Do you know what the number one question was we were asked this summer? How to get rid of roaches! One of our popular posts is our homemade ant spray, so readers want to know about other insects too. Especially roaches!


I just used a bunch of this homemade spray because a random trail of ants showed up on my front porch, and I didn’t want Amelia to get in it. I spray it to safely kill the ants and and things like roaches. It was safe for her, safe for the dog, and killed the ants.

To INTENSIFY this solution:

If you have larger roaches to deal with, eliminate the water in the solution above and replace with additional vinegar. This means the solution will contain 4 cups of vinegar, 3 tbsp dawn, 3 tbsp salt. I have used it on small roaches and it kills them instantly.

    This is the exact formula to get rid of weeds You just need the vinegar to kill the ants. Nothing else just the vinegar.
