Put the bowl in areas where you’ve seen flies or cockroaches — under the sink, behind the fridge, near the trash can, or in the corners of your kitchen or bathroom.
4. What Happens Next
Within an hour, the smell (strong to us, but unbearable to pests) will drive away flies and cockroaches. Garlic and onion act as natural repellents, while vinegar and baking soda break down their scent trails and disrupt their habitat.
5. Repeat as Needed
Replace the mixture every couple of days for continued effectiveness. Over time, you’ll notice fewer and fewer intruders
