I don’t know you but I even don’t like vinegar in my salad. Hoping the same for cockroaches!
Although vinegar is being used as a more natural alternative to bleach in cleaning, it is not exactly a cockroach killer. If you intend to drown a cockroach in a glass of vinegar. most likely it will kill it but this doesn’t mean that you can spray the whole kitchen with vinegar and get rid of cockroaches. Sorry..
But as a countable cleaner, it will definitely going to be a good supporter of your roach battle. Not sure if it will help you to kill the bacterias that the roaches are spreading like salmonella.
If I would have to make a selection between bleach and vinegar, most likely I would go with vinegar. Specially it helps a lot for getting rid of the bad smell that comes from the sewer.
Still wishing the roaches also hate vinegar..
