B Natural Pure Cold Pressed Water Soluble Neem Oil Concentrate for Plants & Garden 250ml with Free Measuring Cup |for Making 50 Neem Spray Bottles for Plant Insects | Effective with 3 in 1 Formula

this is a cheaper way of buying this oil, just mix what you need. The bottle will last a long time.

Bought this as my house plants were infested with small flies. Completely changed compost, then started treating with neem oil. Make up solution, soak compost and spray leaves. I have found that I have to treat every few days but will keep at it till all flies and larvae destroyedUpdate.Losing battle. Really couldn't control the flies. Ended up getting rid of 3 plants as the flies drive me mad.

Can't praise this stuff enough, its amazing and i will never use anything else again, its also fab for human ailment’s

Well I thought I'd give this a go. So far after 2 treatments, sum of the little buggers are still alive.Uf you quadruple the dose it starts to work eventually.

I used a hand held pressure sprayer. Before spraying tomatoes there was a cloud of white flies, the next morning you could count those left. As suggested I sprayed a week later to allow for eggs hatching and am down to very few if any flies. Tried it on my Lillies which had a red beetle attack. No more red beetles. I would say that as an oil based product vigorous shaking when mixing is required. Also I run some hot water with washing up liquid through the sprayer after use as I can see that it will clog up.

Seems to be working.

Got this to kill off small black flies that had infested a potted lemon tree that was in the conservatory. The leaves were covered in sticky sap which was dripping onto the furniture and all over the floor. I took the advise of another reviewer and put a single drop of washing up liquid in the spray bottle (a reused cleaning product) before mixing the oil and water in it. It mixed fine and sprays easily.I'd advise spraying it outdoors and letting the plant dry before bringing back indoors, it is an oil and does tend to go every where. I've used it 3 times on the tree, a few weeks apart each time, and so far it looks back to normal with no bugs or sap showing.You only use about 5ml in a spray bottle, and that will be enough for about 100+ plants, so at this rate I think the bottle will outlast the life of the plant if not me !!

The only thing is it washes off in heavy rain, so it needs reapplying if you’re dealing with slugs. Works as a one-off with black/greenfly.
