has completely different ratios with addition of water for the chemistry of it. Please read the FAQs on our website to see the difference between this and weed killer!!!!!! People keep asking for the weed killer recipe, please read the blog post. We've linked weed killer 4 or 5 times for you. Also, this is not really for other bugs. You're welcome to try it, but this is specifically for ants.

Directions
Mix ingredients together, add to a spray bottle.

Shake well before spraying each time.

I use blue Dawn for all my solutions on Chemistry Cachet because it has worked better for me. You can use any dishwashing liquid you have on hand, but I prefer Dawn

**You might be wondering why we use so many of the same ingredients for solutions....it is all about the RATIOS and the Chemistry!! You can stock up on cheap ingredients like this and create hundreds of solutions, like the ones in our book and on our website.
TO USE:

Saturate the area the ants are crawling. They die in a few seconds. Make sure to spray the entire pathway they have used too.

Allow the ants to die, then wipe the area off with a paper towel! The lingering vinegar and dish soap scent deters them from coming back to this area too. Make sure to wipe surface to prevent any possible residue.

FOR FIRE ANTS: it will kill the ones around the home. For outdoor fire ants or mounds, you might need to use a lot more of this solution.
Chemistry Tips on Homemade Ant Spray

I know readers love understanding the reasons we use certain items in our solutions, so let’s discuss the chemistry behind this ant spray.

Vinegar & Dawn Dish Soap

Why do we use acetic acid and a surfactant like Dawn dish soap? Be sure to click here for the chemistry behind it!

Table Salt

Sodium Chloride, table salt, is another favorite addition of mine. Did you see this post on salt? Salt has a interesting chemistry, but it also enhances the effects of acidity. By adding salt, you increase the effectiveness of this solution.
Without water, salt won’t dissolve well. Like I mentioned above, our homemade weed killer doesn’t contain water, so the salt doesn’t dissolved completely. This is perfect for sticking on weeds and killing them. For an ant spray, you don’t necessarily need the salt pieces, just the salt water.

    How cool! Too funny, just before reading this post I had a minor ant attack in the kitchen. I grabbed the first thing I had handy - rubbing alcohol. Now going to go mix up a batch of your magic potion just in case! Thanks! 👍

    I even use this to kill wasp. Salt and vinegar and dish soap go along way. Thanks always for new and clever ideas. Have a great day!

    You can also just put food grade Diamacious earth on ant Hills. As the ants crawl on it their exoskeleton is scratched and they dehydrate and die.
