Homemade Roach Spray (Good for Ants and Other Bugs Too)

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.

Ingredients:
- 2 cups of vinegar, distilled
- 2 cups of water
- 3 tablespoon dishwashing liquid
- 3 tablespoons table salt
- Spray Bottle
Directions:
- Mix ingredients together, add to a spray bottle.
- Shake well before spraying each time.
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.

Cinnamon works very well. Only problem is it is not safe for dogs. You have to be very careful where you sprinkle it. If you have a dog and you are putting it where the dog might walk and get it on their paws they could lick it off their paws.

Does this work for fleas
Do you know if this works on gnats and is it safe to spray in potting soil around plants? Ran into a gnat infestation in my Chameleon enclosure which has also now spread to my tortoise habitat. It's so frustrating, and I'm trying to find something safe to use around them. I can't do too much with the tortoise enclosure since he's crawling in the very dirt the gnats are starting to get into, but maybe I could find something that is safe to use for him.
