How long does it keep in the containers?
Hi Paula: I'm thinking maybe a month or so. But, it's supposed to keep mosquitoes away for a couple of months, unless it rains:) Here is a site that may help. I'm not a fan of essential oils:
Hi Paula. I'm Cindy. I did a bit of reading so that I could answer your question properly. Most DIY mosquito repellents are good for 3 - 4 months. I read the list of the three ingredients (mouthwash, Epson salts, and stale beer) and I think these ingredients would last a lot longer on their own. I also read that this recipe keeps all kinds of insects out of your yard for at least 2 months. Good luck with this Paula. Keep us posted on how it went for you. Best wishes being sent your way.
I would make a new one each season.
