Forget the new Neem which you get today isnt good. Except you have a old flask of Neem, this one works but not the new one. I had thrips (only some bugs) with the new Neem, it doesnt work after one week. I buyed a second one, spraying again, nothing happened. Until i found the old flask which i buyed 10 years ago, spray it one time and all bugs are gone. Same happens to a friend. (the new one looks like rapeseed oil and the old one looks like a dark olive oil)
A seller says to me, "today the Neemtree is rare and now the tree is protected" - that means, difficult to get the good old Neem and no effective Neem i can buy in my country. Dont know if its true but he says that to me. You also can buy a Neemtree or a Neem-cuttings and put it in your room or tent.
I think i write a similar text, either I have not sent it or it has been deleted but the last text was better in my english
But the perfect way to get the insects down is a spray mixture 100 years old and harms no plant.
1. put a hand full tobacco in half liter water for one day.
2. next day buy some chilli, onion, ginger, garlic put it into 3-5 l water and mix it with a blender, you can take all kind of food which is hot or/and have a strength odor
3. put the tobacco juice (without tobacco) in the salad dressing (i mean the mixture)
4. spray it
5. the rest give into the fridge, it should hold 1 week in the fridge but after one week you should make a new mixture.
You can make it without garlic, cause the garlic odor is very heavy.
