Well after about a month of wearing this whenever go play outside with my son I can say it seems to work well. Mosquitoes seem to always bite me and I haven’t had one bite since we ordered this, either has my son who’s always playing in the grass and tall plants. I have found they do still try and land on us so I wouldn’t say the smell deters them completely but maybe just enough not to bite. I love that it’s all natural. Will buy this again when needed.
