Hello - I live in South India and I am making a garden here but the best time for us to work is in the evening when we have finished other work and it's cooler. But the downside is that there are so many mosquitoes here and often we are driven in half way as walking around we disturb them and they bite us in huge quantites... Locally I can only get chemical repellents and I dont like to use it on a long term basis. I have tried mixing citronella and tulsi oil with some coconut oil and applying it and it kind of works for about half an hour but its not super effective. I've tried neem oil also but they seem completely unbothered by it. Just wondering if anyone makes any formula that works well for at least an hour and a half or so while we garden... Thank you!!
