One of the most viewed chemistry tips post on Chemistry Cachet is this homemade weed killer. 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.
This version is better for that PLUS you can use it to kill ants around your plants without harming them either since this is more diluted.
