This is what I have:

1) Half a clove of garlic.
2) Olive oil.
3) Some white onions.
4) A packet of extra hot chili powder.
5) Neem oil.

Now how should I go about making my bug killing spray? I have no appropriate soap for neem oil so that is out. What should I do next?

Also if it helps, I am growing mint, basil (lemon, sweet and Indian), coriander, garlic, curry leaves, magnolia, jade, sunflower and Cestrum nocturnum.
The insects I get are mostly flies, little mosquito type insects and spiders.
So I need a spray that will get rid of all of them

Any help is appreciated.

Thank you.

That said, someone in your part of the world (Australia) is more likely to be of help. Perhaps that someone will pop in.)

But some questions:
1. How many of each kind do you see?
2.What sort of damage are they doing? (For instance, flies don't make holes.)

A comment: In my part of the world, many a fly fits in one of these categories:
- beneficial (help limit other insects)
- nuisance value to people but an important part of the food chain
- seasonal critters that can be ignored

1. How many of each kind do you see?
I would say a dozen of the small / mosquito type ones during the day on average. As for flies, about half the amount.

2.What sort of damage are they doing? (For instance, flies don't make holes.)
Well I am worried about flies laying eggs. The other damages include holes in leafs, increase in the number of insects causing some small spiders to make their webs over my plants and strangely enough, some of the leafs turning yellow.

I can stick with what solution I get, so the critters can go away (I have not noticed and beneficial ones yet)and once I get the proper type of soap, I can use neem as neem would be effective in the long run.

As for neem oil, is any dish washing liquid usable? The one I have is Unamat dish washing liquid, lemon scented. It is: phosphate free, biodegradable and grey water safe. Standard strength I think.

So you suggest mixing neem oil with warm water then? Nothing more? Because I got my neem oil bottle from an Indian shop and it says nothing much of importance at the back really.

And thank you for your replies, I have been following some of your other posts, very helpful!

And there's the problem. We don't know, without proper directions on a label, how much to mix with how much water and how much soap. All I could comment on is that this type of product won't make a solution in water. I wouldn't use it at all unless you can track down some directions.

I live in Australia, so I guess buying online would be the only option. Any info?

I managed to find and buy Eco-Neem ... all I had to do was mix it with water as indicated. I drenched my garden and surrounding ground with the solution. That should be enough for a week eh?

Also, I noticed that my chili plant's leaves were so weak that they are starting to fall off. The colour is getting "lifeless" green I think. Is that normal or did the pests do it?
I have given it plenty of fertilizer and water before.

So I have heard and just witnessed spiders making their nets on the leaves and the pots! Is neem oil supposed to repel spiders as well? I hope so. I just killed some relatively big spiders from some of my bushy herbs - mint and basil. I am paranoid now, if I should use those leaves or just burn them.

HELP!

But then again it has been raining here a lot, and I keep my important plants and herbs under a shade to avoid the neem oil being washed away, but I have to put them back since they need water eventually.

And I suppose the dampness would explain why there have been so many insects =/ It sucks, having both these pests.
